Encoder calibration files missing

Ask
1

Hello,

Recently, I ran the stretch diagnostic tool on our Stretch RE1 and got some errors related to missing encoder calibration files.

stretch_diagnostic_check.py --simple

The error for the right wheel is below:

- test_right_wheel:
  - 'Traceback (most recent call last):'
  - '  File "/home/hello-robot/.local/lib/python3.10/site-packages/stretch_diagnostics_tests/simple_tests/test_SIMPLE_steppers.py",
    line 24, in test_right_wheel'
  - '    self.check_stepper(''hello-motor-right-wheel'')'
  - '  File "/home/hello-robot/.local/lib/python3.10/site-packages/stretch_diagnostics_tests/simple_tests/test_SIMPLE_steppers.py",
    line 52, in check_stepper'
  - '    self.check_stepper_calibration_files(s)'
  - '  File "/home/hello-robot/.local/lib/python3.10/site-packages/stretch_diagnostics_tests/simple_tests/test_SIMPLE_steppers.py",
    line 77, in check_stepper_calibration_files'
  - '    self.assertTrue(etc_exists,''Encoder calibration file missing: %s''%fn_etc)'
  - 'AssertionError: False is not true : Encoder calibration file missing: /etc/hello-robot/stretch-re1-1028/calibration_steppers/hello-motor-right-wheel_75D78AC5504A5230352E3120FF032643.yaml'
  - ''

I can’t upload files, but the full log for the steppers is accessible here: https://drive.google.com/file/d/1s1gC9p9GpKNpM9EOQe_5klXs1H8t4d2K/view?usp=sharing

Calibration files for all four do exist at ~/stretch_user/stretch-re1-1028/calibration_steppers/, though I don’t know if that’s the same.

Are these failures something to worry about? And if so, how can I fix them? Thank you for any help and advice.

Hi @ZachNobles,

Thanks for the details.

stretch_diagnostic_check.py is no longer in use. Could you please run:

stretch_system_check.py

and send us the full output?

If that command does not work, please update your software by following the instructions here.

Then rerun:

stretch_system_check.py

and share the results with us.

Best,
Jason

Hi @ZachNobles

Just following up on this, were you able to run:

stretch_system_check.py

If so, could you please share the full output?

If you ran into any issues updating or running the command, let me know and I’m happy to help.

Best,
Jason

Hi Jason,

Sorry for the slow response. I have run the system check and encountered no errors. Sorry about the diagnostic mistake.
