- the gist of the present invention is not necessarily limited to products called “robots”. In other words, if a mechanical device performs a motion that resembles human motion using an electric or magnetic action, the same applies to a product belonging to another industrial field such as a toy.
- the present invention can be applied to In short, the present invention has been disclosed by way of example, and the contents described in this specification should not be limited. In order to determine the gist of the present invention, the claims described at the beginning should be considered.
- the number of actuators used for the multi-joint bending drive can be reduced, so that it is possible to produce a small and inexpensive product. Therefore, it is possible to contribute to a reduction in the cost and size of the device having such a multi-joint bending mechanism.
