bosdyn.client.spot_check.run_spot_check(spot_check_client, lease, timeout_sec=212, update_frequency=0.25, verbose=False)

Run full spot check routine. The robot should be sitting on flat ground when this routine is started. This routine calibrates robot joints and checks camera health.

Parameters

• spot_check_client (SpotCheckClient) – client for calling calibration service.

• lease (Lease) – A active lease. Spot check can be overridden at any time with another command.

• timeout_sec (float) – Max time this function will block for.

• update_frequency (float) – How often this function will query feedback.

• verbose (bool) – Periodically print status.

Returns

Joint and camera check and cal results.

Return type

SpotCheckFeedbackResponse

Raises

bosdyn.client.exceptions.Error – Throws on any error failure.

bosdyn.client.spot_check.run_camera_calibration(spot_check_client, lease, timeout_sec=1200, update_frequency=0.25, verbose=False)

Run full camera calibration routine for robot. This function blocks until calibration has completed. This function should be called once the robot is powered on and standing in the configuration described in user documentation.

Parameters

• spot_check_client (SpotCheckClient) – client for calling calibration service.

• lease (Lease) – A active lease, used by calibration routine to issue robot commands. Lease keep alive internally managed by service. Revoke lease to end routine at any time.

• timeout_sec (float) – Max time this function will block for.

• update_frequency (float) – How often this function will query feedback.

• verbose (bool) – Periodically print status.

Raises

bosdyn.client.exceptions.Error – Throws on any calibration failure.
