Abstract
This letter describes sheet-type robot, which can change its shape from a planar sheet to three dimensional structure, move omni-directionally and have transporting capacity. Although many researches on transformable robots are reported, the transformation capability is limited and the structure is complex. A sheet-type robot has a potential to be miniaturized due to its features and to become several complex structures like Origami, a Japanese art work. We achieved three dimensional structure from a sheet-type robot and could confirm its potential.
