Heavy-duty delivery robot for industrial material transfer, supporting up to 300 kg with delivery, cruise, and lifting modes.

Page 1: Overview

What is the T300?

The T300 is a heavy-duty delivery robot designed for industrial material transfer and large-load commercial applications. Built on a load carrier chassis with an open and flexible carrying space, it handles payloads up to 300 kg and can be equipped with different accessories to suit various transport needs.

The T300 uses both Visual-SLAM and Laser-SLAM for autonomous navigation on indoor surfaces. It features a 10.1-inch LCD touchscreen, dual 10W stereo speakers, and runs on Android. The robot supports delivery to multiple destinations with automatic route planning, cruise mode for repetitive loop routes, and — on the WTIDL1 model — autonomous lifting mode for picking up and dropping off materials without manual intervention.

With a 30 Ah battery providing 6 to 12 hours of operation (depending on load), a replaceable battery design for continuous operation, and a minimum path clearance of just 60 cm, the T300 is built for warehouses, factories, and large commercial environments where heavy material transport is a daily requirement.

Delivery Mode

Description: The primary function. Materials for multiple destinations are placed on the robot. The robot plans the optimal route, delivers items to all assigned destinations in sequence, and automatically returns to the standby point when finished.

Steps: 1. Place materials on the robot's carrying surface. 2. Use the touchscreen to assign delivery destinations. 3. Assign multiple destinations if needed — the robot optimises the route automatically. 4. Tap Start to begin the delivery run. 5. The robot navigates to each destination in sequence. 6. At each stop, the robot pauses for material unloading. 7. After all deliveries are complete, the robot returns to its standby point.

Best use case: Warehouses, factories, and commercial facilities where materials need to be delivered to multiple points in a single run.

Cruise Mode

Description: The robot follows a pre-set path in a continuous loop, pausing at designated stop points along the route for loading or unloading.

Steps: 1. Configure the cruise route and stop points in the system. 2. Start cruise mode from the touchscreen. 3. The robot follows the loop route continuously. 4. At each configured stop point, the robot pauses for a set duration. 5. Load or unload materials during each pause. 6. The robot continues to the next stop point automatically.

Best use case: Repetitive transport circuits in warehouses and factories where materials move along the same path regularly.

Lifting Mode (WTIDL1 Model Only)

Description: The robot autonomously picks up and drops off materials at configured points without manual handling. This mode is only available on the WTIDL1 model and is not supported on the WTID01.

Steps: 1. Configure lifting points and drop-off points in the system. 2. Place materials precisely at the designated lifting point in the correct orientation. 3. Start the lifting task from the touchscreen. 4. The robot navigates to the lifting point and automatically identifies the materials. 5. The lifting mechanism engages and picks up the materials. 6. The robot transports the materials to the configured drop-off point. 7. The robot unloads the materials at the destination.

Best use case: Automated material handling workflows where human intervention at pickup and dropoff should be minimised.

Important notes for lifting mode: - Confirm the robot is the WTIDL1 model before attempting to use this mode. - Materials must be placed precisely at the designated lifting point in the correct orientation. - The lifting mechanism area must be free of debris or obstructions. - Test with lighter loads first when configuring new lifting points.

Cleaning

When to Replace Parts

Page 9: Troubleshooting

Issue 1: Robot does not power on

What you see: Holding the power switch for 3 seconds produces no response. Indicator light and screen remain off.

Likely causes: Battery fully depleted. Battery not connected properly. Power switch fault.

What to check: 1. Connect the supplied charger directly to the charging port and wait 15-20 minutes. 2. Confirm the charger is receiving mains power (check the outlet with another device). 3. Attempt to power on again by holding the power switch for 3 seconds. 4. If still unresponsive, power off, open the battery compartment, and check that the battery power connector is firmly seated. 5. Reconnect the battery connector, close the compartment, and try again.

Solution: If the robot starts after charging, the battery was depleted. If the connector was loose, reseat it. Establish a regular charging routine.

Escalate if: The robot does not respond after charging and verifying the battery connection. Contact HUTECH technical support — the battery or internal power system may need service.

Issue 2: Robot does not charge

What you see: Plugging in the charger or docking at the charging pile produces no indication of charging on screen or indicator light.

