No, not a power converter. We’re talking about Optimus Prime and the like.
Researchers at MIT’s Center for Bits and Atoms have created a tiny robot that assembles itself into different shapes when hooked up to other robots. The gizmo is called milli-motein since its creators drew inspiration from bio-proteins that can reconfigure themselves. The idea is to create a robot workforce that doesn’t have to be built with specialization – the same robot can do different tasks simply by changing its shape.
