Embodiment Construction
[0036] The technical solution of the present invention will be further introduced below in combination with specific embodiments.
[0037] This specific embodiment discloses a speed control method of a high-precision traction teaching robot based on an impedance model, including the following steps:
[0038] S1: The robot controller collects the information of the six-dimensional force sensor, first filters the collected information, then performs gravity compensation, and finally obtains the deviation data from the expected force or expected torque value;
[0039] S2: Transform the force deviation data or torque value deviation data into the speed at which the end of the robot moves in Cartesian space and the angular velocity around the axis according to the impedance model;
[0040] S3: Smoothly interpolate the motion according to the deformed S-shaped speed control curve to obtain the corresponding position function, speed function and acceleration function;
[0041] S4: A...
