A quasi cyborg spider robot that moves on hydraulic pressure The quasi-cyborg spider is a groundbreaking example of necrobotics, where a dead spider is repurposed as a robotic gripper by utilizing its natural hydraulic limb system. Developed in 2022 by engineers at Rice University, the innovation takes advantage of the spider’s unique anatomy—its legs extend and retract through hydraulic pressure rather than muscles. By inserting a microneedle into the spider's prosoma and injecting air, researc
