Abstract:
This spherical surface link mechanism comprises a proximal end link hub, a tip link hub, a plurality of links, a plurality of intermediate link hubs, and a shaft member. Each of the plurality of links has a first end link member, a second end link member, and an intermediate link member. The first end link member is connected to the proximal end link hub to be rotatable about a first rotation axis at one end. The second end link member is connected to the tip link hub to be rotatable about a second rotation axis at one end. The intermediate link member is connected to the other end of the first end link member to be rotatable about a third rotation axis at one end and is connected to the other end of the second end link member to be rotatable about a fourth rotation axis at the other end.
