ABSTRACT:
A robot finger structure includes a first joint member, a second joint member, a fluid pipe, and a third joint. The first joint member has a fluid path. The second joint member has a fluid path and is pivotally supported by the first joint member while the fluid path of the second joint member communicates with the fluid path of the first joint member, pivotal movement of the second joint member being stopped upon abutment with the first joint member. The fluid pipe supplies a fluid to the fluid path of the first joint member. The third joint member is pivotally supported by the second joint member, is pivoted upon reception of a pressure of the fluid supplied to the first and second joint members through the fluid paths, and is brought into contact with the second joint member.
