Micromouse

thingiverse

This is a micromouse chassis designed around the Romeo BLE mini which is an Arduino compatible microcontroller and Sharp IR analog distance sensors. Together these make a very capable beginner to intermediate micromouse robot. While it may not be able to compete on the same level as fully integrated PCB mice, I designed it to be as small as possible given the components, and lowered the center of gravity as much as I could. The resulting mouse should have a ground clearance of about 2mm. You could potentially file down the unused screw tabs of the 30cm IR sensors to increase the clearance some more if your maze requires it. See the included PDF for detailed dimensions and the angles of the IR sensors. The current design does not account for a gyroscope, you might be able to find one you can connect directly to the controller without making any modifications to the chassis. With my mouse I have not gotten to the point where I need one yet, once I do I will upload an additional design to support it. I will likely look to use this [3-Axis Gyro](https://www.pololu.com/product/2129), and will try to keep the size and layout of the chassis the same to avoid recalibration. I also have designs for maze walls and pillars, and a start/end zone that can record the time it takes the mouse to complete the maze. I will post those as a separate thing soon.
