Docs for the Move Back code snippet

Description

Move the Vex V5 Robot backward autonomously after running the program from its corrent position.

Code Snippet

from vex import *

# Begin project code
# Driving in reverse  - Moves 7ft back from its current position
drivetrain.drive_for(REVERSE, 1000, MM)
drivetrain.drive_for(REVERSE, 1000, MM)
drivetrain.drive_for(REVERSE, 200, MM)

# End of program

Additional Notes

The drive_for function is used to move the robot backward. The function takes three parameters:

  • The direction to move the robot is. In this case, the robot is moving backward.
  • The distance to move the robot. In this case, the robot is moving 7 feet backward.
  • The unit of measurement for the distance. In this case, the robot is moving 7 feet backward in millimeters.

The drive_for function is called three times to move the robot backward. The first two calls move the robot backward by 3 foot each. The last call moves the robot backward by 2 inches. This is done to ensure that the robot moves backward in a straight line. The robot tends to drift to the side when moving backward for long distances. The drive_for function is called multiple times to correct this drift.
