NewScientist says that Japanese researchers have created the first two
walking robot that can carry a person It's probably not correct
to call it a wheel chair. The bipedal (two legged) chair
WL-16 can walk smoothly even if the person in the chair
has 12 actuators for going forward, backward, or side to side. The
researchers hope to
make the robot someday go up and down stairs (safely). This could be
the new thing in (for lack of a better term) wheel chairs. However,
if it were to step on your foot with it's big flat feet, you might
tend to disagree.
I intend to wait for a new and improved model with at least four
legs. Six or more would be better because creatues with more
than two legs can travel faster than creatures of equal size with
just two. Check out the stride length for a dog if you don't believe
this. A walking dog doesn't appear to move one of its legs through
a large arc, but the stride length is much longer because during
the time that leg was raised, the dog's body has been carried
forward by its other legs.
Bug-like chairs would also be lower slung and easier to get on
and off, and might be programmed to do useful chores around the
house. Carpentry for example, based on the design of a carpenter
ant, of course.
How do you reach the door knob?
The door bar maybe with your feet?
It really needs to have knee joint and hip joint legs. Then it can have
a much better gait and walk to it.
This design will be hard on the back.
