This is an autonomous robotic dust sweeper. It's not meant to be state-of-the-art, but a fun way to learn about robotics. Nonetheless, it's not totally useless :)
Building it might not be the easiest thing in the world, especially since I have little time to create proper documentation. If you have some coding skills, though, I bet you'll be fine.
It's built in a modular way, so you can experiment replacing some parts without having to re-print too much stuff.
The attached PDF shows a minimalistic reference of the connections I made: I suggest you double check them with the pin numbers in the code :) Also make sure the motors are spinning the right way, using the web page detailed in the meta-sweeperbot readme.
1x FHL-LD20 LIDAR (https://www.amazon.it/gp/product/B0C624D5PS/). The code I used referenced a LD14P model, so that might be an alternative name for it, or a similar model.
1x L298N motor driver (https://www.amazon.it/gp/product/B09TJZ953V/)
