This week's video was brought to our attention by a post on the
DPRG mailing list. The video shows a 2006 Japanese research robot
developed at the Hirose-Fukushima
Robotics Lab. The robot has a hybrid locomotion system with legs
that end in wheels. The wheels can be rotated so that the hubs
face the ground and they act as feet for walking. The wheels can
to act as normal wheels, allowing the robot to roll like a roller
skater when the legs move appropriately. The result is remarkably graceful.
