The outcome is a modular robotic arm with six degrees of freedom. The work area can be changed depending on change the length of the individual arms. In the design robotic arm was used three sizes of board modules DSM 110, DSM 70 and DSM 50. The proposed modular robotic arm can be used as an action extension for service robots or as an auxiliary arm of the wheelchair. http://pubs.sciepub.com/ajme/3/6/26/ajme-3-6-26.pdf DSM modules robotic arm kinematic structure DOF
