Roomba Lollypop Thrower

Roomba Lollypop Thrower

Group project for Ideas & Technologies course at the Iceland University of Arts in Reykjavík.

By Julia Kosciuczuk and Valdís Mist Óðinsdóttir.

• Lasercutter
• 3D printer

1. Take plywood sheet and laser cut the base of the lollypop thrower. (The base fits Roomba 866 model).
2. Take plexiglass and laser cut attachments for the thrower.

SEPARATE THEM INTO GROUPS SO IT IS EASIER WHEN GLUING THEM TOGETHER.

3D Print the spoon that will throw the lollypops using the file down below.

Wire the electronics according to the instructions above.

Now code the electronics. All files are available down below.

One covers the IR connection with the circuit and the speed of motor and throw.

The second defines the colour of the LED strip (Neon Pink).

Carefully glue all the plexiglass attachments, using epoxy or plastic adhesive. The dome is specifically tricky, so do not rush it.

• Screw the spoon in the correct spot, so it throws without colliding with the dome.

After gluing, you should have:

2x Battery Box

1x Feeder for the lollypops

1x Attachment for the robot (the top part above the visible battery pack)

1x Motor stand

• Arrange all the parts so they do not collide. Make sure the wires are secured, without the risk of disconnecting from the circuit.

• Glue the feeder sideways to the stand as seen in the photo.

• Tape the LED strip to the base however you want. It runs on the second battery pack which is on the base so make sure it's secured.

Now that the dome is hard, we melt hole in it so we can throw lollypops.

• Simply take long piece of metal, preferably stick alike, bring it to high temperature and melt preferred size.

• Take the laser cut top of the dome (the middle circle) and by using hole saw drill hole so that the lollypops can be easily thrown into the feeder.

• Glue the top using epoxy and wait for it to harden.
