A collection of errors we encountered and how we fixed them.

General Troubleshooting Tips

Various Errors we encouterd

Probe Rs being unable to connect to the probe

When trying to connect to the probe we received this error:

    Error: Failed to open probe: Failed to open the debug probe.

    Caused by:
        0: The debug probe could not be created.
        1: An error specific with the selected probe occurred.
        2: The firmware on the probe is outdated, and not supported by probe-rs. The minimum supported firmware version is 2.2.0.

This is caused by too old probe firmware, you can find the updated probe firmware here

Computer and robot state getting mismatched

As of now there is only a one way communication implemented. This can lead to a mismatch in the robot state and the state displayed on the computer (e.g., in the "Menu" functionality).

To fix this you can restart the process.

Motor Directional Inversion

• In case of self assembly motors might get mixed up
• Zumo motors may run in reversed direction (requires negated duty cycle)
• 3pi motors are normal direction
• Needs to be checked before use.
