Assistive robotics are playing a vital role in advancing the quality of life for disable people. There exist wide range of systems that can control and guide autonomous mobile robots. The objective of the control system is to guide an autonomous mobile robot using the movement of eyes by means of EOG signal. The EOG signal is acquired using Ag/AgCl electrodes and this signal is processed by a m...

In this paper, we explore the use of synthesized landmark maps for absolute localization of a smart wheelchair system outdoors. In this paradigm, threedimensional map data are acquired by an automobile equipped with high precision inertial/GPS systems, in conjunction with light detection and ranging (LIDAR) systems, whose range measurements are subsequently registered to a global coordinate fra...

This paper presents a new method to control and guide mobile robots. In this case, to send different commands we have used electrooculography (EOG) techniques, so that, control is made by means of the ocular position (eye displacement into its orbit). A inverse eye model is developed based in electrooculography and therefore the saccadic eye movements can be detected and know where user is look...

abstract This chapter introduces the main trends in the design of interfaces for smart wheelchairs. It stresses the importance of taking into account their similarity with autonomous mobile robots and the restrictions posed by the special characteristics of the users (people with severe motor and speech restrictions) and the task (indoor assisted navigation). With this background, the main feat...

MULTIMODAL INTERFACE FOR DISABLED PERSONS S.A. Chhabria and R.V. Dharaskar Department of Computer Science and Engineering, G.H. Raisoni College of Engineering, Nagpur. E-mail: [email protected] Assistive robots have the potential to provide disabled people with effective ways to alleviate the impact of their limitations, by compensating for their specific impairments. In particular, r...

Autonomous Robotic Wheelchairs in Europe by Spyros G. Tzafestas (National Technical University of Athens) Autonomous robotic wheelchairs (ARWs) represent an important class of autonomous mobile robots (AMRs) [1-3] that is receiving increasing attention all over the world. This is due to the strong need of easier wheelchair mobility throughout a longer average life of the handicapped. In the Eur...

A spatial parallel mechanism namely 3-RRS mechanism has been assigned to be attached to the seat of a standard electric wheelchair to prevent the turning over of the handicapped sitting on the wheelchair. The system of the wheelchair and the mechanism is a self-balancing robotic wheelchair and has coped with several road conditions. A stability control system calculates the proper moments on th...

Objectives: Extensive use of wheelchair increases caregiver dependency, risk of bedsores, risk of injury during transfer, and so on, and it effectively decreases quality of life, safety, and comfort of the people with disability. Therefore, improving the design of wheelchairs is highly essential in promoting the quality of life and level of participation among people with disability. The design...

This paper presents RouteLoc, a new approach for the absolute self-localization of mobile robots in structured large-scale environments. As experimental platform, the Bremen Autonmous Wheelchair “Rolland” is used on a 2,176m long journey across the campus of the Universität Bremen. RouteLoc poses only very low requirements with regard to sensor input, resources (memory, computing time), and a-p...

This chapter describes an approach of secure navigation systems for wheelchairs and mobile robots platforms, using RF signal triangulation and Extended Kalman Filter in conjunction with Genetic Algorithm for indoor trajectory optimization. Initial systems are implemented and tested at virtual environment with conception of supervision and control systems for mobile robots, which are capable of ...
