Putting ants to shame, Stanford University’s Biomimetics Dextrous Manipulation Laboratory has produced tiny robots, which operate similar to inchworms, that can haul 100 hundred times their weight. Huge long-term implications for construction and emergency rescues, like the one we’re currently witnessing in Nepal. From Aviva Rutkin at New Scientist:

Mighty things come in small packages. The little robots in this video can haul things that weigh over 100 times more than themselves.

The super-strong bots – built by mechanical engineers at Stanford University in California – will be presented next month at the International Conference on Robotics and Automation in Seattle, Washington.

The secret is in the adhesives on the robots’ feet. Their design is inspired by geckos, which have climbing skills that are legendary in the animal kingdom. The adhesives are covered in minute rubber spikes that grip firmly onto the wall as the robot climbs. When pressure is applied, the spikes bend, increasing their surface area and thus their stickiness. When the robot picks its foot back up, the spikes straighten out again and detach easily.

The bots also move in a style that is borrowed from biology.•
