User-Environment Based Navigation Algorithm for an Omnidirectional Passive Walking Aid System Naemeh Nejatbakhsh, Tohoku University, JapanKazuhiro Kosuge, Tohoku University, Japan • Omni RT Walker-II (ORTW-II) is a passive type omnidirectional walking aid system. • Magneto-Rheological (MR) brakes are utilized for passive control or ORTW-II • Potential canal is a new concept proposed to realize indoor navigation using this aid system. • Realtime modification of potential canal is discussed to avoid transient obstacles and support while walking.
