Eye-tracking systems are playing an increasingly important role in assistive robotics as hand-free interaction interfaces for motor impaired people, but no noticeable applications have been developed so far for enhancing the robotic assisted training in functional rehabilitation. In this paper we propose a new gaze-based control to provide active guidance to the upper limb movement, through a robotic exoskeleton, in the functional rehabilitation of pick and place tasks. Experimental results on healthy subjects demonstrate the feasibility of the proposed approach and the breakthrough that the system introduces in the field of eye-based rehabilitation systems.

In recent years, robot-assisted rehabilitation systems have been an active research area that can quantitatively monitor and adapt to patient progress, and ensure consistency during rehabilitation. In this work, an exoskeleton type robot-assisted rehabilitation system called RehabRoby is developed. A control architecture, which contains a high level controller and a low level controller, is designed for RehabRoby. Proprioceptive sense of healthy subjects has been evaluated during the execution of a task with RehabRoby. Additionally, usability of RehabRoby has been evaluated using a questionnaire.

This paper presents a virtual reality-enhanced hand rehabilitation support system with a symmetric master-slave motion assistant for independent rehabilitation therapies. This system consists of a hand exoskeleton device and a lateral symmetric master-slave motion assistant system joined with a virtual reality (VR) environment. Since most disabilities caused by cerebral vascular accidents or bone fractures are hemiplegic, we adopted a symmetric master-slave motion assistant system in which the impaired hand is driven by the healthy hand on the opposite side. Furthermore, a VR environment displaying an enjoyable exercise was introduced. To verify the effectiveness of this system, a clinical trial was executed using one subject.

Exoskeletal devices can provide assistance and supplement to the biological musculoskeletal members. We present a wearable robotic exoskeleton conceived as an improved lower leg orthosis for compensation of human knee and ankle joints disorders provoked by muscle weaknesses during walking, introducing novel biomechanical and user acceptance aspects and daily performance monitoring functionalities.

This paper details the development of a virtual simulation tool for serial manipulators in the Python language (PyMani). PyMani uses a modular design to increase the ease of learning and future development. It was used to test a design for an upper-limb assistive exoskeleton robot with seven degrees of freedom (DoF). Future work will focus on creating additional features, the code is open source and available at sourceforge
