    DEVELOPMENT OF MULTI-MODAL CONTROL INTERFACES FOR A SEMI-AUTONOMOUS WHEELCHAIR

    Get PDF
    The purpose of the project is to assist users with different levels of disabilities to control a semi-autonomous wheelchair. A semi-autonomous wheelchair developed by RIVeR Lab is able to perform assistive control to avoid obstacles and cliffs and to follow walls. With a joystick control adapter, the basic joystick of the wheelchair can take commands directly from computers. In addition to joystick mechanical adapter control, human-machine interaction and control methods such as voice and electromyography (EMG) are deployed, with the aim of enabling people with different levels and types of disabilities to control the wheelchair. These non-physical motion based user control interfaces allow people with limited mobility to control the wheelchair with a desired accuracy

    thesisIncreased demand for powered wheelchairs and their inherent mobility limitations have prompted the development of omnidirectional wheelchairs. These wheelchairs provide improved mobility in confined spaces, but can be more difficult to control and impact the ability of the user to embody the wheelchair. We hypothesize that control and embodiment of omnidirectional wheelchairs can be improved by providing intuitive control with three degree of freedom (3-DOF) haptic feedback that directly corresponds to the degrees of freedom of an omnidirectional wheelchair. This thesis introduces a novel 3-DOF Haptic Joystick designed for the purpose of controlling omnidirectional wheelchairs. When coupled with range finders, it is able to provide the user with feedback that improves the operator's awareness of the area surrounding the vehicle and assists the driver in obstacle avoidance. The haptic controller design and a stability analysis of the coupled wheelchair joystick systems are presented. Experimental results from the coupled systems validate the ability of the controller to influence the trajectory of the wheelchair and assist in obstacle avoidance

    Evaluation of Electric Powered Wheelchairs and Exposure to Whole-Body Vibration

    The detrimental results of whole-body vibration (WBV) and their effect on humans in the seated position have been documented. Although wheelchair users are subjected to WBV little research has been conducted to assess these vibrations or attempt to reduce them.Sixteen able bodied subjects tested two powered wheelchairs: a Quickie S-626 and an Invacare 3G Torque SP. Each subject tested all of the configurations of the suspension wheelchairs and solid inserts to represent a non-suspension wheelchair. In each of the configurations of the wheelchairs, the subjects traversed an Activities of Daily Living (ADL) course. Vibrations were collected from a tri-axial accelerometer mounted to a ¼ inch aluminum seat plate during driving over the activities course. Root Mean Square Values and Vibration Dose Values were analyzedStatistical analyses of the RMS and VDV data revealed significant differences between the six different suspensions over each of the obstacles in the activities of daily living course. Post-hoc analyses revealed that for each of the obstacles, significant differences existed between the Invacare suspension and the Invacare solid insert. For the Quickie power wheelchair the solid insert setting was not significantly different from the most-stiff setting for each of the obstacles except the smooth surface. The solid insert setting was significantly different than the lowest and mid stiffness settings for all of the obstacles except the smooth surface and the deck surface.Without significant periods of rest the effects of WBV are cumulative throughout the course of the day, and the longer the exposure time the lower the threshold of non-harmful vibrations. Although most of the suspension systems are capable of reducing the amounts of vibration transmitted to the users the results of the vibration dose values seem to indicate that they may not reduce them enough to reduce probability of injury in powered wheelchair users.Future work should move towards examining these vibrations to evaluate what actual levels of WBV wheelchair users are experiencing over the course of an entire day and examining relationships between suspension and user weight to make data available to clinicians and wheelchair companies for suspension tuning

    Powered Device for Pushing a Manual Wheelchair

    Get PDF
    The goal of this project was to design and prototype a cost-effective, powered, manual wheelchair-pusher that is easy to use, transportable, and satisfies the requirements of institutional and personal use. The device locks around a crossbar underneath the wheelchair and uses a battery-powered motor with a drive wheel and a manually controlled front wheel to steer. Testing confirmed the functionality of the pusher; further improvements to the device are recommended so that it may be used by an institution or individual

    Investigation on electric motor braking control system for electric powered wheelchair

    Get PDF
    In recent years, research on Electric Powered Wheelchair (EPW) has been widely studied due to its high importance of mobility for disabled people. During descent on a slope, the manual braking system is commonly used to control the speed by gripping the brake lever. However, the task becomes difficult if the user is an elderly or paralyzed due to their body’s deficiencies. As a result, the possibilities of collision and injuries to occur are high. In this study, the automatic electric motor braking control that is known as Hill Descent Control (HDC) is proposed to increase the safety of EPW during descending on slopes. Since the electric motor has an advantage which can generate the torque during braking, the plugging braking is integrated with the HDC system to control the speed of the EPW according to the desired speed from the user. The analysis of this study is divided into three phases; investigation of braking performance using electrical braking, development of active braking control system in the embedded system as well as the simulation environment and analysis on active braking control system in experimental and simulation work. From the experimental results, the plugging brake is most suitable to integrate with the active brake control system compared to the regenerative and dynamic brake. In the plugging brake, by changing the plugging voltage from 0.5 V to 4.5 V, a variety of dynamic behaviour effects such as braking distance, tire speed and slip ratio can be achieved. Meanwhile, from the analysis of active braking control system that was integrated with plugging braking, both of the experimental and simulation analysis results show the speed of EPW can be maintained at the desired speed o
