Abstract

The invention provides a magneto-rheological smooth controller for a robot joint. The magneto-rheological smooth controller for the robot joint comprises a closed cavity, a first gear, a second gear and an electromagnetic coil; magneto-rheological liquid fills in the closed cavity; the first gear and the second gear are arranged in the closed cavity, wherein the first gear engages with the second gear; a first gear shaft of the first gear and a second gear of the second gear both extend out from the closed cavity; the electromagnetic coil for changing the magnetic field intensity in the closed cavity is mounted at the side edge of the closed cavity; the first gear shaft or the second gear shaft is connected with a driving mechanism which drives the first gear or the second gear to rotate. The magneto-rheological smooth controller for the robot joint integrates rigid, passive smooth, active smooth and rigid driving and smooth controlling, and is self-adaptive to the robot joint.

Description

technical field [0001] The invention relates to the field of robots, in particular to a robot joint. Background technique [0002] At present, the driving principles of the rotary joints of the robot mainly include two types. One type is driven by a motor and transmitted through gears, ropes, pulleys, etc. This type of joint has good rigidity and passive flexibility, but does not have active flexibility; the other type is driven by fluid, and this type of joint has good active flexibility. Flexible, but not rigid enough. However, when a robot, especially a robot dexterous hand, needs to maintain sufficient gripping force according to the different grasping and gripping objects, and adjust the gripping force in real time as needed; on the other hand, it needs to have Better active flexibility to ensure its intrinsic safety, but also to ensure the safety and comfort of the object being grasped and held. This requires that the robot's humanoid dexterous hand needs to have th...
