ESP32 Camera Bot

ESP32 Camera Bot

Motivation

I searched for a nice vehicle to test the ESP32 camera bot source code. The code is based on the nice project by Mudassar Tamboli and bitluni. See here for details: Websocket Video Camera. I had to modify the code a bit to add an I2C display which did not work with the I2C bitbanging code of Mudassar Tamboli.
I liked the Drogerdy 2.0 because it uses the standard geared motors which I had lying around. On the other hand, the tracks of the MR-4 were using filament as connecting element instead of something that needed printing. This implied to adapt the cogwheels. Then, I wanted a housing for my camera and a holder for a display to show the IP address of the microcontroller. By Using a DRV8833 motor driver I could live with a standard power bank for a supply. I thought it would be a nice idea to use a power supply with built-in solar cells for a green touch...

Supports from build plate for the camera front and display back. I needed 30 Track elements per side.

How I Designed This

Changes To The Original Model

I did not like the tracks because of the need to print the joining pins. Since I liked the tracks of the MR-4 more, I used them, but had to modify the cogwheels to fit.
Further, I created a front for the camera and a back for the display to fit into the body. Additionally, I made a carrier for the power bank and the circuit board.
For designing and modifying the parts I used FreeCAD.
