GAIA-2 platform is designed for outdoor intelligent robot research and development using behavior-based, as well as conventional mobile robot technology. Waterproofing applied to the bottom and axles of the rugged robot allows it to run in water or mud up to 10cm deep. GAIA-2 can climb over obstacles up to 15cm high. Independent and differential drive on all 4 wheels provide a zero turning radius. GAIA-2 also offers waterproof ultrasonic sensors for obstacles avoidance.
Software access to the processor, sensors, and drive motors is easily achieved through standard interface. This interface is also used for accessing GAIA-2 options (e.g., vision system, additional sensors, actuators).
PC/104 is the default processor and two optional processors include Motorola 68332 processor (Vesta board), or XSCALE PXA-255 processor (Korebot board) by K-Team in Switzerland. GAIA-2 can be operated by remote control from a PC, notebook computer, or a workstation. Or to make GAIA-2 robot fully autonomous, a program is downloaded directly to GAIA-2. GAIA-2 robot has a wide variety of options such as people following/avoidance, light following/avoidance, and various data/video communication devices. With the optional vision system, vision-based maneuvering and landmark navigation can be implemented.
