Better Power Sources for Robots
Robots, typically, are energy-inefficient. Improving the battery life is a major issue, especially for drones and mobile robots. Thankfully, increased adoption of these systems is leading to new battery technologies that are affordable, safe and longer-lasting.
Work is certainly being done to make the components of a robot more power efficient. But the study mentions robots that need to operate wirelessly in unstructured environments will eventually extract energy from light, vibrations, and mechanical movement.
Research is also being done to improve battery technology beyond the nickel-metal hydride and lithium ion options currently available.
