Necrobotics is using dead spiders as robotic hands

Spiders are awesome. If you’ve ever seen a dead spider you know that they curl up when they die. They do this because that’s the normal position for the legs; to keep the legs spread out the spider pushes fluid into the legs, which straightens them. Yes, spiders use hydraulics.

So some enterprising engineering people at Rice University decided to use a syringe to actuate this hydraulic system. And she can use it to pick stuff up and put it back down. It turns out that dead spiders can be used as robotic claws. Neat!
