Turn Oscillation and MicroPython update problems

Robotics XRP

Good day,

On several of the XRPs at our summer camp we are experience a occasional oscillation on turns.

The robot will appear to complete its turn and then vibrate back and forth until given an nudge. It then it continues its program.

I have seen two other reports of the same behavior on other forms.

https://xrp.discourse.group/t/does-the- … work/370/7

Here is the code to reproduce the behavior :

    from XRPLib.defaults import *
    import time
    # drive back and forth to trigger incomplete turn erratic behavior 
    board.wait_for_button()
    # Drive back and forth
    for count in range(20):
        time.sleep(1)
        drivetrain.straight(25, 0.8)
        time.sleep(1)
        drivetrain.turn(180,0.8)

You might have to run it more than once to see the behavior.

I saw it twice the last time I ran it.

We are also finding it impossible to update our MicroPython code.

Any ideas or help will be much appreciated.

Thank you.
