Tiny Robots Can Pull 100 Times Their Weight

Apr-27-15 Taking inspiration from the gecko, Stanford researchers have created tiny robots able to climb a wall while they pull more than 100 times their weight.

The tiny bots feature an adhesion technology based on the feet of geckos. As the robot climbs, tiny rubber spikes on its feet bend, increasing their surface area and so their stickiness. To carry the weight, the robots moved their padded feet one at a time, a bit like an inchworm. That biologically-inspired gait allows the bot to stay secured to the wall as it “scooches” itself forward.
