I like me a bio-inspired robotic that pulls off difficult feats by taking cues from the pure world. College of California, Berkeley (UCB) researchers have now proven off the one-legged Salto bot mimic the way in which squirrels leap effortlessly between precarious branches and stick the touchdown on the very first try.
Since 2016, Salto has performed a giant function in serving to engineers at UCB work out methods to boost robotic mobility for specialised purposes. The one-legged bot can soar to a peak of over three ft (over a meter) – thrice its personal peak – and even ricochet off a wall.
For Salto’s newest trick, the hopping bot leapt onto a dangerous department and balanced with out toppling over.

So how do you make a robotic land on a department with one foot? It begins with in depth analysis on how squirrels soar. Some members of the UCB crew offered a paper on this biomechanical evaluation, which appeared within the Journal of Experimental Biology final month.
Because it seems, when squirrels land on a department, they direct the pressure of touchdown by way of their shoulder joint, after which apply braking pressure with their legs to keep away from falling forwards or backwards.

Subsequent, the researchers went to work enhancing Salto’s capabilities. The bot already had a motorized flywheel to assist it steadiness; including a strategy to reverse the motor enabled Salto to brake when it landed on a department. The crew additionally added adjustable leg forces to assist it compensate for over- or under-shooting when it landed, along with the flywheel’s impact.
With that, Salto and different robots that use this tech might doubtlessly help in search-and-rescue operations by navigating nimbly by way of catastrophe areas, assist examine infrastructure, and even discover low-gravity celestial our bodies.
To that finish, Justin Yim, who co-authored the paper on leaping robots that appeared in Science Robotics, is growing a one-legged bot that might survey Enceladus, a moon of Saturn, the place a single leap might carry the little machine the size of a soccer subject.
