Creepy, crawly, and completely engineered by you. The Spider Robot kit lets kids build a spindly mechanical arachnid that scuttles up and down its own string — a motorized STEM project with a satisfyingly spooky payoff.
The kit supplies the body parts, motor, and step-by-step instructions; kids handle the assembly and learn how motors and mechanics make it move. A hands-on build that's equal parts science lesson and Halloween-ready fun.
