Tiny Origami Robot

      

This 1.7cm long Tiny Origami Robot made by Shuhei Miyashita and colleagues at Massachusetts Institute of Technology, is self-folding, walks, swims, and then recycles itself when its job is done. This tiny machine made of plastic and containing a magnet can be "programmed" by an external magnetic field. It also contracts when heated, created from a flat sheet that folds up along cut marks at a temperature of 65°C, thanks to polyvinyl chloride. Moreover, this robot can dissolve in either water or acetone, leaving only the permanent magnet behind.
