It's powerful, too. The initial design can lift seven times its own weight, but you can add more components for extra strength or to handle complex movements. And notably, you can scale the size of the parts to tackle very large or very tiny projects. Until now, you typically needed specialized methods to make motors work at either extreme.

While this is is just a "first step," MIT sees vast potential. It could lead to standardized part sets that help assemble task-specific robots without needing to design new manufacturing bots every time. You could also see more extra-small robots capable of working in tight spaces. Either way, this could help robots transition from expensive, niche machines into something relatively commonplace.
