Robots are cool, so check out [Atlin Anderson]’s Spiderbot (video, embedded below) which can be made with 3D printed parts, hobby servos, and ESP32-CAM module for control and a first-person view.

and in that arena [jomjol] has a very neat solution involving an ESP32 camera module and a software neural network to identify meter readings directly. The ESP and camera sit at the top of a 3D ...

Of course, you'll need a camera module that’s compatible with your ESP32 board, and there are plenty of affordable options ...

Additionally, he explored an alternative approach without removing any hardware. Instead, he used the Roomba Open Interface (ROI), a built-in feature of the vacuum cleaner’s original control board.
