This isn’t exactly a typical R/C toy you can play with in your backyard. This is a giant, gas powered, inchworm-killing machine.
This large, remote-controlled wheeled machine moves with either a crabbing or inching motion, and has a large vertical jaw mounted on the front that can grab and carry props. It has four wheels, though its overall shape is in a triangulated configuration. The front two wheels are separated like a normal chassis while the two back wheels are together, forming a triangle. The separated front wheels pull the machine forward; the crab-like action is a motion mechanism, which works by opposing ratchets on the wheels that change directions in opposition.
The video was cool, but this picture of the machine in action is amazing
