Cleaning

When to Replace Parts

Page 9: Troubleshooting

Issue 1: Robot does not power on

What you see: No response when pressing the power switch. Logo indicator and screen remain off.

Likely causes: Battery fully depleted. Power switch fault. Internal hardware failure.

What to check: 1. Connect the supplied charger directly to the charging port and wait 15 minutes. 2. Check that the charger LED indicates it is supplying power. 3. Try pressing the power switch for 0.5 seconds again. 4. If still unresponsive, try a forced power cycle by holding the power switch for 12 seconds, then press again for 0.5 seconds.

Solution: If the robot powers on after charging, the battery was depleted. Review your charging schedule.

Escalate if: The robot does not power on after 30 minutes of charging and a forced power cycle. Contact HUTECH technical support.

Issue 2: Robot does not charge

What you see: Plugging in the charger or docking at the charging station produces no indicator change. Screen does not show "Charging in progress."

Likely causes: Damaged charger cable. Dirty charging contacts. Incorrect mains voltage. Faulty charging station alignment.

What to check: 1. Verify the mains outlet is working by testing with another device. 2. Inspect the charger cable for visible damage or loose connections. 3. Clean the charging electrode plates on both the robot and the station with a dry cloth. 4. If using the charging station, ensure the robot is properly aligned with the station contacts. 5. Try charging with the cable directly to rule out a charging station issue.

Solution: Replace a damaged charger cable. Clean dirty contacts. Reposition the robot on the charging station ensuring electrode plates align.

Escalate if: The robot does not charge with a confirmed working charger and clean contacts. Contact HUTECH support — the battery or internal charging circuit may need service.

Issue 3: Robot gets lost or cannot navigate to destination

What you see: Robot stops mid-route, spins in place, or returns to the start without reaching the destination.

Likely causes: Sensors blocked or dirty. Environment has changed significantly since the map was created. Path too narrow. Obstacles in the route.

What to check: 1. Check all sensors (lidar, upward/downward RGBD, camera) for dirt, smudges, or physical obstructions. 2. Clean sensor surfaces with a dry, lint-free cloth. 3. Verify the route is at least 70 cm wide with no new obstacles. 4. Check that no highly reflective surfaces (mirrors, glass walls) are confusing the lidar. 5. Confirm the destination still exists on the configured map.

Solution: Clean sensors. Remove obstacles from the path. If the environment layout has changed (furniture moved, walls added), the map may need updating by a trained technician.

Escalate if: Navigation problems persist after sensor cleaning and path verification. The map likely needs recalibration by the manufacturer technical support.

Issue 4: Emergency stop switch is stuck or not responding

What you see: The emergency stop button does not press in, or pressing it does not stop the robot.

Likely causes: Mechanical jam in the switch. Wiring fault. Switch already engaged (robot already stopped).

What to check: 1. Check if the button is already pressed in — it may need to be twisted clockwise to release. 2. Inspect the button for visible damage or debris around it. 3. Power off the robot using the power switch (hold 6 seconds) as an alternative. 4. If neither the emergency stop nor the power switch stops movement, hold the power switch for 12 seconds for a forced shutdown.

Solution: Release a stuck button by twisting clockwise. Clear any debris around the switch mechanism.

Escalate if: The emergency stop switch is physically damaged or the robot does not respond to either stop method. Cease use immediately and contact HUTECH technical support.

Issue 5: Compartment door does not open at destination

What you see: Robot arrives at the delivery location but the compartment door remains closed.

Likely causes: Incorrect compartment-to-destination assignment. Mechanical door jam. Software glitch.

What to check: 1. Verify on the screen that the correct destination was assigned to the compartment. 2. Check that the robot has fully stopped and confirmed arrival (screen should show arrival prompt). 3. Wait up to 30 seconds — the door may take a moment to trigger. 4. Check for any physical obstruction preventing the door from opening. 5. Restart the robot and retry the delivery.

Solution: Reassign the correct destination to the compartment. Remove any physical obstruction. Restart the robot if the issue appears to be a software glitch.

Escalate if: Doors consistently fail to open after confirming correct setup and restarting. Contact HUTECH technical support — the door mechanism may need repair.

Issue 6: Robot moves erratically or drifts off course

What you see: Robot veers to one side, makes unexpected turns, or bumps into obstacles despite having a clear path.

