The Artemis I space mission is relying on uncrewed systems to test out the technology that will see humanity return to the Moon. The project is set to deliver an uncrewed capsule to the Moon’s orbit, testing out the technologies that will carry a new generation of astronauts. The project is detailed in our Space insight (page 56), alongside another mission. That project, DART, delivered a probe to an asteroid, impacting successfully within 17 m of its target after travelling millions of kilometres. The aim is to see how such probes can deflect the orbit of asteroids that are at risk of hitting the Earth, demonstrating a dramatic new use case for the technology for the benefit of humanity. At the same time, test technology is enabling vehicles to operate autonomously. As we discuss in Platform One (page 6), ABD Solutions has taken simulation and test technology used for driver assistance systems to convert almost any kind of vehicle. That will drive autonomous operation into many more applications.

6 Mission-critical info for UST professionals Platformone ABD Solutions has developed a modular platform that can turn existing mining, agricultural and military vehicles into driverless ones (writes Nick Flaherty). Indigo Drive is a complete autonomy solution that converts a vehicle to driverless operation using a central controller. The functional safety design is based around certified ECUs to handle the autonomous operation of the vehicle Ground vehicles Modular solution to conversion October/November 2022 | Uncrewed Systems Technology on a set path with a mission plan. The conversion uses either mechanical actuators on the steering wheel, brake and accelerator pedals as well as arms to move the gears, or control via the vehicle’s CAN bus using the SAE J1939 protocol as well as an OBD2 diagnostics bus to monitor the activity of the vehicle. The underlying mechanical actuation IP comes from another company in the ABD Dynamics Group. Matthew Price, managing director of ABD Solutions, said, “We take their technology and modify the robot systems for these markets. This includes a new user interface, detect and stop sensor technology integration and modified robot actuation systems. We have also increased the ingress protection ratings to meet the operation conditions and the need for a semi-permanent installation in the vehicle.” The system is designed so that

7 Platform one control of a vehicle to keep it moving if there is an obstacle, but the main purpose is the pre-programmed operation,” Price said. The fleet management function provides constant monitoring, selecting any vehicle at any time. An operator can access the video feeds from the vehicle alongside other data such as performance, location, diagnostics and fuel levels. Cybersecurity has been designed into the system from the start. “What drives some of the technology is having the right level of separation and remote access,” Price said. “Part of that is showing that the solution meets the necessary levels of cybersecurity for the end-user.” That leads to technology choices for the server used by the operator. The server can be cloud-based but it is expected that on-site servers will be preferred for more secure applications. “The core software can manage numerous vehicles of varying types, the key constraint being the complexity of the operational environment and not the technology,” Price said. The next stage of development is to use the data for detecting anomalies. Machine learning (ML) analysis of the data feeds can potentially identify problems with the vehicles before a problem becomes critical, to allow them to return to base for maintenance before a failure occurs. However, Price points out that existing maintenance schedules would still be followed, even with autonomous operation. ABD Solutions is looking to work with partners and customers on the ML tools to achieve the anomaly detection. “At this stage the data is provided to the customer’s server, and they will use it to find anomalies themselves,” Price said. “We are not looking to do everything ourselves, and there are data analytics partners we can get in touch with to provide that technology. “We are doing the same with the electrification of the vehicles, indoor positioning and diagnostics.” Uncrewed Systems Technology | October/November 2022 ABD’s system converts vehicles such as mining trucks to autonomous operation by using a combination of mechanical actuators The pedal robot is attached to the seat frame, the steering robot is mounted on the steering shaft, and there are arms and a frame for gear changes vehicles can also be driven. “The pedal robot is attached to the seat frame and offset, while the steering robot is mounted on the steering shaft underneath, and there are reaction arms and a frame to support the gear changes,” Price said. A key requirement for the mining sector is that the whole cab is part of the safety cage, which means the system has to be designed around existing mounting points. The cabs of mining trucks also have to be sealed for air-conditioning, so heat management is a crucial consideration for the ECUs. A typical conversion uses cameras, Lidar and radar at the front and back of the vehicles and around the sides, controlled by a separate ECU. Another ECU handles secure communication of video and sensor data as well as diagnostic data back to a base station and positional data from GNSS constellations or other sensors. However, the conversion is configurable depending on the specific use case. The comms can use an encrypted redundant mesh radio technology developed by ABD Solutions, for example in a mine, or other secure military comms systems. For more costsensitive applications such as agriculture or industrial material handling systems, the link can be 4G cellular. An operator can monitor any of the live feeds from the vehicle and take control as required. One operator can monitor multiple vehicles in a fleet. “Teleoperation is part of the core technology, for example to take manual

