• Traditional approach– Robots and grippers with limited or
no sensors (vision, touch)– Mechanical repeatability– Adapt the environment / process
• System broken in pieces (arm, hand, vision)
• Gripper choice left aside while planning project

Southampton Hand Assessment Procedure (SHAP)•Measure performance of upper limb prostheses•Also applied to musculoskeletal and unimpaired participants•26 tasks
– 8 abstract objects– 14 activities of daily living
•Measured success and speed used to calculate performance
