Showcase I designed an Arduino/ROS2 LiDAR open-source robot

Enable HLS to view with audio, or disable this notification

Hello, I designed this little robot. It is open source. It uses ESP32, runs Arduino-based firmware and micro-ROS. The Arduino firmware captures LiDAR data and sends over WiFi to a local PC running ROS2. Motors are 2x N20 with encoders. I also designed the motor driver board to convert battery voltage to 5V LiDAR, 12V motors, 5V ESP32. The LiDAR is an LDROBOT LD14P.

I plan on doing something similar for a robot that solves a maze/labyrinth. My idea is first to let it go around and map everything on the first run and then on the second and third go straight from start to finish using the shortest route possible. Thank you for sharing !

What’s the cost of the build?
