Sijs, J. (author), Liefhebber, F. (author), Römer, G.W.R.B.E. (author), TNO Industrie en Techniek (author)The ARM is a 6 DOF robotic manipulator used by disabled people with a severe handicap at the upper extremities The present ARM is position and velocity controlled. The desired position of the robot is given by the user. However, in constraint scenario's, manipulation becomes too difficult and an assistant-controller is wanted. This assistant is...conference paper 2007

Liefhebber, F. (author), Sijs, J. (author), TNO Industrie en Techniek (author)The rehabilitation robot Manus is an assistive device for severely motor handicapped users. The executing of all day living tasks with the Manus, can be very complex and a vision-based controller can simplify this. The lack of existing vision-based controlled systems, is the poor reliability of the computer vision in unstructured environments....conference paper 2007

Driessen, B.J.F. (author), Liefhebber, F. (author), ten Kate, T.K. (author), van Woerden, J.A. (author), TNO Industrie en Techniek (author)The Manus manipulator is a wheelchair mounted assistive device for severely motor disabled persons. It is a six degrees of freedom rehabilitation robot (excluding external lift and gripper) of which the control can be improved through the introduction of sensors, especially for users with very limited rest functionality. The approach presented...conference paper 2005

Tijsma, H.A. (author), Liefhebber, F. (author), Herder, J.L. (author)New user interface features and a new user interface for the MANUS robot arm, were designed in order to reduce the high cognitive and physical load that users experience when controlling the MANUS. These interface features, and the new interface, were evaluated for their performance. The following results were obtained. A new method of switching...conference paper 2005

Tijsma, H.A. (author), Liefhebber, F. (author), Herder, J.L. (author)Users of the MANUS robot arm experience a high cognitive and physical load when performing activities of daily living with the arm. These high loads originate from user interface problems and limitations. To reduce these high loads the user interface of the MANUS needs to be improved. Because large differences exist between the residual...conference paper 2005
