Researchers at Cornell University have been working on batteries that can 'flow' through the internal structures of robots, kind of like how blood in humans' veins powers our bodies.
as well as wireless capabilities for control or access to more computing power. Both robots are open source and modular as well, allowing a range of people to use and add on to the platform.
In the same way that terrestrial life evolved from ocean swimmers to land walkers, soft robots are progressing, too, thanks to recent research in battery development and design.
