Specified path is empty

What does -13 mean?

This return value from the OR_PATH_REPLAY() function signifies that the path identified by the PATHID exists on the Compute Box but contains no valid movement data. This prevents the KUKA KRC4 robot from replaying any motion, as there is no path to follow.

• The path recording session was started but no actual robot movement was recorded before stopping the session.
• The path data became corrupted, leading to an empty path file despite a recording attempt.
• An incomplete path recording or saving process resulted in a zero-length path being stored.
• The path was exported from another system and imported onto the Compute Box incorrectly, resulting in an empty file.
• Insufficient storage space on the Compute Box may have resulted in an empty or truncated path file.

Click steps to track your progress.

1. 1

   Re-verify the path by attempting to visualize it or checking its properties through the OnRobot software interface on the KUKA HMI or the Compute Box webpage.

2. 2

   Confirm the recording process: ensure that the KUKA robot was physically moved along the desired path while 'Start Path Recording' was active and 'Stop Path Recording' was pressed afterwards (pages 20-21).

3. 3

   Re-record the path, paying close attention to all recording steps to ensure valid movements are captured and saved properly.

4. 4

   Check the storage capacity of the Compute Box to ensure there is enough space for path data and that no storage errors occurred.

5. 5

   If the path was imported, re-export the original path file from its source and re-import it to the Compute Box to rule out transfer issues.
