Flying robots have some big advantages over their ground-going counterparts, but they're definitely not very energy-efficient ...

Robot uses springy leg . Typically, insect-scale robots fly or crawl, but hopping offers energy efficiency. The MIT robot ...

Insect-scale robots can squeeze into places their larger counterparts can't, like deep into a collapsed building to search ...

MIT's hopping robot is only about 5 cm tall and weighs less than a gram. As soon as the robot jumps on one leg, it converts potential energy from its height above the ground into kinetic energy. On ...
