Abstract

With the application of deep learning, prosthetic rehabilitation can be carried out in a manner that not only emulates human manipulation skills and performance, but can also work more efficiently. In this study, we introduced computer vision capability for a rehabilitation robot using a convolutional neural network (CNN). The human skill of scooping was studied by dividing it into four motion primitives or sub-tasks. For each primitive, optimum human posture was identified in terms of muscular effort. Human motion skills were analyzed in terms of physiological parameters, including wrist pronation-supination angle, elbow flexion angle, shoulder rotation/abduction/flexion angles, and hand accelerations by three dimensional musculoskeletal modeling. This analysis identified how humans execute the same activity for eight different materials. Optimum human motion for each material was mapped to a robotic arm with six degrees-of-freedom (DOFs), which was equipped with a camera. The success ratio while examining the scooping motion over all trials was found to be 85%. Consequently, the activity can be performed efficiently based on human intuition in a dynamic environment.
