Abstract

The invention provides a wheel-foot hybrid robot. The wheel-foot hybrid robot comprises a robot body, first leg modules and a second leg module. each first leg module comprises a foot part and a supporting wheel; the second leg module comprises a steering motor, a first driving wheel and a second driving wheel; the leg module has two working modes: a foot mode and a wheel mode; in the wheel mode,the supporting wheels assist in supporting the robot body, the first driving wheel and the second driving wheel drive the wheel-foot hybrid robot to move together, and steering of the wheel-foot hybrid robot is achieved through steering of the steering motor. In the foot mode, the second leg module and the supporting wheels are suspended, and the feet of the first leg modules alternately touch theground so as to drive the wheel-foot hybrid robot to move. Compared with the prior art, the position transfer efficiency is greatly improved. In addition, in the foot mode, rapid steering of the wheel-foot hybrid robot can be achieved.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a wheel-foot hybrid robot. Background technique [0002] In the field of quadruped robot research, wheel-foot hybrid robot is a research hotspot in this field. When the footed movement mode of the wheel-foot hybrid robot is switched to the wheeled movement mode, the steering and driving of the wheeled movement mode have always been difficult. It is common to use the steering mode of the abduction and adduction kinematic pair of the hip joint, but this The steering method will cause a height difference between the four legs of the wheel-foot hybrid robot, resulting in a tilt of the torso, which will affect the function of other functional parts on the robot (such as detection devices, robotic arms). And the steering angle of this steering mode is limited, can't be applicable to the working requirement of small terrain, big steering angle. [0003] The authorized annou...
