When mechanical engineering graduate student Faye Yap saw a dead spider curled up in the hallway, it got her thinking about whether it could be used as a robotics component.
They called this new type of robotics 'necrobotics'.
Weirdly, spider legs don't have muscles for extension, but instead move their legs via hydraulic pressure – they have what's called a prosoma chamber, orSo, the team inserted a needle into the spider's prosoma chamber and created a seal around the tip of the needle with a glob of superglue. Squeezing a tiny puff of air through the syringe was enough to activate the spider's legs, achieving a full range of motion in less than one second.
They then demonstrated the use of a dead spider to pick up delicate objects and electronics, including having this necrobotic gripper remove a jumper wire attached to an electric breadboard and then move a block of polyurethane foam.
