System for adjusting torque required by robot driving device

The invention discloses a system for adjusting torque required by a robot driving device, belongs to the technical field of mobile robots, and solves the problems that the main body of the conventional mobile robot is fixed in structure, unadjustable in gravity center and too large in rotational inertia. The system comprises a counterweight, a counterweight supporting component and a counterweight moving component, wherein the counterweight is connected with the counterweight moving component through the counterweight supporting component; the counterweight can change position in a robot structure. Compared with the conventional system with a fixed structure, the system provided by the invention has the advantages as follows: the control performance is significantly improved; on one hand, the gravity center of a robot system can be controllably changed, the rotational inertia of the overall system can be adjusted, the torque can be reduced, and the working intensity of the driver is reduced; on the other hand, the posture of a robot can be controlled more precisely so as to improve the operating performance of the robot.
