Abstract

In order to reduce the burden of caregivers facing an increased demand for care, particularly for the elderly, we developed a system whereby multiple robotic wheelchairs can automatically move alongside a companion. This enables a small number of people to assist a substantially larger number of wheelchair users effectively. This system utilizes an environmental map and an estimation of position to accurately identify the positional relations among the caregiver (or a companion) and each wheelchair. The wheelchairs are consequently able to follow along even if the caregiver cannot be directly recognized. Moreover, the system is able to establish and maintain appropriate positional relations.