Likely causes: Damaged charger or cable. Dirty charging contacts. Mains power issue. Charging pile misalignment.

What to check: 1. Verify the mains outlet is live by testing with another device. 2. Inspect the charger cable for visible damage. 3. Clean the charging port and charging electrode plates with a dry cloth. 4. If using a charging pile, ensure the robot is properly aligned with the pile contacts. 5. Try the direct charger cable to rule out a charging pile issue.

Solution: Replace a damaged charger. Clean dirty contacts. Reposition the robot on the charging pile.

Escalate if: Charging does not start with a confirmed working charger and clean contacts. Contact HUTECH support for battery or charging circuit inspection.

Issue 3: Robot gets lost or stops mid-route

What you see: Robot halts during a delivery, spins in place, or fails to reach the destination.

Likely causes: Dirty or blocked sensors (visual, lidar). Environment changed since map creation. Path narrower than 60 cm. New obstacles in route.

What to check: 1. Power off the robot and inspect all sensors (lidar, RGBD, front and top cameras) for dirt or obstructions. 2. Clean sensor surfaces with a dry, lint-free cloth. 3. Verify the route is at least 60 cm wide throughout. 4. Check for new obstacles, reflective surfaces (mirrors, glass), or changes in the environment layout. 5. Ensure the floor is clean and dry — liquid or debris on the floor can interfere with navigation.

Solution: Clean all sensors. Remove obstacles from the route. If furniture or walls have been moved, the facility map may need updating by a trained technician.

Escalate if: Navigation issues persist after sensor cleaning and path verification. Contact HUTECH support for map recalibration.

Issue 4: Emergency stop switch does not work

What you see: Pressing the emergency stop switch does not halt the robot.

Likely causes: Switch already engaged and needs releasing. Mechanical fault. Wiring issue.

What to check: 1. Check if the button is already depressed — twist it clockwise to release and try pressing again. 2. Inspect the button for visible damage or debris. 3. As an alternative, tap the screen to pause the task. 4. If neither method works, hold the power switch for 3 seconds to initiate shutdown.

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

Escalate if: The emergency stop switch is damaged or non-functional. Cease operating the robot immediately and contact HUTECH technical support. This is a critical safety component.

Issue 5: Brake switch not engaging or releasing properly

What you see: Wheels do not lock when the brake is set to ON and the robot is powered off. Or the robot cannot be pushed when the brake is set to OFF.

Likely causes: Brake switch mechanism fault. Debris interfering with the switch. Drive wheel issue.

What to check: 1. Confirm the brake switch is fully toggled to the correct position (ON or OFF). 2. Power off the robot and test: with brake ON, try pushing gently — wheels should resist. With brake OFF, the robot should roll freely. 3. Inspect the brake switch area for debris or damage. 4. Check that the drive wheels are not blocked by foreign objects.

Solution: Ensure the switch is fully engaged in the desired position. Remove any debris around the switch or wheels.

Escalate if: The brake switch does not engage or release properly after inspection. Contact HUTECH support — the brake mechanism may need replacement.

Issue 6: Robot moves erratically or drifts

What you see: Robot veers to one side, makes unexpected turns, or collides with objects despite a clear path.

Likely causes: Dirty or worn drive/auxiliary wheels. Sensor obstruction. Uneven load distribution. Low battery. Wet or uneven floor surface.

What to check: 1. Power off the robot and inspect all wheels for debris, wear, or damage. 2. Clean all sensors (lidar, RGBD, cameras, collision sensor) with a dry cloth. 3. Check that the load is evenly distributed across the carrying surface. 4. Verify the battery level is adequate (above 20%). 5. Examine the floor for wet patches, debris, or uneven sections along the route.

Solution: Clean wheels and sensors. Redistribute the load evenly. Charge the robot. Ensure the floor is dry, flat, and smooth.

Escalate if: Erratic movement continues under proper conditions with clean wheels and sensors. Contact HUTECH support for motor or sensor calibration.

Issue 7: Screen is unresponsive or frozen

What you see: Touchscreen does not respond to taps. Display is frozen. Screen is black while 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. 2. If the robot is moving, press the emergency stop switch first. 3. Hold the power switch for 3 seconds and tap "Power off" if the screen responds. 4. If the screen does not respond, hold the power switch longer until the robot shuts down. 5. Wait 10 seconds, then power on again.

