Gecko — RoboScout System — Unmanned Ground Vehicle (UGV)
The Land robotics system RoboScout consists of a moveable command post and two unmanned ground vehicles (UGV) called Gecko.

The Gecko can be controlled over various communication channels. There is the possibility to control the Gecko through a satellite or terrestrial radio from a plane as a relay station to increase the communication range. The commanding post can also steer the Gecko with its stationary, terrestrial antenna for close range operations. Even through a computer that is carried along by a soldier, the vehicle can be steered via WLAN on short distance.
The vehicle can follow autonomously waypoints as well. For this purpose it can follow a vehicle that is driving ahead (convoy-service), following pre-programmed waypoints (MULE-service) and drive autonomously a previously self-driven and recorded route including obstacle detection.
The usage of the UGV can reduce the danger and hazard for the deployed soldiers by taking over risky missions. At the same time the Gecko transmits reconnaissance data in real time to the command post and it can operate twenty-four-seven.
Furthermore the system is capable to operate as a communication and relay station to transmit automatically in real time various information over a long distance. This makes it possible for the deployed units to increase their transmitting and receiving range.
With the help of its high-performance surveillance platform the Gecko can operate as a location and target spotter as well as for battle damage assessment. Due to the daylight cameras and the cooled IR-camera the system is able to perform surveillances by day and night. The installed laser scanners and the GPS-system make it possible for the Gecko to measure distances up to 40 km and to detect objects.
The surveillance platform can also be upgraded with an almost recoilless remote machine gun (e.g. FLW100), a guided missile or SIGINT (Signals Intelligence — intelligence-gathering by interception of signals), and the integration of weapons and electrical interferer.

The Gecko respectively the RoboScout system can be transported by a flatbed or a trailer truck as well as with a CH-53 helicopter. The vehicle has got a hybrid propulsion with a diesel generator which provides the electrical motors with power. The alternative propulsion takes place over a lithium ion accumulator which is charged through a generator and makes in this way a noise-damped drive possible. The four electrical wheel hub motors provide the vehicle with a four wheel drive and the ability to turn on the spot.
From the operation post the Gecko is steered through a steering wheel and a brake and accelerator pedal. For a better view various cameras provide the driver with pictures which can be watched on three monitors and for navigation and location reasons an additionally monitor shows the location and the driven distance in the bird’s eye perspective on a topographical map.
|a) Terrestrial data/video links between command post and Geckos as well as inter-vehicle communication utilize VHF/UHF IP based radios|
|Data/video rate||Up to 4Mbit/s|
|b) The satelite data/video link utilizes a SOTM antenna mounted on top of the Geckos and an anchor station antenna near the command post with approximately 4.7 m diameter.|
|Method||Time division multiple acces (TDMA)|
|Data/video rate||Upstream up to 4Mbit/s, downstream 500kbit/s (point to point)|
|Polarization||Horizontal or vertical|
|c) Terrestrial service data link based on WLAN|
|A unique communication computer (ComCom) system located in each Gecko and in the command post automatically selects the best qualified available data link for the operational mission and optimises link quality and data/video rate.|
