MCMiniCar
The mini-car is a proof of concept for the framework, and is simple in its structure.
List of major components.
- Raspberry Pi Zero for interfacing with controller application, in a case
- Raspberry Pi Cam V2
- Propeller Activity Board WX for controls
- 4WD robot car chassis - seeed studio chassis and dc motors
- 2 Channel SPDT Relay power control for the motors
The configuration for this vehicle is pre-loaded in the application.py, and accessed with -config=MiniCar
The used RPI Zero is mounted on the front of the car, with the camera inside the case, pointing forwards.
The project is called MiniCar and is found in the PropellerBoard folder.
The board is connected to a 9V battery to power the motor pins, which are used in controlling the DC motors powering the build.
The 2-channel relay is used in controlling what motors are on and off. Sig pins on the relay is connected to controllable pins on the board, while the motors are connected to always-on powered pins on the board, normally used for motor control.
The motors are connected in serial, with the two motors on the left side connected to the relay controlled by pin 12, and the right ones to the one controlled by pin 13.
