After watching a recent youtube video about MicroMouse, I keep thinking about building my own and using it as a way to explore and learn about different kinds of code than the things I typically write for my job.
Is anyone else interested in this?
Update: People are interested, and we’re making a little community here
This thread ended up mostly focusing around controlling the Pimoroni Trilobot, but feel free to tag future threads/questions with toy_robot and I’ll try to link to resources from this first post:
- Motor control and button inputs got reverse engineered and there are modules to control them in this github repo
- Troubleshooting the SN3218 for controlling the RGB LEDs
- Jon Carstens got it working with sample code here: Anyone interested in building Micromouse bots with Nerves? - #36 by jjcarstens
- A thread to explore using the TMF8821 sensor for navigation

Those were the best 25 minutes I spent. I just got started with embedded development working through “Build a Binary Clock with Elixir and Nerves” 2 days ago. I’d love to participate in this, though I’ll have a lot of learning to do.

I would also be interested! Haow do you think we should collaborate on this?

I don’t imagine we’ll have enough people all in one-place to do face-to-face meetups, but I was thinking we could start finding kits or parts to build our own “mice” (something that can fit a raspberry pi zero 2?) and share our progress as we go?
Maybe some folks from the Nerves Meetup would be interested as well? @amclain

I started working on a cad model based on some parts I can order from The Pi Hut Onshape

could be fun - this kit might be useful:
also using esp32 hw could be possible with GitHub - atomvm/AtomVM: Tiny Erlang VM · GitHub

I haven’t looked at the AtomVM project recently. It’s really cool that they’ve added support for the rpi pico. Maybe we should give it a try!

This sounds good! Timewise i wouldn’t be able to make face-to-face meetups, but sharing progress as we go is what i am looking for
mmmries
Same for me. I’m living in London and can’t attend the evening meetups in the US. So posting progress online will work well for me. Let’s just start here in this thread for anyone interested and see if it gains momentum.
I think I’ll start with that Trilobot Base Kit posted above, but use a pi zero 2 (I have one on hand)

It looks like this sensor might be an interesting option to swap out for the ultrasonic sensor that comes with the trilobot SparkFun Qwiic dToF Imager - TMF8821
There is already an elixir library written to interface with this sensor and it gives back measurements from 1cm - 5m in a 4x4 grid GitHub - pkinney/tmf882x · GitHub

If you can send me the elevator pitch and where people should go to join the project, I’m happy to share it. If you’re able to record a short video, that would be more impactful than text.
