Useless Robot That Doesn't Work

This instructable outlines how to make a contraption that is supposed to be hung on the ceiling and when someone walks underneath it, it releases a glitter bomb.

However, since this is a crappy robot, it does none of these things. The box is too bulky, and the servo motor is too slow, so by the time it drops its contents onto whatever is below it, the person has already moved on.

It's completely useless and it's a failed project, but that's in the spirit of crappy robots.

For this crappy robot, you will need:

• Cardboard box
• Arduino Uno
• Breadboard
• Three black male-male wires
• Three red male-male wires
• Two yellow male-male wires
• One green male-male wire
• One blue male-male wire
• Servo motor
• Distance sensor

This is a box that was slightly modified from another box. All that was done was the top was cut off, and then a larger piece of cardboard was taped to the top to make a tuck flap box.

Here is a printout template to help you make a tuck flap box if you don't feel like making your own.

Using the file attached and arrange the uservo motor, distance sensor, and wires on the breadboard and Arduino as depicted.

Afterwards, upload the attached code to the Arduino.

Grab the box that you had made before and then tape the servo motor to the side of the box, near the flap. It should be placed so that the servo motor stops the flap from opening.

The distance sensor should be on the ceiling, next to the box.

When the someone is not under the box, the servo motor should be across the flap, holding it back. And when it senses someone under the box, the servo should move to allow the box to open.

However, this failed project didn't work.