8 Platform one October/November 2022 | Uncrewed Systems Technology Bradshaw Electric Vehicles is to use technology from Fusion Processing to develop fully autonomous uncrewed tow tractors (writes Nick Flaherty). The tractors are used extensively in factories, warehouse and airport logistics to haul baggage trailers and goods trucks. Making these autonomous can improve safety and make logistics more efficient. Fusion Processing’s CAVstar control and sensing system will be used in Bradshaw’s third-generation T700 and T800 tractors, which are based around a 48 V powertrain. CAVstar uses machine learning on a range of sensors including Lidar, optical cameras and ultrasonics to build up a picture of the environment around the vehicle, and plots the most efficient safe route through it. That means the autonomous tow tractors can be operated safely inside factories where a GPS signal is unavailable and without the need for extensive infrastructure to be installed. CAVstar can also be retrofitted to any vehicle, to control the throttle, braking and steering systems to provide full autonomous operation. CAVstar is now being used on a fullsized autonomous bus in trials in Scotland. Autonomous tow tractors Ground vehicles Researchers at Imperial College London and Empa in Switzerland have developed 3D printers that can build structures while in flight (writes Nick Flaherty). The technology could be used to build structures in difficult-to-access or dangerous locations such as tall buildings, or help with post-disaster relief construction, the researchers say. The Aerial-AM multi-robot system uses a 3D-printing UAV, the BuilDrone, with a separate UAV called the ScanDrone to monitor the quality of the build and control the main UAV in real time. These are combined with a path-planning software framework. A real-time predictive control is integrated with a dynamically selfaligning delta manipulator in the BuilDrone. The three-arm manipulator was developed for a project in 2019 and is capable of three degrees of freedom. It holds the print head and is used to compensate for the movement of the UAV; it provides a manufacturing accuracy of 5 mm. The researchers built proof-of-concept prints using a DJI M100 UAV as the BuilDrone to produce a cylinder 2.05m high consisting of 72 layers of a rapidcuring insulation foam material, and a cylinder 0.18m high consisting of 28 layers of structural pseudoplastic cementitious material. “We’ve proved that drones can work autonomously and in tandem to construct and repair buildings, at least in the lab,” said Professor Mirko Kovac at Imperial’s Department of Aeronautics and head of Empa’s Materials and Technology Centre of Robotics. “Our solution is scalable and could help us to construct and repair buildings in difficultto-reach areas in the future.” The project included researchers from the University of Bath, University College London, the University of Pennsylvania, Queen Mary University of London, and Technical University of Munich (TUM). The researchers are now working with construction companies to validate the solutions and provide repair and manufacturing capabilities. “We believe our fleet could help reduce the costs and risks of construction in the future, compared to traditional manual methods,” Prof Kovac said.

