Northwestern University engineers have created the smallest-ever remote-controlled walking robot, a tiny peekytoe crab just half a millimeter wide.
This miniature robot can walk, bend, twist, turn, and even jump.
The crab robot's movement is powered by the elastic resilience of its body, constructed from a shape-memory alloy that changes shape when heated by a laser.
This heating and cooling cycle creates locomotion, allowing the robot to move in controlled directions based on the laser scanning. The team also developed similar millimeter-sized robots resembling inchworms, crickets, and beetles.
The technology could eventually enable micro-sized robots to perform practical tasks in confined spaces. John A. Rogers, leading the experimental work, envisions these micro-robots as potential agents for industrial repairs or minimally invasive surgical procedures.
Happynass thought: Are we going to be invaded by insects and animals, controlled by artificial intelligence made by humans, anytime soon?
