The emerging field of telepresence and telerobotics has produced some fairly out-there forms to carry out their functions, and researchers at Yamagata University in Japan don’t seem to have any problem pushing that envelope.

The MH-2 (for “miniature humanoid”) is a remotely controlled robot that lives on your shoulder and conveys a person’s gestures and movements from a distance.
