These Tiny Star-Shaped Robots Could Replace Invasive Medical Tests

Researchers from Johns Hopkins University have developed a series of micro-robots measuring just 500 micrometers wide that can be deployed into a human and be used an alternative to the painful colonoscopy. The grippers, which look like tiny starfishes, are activated to collect tissue depending on the surrounding temperature, acidity or enzymes. The arms are designed to clasp around tissue to perform tiny biopsies.

Robotic cheetah can jump over hurdles

MIT’s biometrics robotics lab has shown off a new version of it’s Cheetah robot, capable jumping obstacles up to 45cm (18") high, while running at a steady speed of 8km/h (5mph).

In a show of confidence for the robot, it’s demonstrated here running and jumping without a tether. The calculations for each jump are done autonomously by the robot, with no human action required.

Previously, MIT has said it would like to improve Cheetah’s max speed to around 30mph (50kph), which may require a more complex gait. (Cheetah currently bounds, rather than really cantering or galloping.) MIT also wants to give Cheetah the ability to jump over hurdles while running on softer terrain, which is a more difficult proposition as the robot’s legs have to exert greater force.

Injured robots learn to limp

Like most computers, robots are highly efficient… until something goes wrong. But could they learn to adapt to mechanical faults? Scientists have been deliberately sabotaging walking robots to see how fast they learn to cope.

Scientists Build Robot That Understands Rage

Before you scream in terror, the researchers responsible for the literal rage machine did it for a good reason– to help understand and deal with people who are enraged themselves. But according to artificial intelligence experts, it’s not the angry robots we should worry about, but the ones that show no expression at all…

Kim Horcher and special guest Francis Maxwell (TYT Network host, Movie critic) discuss!
