Abstract
We are making research on a kicking mechanism that can kick a ball like a professional soccer player. We measured the human kicking motion for the purpose of searching optimal control algorithm of the kicking mechanism that is designed in parallel with this measurement. We analyzed several human kicks with/without approach steps of the free kick using a high speed camera, goniometers, and electro myoelectric signals (EMG). We confirmed from the experiments that the legs motion is like a whip in order to use kinetic energy effectively as literature says. The result of the analysis is feedbacked to the control of the current version of the kicking mechanism as well as the mechanical design of the next version.
