ESP32 Camera Bot

<h3>ESP32 Camera Bot</h3><h3>Motivation</h3><p>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: <a href="https://medium.com/@mudassar.tamboli/esp32-ov7670-websocket-video-camera-26c35aedcc64">Websocket Video Camera</a>. 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.<br/>I liked the <a href="https://www.thingiverse.com/thing:700835">Drogerdy 2.0</a> because it uses the standard geared motors which I had lying around. On the other hand, the tracks of the <a href="https://www.thingiverse.com/thing:1906831">MR-4</a> 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...</p><h3> </h3><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p> </p><p><strong>Printer: </strong></p><p>i3 MK3</p><p> </p><p><strong>Supports:</strong></p><p>Yes</p><p> </p><p><strong>Resolution: </strong></p><p>OPTIMAL (0.15mm)</p><p> </p><p><strong>Infill:</strong></p><p>As given in the original model</p><p> </p><h3><strong>Filament:</strong> Prusa PLA Prusa Orange, black, silver </h3><p><strong>Notes: </strong></p><p>Supports from build plate for the camera front and display back.

Since I liked the tracks of the MR-4 more, I used them, but had to modify the cogwheels to fit.<br/>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.<br/>For designing and modifying the parts I used FreeCAD.</p><p> </p><p>This model is based on</p><ul><li>Drogerdy 2.0:  <a href="https://www.thingiverse.com/thing:700835">https://www.thingiverse.com/thing:700835</a></li><li>MR-4:              <a href="https://www.thingiverse.com/thing:1906831">https://www.thingiverse.com/thing:1906831</a></li></ul><p> </p><p>Category: R/C Vehicles</p>
