position calibration for linear actuator in python

To calibrate the position of a linear actuator in Python, you typically need to provide the actuator with a reference point or range and then map the actual readings to the desired positions.

Here's a simple example using Python to calibrate the position of a linear actuator based on some reference points:

main.py
# Define the reference positions and actual readings
reference_positions = [0, 50, 100, 150]  # Reference points in millimeters
actual_readings = [100, 400, 700, 1000]  # Corresponding actual readings from the linear actuator

# Calibrate the position based on the reference points
def calibrate_position(actual_reading):
    # Assuming a linear relationship between reference positions and actual readings
    # You can use more advanced calibration techniques for better accuracy
    position = np.interp(actual_reading, actual_readings, reference_positions)
    return position

# Example usage
current_actual_reading = 600  # Example actual reading from the linear actuator
calibrated_position = calibrate_position(current_actual_reading)
print(f"Calibrated position: {calibrated_position} mm")

In this example, the calibrate_position function interpolates the actual reading of the linear actuator to determine its calibrated position based on the defined reference points. You can adjust the reference points and actual readings to suit your specific linear actuator setup.

Remember, calibration might involve more complex calculations depending on the accuracy required and characteristics of the linear actuator.
