Spin the Robot

The project makes a playable spin the bottle type game where it picks someone in the circle who has to do the challenge. The project is made without using a raspberry pie or dev board or a soldering iron making it much cheeper and more accessible to make.


The circuit board will spin the robot as you press the button then when you stop pressing it will slow down. Whoever is in front of the head is then picked to do the dare. The design can also be modify to spin other models.


Supplies

Materials

  1. Bread board
  2. Jumper wires
  3. Button
  4. Dc motor with jumper cables ( I have used a very small motor but I suggest using a larger one.)
  5. Battery holder
  6. 4 battery
  7. Container to house the circuit board can be any nonconductive material

Tools

  1. 3d printer
  2. paint pens
  3. Stanley knife
  4. hot glue gun

Making the Circuit

First we will make the circuit we will do this by connecting the battery ground wire to one of the button wire by placing them both in the same contracted strip of line of 5.

Then on the other end of the button place the wire connect the dc motor wire the same wire on a different line. Next connect the other two wires coming out of the dc motor to the unconnected wire of the battery. This should form a loop.

You can now test to see if the motor spins.

3d print the attached file using 10% infill and it being flat on the bed once fished colour in the robot with the paint marker.

Once dry flip to the uncoloured side and using the Stanley knife and make a small hole in the centre the size of the motor axel.

Assemble

I used a old box but you can use any container you want as long as you can fit the pieces in.

First cut a hole for the button to stick the button out using the Stanley knife then cut a hole on the top for the motor axel to stick out, make sure that only the axel sticks out not the whole motor.

Second fit every thing in the box like shown in the picture then hot glue it all down, make sure the the Circuit is still working as it will become a lot harder to fix mistakes from now.

Next put a blob of hot glue into the hole you made on the robot 3d print and put in onto the sticking out motor axel. Make sure it is NOT resting on the container that is under it as it will stop the motor from turning.

Test

If it is not working test all the connection and the make sure they are not touching any metal as this is the most likely error. Also make sure the hot glue attaching the robot to the motor isnt attached to the box holding it and it is not rubbing.
