Shoulder complex linkage mechanism for humanlike musculoskeletal robot arms.

Bioinspiration & biomimetics Nov 5, 2015
The shoulder complex in the human body consists of the scapula, clavicle, humerus, and thorax and bears the load imposed by arm movements while at the same time realizing a wide range of motions. To mimic and exploit its role, several musculoskeletal...
