UGV & UAV Collaboration
NREC and Sikorsky Aircraft paired an autonomous ground vehicle with an unmanned helicopter to autonomously survey sites for radiation, biological or chemical contamination.
The Extending the Reach of the Warfighter through Robotics project demonstrated that an unmanned helicopter and a driverless ground vehicle could work together to autonomously survey a contaminated site.
This joint autonomy program demonstrated the capability of ground-air cooperative missions. Such missions prevent warfighters’ exposure to hazardous conditions, such as chemical or radiological contaminated areas. Example missions that may be required include:
- Long Distance Reconnaissance
- Long Duration Reconnaissance
- Tactical Resupply
- Long Distance Resupply
Autonomous Unmanned Ground Vehicle
For this program, NREC modified a Land Tamer all-terrain vehicle with an autonomous driving system that uses technology from previous projects that have supported unmanned on-road and off-road exploration, including NREC’s Crusher off-road vehicle and the Boss SUV that was CMU’s winning entry in the 2007 Urban Challenge road race. The autonomous Land Tamer featured sensing that allows it to operate day and night under all visibility conditions and across a variety of terrains.
Optionally Piloted Helicopter
To provide the autonomous delivery vehicle Sikorsky Aircraft modified a UH-60MU Black Hawk helicopter that can fly at speeds greater than 138 mph with an 8000-pound load slung beneath it. This helicopter was modified with prototype “fly-by-wire configuration” and the Sikorsky autonomy kit, MATRIX, to deliver the UAV capabilities the program required.
These technologies were then utilized in conjunction to provide a joint autonomy demonstration that proved the capability of new, ground-air cooperative missions.
