🧲 PhysicsHydroArm: a Water-Powered Robot Arm with Syringes
A laser-cut robot arm that runs on water: push four syringes on a control panel and the arm turns, lifts, reaches and grabs. No batteries, motors, wires or screws. For Primary 1 to 6.
🧲 PhysicsCrank-a-Light: Make Light with Your Arm and Wooden Gears
Turn a wooden crank, a 75:1 wooden gearbox spins a small motor backwards as a generator, and two LEDs light up: red one way, yellow the other. No batteries and no soldering by pupils. For Primary 1 to 6.
🤖 RoboticsOnyi: a Four-Servo Walking Robot STEM Kit (no glue, no soldering)
A laser-cut biped robot that walks on four SG90 servos, with an Arduino Nano on a breadboard on its head and nine graded Arduino lessons. Screws and tabs only: no glue and no soldering.
