Trevor Bommersbach writes, Helsinki University of Technology's WorkPartner platform is a tele-robotics humanoid with 4 wheel independent suspension instead of legs. Seems very capable of doing some real work. More pictures at Impress Watch (where I was first alerted to the robot). Additional photos and video of this Centaur-like robot are available on the Helsinki University website. For more details on the locomotion modes of the hybrid 4-wheeled walking technology, there is a 5 page overview titled, Work Partner, HUT-Automation's New Hybrid Walking Machine (PDF format).
