Motor pairs and the "move_for_time()" command Pro Preview

Set Up the Motors

To set the pair, we use the command motor_pair.pair(). Here is an example:

from hub import port
import runloop
import motor_pair

async def main():
    # Pair motors on ports F and D
    motor_pair.pair(motor_pair.PAIR_1, port.F, port.D)

The inputs of the motor_pair.pair() command are the following:

• First input = Pair number "motor_pair.PAIR_1"
• Second input= Left motor port "port.F"
• Third input = Right motor port "port.D"

The move_for_time() command

This command allows us to move the tobot for a set amount of time using both motors. Here is an example:

from hub import port
import runloop
import motor_pair

async def main():
    # Pair motors on port F and D
    motor_pair.pair(motor_pair.PAIR_1, port.F, port.D)

    # Move straight at default velocity for 1 second
    await motor_pair.move_for_time(motor_pair.PAIR_1, 1000, 0)

runloop.run(main())

The inputs of the move_for_time() command are the following:

• First input = Pair number "motor_pair.PAIR_1"
• Second input = The duration in milliseconds
• Third number = The steering (-100 to 100)

The velocity input is an optional input, as such we need to call it by name if we want to change it:

motor_pair.move_for_time(motor_pair.PAIR_1, 1000, 0, velocity=280)
