This research focuses on implementing Machine Learning Impedance Control for robot arms to ensure both effective and safe interaction within unknown environments. The designed Machine Learning system comprises two key steps. Firstly, a Neural Network Classifier framework categorizes attributes by assigning labels to various impedance behaviors. Secondly, employing a regularization technique, the system determines the appropriate impedance behavior as a command signal for the internal control loop. Utilizing a backstepping-based algorithm alongside Taylor’s parameter adaptation within the control loop facilitates achieving effective interaction.

摘要

This research focuses on implementing Machine Learning Impedance Control for robot arms to ensure both effective and safe interaction within unknown environments. The designed Machine Learning system comprises two key steps. Firstly, a Neural Network Classifier framework categorizes attributes by assigning labels to various impedance behaviors. Secondly, employing a regularization technique, the system determines the appropriate impedance behavior as a command signal for the internal control loop. Utilizing a backstepping-based algorithm alongside Taylor’s parameter adaptation within the control loop facilitates achieving effective interaction. To validate the efficacy of this control approach, the proposed method undergoes testing and simulation on a two-link robot manipulator across varying environmental stiffness levels.
