The vehicle utilizes NavCom GPS technology augmenting
the standard GPS with inertial measurements, providing accurate
location of better than 1.63 ft (0.5 meter) during missions
driven under 50% canopy.
OTS based forward laser sensors and an obstacle detecting radar
at the rear form the vehicle's obstacle avoidance systems, detecting
obstacles as far as 100 ft (30 meters) away. R-Gator can be
controlled from the laptop based operator control unit, utilizing
an Xbox 360 joystick controller. The system displays and records
two video streams. Route map can be reused, utilizing route
recording and playback, reverse and repeat features, which can
also be overlaid on overhead imagery such as Google Earth.
For driving and area perception, the vehicle is fitted with
fixed drive camera and pan/tilt/zoom mast-mounted video system,
which also mount the communications antenna and GPS. The system
can assume various tasks, such as unmanned recon vehicle, perimeter
patrol vehicle, or evacuate casualties from dangerous combat
areas. As an optionally driven vehicle can be operated autonomously,
via remote control or manually driven as a normal M-Gator. It
has seats for two passengers. |
