Abstract

The invention provides a robot dragging demonstration method and device, electronic equipment and a storage medium. The robot dragging demonstration method comprises the steps of: obtaining initial position parameters, initial speed parameters and initial acceleration parameters of a tail end of a robot main body; obtaining effective constant force parameters of the robot main body to a base in each of multiple continuous periods; inputting the initial position parameters, the initial speed parameters, the initial acceleration parameters and the effective constraint force parameters detected in each period into a mass-spring-damper system model to respectively calculate actual position parameters, actual acceleration parameters and actual speed parameters of ending points in correspondingperiods; and controlling corresponding joints of the robot to move according to the actual position parameters, the actual acceleration parameters and the actual speed parameters to finish the dragging demonstration in the corresponding periods. The robot dragging demonstration method can prevent the problem of errors in kinetic parameter identification in kinetic compensation methods.

Description

technical field [0001] The present application relates to the field of robot technology, in particular, to a method, device, electronic device and storage medium for dragging and teaching a robot. Background technique [0002] At present, there are two mainstream robot drag teaching methods: drag teaching based on the terminal six-dimensional force sensor and drag teaching based on robot dynamics compensation. The drag teaching method based on the six-dimensional force sensor at the end is realized through admittance control. The force sensor acquires external force and controls the speed or position of the end of the robot through the admittance. The drag teaching method based on robot dynamics compensation is to identify the dynamic parameters of the robot, including the mass, center of mass, friction and motor rotor inertia of each joint of the robot, calculate the joint torque according to the dynamic equation and compensate it to the corresponding joint , to realize dr...
