This is a 4WD robot that uses four of our heavy duty 120 RPM Wheel Chair Motors and our 13″ tiller tires. The wheels are mounted directly to the heavy duty motor shaft for simplicity.

High ground clearance, high payload capacity and powerful motors make this robot a workhorse. At only 26 inches wide it can fit between standard doors as well as most field crop rows.
The Enclosed Chassis is made of 1/8″ and 3/16″ aluminum plate CNC plasma cut and welded together. The robot uses differential steering (movement is based on two separately driven wheels placed on either side of the robot body).

It can thus change its direction by varying the relative rate of rotation of its wheels and “pivot turn” in place. It has 250lbs load capacity, so you can technically use it to move a person.The robot has a 5mph speed.
