4. Drift

In this project, you will learn how to make the Zeus Car drift.


How to do?

  1. The ESP32-CAM and the Arduino board share the same RX (receive) and TX (transmit) pins. So, when you’re uploading code, you’ll need to first disconnect the ESP32-CAM to avoid any conflicts or potential issues.

  2. Open the 4_drift.ino file under the path of zeus-car-main\examples\4_drift.

  3. After the code is uploaded successfully, slide the power switch to ON to start the Zeus Car.

  4. Zeus Car will now move forward for 0.5 seconds, then drift 90 degrees left, and so forth. You can try changing 45 (rot) to another value or a negative number to see how the drift angle and direction change.

How it works?

The drift of the Zeus Car is achieved by adding the drift parameter drift to the move function carMove().

void carMove(int16_t angle, int8_t power, int8_t rot, bool drift)
  • angle: The direction you want the car to move. use the head of the car as the 0 degree and increase the angle in counterclockwise direction.

  • power: The moving power, the range is -100% ~ 100%. When power is positive, the car moves forward, and vice versa, it moves backward.

  • rot: Rotation power, the range is -100% ~ 100%. When rot is positive, the car turn counterclockwise, and vice versa.

  • drift: Default is false, when it is true, drift mode is enabled.

So the different power and rot values will change the drift angle and direction of the Zeus Car.
