These six micro robots are like ants: incredibly easy design with 17 grams and strong as bull. The six lightweights pulled together a car that weighs the 1.8 tons. The secret that makes the micro robot of the Hercules, comes from nature: they have adherence to the ground like geckos.
Together the six insect-like robots that bring just 102 grams total weight on the scales to large are capable. In an attempt of at California’s Stanford University, the tiny slowly pull a 1.8-ton car over a concrete floor behind him. Transfer to human proportions it would be as if a team of six people could move the Eiffel Tower plus three statue of liberty.
Strong and controlled adhesive such as when the Geckos
The developers of small powerhouses research laboratory for Biometrics Stanford University and looked down a lot from nature itself, to achieve the impressive tractive effort. Much like ants, which can carry 100 times its own weight, and the individual micro robots are super strong, or even stronger than ants. You are able to pull the 2000 times its own weight behind him.
Helps them see their six legs that looked off the scientists looked by the geckos, which are notoriously easy vertical a strong and controlled adhesive. The liability property can the micro robot and this is crucial depending on the needs and turn off. Is the adhesive surface is required, its surface pulls together scherenarting, and therefore sticks “firmly” on the ground. Once the Scissor mechanism opens, also the liability is lost.
With teamwork, ants move large objects
Now come the ants in the game again, because they are strong not only individually, but also able to tow away together relatively huge objects such as branches or centipede. This can work only in sophisticated team work.
Observing such Ant teams, scientists noticed that the animals were longer chains to support their colleagues, who were themselves directly in connection with the object. The overall strength of the team was raised primarily by, each of the involved ants simultaneously used three of their six legs.
“We have taking into account the dynamics of the team and not only of the individual, we could build our team of micro robots modeled on the ants”, explained David Christensen of the biometrics labor in an interview with the New York Times.
Christensen and his colleagues want to present the results of their research at the International Conference on Robotics and automation in Stockholm.
Christensen and his colleague of Elliot Hawkes researching long Gecko principle. 2014 they presented surfaces, with which people on smooth walls to climb. A technology that interests the United States Army: Who wants to let future vertical walls high crawl their soldiers.
