Robotic rehabilitation devices based on Brain-Computer Interfaces: wheelchair and teleoperated robot
نویسندگان
چکیده
This paper describes two innovative brain-actuated applications for rehabilitation developed in the University of Zaragoza: the first one is a brainactuated wheelchair with automated navigation, and the second one is a brain-actuated robot to carry out teleoperation tasks between remote places. Briefly, the subject faces a real-time virtual reconstruction of the scenario (wheelchair) or video captured by a camera merged with augmented reality items (robot) and concentrates on the area of the space to reach. First, a visual stimulation process elicits the neurological phenomenon (evoked P300 response), the EEG signal processing detects the target, and given then to the autonomous navigation system that drives the device to the desired place while avoiding collisions with every obstacle detected. These systems have been validated with ten healthy users (five for each application). The overall result is that all the users successfully used the device with relative ease and adaptability.

A 9-DoF Wheelchair-Mounted Robotic Arm System: Design, Control, Brain-Computer Interfacing, and Testing
A wheelchair-mounted robotic arm (WMRA) system was designed and built to meet the needs of mobility-impaired persons with limitations of upper extremities, and to exceed the capabilities of current devices of this type. The control of this 9-DoF system expands on the conventional control methods and combines the 7-DoF robotic arm control with the 2-DoF power wheelchair control. The 3-degrees of...

This paper describes our ongoing project about a new wheelchair-based rehabilitation robotic system for the disabled, called KARES 11 (KAIST Rehabilitation Engineering Service System Io. We shall concentrate on the issues of design and visual servoing of the robotic arm with three human-robot interaction subsystems: an eyemouse, an EMG interface, and a haptic suit interface. First, the specific...
متن کاملA review on brain computer interfaces: contemporary achievements and future goals towards movement restoration
Restoration of motor functions of patients with loss of mobility constitutes a yet unsolved medical problem, but also one of the most prominent research areas of neurosciences. Among suggested solutions, Brain Computer Interfaces have received much attention. BCI systems use electric, magnetic or metabolic brain signals to allow for control of external devices, such as wheelchairs, computers or...
متن کاملHuman-Computer Interaction Issues in Brain- Computer Interface and Virtual Reality
Recently, there has been increasing interest in using BCI in 3D virtual environments. There are several reasons for using a brain-computer interface in virtual reality (VR); some of these are the same reasons for using VR in general: rehearsal of scenarios that are too dangerous in the real world (e.g., controlling a wheelchair); prototyping devices (e.g., robotic hand); prototyping new control...
متن کاملA self-paced motor imagery based brain-computer interface for robotic wheelchair control.
This paper presents a simple self-paced motor imagery based brain-computer interface (BCI) to control a robotic wheelchair. An innovative control protocol is proposed to enable a 2-class self-paced BCI for wheelchair control, in which the user makes path planning and fully controls the wheelchair except for the automatic obstacle avoidance based on a laser range finder when necessary. In order ...
