A controller that converts the output of the algorithm into a motor command corresponding to the intention of the user is being developed. The module will make use of a local control loop, so that it can be adjusted when the intended movement differs from the actual movement.

Research focus will be on how fast new intended movements can be transmitted, how fast the user adapts its muscle tension and how precise the control should follow the intended change. By using a new concept of interaction control strategies, “intended behaviour” instead of “intended movement” will be used for the control by, for example, simultaneously regulating stiffness of the prosthetic fingers while the hand is closing.

The new concept will be investigated, subsequently implemented and evaluated in a simulation environment, and finally it will be integrated with the prosthetic hand. It is pursued that the design of the prosthesis is as light as possible.

Results:

• Interactive control algorithm that translates measured muscle contraction into a motor command of the actuator
• Simulation model of the control algorithm
• Implementation of the control algorithm in the hardware setup
• Mechanical analysis, design and implementation of the arm prosthesis
• Report on testing the functioning of the combination of hand and control
