You can build all of the parts for Mirobot yourself. Here are a few tips to get you started.
Get the PCB made
There are currently two PCBs used for Mirobot; the main PCB and the WiFi module. These can both be downloaded from GitHub. Check the releases and download the latest. You can use the Gerber files in this release to send somewhere like Ragworm and they'll send you back your PCBs
Buy the parts
You'll need some parts to make Mirobot work. They've been chosen to be quite low cost so shouldn't break the bank. Apart from the electronics, you'll need:
- 2 x 28BYJ-48 stepper motors. These can be picked up pretty easily on eBay. Make sure you get the ones with a 1:64 gear ratio
- 1 x Pololu caster wheel.
- 1 x 9g Micro Servo. I've successfully used the ones from Tower Pro, but they should all work I think
- 1 x 5 AA Battery holder
- 2 x Elastic Bands
- 2 x M3 x 16 machine screws
