Scientists at UC Berkeley designed obstacle courses to better understand how squirrels gauge and adjust their movements on the fly, as they dart away from predators and avoid potentially fatal falls.

Scientists at UC Berkeley designed obstacle courses to better understand how the bushy-tailed rodents gauge and adjust their movements on the fly, as they dart away from predators and avoid potentially fatal falls

The hope is that the research could one day help to build more agile robots with better decision-making skills. The scientists were keen to learn how the animals would negotiate a critical trade-off: Moving towards the end of a perch reduced leaping distance, but compromised stability and jumping force as the launch platform became more wobbly.

If they jumped too far, they would swing over the target perch and perform a roll around it to stick the landing.But the most surprising innovation came when the squirrels didn't aim for the target branch directly at all, instead bouncing off an adjacent wall to make the most challenging leaps, akin to parkour.
