Image humanoid built of joint modules modified with the help of dimension mechanics. Compact and powerful joint modules consisting of encoders, motor, eccentric gear and worm gear. Human try to self-actualize in automation and robotic. The mechanics of a robotic hand presented here gets us closer to that. It is shown that skilled application of innovative gearing technologies can bring a robotic hand and even a complete humanoid very close to a human’s motivity, statics and dynamic. For this the basic element a robot consists of, the joint module, is significantly improved mechanically! Hence a complete humanoid can be built with this basic element applying skilled variance and dimension mechanics.