10 Researchers at the ETH in Zurich have developed a combination of ultra-wideband (UWB) and wake-up radio (WUR) technologies for UAVs (writes Nick Flaherty). An open source hardware and software design supports high-precision landing of an off-the-shelf UAV and energy-efficient operation by improving the ranging and bandwidth of wireless links. The techniques improve the energy efficiency of the localisation and data acquisition cycle by up to 62% compared with previous approaches, and reduce power consumption from 190 µW to 2 µW. By modifying the flight control software, UWB radios on the ground can be used to improve localisation accuracy on both the UAV and the sensors to allow the UAV to land more accurately on a wireless charging pad and so boost the power efficiency. The researchers developed a new, multi-stage localisation technique by fusing data from GNSS satellites, UWB and asynchronous hardware to produce a WUR receiver that is enabled by a trigger from the UAV. The UAV, in this case a DJI M100, is the ‘master’ in the network, enabling and disabling the comms with the sensor node, which has the UWB wireless interface, a sensing application and wireless charging power modules. The UAV’s power module delivers power via appropriate power electronic circuitry such as a Class E/F rectifier and transmitting coil, directly connected to the UAV’s main battery. A specific module manages the UAV’s attitude during flight manoeuvres such as take-off, hovering, cruise and landing. The application layer was designed from scratch and includes an onboard computer, sensor data storage and flight sensors. The layer provides functionalities for the UAV to improve the localisation accuracy by fusing the GPS and UWB information, as well as an ultrasonic sensor. Standalone GNSS navigation has an accuracy of around 25 cm, which is not enough for landing on an inductive wireless power unit. Instead, the UWB distance sensor provides an accuracy to within 10 cm and works from a range of 20 cm out to 100 m. The first stage of the navigation needs only the GNSS system, which guides the UAV to within 10 m of the landing pad. During that stage, the altitude could be a fixed safe level, but at the end of the first stage a maximum altitude of a couple of metres is needed. The second stage starts at about 10 m away from the sensor node’s UWB antenna, receiving only the pointto-point scalar distance. To calculate a planar distance, a precise altitude value is required, which is taken from the ultrasonic sensor. The UWB distance estimation is used to compensate the GNSS error. A single UWB distance scalar measurement, however, cannot navigate the UAV to the actual sensor node’s location. A 2D gradient descendent algorithm is then used, with consecutive UWB measurements adjusting the flying direction. The ultrasonic sensor is then used for the height control. This is all implemented on a PCB that measures 70 × 70 mm, combined with the external UWB antenna of 30 x 40 mm. It is UWB-compliant to IEEE 802.15.4-2011 for two-way ranging and data transfer at rates of up to 6.8 Mbit/s in addition to Bluetooth 5.0. An onboard STM32WB55RGV from STMicroelectronics manages all the stacks and sensors. Combo boosts radio range Airborne vehicles Orolia has developed an atomic clock that is small enough to fit into a UAV (writes Nick Flaherty). The mRO-50 Ruggedized is a microwave optical double-resonance miniaturised rubidium oscillator. It provides a one-day holdover of less than 1 µs and a retrace of less than 1-10 in a 50.8 x 50.8 x 20 mm form factor that takes up only 51 cm3 of volume – about one-third the volume of standard rubidium oscillators – and consumes only 0.36 W of power, one-tenth of other timing systems. With an operating temperature of -40 ºC to +80 ºC, it can provide accurate frequency and precise time synchronisation for mobile applications such as military radio pack systems in GNSS-degraded or denied environments including underwater and in uncrewed systems.

T-Motor The Safer Propulsion System Power makes your exploration www.tmotor.com UAV maker Manna is using a collaborative robot (cobot) for an automated battery swapping system (writes Nick Flaherty). Vikaso used a UR10e cobot from Universal Robotics, and programmed it to replace the battery pack in a Manna UAV. The UR10e has an arm with a reach of 1300 mm and can handle a payload of up to 12.5 kg. For the project, the arm is mounted on a linear track to move between the UAV and the battery module storage. A machine learning framework is used to identify the battery, storage rack and battery socket. The arm then removes the battery pack from the UAV and places it in the rack. The vision system then identifies a charged battery in its storage socket where it is charging, lifts it out and moves to the UAV to insert it. The UR10e is equipped with force and torque sensors to detect collisions with any part of the robotic arm, which also protects the UAV. One cobot can support two landing areas from one track and storage rack. Manna is already using UAVs to deliver payloads of up to 2 kg to customers in Ireland over a 2 km range, and the automated battery replacement is intended to speed up that process.

