This paper describes a hands-off socially assistive therapist robot that monitors, assists, encourages, and socially interacts with post-stroke users engaged in rehabilitation exercises. We investigate the role of the robot's personality in the hands-off therapy process, focusing on the relationship between the level of extroversionintroversion of the robot and the user. We also demonstrate a b...

This paper presents several novel interactive human-robot systems which were recently developed at IPK. These systems were designed for direct physical interaction between humans and robots. The principal structures and functions of the following robotic systems are briefly presented: ROBOPED, an advanced parallel robot for orthopedic diagnostics and rehabilitation, STRING-MAN, a wire robot for...

This paper presents a new intelligent method to control rehabilitation robots by mainly considering reactions of patient instead of doing a repetitive preprogrammed movement. It generates a general reference trajectory based on different reactions of patient during therapy. Three main reactions has been identified and included in reference trajectory: small variations, force shocks in a single ...

This report describes the design of an autonomous mobile assistant robot, which helps post-stroke patients during their rehabilitation by providing encouragement, reminders, and support. Studies show that the prevalence of stroke will increase in the future and since post-stroke patients need supervision by trained professionals, the rehabilitation needs to be made more efficient. Toward this g...

Robot-assisted rehabilitation, which can provide repetitive, intensive and high-precision physics training, has a positive influence on motor function recovery of stroke patients. Current robots need to be more intelligent reliable in clinical practice. Machine learning algorithms (MLAs) are able learn from data predict future unknown conditions, is benefit improve the effectiveness robot-assis...

This paper investigates and presents a cable-driven robot to lower limb rehabilitation use in sagittal plane. The presented rehabilitation robot is used for a trajectory tracking in joint space. The paper covers kinematic and dynamic analysis, which reveals the tensionability of the used cables as being the actuating source to provide a rehabilitation exercises of the human leg. The desired tra...

We present a dedicated video-based monitoring system for quantification of patient’s attention to visual feedback during robot assisted gait rehabilitation. Two different approaches for eye gaze and head pose tracking are tested and compared. Several metrics for assessment of patient’s attention are also presented. Experimental results with healthy volunteers demonstrate that unobtrusive video-...

In this review, we give a brief outline of robot-mediated gait training for stroke patients, as an important emerging field in rehabilitation. Technological innovations are allowing rehabilitation to move toward more integrated processes, with improved efficiency and less long-term impairments. In particular, robot-mediated neurorehabilitation is a rapidly advancing field, which uses robotic sy...
