Abstract

PROBLEM TO BE SOLVED: To provide a mechanism for operating a joint of a robot or toy with attraction force and repelling force of magnetic force of an electric magnet that is electronically controlled and a permanent magnet.SOLUTION: A joint parts are moved with repelling and attraction of magnetic force by switching between S pole and N pole of a permanent magnet (A) attached to each part of a joint and an electric magnet (B) that is electronically controlled.SELECTED DRAWING: Figure 2

Description

The present invention is designed to drive each joint of a robot simply, lightly, silently and simply by the force of magnetic force without using heavy starting sound parts such as motors and gears used for joint driving in recent robots. Invention.

The joint parts are moved by the magnetic force of repulsion and repulsion by switching between the S poles and N poles of the permanent magnets and electronically controlled electromagnets attached to each part of the joint.

It is thought that it is possible to express the strength and smoothness of movement by individual control of each electromagnet.

By putting artificial cartilage (cushion material) in the gaps between each joint part, it is possible to prevent damage when the electromagnet and permanent magnet come into contact, and to express a silent effect, assisting the repulsive force of the magnetic force, and smooth movement of the joint.

Since the present invention is simple and can be manufactured at low cost, it is expected to be used as a toy at first, but humanoid and animal type robots can be created to develop motion programs such as teaching materials for robot operation programs at low cost. It is considered.
Other than this, I thought of this invention because it can be manufactured at low power, light weight and low cost, such as developing a prosthetic leg for people who have lost some of their limbs.

A mechanism that moves the joints of robots and toys with the force of repulsion and repulsion by electronically controlled electromagnets and permanent magnets.

The joint part can be moved by the force of the magnetic force of repulsion and repulsion by switching the S pole and N pole of the permanent magnet (A) attached to each part of the joint and the electromagnet (B) controlled electronically.

It is thought that it is possible to express the strength and smoothness of joint bending and stretching by individual control of each electromagnet.

Artificial cartilage (cushion material) (C) is put in the gap between each joint part to prevent damage when the electromagnet (B) and permanent magnet (A) are in contact with each other, assisting the silent effect and repulsive force of the magnetic force. I think that it can express the joint movement.

The present invention is simple and can be manufactured at low cost, so it is expected to be used as a toy at first, but it can be developed at low cost such as teaching materials for motion program robots that create human-type and animal-type robots and develop motion programs I think.
Other than this, I thought of this invention because I thought it would be possible to manufacture it at low power, light weight, and low cost, such as developing a prosthetic leg for people who lost part of their limbs.

Claims (2)

A mechanism to move the joint by the repulsion and pulling force of the permanent magnet (A) attached to each part of the joint and the electromagnet (B) individually electronically controlled Artificial cartilage (C) that compensates for the repulsion of magnetic force between the electromagnet (B) and permanent magnet (A) of the joint and produces a silent effect.