12 A European project is set to demonstrate secure data comms across multiple national borders for driverless cars (writes Nick Flaherty). The moveID project, led by Bosch, is developing standards and technologies to allow driverless cars to communicate independently without having to rely on particular cellular networks. This is particularly difficult when moving between different countries, and the demonstration will take place across France, Germany and Luxembourg. Current satellite networks used for cross-border trials have a latency of 600-700 ms, which is too long for autonomous vehicles. Instead the project will use a technique called a distributed ledger that is used in blockchain for distributed data without the need for an intermediary. Rather than a cellular network, the ‘infrastructure partners’ for vehicles would be charging points, barriers, traffic lights and parking lots. That would allow driverless cars to provide information about levels of traffic, available charging points or parking spaces, for example. The data exchange required would also enable traffic control based on the volume of traffic at any given moment. That would allow cities to regulate incoming traffic to particular areas in real time, thus preventing congestion. However, this method, known as zoning, requires that vehicles can immediately recognise changing conditions and change route accordingly. This zoning is being demonstrated with test vehicles for the first time across the three countries in the Merzig/ Saarbrucken area. The cars receive dynamic information about their approach to defined zones. The project will use internationally recognised hardware and software to develop management and administrative services. “An integrated and transparent system architecture for the exchange of data on the road that incorporates different products and technology providers simply isn’t available at the moment,” said Peter Busch, project manager at Bosch. “While it’s true that some companies already offer services, they are tailored for specific applications, vehicles, or customer groups. That means open standards are needed so that users for example can find all the available charging stations or pay for charging processes.” The project aims to make use of the European GAIA-X system, which defines the technological, economic and legal framework for a secure and trustworthy data infrastructure. GAIA-X relies on decentralisation and the interaction of different cloud providers under common guidelines. The project also includes equipment makers Denso Automotive, Continental and Airbus, as well as blockchain technology developers Peaq Technology, ecsec, 51nodes, Bigchain, WOBCOM, Chainstep and Datarella as well as data centre operator Atos Information Technology.

Flying-Cam has used 3D printing to develop a tail rotor actuator for its latest UAV (writes Nick Flaherty). The actuator is built using a powder bed fusion (PBF) process with the Windform XT 2.0 carbon fibre-reinforced composite from CRP Technology. This has been used for the Discovery singlerotor uncrewed helicopter, which has a 75 kg MTOW to carry payloads ranging from high-resolution cameras to remote sensing equipment for BVLOS missions. Windform XT 2.0 has an 8% greater tensile strength and 2% greater tensile modulus than the previous-generation material, as well as a 46% increase in elongation at break. Flying-Cam has also worked with CRP Technology on the former’s SARAH 4.0 eVTOL uncrewed system, 3D-printing the airframe structure, air-guide cooling system, tail unit and main battery connection. “The tail rotor actuator is clamped on the tail boom and supports the carbon plate used as a tail rotor ground protection,” said Emmanuel Previnaire, CEO of Flying-Cam. “For this reason, a good stress resistance was needed. “The clamping strength depends on the construction material’s capabilities. We chose Windform XT 2.0 as it allows us to achieve that with a good weightresistance ratio.” “Using 3D printing and composite materials gave us the ability to create complex wiring channels with strong attachment points, in one piece.” 3D-printed rotor actuator Airborne vehicles The tail rotor actuator is made from a carbon fibre-reinforced composite ENABLING TECHNOLOGY EVERYWHERE Harwin’s connector products are proven to perform in extreme conditions, with shock, vibration and temperature range rigorously tested.

14 Platform one A team from Chalmers University of Technology, in Sweden, is developing a fully autonomous UAV system for rescue operations at sea (writes Nick Flaherty). The system uses a mixture of fixed-wing and rotary UAVs with a USV to provide comms links to search an area independently, alert authorities to people in distress and provide basic assistance before crewed rescue vehicles have arrived. The USV is a marine catamaran called the SeaCat, which serves as a base for a fleet of fixed-wing UAVs that monitor the surrounding area. A rotary quadcopter can then approach people in distress and deliver items such as supplies, healthcare aids or flotation devices. The quadcopter can carry loads of up to 2 kg, while the fixedwing UAVs have a longer range to search a larger area. “The project is based on the simple principle that different drones have different advantages, and by allowing several types of autonomous drones to work together, search efficiency and rescue response speed can be significantly improved, with the potential to save more lives,” said Xin Zhao at the Fluid Mechanics Division of Chalmers. The SeaCat provides an internet uplink as well as a local comms link that is used to coordinate the UAVs in flight, and includes a launch pad for the fixed-wing versions. All the UAVs have cameras and a positioning system for autonomous operation, The catamaran follows a predefined route with a closed loop, and the fixed-wing UAVs are automatically assigned to search areas according to an algorithm that partitions an area depending on the number of them that are available and their battery power. When a fixed-wing UAV detects objects in the water, the quadcopter is sent to the scene to take pictures. The photographs can then be sent to a rescue centre on land via the USV. The rescue centre can also send out the quadcopter with supplies. When one of the fixed-wing UAVs runs out of power it lands in the water near the SeaCat, where it can be picked up and recharged automatically, then sent out again.

