I really 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 determine methods to boost robotic mobility for specialised functions. The one-legged bot can bounce to a top of over three toes (over a meter) – thrice its personal top – 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.
Watch the little robotic do its factor within the clip under.
Berkeley researchers designed this robotic to leap like a squirrel
So how do you make a robotic land on a department with one foot? It begins with in depth analysis on how squirrels bounce. Some members of the UCB staff 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 drive of touchdown by way of their shoulder joint, after which apply braking drive 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 stability; including a technique to reverse the motor enabled Salto to brake when it landed on a department. The staff 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 probably support 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 would survey Enceladus, a moon of Saturn, the place a single leap might carry the little machine the size of a soccer discipline.
