| Outline of Final Research Achievements |
In this research, J-type omnidirectional driving gear was produced as a mechanism for motions of translation and revolution of the fingernail mechanism on the fingers of the robotic hand. As a result, motions of translation and revolution of the fingernail mechanism with only one gear was realized. Its wider motion range was also achieved.
A spherical omnidirectional driving gear was newly developed as a mechanism to realize a finger joint that turns in the forward and backward direction, and realized with only one spherical gear with two orthogonal rotating joints at one point, realizing a wide movable range. A finger mechanism for attaching a movable claw mechanism to the tip was manufactured using three spherical omnidirectional drive gears and experiments were carried out.
For the fingertip nail mechanism, a mechanism using a shape memory gel was manufactured so that the fingertip was more likely to adapt to the shape of the object or obstacle to be gripped.
