78 Show report | Eurosatory/UGS 2016 Milrem has integrated two new payloads on its Themis UGV. The Themis Adder uses ST Kinetics’ Adder Light Calibre RWS (remote weapons system), which can be equipped with a 40 mm automatic grenade launcher or a 0.50 calibre heavy machine gun with a 360 º and -10 to +60 º tilt. The RWS uses a colour CCD day camera, an InSb-cooled night camera and a Class 1 laser rangefinder with a range of 50 to 5000 m. Raytheon UK’s GroundEye c-IED system can also now be fitted to the Themis. It is operated from a ruggedised tactical tablet computer, and identifies objects below the ground using image processing and the creation of micro- seismic fields using laser diodes, a camera and a vibration source. The Themis consists of two remotely operated tracks joined by an empty iron base platform 2 m long with modules spanning 0.9 m to 2.1 m wide. The 750- 850 kg vehicle has a top speed of 35 kph, and carries up to 750 kg over an 8-10 h endurance period, powered from diesel generators or 80 Ah Denchi 6T lithium-ion vehicle batteries. Graphene ultracapacitors are also available, from Estonia-based Skeleton Technologies. “The ultracapacitors reduce power consumption very significantly, and during high peaks of energy use, the system takes its energy from the ultracapacitor rather than the battery,” explained Kuldar Väärsi. French civilian manufacturer Drone Volt has launched the Janus 360 UAV, which is designed for capturing in-flight VR footage. Dimitri Batsis told us that the Janus 360 can record 150 Gbytes of 360 º images over 15 minutes’ maximum flight time, thanks to its ten 4K cameras recording at 30 frames/s from a pair of Freedom360 rigs installed above and below the airframe. The airframe is a 1 kg quadcopter with 15.5 in propellers, running on two 4500 mAh 6S lithium-polymer batteries and four 25 V brushless dc motors, with a velocity constant of 475 rpm per V. Operation of the craft is handled through the 5 W Pixhawk Arducopter flight controller, which can in turn be operated through Windows XP SP3/7/8 with 32 or 64-bit CPUs. The Janus 360 has top ascent/descent rates of ±6 m/s, a maximum tilt angle of 35 º , and 150 º /s maximum angular yaw velocity. Electromechanical components producer MTC Industries & Research Carmiel has developed the ERSA-0311 redundant electromechanical rotary servo actuator. Its design has been optimised for UAV requirements such as operating in temperatures from -40 to +71 C, and incorporates EMI RFI shielding. “On average, there are between eight and 20 servo actuators in a large UAV, and now that flight testing has finished, the ERSA is to be incorporated in the Elbit Hermes 450, and hopefully the Hermes 900 as well,” said Nir Eldar. The ERSA uses dual 28 V dc brushless motors with redundant electronics through two separate control boards to provide duplicate flight control channels, as well as a three-ganged potentiometer and a high-efficiency gearbox. It can deliver a maximum torque of 25 Nm and weighs only 875 g, and is available August/September 2016 | Unmanned Systems Technology Drone Volt’s Janus 360 UAV is designed for capturing in-flight VR footage Milrem’s Themis UGV can now be fitted with the GroundEye system for identifying subsurface objects
