Build a piston mechanism with the Hummingbird Robotics Kit! Servos rotate in a circle, but the piston mechanism can be used to transform this rotation into movement back and forth along a straight line.
Popular uses of the piston include flapping wings and jumping characters. What will you create?
Build Time: 45-75 min (depending on skill level and design choice)
