Note

This channel is only for questions and bug reports related to secondary development interfaces. For robot hardware failures, after-sales maintenance, or similar issues, please contact the relevant delivery, operations, or after-sales teams directly. Unrelated issues will not receive a response. Please describe the issue in detail in the form, preferably with reproducible steps. Reports with sufficient information and clear descriptions will be prioritized. Vague or overly general reports may be assigned lower priority and may be ignored. Please fill in all required information carefully. Tickets with inconsistent or casually entered information may be ignored. Each ticket should focus on a single issue or a single category of issues. Please do not combine multiple issues into one ticket, as this will significantly delay processing.
