Abstract:
1. A laminated-type multi-joint portion drive mechanism comprising: a pneumatic drive source for providing pneumatic pressure; a bone member having at least two elastically-deformable elastic deformation portions; a laminated-type pneumatic tube member fixed on said bone member, said laminated-type pneumatic tube member having line-tubes separately connected to said pneumatic drive source; and a planar-type joint-portion flexural deformation member fixed on said laminated-type pneumatic tube member, said planar-type joint-portion flexural deformation member having joint portions and pneumatic operation chambers at said joint portions, separately and respectively, with said joint portions being aligned with said at least two elastic deformation portions, respectively, and said pneumatic operation chambers being separately connected to said line-tubes, respectively, such that when pneumatic pressure is applied to one of said pneumatic operation chambers, a corresponding one of said joint portions is deformed.
