This thesis presents the development of a distributed control system for the DynamicArm, a myoelectrically controlled arm prosthesis by Ottobock. This is to clarify whether the control of the prosthetic arm can be realized by means of a distributed system based on the AXON-Bus®. On this basis, the compatibility with other AXON-Bus® based products of Ottobock can be ensured. Furthermore, the possibility is checked whether the automatic transmission adjustment algorithm, based on a measurement of the motor current, for the infinitely variable frictiongear of the original DynamicArm, can be replaced by an alternative concept. This should bypass the weak points of the original algorithm. In order to find answers to these questions, a prototype, containing such a distributed system, arises in the course of this work. This includes building the prototype based on the mechanical components of the original DynamicArm, replacing the original electronics with AXON-Bus® compatible electronics, and developing the software to control the arm functions. Furthermore, a transmission adjustment algorithm is designed and implemented based on the measurement of the transmission value of the friction gear. To test the resulting prototype, a series of experiments is carried out. The behavior of the newly developed adjustment algorithm is examined by means of lifting tests at different loads. In addition, comparative measurements are made, in terms of energy consumption per stroke performed, between the prototype and an original DynamicArm. Thus, it is shown that the control is feasible by means of a distributed system and that the newly developed adjustment algorithm has the desired properties.