Solution: A restart typically resolves screen freezes. Clean the screen surface as dirt or moisture can impair touch response. If the issue recurred after a specific task, note the conditions for the support team.

Escalate if: The screen remains unresponsive after restarting, or freezes recur frequently. Contact HUTECH technical support.

Issue 8: Battery drains much faster than expected

What you see: Runtime significantly shorter than rated (12 hours no load / 6 hours max load). Battery percentage drops rapidly.

Likely causes: Heavy or maximum load. High speed setting. Aged battery. Frequent start-stop cycles. Extreme operating temperature.

What to check: 1. Record actual runtime from full charge to 20% under your operating conditions. 2. Check the current speed setting — higher speeds consume more power. 3. Weigh the typical payload — closer to 300 kg means closer to 6-hour runtime. 4. Verify the operating temperature is within 0-40 degrees C. 5. Check how often the battery has been run below 20% — repeated deep discharges degrade battery health.

Solution: Reduce speed if possible. Keep loads within rated limits. Maintain a regular charging schedule that avoids deep discharge. Swap to a fresh battery if the facility has spares.

Escalate if: Runtime is less than half the expected duration for your load conditions despite following all guidelines. The battery may need replacement — contact HUTECH technical support.

Issue 9: Lifting mode not working (WTIDL1 only)

What you see: Robot does not lift materials at the configured lifting point. Lifting mechanism does not engage. Materials are dropped during transport.

Likely causes: Wrong model (WTID01 does not support lifting). Lifting points not configured correctly. Materials not positioned properly at the lifting point. Mechanical fault in the lifting mechanism.

What to check: 1. Confirm the robot is the WTIDL1 model (check the label or settings screen). 2. Verify that lifting points and drop-off points are correctly configured in the system. 3. Ensure materials are placed precisely at the designated lifting point in the correct orientation. 4. Check that the lifting mechanism area is free of debris or obstructions. 5. Test with a lighter load to rule out overweight issues.

Solution: Reconfigure lifting and drop-off points if they were set incorrectly. Reposition materials at the lifting point. Clear any obstructions from the lifting mechanism.

Escalate if: The lifting mechanism does not engage or makes unusual sounds. Contact HUTECH technical support — the lifting hardware may need servicing.

Issue 10: Robot cannot dock with charging pile

What you see: Robot approaches the charging pile but fails to connect. Repeatedly attempts and reverses. No charging indication after docking.

Likely causes: Dirty charging electrode plates. Pile misalignment. Pile not powered. Approach path blocked. Pile location has changed since mapping.

What to check: 1. Verify the charging pile is powered and active. 2. Clean the electrode plates on both the robot and the pile with a dry cloth. 3. Ensure the approach path is clear for at least 1 metre in front of the pile. 4. Check that the charging pile has not been moved from its mapped position. 5. Try charging with the direct charger cable to verify the robot's charging circuit works.

Solution: Clean contacts. Clear the approach path. If the pile was relocated, have a technician update the map.

Escalate if: Docking consistently fails despite clean contacts and a clear path. Contact HUTECH support for pile alignment check and robot docking calibration.

Page 10: Frequently Asked Questions

Charging and Battery

How long does the T300 take to charge? About 2 hours to reach 90% using the supplied charger (29.2V, 15A output). It supports both direct charger connection and a charging pile (docking station). Tap "Return to Charging" on the interface and the robot navigates to the pile automatically.

How long does the battery last? 6 to 12 hours depending on load. With no load, approximately 12 hours. At maximum load (300 kg), approximately 6 hours. Actual duration depends on speed setting, load weight, route complexity, and environmental conditions.

Can the battery be replaced? Yes. The T300 has a replaceable battery in an accessible battery box. Power off the robot, open the battery compartment, disconnect the power connector, remove the battery, insert a replacement, reconnect, and close the compartment. This allows continuous operation by swapping charged batteries.

When should I charge the robot? When the battery level drops below 20%. Running on low battery for extended periods reduces overall battery lifespan. Maintain a regular charging schedule during breaks in operation rather than waiting for the battery to fully deplete.

Operation
