DJI is easily the leading brand when it comes to camera drones, but few companies have even attempted a ground-based mobile camera platform. The company may be moving in that direction, though, if this patent for a small off-road vehicle with a stabilized camera is any indication.

The Chinese patent, first noted by DroneDJ, shows a rather serious-looking vehicle platform with chunky tires and a stabilized camera gimbal. As you can see in the image above, the camera mount is protected against shock by springs and pneumatics, which would no doubt react actively to sudden movements.
