Tiny robots that can pull objects up to 2,000 times their own weight have been developed at Stanford University. br The miniature robots - dubbed MicroTugs - have power equivalent to a human dragging a blue whale, according to the website detailing the development. br The scientists behind the MicroTugs took inspiration from nature, borrowing techniques used by geckos and ants in their design. br The robots could be used in factories or on building sites. br The team at Stanford, including PhD students David Christensen and Elliot Hawkes, demonstrated a 9g robot that can carry more than 1kg vertically up glass. This is equivalent to a human climbing a skyscraper while carrying an elephant. br Another one - that weighs just 20mg but can carry 500mg, was so tiny it had to be built under a microscope, using tweezers to put the parts together. br The secret to the robots' strength lies in their sticky feet - which is copied from geckos, some of nature's most adept climbers. br "The hardest part in the development of these guys was coming to the realization that this was possible," Mr Christensen told the BBC. br He had worked on making things with the adhesive before but had not considered combining it with robotics. br "When we stepped back and thought about it, this was actually a really great use for our adhesives, with its tiny contact force required, and ability to engage and disengage many times a second," he said. br br br br br br br br br br br br br br br br br br br br br br br br br br br br br br br tiny robots apk tiny robots android tiny robots android cheats tiny robots app tiny robots apk free download tiny robots android free download tiny robots app cheats tiny robots app store tiny robots android games tiny robots android hack tiny robots beta tiny robots band tiny robots build tiny robot bar tiny robot bee tiny robot bar notting hill tiny robot battle tiny robot bicycle tiny blue robots tiny bug robot tiny robots cage the elephant lyrics tiny robots cheats tiny robots cage the elephant tiny robots cartoon tiny robots can find and kill diseases tiny robots.
