Holy crap, check this Parralax Propeller QuadRover towing a freakin’ Toyota Pickup Truck! At $4,000, it’s a hefty investment but you can play with it by custom-programming it to do whatever you need to make it do.
This gas-powered robot is built using a Honda 2.5 HP 4-stroke engine and hydraulic power system. It is controlled by a Propeller chip for the ultimate in customizable robots; eight 32-bit cogs at 20 MIPS each create endless programming possibilities. A 64 KB EEPROM leaves 32 KB for non-volatile data storage, and ample expansion ports provide plenty of flexibility for added sensors.
Four solenoid valves allow for the hydraulic power to be independently enabled, disabled, or reversed for either side of its skid steer system. The robot can rotate in position by making a complete hydrostatic turn or by braking one side and making an arc-turn, which can be accomplished at low or high speed. Straight-away top speed is up to 14 miles per hour. QuadRover uses a two-stage pump to provide high-end torque for low speeds and lower torque at higher speeds. This transmission provides a more continuous power band than a single-stage pump system. Servo controlled throttle and disk brakes make for precise acceleration and deceleration.
