Summary:
Thi This st study udy co comp mpares th ares three ree di diffe ffere rent c nt cont ontrol rol al algor gorit ithms f s for a muscle muscle-like -act actuate uated ar d arm de m develo veloped ped to replicate plicate mo motio tion in t two d o degree ees-o s-of-fre -freed edom (df) f): el : elbo bow fle w flexion/e on/exte tensio nsion (f n f/e) a /and f nd forear rearm pr pronat onation/supinati ation ( on p/s). ). Electr Electromy myogra ogram (EMG) i is empl ployed to help ed det determine t e the c e cont ontro rol si signal gnal used ed to act actuate t uate the mu muscle c scle cylinders. linders. Th Three d ree diffe fferent rent ty types o pes of cont control strate rol strategie gies were atte attempte mpted.
