    For central nervous system (CNS) impaired patients, e.g. after stroke, the achievement of an independent, stable gait function and endurance in walking is essential for independent mobility in daily life. Modern concepts of rehabilitation favor a task specific repetitive training, that facilitates natural motion and muscle activation patterns, i.e. in addition to commonly practiced floor walking other gait motions of daily living (ADL), such as stair climbing, should be trained. In gait rehabilitation of severely affected non-ambulatory patients, a guided training must be applied as no or only little voluntary motor control is left in the affected side. The rehabilitation robot HapticWalker is the first device that allows for robot assisted guided training of arbitrary foot trajectories, e.g. also stair climbing. The goal of this study was to assess the effect of guided training in stair climbing condition on the HapticWalker on the movement and muscle activation patterns of stroke patients. Generally rhythmic and phasic muscle activation patterns were observed, which is an important factor in gait rehabilitation. The training of stair climbing condition on the HapticWalker also facilitated body weight shift in all patients and proper activation of weight bearing muscles. The HapticWalker currently lacks a lateral hip guidance facility, hence individual differences in the ability of controlling hip movement and body weight shift depending on the level of gait ability were observed.

    Operational control for robot system integration into CIM - results and benefits
    ( 1990)
    Bernhardt, R.
    The aim of the article is to present a quantification of results and benefits reached in the ESPRIT 623 project: "Operational Control of Robot System Inegration into CIM". Thereby following areas are addressed: - delivery of product, - acquisition of projects, - standardization activities, - technology transfer, and - education. The quantification is based on an inquiery done among the project partners.

    Inspection of off-shore structures
    ( 1990)
    Schreck, G.
    For the inspection of underwater structures a remote handling system is being developed. The main components are a remote-controlled submersible transporting a robot and several tools. The presentation gives an overiew, how to use off-line programming techniques as well as for the vehicle programming as for the task and task execution planning for the robot.
