• | UM developed "NavChair" for severely
disabled users. |
|
| |
• | Some users cannot control their
wheelchair accurately with a joystick,
because of tremor or other limitations. |
|
| |
• | Obstacle avoidance on NavChair
overcomes these problems: |
|
| |
• | User gives general direction of travel
with joystick; NavChair follows this
direction. |
|
| |
• | When obstacle is encountered,
NavChair steers around it while trying to
maintain user-specified direction as closely
as possible. |
