'Hedgehog' robots hop, tumble in microgravity

Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can’t operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous. Enter Hedgehog: a new concept for a robot that is specifically designed to overcome the challenges of traversing small bodies.

Self-driving golf carts

An experiment conducted over six days at a large public garden in Singapore demonstrated self-driving golf carts that ferried 500 tourists around winding paths trafficked by pedestrians, bicyclists, and the occasional monitor lizard.

Completely paralyzed man voluntarily moves his legs, scientists report

A 39-year-old man who had had been completely paralyzed for four years was able to voluntarily control his leg muscles and take thousands of steps in a robotic device during five days of training with the aid of the robotic device combined with a novel noninvasive spinal stimulation pattern that does not require surgery, a team of scientists reports.
