Autonomous 1/28 micro car from scratch

Here is the next step ! Full autonomous.

Hardware config :

Raspberry Pi CM4

IMX296 global shutter camera

Donkey car open source software

Here is a video of the line follower !

Some news ... I am currently making some tuning to go faster with the line follower. A video will come soon. I hope so ...

Building and testing the car.

I made a radiocontroler  in order to check if everything  is OK.

Radiocontroler is based on an STM32F103  module + a CC2500 Rx/Tx module.

Car is working great but I have to test  it on a less siplery surface,  the motor is very powerfull and I have wheelspin at 30% of throttle.

In order to test the basic functions of the car, I will make a radio controller.

I made a quick design of the controller with previous submodules that I have done in the past :

- STM32F103 board module

- RF TX/RX CC2500 with PA + LNA board module

- Step Up + battery charger + ON/OFF button board module

- Screen

- Majority of through holes components

- Assembled with my hands (no machine)

Here is a view of the RF controller :

Integration of the ESC and a telemetry module on an UNO board :

This board will have the following characteristics :

- 1 Atmega328P for the Uno Board (Top Face) --> It will send the instruction to the Servo and ESC , will communicate with several sensors and a Raspberry Pi

- 1 Atmega328P for controling the motor (throttle, brake) (bottom Face)

- 1 2.4Ghz telemetry module (CC2500 + PA / LNA) that I made in a previous project (bottom Face)
