Force Control of Musculoskeletal Manipulator Driven By Spiral Motors

Abstract

AbstractThis paper presents force control of musculoskeletal manipulator driven by spiral motors. The kinematic and dynamic properties are shown to address the presence of ennvironmental contact with the manipulator. From this contact, the force control schemes were explored, by comparing between monoarticular-only structure and biarticular structure manipulator. Force control schemes were divided into independent muscle control, end effector step force command, and muscular viscoelasticity control. The results show advantages of biarticular actuation compared to monoarticular-only actuation in the feasibility of magnetic levitation (gap) control alongside force control.U ovome radu predstavljeno je upravljanje silom mišićno-koštanog manipulatora pogonjenog spiralnim motorom. Kinematička i dinamička svojstva prikazuju prisutnost kontakta manipulatora s okolinom. Na temelju kontakta istraženo je upravljanje silom usporedbom jednozglobne i dvozglobne strukture manipulatora. Upravljanje silom podijeljeno je u neovisno upravljanje mišićima, upravljanje alatom manipulatora (eng. end effector) i upravljanje mišićnom viskoelastičnosti. Rezultati pokazuju prednost dvozglobne strukture u odnosu na jednozglobnu u smislu izvedivosti upravljanja magnetskom levitacijom pored upravljanja silom.Key words: biarticular muscleforce controlclosed kinematicparallel manipulatormuscular viscoelasticityKljučne riječi: dvozglobna struktura mišićaupravljanje silomzatvorena kinematikaparalelni manipulatormišićna viskoelastičnost Additional informationNotes on contributorsAhmad Zaki bin Hj ShukorAhmad Zaki Shukor received the B.E. from Universiti Teknologi Malaysia in 2002 and M.E. from University of South Australia in 2004.
