B·Day Bot is a robot themed after a birthday cake, made with the purpose of spreading joy and happiness in a special day.

Although the robot isn’t finished yet, I have just finished making its remote control system, and I thought that it would be a good idea to share it with the community.

Behind the scenes

This control was built around an Arduino Mini Pro, using the NRF24L01 module to implement the wireless communication.

I don’t have a PCB milling machine, and I have had bad experiences trying to make my own PCBs using acid and other chemical compounds, so I decided to glue 3 perfboards in order to get the shape that I wanted.

The parts that make up the case were designed in SolidWorks and 3d printed using a Flashforge Creator Pro.

In the left side of the case, there’s a hole that allows easy access to the Arduino’s pins, in case it needs to be reprogrammed or debugged.

After all the pieces were printed and tested, I sanded and hand painted them, one by one.

Bottom view. You can see the battery’s door, my signature and the robot’s name.