Likely causes: Dirty or damaged drive wheels. Debris wrapped around wheel axles. Sensor obstruction. Low battery affecting motor power.

What to check: 1. Power off the robot and inspect both drive wheels for debris, hair, or thread wrapped around the axles. 2. Check that the anti-collision strip is intact and not pushed inward. 3. Clean all sensors (lidar, RGBD, camera) with a dry cloth. 4. Check the battery level — low charge can cause inconsistent motor behaviour. 5. Ensure the floor surface is clean and dry with no liquid or gooey substances.

Solution: Remove debris from wheels and axles. Clean sensors. Charge the robot if the battery is low. Ensure the floor is suitable (flat, dry, free of obstacles under 2 cm that could catch wheels).

Escalate if: Erratic movement continues on a clean, flat surface with clean sensors and full battery. Contact HUTECH technical support — a motor or sensor calibration issue may exist.

Issue 7: Screen is unresponsive or frozen

What you see: Touchscreen does not respond to taps. Display is frozen on one screen. Screen is black but indicator light is on.

Likely causes: Software crash. Screen hardware fault. System overload.

What to check: 1. Wait 30 seconds to see if the system recovers on its own. 2. If the robot is moving, press the emergency stop switch first. 3. Attempt a normal shutdown by holding the power switch for 6 seconds. 4. If that fails, perform a forced shutdown by holding the power switch for 12 seconds. 5. Wait 10 seconds, then power on again.

Solution: A restart resolves most screen freezes. If the screen recovers after restart, monitor for recurrence. Clean the screen surface — dirt or moisture can interfere with touch sensitivity.

Escalate if: The screen remains unresponsive after a full restart cycle, or the problem recurs frequently. Contact HUTECH technical support.

Issue 8: Robot makes unusual noises during movement

What you see: Grinding, clicking, or squeaking sounds during travel that were not present before.

Likely causes: Debris caught in drive or auxiliary wheels. Worn wheel surfaces. Loose internal component. Floor surface irregularities.

What to check: 1. Power off the robot and press the emergency stop. 2. Inspect all wheels (drive and auxiliary) for trapped debris, hair, or foreign objects. 3. Manually rotate each wheel to check for grinding or resistance. 4. Check the anti-collision strip for loose sections. 5. Inspect the floor path for sharp debris, bumps, or uneven surfaces.

Solution: Remove any debris from wheels. If wheels show visible wear, schedule a replacement through HUTECH support. Ensure the operating surface is smooth and flat.

Escalate if: Noises persist after debris removal, or if wheels show significant wear. Contact HUTECH technical support for wheel replacement or internal inspection.

Issue 9: Battery drains much faster than expected

What you see: Runtime is significantly less than the rated 9 hours. Battery percentage drops quickly during use.

Likely causes: Aged battery. Consistently running at maximum speed. Heavy loads. High ambient temperature. Frequent door operations.

What to check: 1. Note the actual runtime from full charge to 20% under normal conditions. 2. Check the speed setting — higher speeds consume more battery. 3. Verify loads are within the 20 kg limit. 4. Check the ambient temperature is within 0-40 degrees C. 5. Ensure the robot is not repeatedly running low-battery cycles (below 20%) which degrade battery health over time.

Solution: Reduce speed to 0.8 m/s. Keep loads within rated limits. Charge before battery drops below 20%. Operate within rated temperature range.

Escalate if: Runtime is less than half the rated duration under normal conditions with the above measures in place. The battery may need replacement — contact HUTECH technical support.

Issue 10: Robot cannot dock with charging station

What you see: Robot approaches the charging station but fails to connect. Repeatedly attempts and backs away. Charging does not begin after docking.

Likely causes: Misaligned charging electrode plates. Dirty contacts on robot or station. Charging station not powered. Station position has shifted.

What to check: 1. Verify the charging station is plugged in and powered. 2. Clean the electrode plates on both the robot and the station with a dry cloth. 3. Check that nothing is blocking the station approach path (at least 1 metre clear in front). 4. Ensure the charging station has not been moved from its mapped position. 5. Try manually pushing the robot into the station, aligning the contacts.

Solution: Clean contacts. Ensure clear approach path. If the station was moved, it may need to be remapped by a technician.

Escalate if: The robot repeatedly fails to dock despite clean contacts and clear approach. Contact HUTECH technical support to check station alignment and robot docking calibration.
