Abstract

The invention belongs to the field of ground mobile robots, and particularly relates to a four-wheel robot with a scalable vehicle body. The four-wheel robot comprises a camera carrying mechanism (A),a vehicle body deformation mechanism (B), a first wheel telescopic mechanism (C1), a second wheel telescopic mechanism (C2), a third wheel telescopic mechanism (C3) and a fourth wheel telescopic mechanism (C4). The four-wheel robot provided by the invention can realize folding and unfolding deformation in a single degree of freedom; the vehicle body mechanism have two deformation limit positions,the adjusting range is large, and the four-wheel robot is convenient to store and transport during folding, capable of being used as a portable or throwing type robot, capable of meeting different moving requirements through deformation of the vehicle body mechanism and adjustment of the vehicle width, the vehicle length and the wheel track after being unfolded, capable of turning easily throughdeformation of the vehicle body mechanism, controllable in direction, good in flexibility and stability and good in popularization significance.

Description

technical field [0001] The application belongs to the field of ground mobile robots, and in particular relates to a four-wheel robot with a scalable body. Background technique [0002] Wheeled ground mobile robots have been widely studied because of their fast speed and stable operation. The existing four-wheeled robot body is not deformable, and the size of the body is limited when traveling or turning on narrow roads. For example, CN201711376220 discloses a wheeled robot, which drives the steering connecting rod through the motor and then drives the tire to realize steering, and the center of the line connecting the rotation center of the tire coincides with the center of the chassis shell, so that the wheeled robot can move along its own axis. Rotating, but due to its structural characteristics, the body cannot be deformed, and the excessive body size will affect its travel on narrow roads. [0003] For example, CN201710853492 discloses a four-wheeled robot, which includ...
