Hyundai Rotem readies Multipurpose Unmanned Ground Vehicle for delivery
by Dae Young Kim
South Korean defence and engineering prime Hyundai Rotem has been selected as the supplier of Multipurpose Unmanned Ground Vehicles (MUGVs) to the Republic of Korea Armed Forces.
Hyundai Rotem announced on 24 November that it had won a contract from the Defense Acquisition Program Administration (DAPA) to supply two MUGVs within six months under an accelerated acquisition scheme that aims to introduce new capabilities to the military. The company will also provide the associated support for the two vehicles.
MUGVs are two-tonne multirole platforms that can be fitted with a range of mission equipment depending on the user's requirements. The type can be used to perform combat reconnaissance in heavily contested battlefield environments to improve the firepower and survivability of troops.
The vehicle can also be used for supporting roles such as ammunition and expendable resupply, and casualty evacuation.
The MUGV will be derived from Hyundai Rotem's HR-Sherpa UGV, a 6×6 multirole dual-use platform that is 2.7 m in length, 1.7 m in width, and 0.9 m in height. It weighs 1.6 tonnes in its baseline configuration, and up to two tonnes when fully loaded. The company will also supply an in-house remote-control weapon system (RCWS) and plans to arm it with a 5.56 mm light machine gun.
The battery powered UGV is equipped with airless tyre technology and can turn on its axis. It is also equipped with a water-cooled battery and an integrated heat management system that supports long-distance driving in all-weather operations, and offers a claimed endurance of six hours when cruising at 5 km/h. It can also attain road and cross-country speeds of up to 40 km/h and 10 km/h, respectively.

Open source platforms, flexible airframes for new drones
Kelsey D. Atherton Designing a drone body is about settling on the right compromise. Multirotor drones excel at vertical lift and hover, while fixed wing drones are great at both distance and wide-open spaces. In February, Auterion Government Solutions and Quantum-Systems announced a two-pronged approach to the rotor- or fixed-wing drone market, with a pair of drones that use the same sensor packages and fuselage to operate as either the Scorpion Trirotor or the Vector fixed wing craft. “As we started to develop our tactical UAS Platform, our plan was only to develop a VTOL fixed wing solution (like our Vector),” said Florian Siebel, managing director of Quantum-Systems. “During the development process we decided to build a Tri-Copter Platform as well, as a result of many discussions with law enforcement agencies and Search and Rescue Units.” Adapting the fixed-wing fuselage to the tri-copter attachments means the drone can now operate in narrow spaces and harsh conditions. Scorpion, with the rotors, can fly for about 45 minutes, with a cruising speed of zero to 33 mph. Put the fixed wings back on for Vector, and the flight time is now two hours, with a cruising speed of 33 to 44 mph. The parts snap into place without any need for special tooling, and Auterion recommends the drone for missions in rain or snow. Both platforms share a gimbal EO/IR with 10x optical zoom, 720p EO video, 480p IR video, laser illuminator, IR laser ranger. Common between modes is also a tactical mapping tool using a 21 megapixel Sony UMC R10C camera. For the scorpion, there's also the option of a gimbaled electro-optical camera with a 30x optical zoom. Both drones are designed to fit in rucksacks that a person can carry one at a time. While many features are common across Vector and Scorpion, the plan is not to include both rotors or wings in the same kit. Once a team packs into the field with a drone on its back, that's the mode the drone can be used in. Auterion intends to ship the drones by the fourth quarter of 2020, with preorders available. Designing a drone body is about settling on the right compromise. Vector and Scorpion are built on top of open source code. This includes an operating system capable of programmable autopilot , as well as machine-vision collision prevention and obstacle detection and avoidance. Software for the ground station and cloud data management of the drone are also built on open source code. The Pentagon's Defense Innovation Unit awarded Auterion a $2 million contract last year to work on the PX4 software to help drive compatibility standards in the drone industry. As militaries across the world look to the enterprise sector for capable drones at smaller profile than existing military models, transparency in code and flexibility in airframe could become more widely adopted trends. In the meantime, there is Vector, and there is Scorpion. https://www.c4isrnet.com/unmanned/2020/03/25/open-source-platforms-flexible-airframes-for-new-drones
