A fast humanoid robot arm for boxing based on servo motors

Abstract

The sport of boxing has been gradually accepted by the public as a kind of fitness excise. A humanoid robot arm is necessary for this sport since it can reduce the tedious training work of coaching and increase the fun of this exercise. A 4-degree of freedom (DOF) robotic arm was designed by analyzing the basic gestures of boxing, and the servo motor was employed to support the arm’s fast movement. The results show that the robotic arm can fulfill the basic gestures of jab, hook, and swing correctly and the arm joints with servo motor are faster than with stepper motor.