16 Netherlands-based Fusion Engineering has developed a flight controller designed to allow better fine path-holding and station-keeping for next-generation multi-rotor applications, by using a proprietary control methodology (writes Rory Jackson). “The Fusion Reflex flight controller contains our own hardware platform, which is the carrier for our operating system and control algorithms,” explained Robert Crone, CEO of Fusion Engineering. “The algorithms are what sets our performance apart from other flight controllers. They are based on INDI, or Incremental Nonlinear Dynamic Inversion, and are optimised for aircraft.” The core goal of using INDI was to achieve the fastest control response that a multi-rotor can handle, correcting very quickly for disturbances such as wind gusts without resulting in instabilities. To get the same performance from a conventional PID-based controller would mean increasing its gain to levels that can result in unstable behaviours. INDI algorithms are oriented around precisely calculating and implementing the dynamics required of the vehicle. INDI itself is a relatively simplified and flexible approach that uses a UAV’s accelerometers’ feedback to compute the dynamic behaviour of the system and output suitable responses to external disturbances. By measuring the difference in a UAV’s actual acceleration relative to the desired acceleration, and doing so in extremely small increments over very short periods of time, the onboard motor’s speeds will continuously and rapidly change to ensure that the next increment in acceleration is always one step closer to the acceleration the operator wants. “We have a video showing one of our test UAVs in a wind tunnel test where it undergoes 72 kph gusts while sustaining minimal deflections and very quick, short recovery times without overshooting,” Crone adds. The Fusion Reflex itself weighs 100 g and operates using two 5 V power inputs, for redundancy. It also includes two independent I2C ports, two UART interfaces, a CAN bus with two connectors, two USB ports, an SPI port and 16 dedicated ESC I/Os. A 2.4 GHz wi-fi modem is also installed. It comes with integrated tripleredundant inertial systems as well as its own internal real-time clock. A 1.2 GHz 64-bit ARM Cortex A53 processor with four cores is used as the central computer, with 1 Gbyte of RAM, and featuring 32 Gbytes of flash storage and a separate 100 MHz ARM Cortex-M4 processor for computing I/O signals and ESC rpm control.

17 Platform one Uncrewed Systems Technology | October/November 2022 As uncrewed systems become larger and more powerful, a growing number of endusers want to be able to carry multiple payloads simultaneously, but factors such as the payloads’ different weight distributions and interfaces can require extensive customisations and potentially different airframes (writes Rory Jackson). RN Technologies has therefore developed its MX-1 modular payload expansion platform, with the aim of allowing new payload modules and hence functionalities to be added more smoothly to UAVs, independently of how their airframes have been designed. “The MX-1 is implemented conformally to the shape of a UAV or other vehicle that it’s applied to,” explained Richard Neill, CTO of RN Technologies. “Each solution is designed this way to make for space-efficient integrations, following the outline of the airframe’s structure. “The electrical and electronic interfaces of the MX-1 don’t interfere with anything central to the vehicle’s operations or autonomy, and we can shape, stack or insert them in a wide variety of ways to enable a lot of plug-and-play functionality in an uncrewed system.” An example of that is a dual-gas sensor module with two separate breakouts – one for a lower explosive limit gas sensor and the other for a photo-ionisation detector system – and multi-gas sensor modules for mounting more than two instruments have also been developed. At the core of the MX-1 is a Linuxbased processor module that maintains a bidirectional comms interface with the vehicle, in order to communicate telemetry and controls between the payloads and the UAV, as well as to any GCS or cloud system. The module has dual ARM cores and 16 Gbytes of RAM. It also has wi-fi 6 installed for wireless or backup interfacing, and can support other radio link technologies for full multicommunication or mesh scenarios. RN Technologies is now working on a future version of the MX-1 in which the structural materials and electronics required would all be 3D-printed as a single, monolithic assembly. At the moment, it is experimenting with depositing silver conductive paste to form circuit traces during the printing process, for fabricating the system’s backplane electronics. Airborne vehicles One platform fits all The platform can be custom-designed to ease the integration of different payloads into uncrewed systems
