Robot

The invention relates to a robot. The robot comprises a robot body and a tail end executing mechanism, the tail end executing mechanism is connected with the robot body, and the robot body drives the tail end executing mechanism to rotate around a first axis; the tail end executing mechanism comprises a motor, a transmission part, a main shaft, a grinding head, a distance measuring sensor and a controller, the transmission part is connected with the motor and the main shaft so as to drive the main shaft to move horizontally in the first axis direction, the grinding head is connected with the main shaft, and the controller is electrically connected with the motor and the distance measuring sensor; the distance measuring sensor is used for detecting the distance between a to-be-polished surface and any surface of the tail end executing mechanism, and the controller is used for controlling the rotation amount of the motor according to the distance change amount. 本公开是关于一种机器人。机器人包括：机器人主体和末端执行机构，所述末端执行机构与所述机器人主体连接，
