Problem to be solved: to provide a mechanism for operating a robot or toy joint by force and repulsive force by an electronically controlled electromagnet and a permanent magnet.The parts of the joint are moved by the force of the magnetic attraction which is repulsive by switching the S pole and the N pole of the permanent magnet (a) mounted on each part of the joint and the electronically controlled electromagnet (b).Diagram【課題】電子制御された電磁石と永久磁石による磁力の引き寄せと反発の力でロボットや玩具の関節を動作させる機構を提供する。【解決手段】関節の各パーツに取り付けられた永久磁石(A)と電子制御された電磁石(B)のS極、N極の切り替えで反発、引き寄せの磁力の力で関節パーツを可動させる。【選択図】図2
