The device comprises a joint shaft bracket, a joint shaft, a joint shaft fixing pin, a joint torsion spring, a joint bearing, a joint bearing support, a motor mounting rack, a motor, an electromagnetic clutch, an electromagnetic clutch mounting rack, a worm small support bearing, a worm-wheel shaft, a worm gear support large bearing, a worm gear support large bearing end cover, a worm shaft, a worm support large bearing, a worm gear mounting rack, a worm gear support small bearing, a synchronous toothed belt, a synchronous pulley, an electromagnetic clutch bracket, a tension wheel mounting rack, a tension wheel, a worm support large bearing end cover, a worm fixing pin and a worm. The modular driving device is suitable for driving the joints of the hopping robot, and has the characteristics of low power demand for the motor, and high hopping performance; and the motor performance is played fully.

Description

technical field [0001] The invention relates to a modular driving device for elastic joints of a small multi-joint jumping robot, which is suitable for driving the joints of a small jumping robot. Background technique [0002] The current small multi-joint jumping robot uses a motor to drive the joint shaft to rotate, so as to realize the overall jumping motion of the robot. In the document "Back Handspring Robot-Target Dynamics-Based Control", Sang-Ho Hyon discusses a humanoid jumping robot, which has 3 joints in total, and uses 3 motors to control the motion of the joints independently, using motors, v-belts, and ordinary joint axes. The transmission and jumping motion of the whole machine have higher requirements on the power of the motor. [0003] The suddenness and explosiveness of the jumping motion requires high power of the drive motor, and at the same time, the characteristics of the jumping motion require the light weight of the whole machine. In this way, there ...
