Meet Grizzly: an all-terrain robotic utility vehicle that combines the performance of a tractor with benefits of an industrial robot to take on demanding missions. Grizzly has a drawbar force of 1400 lbf and a payload capacity of 600kg.
This robot is capable of towing large payloads. It comes with 4 independently driven wheels and a passive suspension system to negotiate rough terrain. Grizzly has a modular interface, so you can attach GPS, Lidar, and other accessories to it. More info is available here.
