Progress is slow, but it is coming together.  

The PCB's have arrived, and I will have all of the components to build one up this week, I should have the drawing finished this weekend, including the components that need to be 3D printed, and the files are accessible here: https://sethlans.io/code/jlbrian/tank

The parts that do not have the academic version watermark were downloaded from https://www.3dcontentcentral.com/

and the files that have funny names are from converting the .igs for rplidar into a solidworks part.  I wanted to see if it would fit on the frame.  https://www.slamtec.com/en/Lidar/A1
