Project Caretaker - ESP32CAM remote controled robot

Project Caretaker is a remotely controlled robot based on esp32-cam and a custom 3D-printed platform.

Main features:

WiFi and BT control; Home Assistant integration; Powerful LED eyes control; 2 control options - joystick and slider; Adaptive web interface for control.

All models have information about printing - quantity and mirroring.

Robot

Esp32cam - the main brain - can also be found under the name AI thinker. Wide-angle camera with extended cable - the viewing angle is not as critical as the cable length. With a shorter cable, it would be more difficult to design an aesthetically pleasing case. Wifi antenna with connector - often comes with the board. 3 li-ion batteries, connected in series (12.6v) with holders. 2 dc-dc step-down converters (12v and 5v). 2-channel motor driver - L298N, L293D or similar - I use L293D due to smaller board dimensions, although I modeled for L298N. 2 GA12-N20 (12V) motors with a gear ratio of 150 (you can take 200 - it will be faster). 12 bearings 6803 (two per wheel). BMS charging board (if you plan to charge in the device). Power switch for battery supply. Mosfet IRLML0030 + 1 kΩ resistor for LED control. LEDs and resistors - to taste. All other parts are made of plastic, printed on a printer (including tracks).

Charging station

Power supply 12.6V 2A. Corresponding power connector for the case. Volt-ampere meter (preferably less powerful up to 5A, otherwise it will not show small current). Contact pair - in my case, copper plates and rods. A pair of springs for better contact during charging.
