Environment of use testing scenarios. Anti-collision and navigation are tested by driving the wheelchair towards different objects. A 3 m distance was set in order for the wheelchair to achieve a constant velocity of 0.16 m/s. For anti-collision testing: A) stationary objects on centerline; B) moving person that steps onto the centerline when wheelchair is within 700 mm of the person. For navigation testing: C) object on left of centerline; D) object on right of centerline.
