Researchers from University of Pennsylvania have developed a robot that feeds on metal and can navigate autonomously without a brain.
The single most important resource in the future will, without a doubt, be energy. Humanity’s energy needs have increased dramatically over the past couple of centuries and that trend will absolutely continue. We’re already experiencing an energy supply problem, as evidenced by our continuing reliance on nonrenewable fossil fuels. Energy storage is also becoming more of an issue as we attempt to move away from those fossil fuels. An electric car, for example, needs a heavy battery. More storage capacity equals more weight, which requires more energy to move — a catch-22. That problem extends to robots, which is why a team of researchers have developed a robot that feeds on metal and can navigate autonomously without a brain.
