We figured the robot would need to be designed with a storage space as well as some form of path finding algorithm if we wanted it to be able to carry bottles to the collection area so decided to simply skip the step. Instead, we designed the robot as a bottle cannon that would shoot the bottles in the collection area.

ESP32-CAM firmware
The ESP32 supports ov2640 cameras, which makes it an ideal platform for a DIY IP camera. For this purpose, I wrote a customized firmware for the ESP32 which provides the following features:
Mosquitto
Mosquitto is an open source message broker that implements the MQTT protocol. It is lightweight and is suitable for use on all devices from low power single board computers to full servers.
