Why bother to design your own robots when you can just reuse what nature created?
This was the thought process behind a research project from engineers at Rice University who successfully transformed dead spiders into robotic gripping claws. The scientists have dubbed their new area of research “necrobotics” and say it could create cheap, effective, and biodegradable alternatives to current robotic systems.
So why spiders? Well, while humans move their limbs using pairs of antagonistic muscles, like biceps and triceps, spiders’ legs contain only a single flexor muscle that draws the leg inward. This is opposed by a hydraulic system: a chamber in the center of the spider’s body (known as a prosoma) pushes out fluid to open the leg, with…
