Introduction: Dancing Toy Robot
This is a project for a Basic Electronics Course at betalearn.org (https://goo.gl/7x6QwY)
The idea was to add electrical parts to an ordinary clockwork toy so that it could move on demand.
Step 1: Materials and Tools
-Common 5V DC motor, pushbutton, jumper cables, micro-usb adapter and breadboard
Step 2: Tear Down of the Toy
Take the screwdriver and unscrew the necessary parts. If you try to disassemble each and every part of the toy, it may end up becoming difficult to put it all together again. Leave the spring and the unnecessary gear out.
Step 3: Re-Build With the Motor
Leave only the relevant gears in the gearbox and glue the axis of the motor to the main gear. Be careful (and quick) if you intend to do it with loctite (apply the glue yo the gear and not the motor). Rebuild the toy checking that after every step the mechanical parts work as expected. You can use the suggested electric sketch.
Introduce the robot in a polyestyrene bar (you will need to drill the correct hole in the polyestyrene bar) and attach sticks to the sides to prevent it from rotating. Now you should have your own dancing robot!
