Robot chassis
Big Dog
A chassis platform for evaluating material-handling and custom robot integrations.

Current specifications and project compatibility require confirmation. Check the sources and conditions before selecting a configuration.
Application review
Start with the mass of your load and top module, their dimensions, and the route the robot needs to follow. Confirm the final configuration before selecting this chassis.

Questions & answers
How do I check Big Dog map quality and startup localization?
Applies to: Big Dog; map and charging-marker deployment cases
Look for doubled walls, distortion or unclear working areas, and check whether live lidar points align with mapped obstacles. Verify the calibrated charging-station marker, physical startup position and virtual walls. In long corridors, compare the outbound and return mapping passes. Recheck the map and site if these do not align.
Why can Big Dog remain stationary even when the navigation screen looks normal?
Applies to: Big Dog; task, emergency-stop and docking-state cases
Check emergency-stop, drop-detection, wheel and docking states before issuing more commands. Recorded cases also involved serial communication and power-board verification faults. If a stale docking state is confirmed and it is safe to end it, stop docking through the interface. Escalate persistent faults with the logs.
What should I check when Big Dog door control or a call button fails?
Applies to: Big Dog; door integration, including a customer-developed application
Confirm that the required module is installed and detected, then inspect serial status and the specified wiring. Cases included a missing call module, LoRa module or cable faults, and a receiver that stopped responding. Verify the physical door state as well as the application message.
What should I check if Big Dog reports an offline elevator gateway or the wrong floor?
Applies to: Big Dog; configured elevator-control installations
Compare gateway status, power and reported floor with the physical elevator. Review whether a task was cancelled and resubmitted during the elevator sequence. Building-authorized personnel and the elevator-control supplier should handle gateway access and floor calibration, followed by a complete cross-floor test.
What information helps diagnose Big Dog battery, sensor or Wi-Fi issues?
Applies to: Big Dog; battery and sensor diagnostic cases
Provide the fault time, hardware and software versions, and backend status. Evaluate overall runtime alongside battery-percentage changes. Persistent sensor or network faults require checks of the relevant connection and power supply by a technician using the installed hardware documentation. A single percentage change is not a complete battery diagnosis.
Where should I check Big Dog speed settings and repeated tasks?
Applies to: Big Dog; speed settings and route-mode application cases
Check the settings for the active operating mode and the task configuration. The recorded application configured repeated tasks under route mode. Menu availability depends on the installed application version. For unexpected speed, inspect the active state and logs before changing operating limits.
Why is the Big Dog navigation web interface unreachable after Wi-Fi connects?
Applies to: Big Dog; network arrangement described in the field record
Confirm that the computer and robot are on a network that permits communication. In the recorded arrangement, 192.168.10.* was used by the lidar network and conflicted with an external Wi-Fi subnet. Confirm the installed network plan before changing addresses.
Does an empty Big Dog rmDemo status screen mean the application is faulty?
Applies to: Big Dog; Android-to-navigation communication cases
First check whether the navigation backend is operating, then inspect Android-to-navigation serial communication. A separate case entered power-board upgrade mode after a prolonged power-button press and required the appropriate exit procedure. Identify the active state before choosing a recovery action.
Why might Big Dog docking fail with no response from the charging-station light?
Applies to: Big Dog; charging station whose main board had been replaced
The recorded case followed a charging-station main-board replacement and involved the infrared transmitter/receiver connection on the wrong port. Review the service history and station model, then have a technician check the connection against the correct wiring diagram.
