In todays aging society, many people require mobility assistance, that can be provided by robotized assistive wheelchairs with a certain degree of autonomy when manual control is unfeasible due to disability. Robot wheelchairs, though, are not supposed to be completely in control because lack of human intervention may lead to loss of residual capabilities(More)
OBJECTIVE Mobility is of key importance for autonomous living. Persons with severe disabilities may be assisted by robotic wheelchairs when manual control is not possible. However, these persons should contribute to control as much as they can to avoid loss of residual skills and frustration. Traditionally, wheelchair shared control approaches either give(More)
This work presents a new approach to shared control driving a robotic wheelchair for persons with disabilities. The proposal is based on weighting the robot and human commands by their respective efficiencies to obtain an emergent command in a reactive way. It was tested with a robotized Meyra wheelchair at Fondazione Santa Lucia (FSL) in Rome with(More)
This work presents a new approach to shared control to assist wheelchair driving. Rather than swapping control from human to robot either by request or on a need basis, the system estimates how much help is needed in a reactive fashion and continuously produces an emergent motory command in combination with human input. To provide time stability and(More)
This work presents a new approach to proactive collaborative wheelchair control. The system is based on estimating how much help the person needs at each situation and providing just the correct amount. This is achieved by combining robot and human control commands in a reactive fashion after weighting them by their respective local efficiency. Thus, the(More)
This paper addresses a new collaborative control method for robotic wheelchairs. The original method was specifically designed for disabled people who are unable to drive a robotic wheelchair on their own. Its main novelty was that the wheelchair just provided the amount of help needed at each moment, to avoid loss of residual abilities. This wheelchair was(More)
Mobility assistance is of key importance for people with disabilities to remain autonomous in their preferred environments. In severe cases, assistance can be provided by robotized wheelchairs that can perform complex maneuvers and/or correct the user’s commands. User’s acceptance is of key importance, as some users do not like their commands to be(More)
OBJECTIVE Testing is a key stage in system development, particularly in systems such as a wheelchair, in which the final user is typically a disabled person. These systems have stringent safety requirements, requiring major testing with many different individuals. The best would be to have the wheelchair tested by many different end users, as each(More)
