EPFL scientists from the Biorobotics Laboratory (BIOROB) have developed small robotic modules that can change their shape to create reconfigurable furniture.
Like Lego bricks, Roombots pieces can be stacked upon each other to create various structures. Each 22 cm-long piece, which looks like two large dice joined together, has a wireless connection. Inside are a battery and three motors that allow the module to pivot with three degrees of freedom. The modules have retractable "claws" that they use to attach to other pieces and form larger structures. With a series of rotations and connections, the modules can change shape and become any of a variety of objects and pieces of furniture.
In order to metamorphose and to attach to passive elements, the Roombots need to anchor themselves to something, so the researchers developed a special surface with holes adapted to the Roombots' mechanical claws. Fixed to the walls, floor, and already existing pieces of furniture, these surfaces act as interfaces between the modules and their environment. The little robots can then climb the walls of a room, or attach themselves to "passive" elements on the furniture to form mobile tables or lamps that follow users around the room.
"It could be very useful for disabled individuals to be able to ask objects to come closer to them, or to move out of the way," says Auke Ijspeert, head of the BIOROB.
