Robotic Legs Recycle Energy

Boffins from the Oregon State and Carnegie Mellon Universities managed to clash their brains together to come up with robotic legs that are capable of recycling energy stored whenever the leg is bent, just like how animals do it. No surprise then that humans are also able to recycle approximately 40% of their energy with each springy step, and to take that idea and translate it into a robotic leg would mean lighter exoskeletons and prosthetics in the future, since the motors and batteries need not have to be that large nor heavy.
