Insect-Like Robots Walk Faster When They Ignore Nature

Three legs good, two legs better. At least, that’s the case if you’re counting the number a six-limbed robot should leave on the ground to move quickly.

Roboticists often borrow from nature when it comes to walking styles—but that doesn’t mean the movements are necessarily the most efficient. Most insects leave three of their six legs on the ground as they scuttle, but they do so to ensure they maintain enough friction against a surface to allow them to climb slopes.

Now, calculations published in Nature Communications reveal that leaving just two feet on the floor can make movement faster on the flat.

Testing that idea out using a robot modeled on a fruit fly yields results that speak for themselves: the top robot leaves three feet on the floor, while the bottom one leaves just two.
