Another bought kit to get something which should work first time, it did in a fashion, so has been a success, but it has spawned a host of modifications and ideas, mainly due to its very low cost.
Because this is a working platform I've made it the basis for my L0Cost Robot project to make something practical that costs relatively little, well compared to the commercial versions, but will need some effort. The route is to modify the original construction and add an ESP32-CAM module to provide remote control.
For code and additional info there's a folder on github
