Looks like they might have started designing a child-sized Ogo. This just popped up on
Facebook.
It looks to be one of the closer images that I've seen of it. I think it has "manual" controls on the joystick that's on the side (not a wheel that you turn with your hand, but a joystick to control the chair with), but other than that, everything I've read is that you can control this thing just by leaning your body a certain way. Just like using a Segway.
