US researchers want to apply the leg spines of spiders and insects to robots. The researchers found that the modified robot could simply cross a wire net that formerly blocked its trail. And they state the innovative design could be helpful for rescue robots that require covering complex ground. They cautiously observed the slow-motion video of arachnids crawling across wire net and observe just a 22% sluggish from running across solid ground. It seems that, the insects are able to allocate their weight just so across their many legs, so that there's typically one leg that take another's fall and avoid the insect from getting too immovable. This natural process is being useful to robotic limbs, supporting crawling creature to manage across less than perfect circumstances by using automatic response.
