The small boat of STAR (Sprawl Tuned Autonomous Robot) moves both on absolutely smooth surface, and on the relief. Such boat can serve as the spy, it is perfectly shown on nizherazmeshchenny video.
The boat was developed by students of the Californian institute in Berkeley. The most part of details, without considering an electronic component, were made on 3D the printer.
The boat moves very quickly, it even is capable to squeeze under a door and to overcome various obstacles. His behavior is similar to habits of some insects.
The case and details of a boat were written on 3D the ProJet 3000 3D printer. Developers say that the project is already complete, and they are ready to make hundred parts or thousands copies of robots of this type.
