Tracked Chassis

The tracked chassis surrounds the drive wheel and a series of rollers on the outside of the drive wheel, so that the wheel does not directly touch the ground, but acts on the ground through the circulating track, and then drives the track through the drive wheel to realize the wheel on the track.

At the same time as the relative rolling, the crawler is repeatedly laid forward on the ground to drive the chassis movement. The advantage of the crawler chassis is that the landing area is larger than that of the wheel type, so the landing pressure is small; in addition, the adhesion to the road surface is strong, and the driving force can be provided.
