Obstacle Avoidance Wheelchair System
نویسندگان
چکیده
We present a collision avoidance system for powered wheelchairs used by people with cognitive disabilities. Such systems increase mobility and feelings of independence, thereby enabling reversal of some symptoms of depression and cognitive impairment and improvement of quality of life. We use a novel 3D sensor developed by Canesta Inc. that allows the wheelchair to “see” obstacles, avoid collisions, and suggest alternatives to users. The Canesta sensors are ideal, as they combine accuracy with efficiency in the distance range necessary for collision avoidance.

Service robotics is a new, emerging domain in robotics, characterised by enthusiasm, diverseness, and emerging industry. The paper presents modular and interacting obstacle avoidance, and navigation subsystems. The obstacle avoidance system is older, so there are practical experiences of its application to electric wheelchairs, which are explained. Ongoing work with the navigation unit is revie...
متن کاملNavChair: An Example of a Shared-Control System for Assistive Technologies
The NavChair assistive navigation system was originally conceived as an application of mobile robot obstacle avoidance to a power wheelchair. In this system, the user shares wheelchair control with obstacle avoidance and other navigation components. The philosophy of shared control has important implications for the design of these components. This paper discusses the development of navigation ...

This paper describes new results with a Reactive Shared-Control system that enables a semi-autonomous navigation of a wheelchair in unknown and dynamic environments. The purpose of the reactive shared controller is to assist wheelchair users providing an easier and safer navigation. It is designed as a fuzzy-logic controller and follows a behaviour-based architecture. The implemented behaviours...

In this paper, an assist method for human operation of electric-powered wheelchairs is studied. The purpose of this research is to make powered wheelchairs intelligent and to realize a mobility aid for people, who find it difficult or impossible to drive a conventional wheelchair. On a prototype of our group, a neural network produces an obstacle avoidance function. In this research, by the app...
متن کاملA Behavior Based Fuzzy Control Architecture for Path Tracking and Obstacle Avoidance
This paper presents an improvement to the Reactive Shared-Control System (Pires and Nunes, 2002) in development at the ISR (Institute of Systems and Robotics). A path tracking behaviour is being added in the control architecture in order to increase the navigation autonomy of a powered wheelchair (RobChair). The paper focuses on the implementation of the path-tracking by means of fuzzy logic an...
