Tiny and cheap robot car for inspecting sewer pipes >= 125 mm. With pan servo for the ESP32-Cam module
A simple and small robot car using the well known yellow gear motors and wheels. It carries an ESP32-Cam monted on a pan servo. I used it to inspect my sewer pipes under the basement and up to the curb.
Based on esp32-cam-webserver by Owen Carter.
