Blocks code - stop motor with time

[amberneb]

In blocks version is there a way to have your motor run for a set amount of time? Our FLL team wants to have our drive train run for a set number of degrees OR for a set amount of time to prevent it from stalling.

You can use await multitask(motor.run_angle(deg_per_sec, deg), wait(ms), race=True) for this. (see link for equivalent block)

If the timer finishes first, it will cancel the motor command or if the motor command finishes first, it will cancel the timer.

You can start the motor, wait for as long as you like, and then stop.

run for a set number of degrees OR for a set amount of time to prevent it from stalling.

If you mean run for degrees unless it takes too long, here's an example from this chapter in the learn guide:

"This can be very useful if you want to move a fixed distance but don’t keep trying forever if you hit a physical endpoint."
