Abstract
Assistive robots and technologies can play a key role in supporting the independence and social participation of older people, helping them living healthy lives and reducing the burden on caregivers. To support the effective development of assistive robots and technologies, it is important to develop a “living laboratory” to verify and adapt technology in real-life living spaces. The purpose of this study is to validate assistive robots using a living laboratory that simulates typical indoor and outdoor real-life situations. The rationale is to enable evaluation of daily living activities of older people in a simulated living space. To minimize the risk of trauma after falls, a ceiling suspension system was installed in the living laboratory. Six different commercially available mobility and transfer support robots were introduced and tested. We demonstrated that effective scenarios could be implemented using these assistive robots within the living laboratory. We implemented a 3D markerless motion capturing system in the outdoor space and showed that outdoor activities, including walking up and down a ramp, could be verified with sufficient accuracy in three cases: (i) normal use without a robot, (ii) use of the ceiling suspension system, and (iii) use of a mobility support robot on three healthy subjects. These results suggest that the proposed living laboratory can support testing and verification of assistive robots in simulated living environments.
