History

The first prototype was completed in 2005 at Shigeo Hirose's lab at the Tokyo Institute of Technology. A product version was developed in 2010 by HiBot, a Tokyo Tech spin-off. The current version is commercially available. The price is dependent on the number of segments and desired sensors.
