This study develops a new omni-directional wheelchair for handicapped persons working in the office. We consider that fully holonomic motion is not necessary. Thus, the developed omni-directional wheelchair has two omni-wheels for rear wheels and two casters for front. Users move by grasping desks, bookshelves and other furniture, for moving in a small area near the desk in the office, with this omni-directional wheelchair. In other places, for transferring passageways, users drive by both-hands or electric motor. To investigate the effects of the developed omni wheelchair, the time required to move 1〔m〕 lateral side were measured ten times. The results were 11.6±0.7sec (standard wheelchair), 7.1±0.5sec (omni wheelchair), and 4.6±0.3sec (caster shair). Omni-directional wheelchair reduces the time about 39% compared with the standard wheelchair. There was a significant difference (p<0.001) between these two groups, and these results suggested that the omni^directional wheelchair was practical for handicapped people in office works.
