Note: The indicator light of the charging pile will be on in two colors only as follows:
Red: The charging pile has been electrified, but unconnected to equipment for charging.
Green: The charging pile has been electrified and connected to equipment for charging.
Special note: Improper operation of the battery may cause accidents such as battery explosion, fire, liquid leakage, and corrosion.

ENVIRONMENTAL SURVEY

The use site of the robot is only an indoor environment with a flat layer and no drop. In view of the situation that the sensor has a blind area and different materials will interfere with the sensor to some extent, the scenes where the equipment can operate stably and the dangerous scenes are listed below. Before the equipment enters the site, it is necessary to determine whether it is suitable for equipment operation through corresponding surveys.

1. The equipment can only be operated in an indoor environment.
2. The operation site mustn’t have dropped, and there is no height difference of more than 10mm on the same plane in the environment.
3. If there is a slope in the operation site, it must be within the range of the specification value. In addition, it is not recommended to deploy points near ramps.
4. When there is a lot of glass in the use environment, such as glass walls, glass doors, etc., the shielding stickers provided by our company should be pasted at the lidar height of the glass environment.
5. If there are frequent decorations or environmental changes in the operation site, the map should be rebuilt in time to avoid the risk of map offset during equipment operation(the risk areas include but are not limited to fire stairs, leveling stairs, and small steps, and escalators).

3.1 Risk of Falling

1. When a site has a drop that is 10mm lower than the ground or in a non-planar environment, there will be a risk of falling and overturning when the equipment is moving.
2. When deploying in a site with a risk of falling, environmental safety judgments should be made in accordance with the Survey Specification for Deployment of Self-developed Chassis, and statistics should be reported through the Basic Leveling Deployment Survey Document.

3.2 Network Communication

1. Simply check whether there is a blind spot in the network signal of the mobile phone card on the spot. If the mobile robot is in the signal area, it may cause the machine to go offline.
2. If Wi-Fi is available on site, check whether it is necessary to connect to an account or obtain a verification code. If this is the case, it may cause the machine to fail to verify and go offline.

3.3 Deployment Area

1. Deployment area: The deployment area should be smaller than the device mapped area.
2. Check whether the on-site environment has fenced decoration because the scene change requires rebuilding the map. Therefore, if there is a fenced area, you need to inform the client clearly in advance(as shown below).

3.4 Ground Type

1. Fill in according to the type of on-site ground (as shown below).

3.5 Ground Survey

(1) Check whether the ground contains any landmark light. If the landmark light is too high, the machine may shake(as shown below).| (2) Check whether there are too many temporary obstacles on the ground, as this will cause the machine to shift(as shown below).
---|---
|
(3) Check whether there are downward, upward steps, or stairs in the environment. This item is very important as the machine may fall over if there are downward stairs or steps, where it is generally not recommended to deploy(as shown below).| (4) Check whether is a continuous large gloss in the operating environment. If yes, it needs to be filmed, or else the safety of the machine can’t be guaranteed(as shown below).
|
(5) Check whether there are steps with a height difference greater than or equal to 10mm or slopes greater than 5° in the environment. There are risks in the operation of machines in such an environment, and deployment is not recommended(as shown below).| (6) Check whether there is any normally open or normally closed safety door in the environment. Generally, there are upward and down-ward stairs inside the safety door, which is also an area with a risk of falling(as shown below)
|
(7) Check whether there are pits and ridges with a height difference greater than or equal to 10mm in the environment (as shown below).|

3.6 Carpet
Type If there is any carpet, it is necessary to check its material and thickness. Too thick carpet will cause a height difference between the charging contacts of the robot and the charging pile, resulting in the inability to align or return to the charging pile(as shown below). 3.7 Corridor
Check the minimum width of the corridor front, back, left, and right(as shown below). 3.8 Risk of Falling
When there is a falling environment, it is not recommended to move the equipment on-site if it is not equipped with a top-view camera. When a top- view camera is installed, environmental surveys must also be carried out in accordance with section 2 and reported.

1. Stairs (downward), escalators (upward and downward).
2. Steps with a drop of 10mm or more.
3. An environment with a high slope (above 5°, non-friction ground slope) or a high ridge (above 10mm).
4. Fire safety passage (normally open/normally closed door): behind the door, there are falling environments and fire stairs.

3.9 Map Offset Risk
You need to set a security threshold during deployment. After the map building, let the robot walk around the working area and check the matching value. Set the security threshold to the lowest value of the circle below 10% for Movement.

Environmental reasons:

1. When there is a carpet with a thickness of more than 0.5cm in the on-site operating environment, there is a greater probability that the map will shift.
2. When used in an icy, frosty, or slippery environment, there is a greater probability that the map will shift.
3. When the operation site is open in a large area and moves in the area with no reference object that exceeds the laser recognition range, there is a probability that the map will shift.
4. The environment in the operating site has changed significantly compared with the last time the map was created: such as re-decoration, if the map is not rebuilt after the layout change, there is a greater probability that the equipment map will shift.
5. Operation in the complex venues: If there are many mobile tables and chairs in the office and frequent changes are made, there is a greater probability that the equipment map will shift.
6. When the site environment has slopes, ridges, or ditches, and the equipment speed is fast, there is a greater probability that the equipment map will shift.
7. Obstacles can’t be recognized by the sensor when moving: If the top-view camera is not installed, there are obstacles that are higher than the ground and lower than 23cm and cause bumps and scratches, there is a greater probability that the equipment map will shift.
8. It needs to be started on the charging pile or contact the charging pile before formal use.

Operational reasons:

1. When correcting the position with the wrong tool or interface, there is a greater probability that the equipment map will shift.
2. After the equipment is turned off, it is pushed to another location, and it is rot turned on in the charging state.
3. The equipment is charged/ turned on at the charging pile, but the position of the charging pile does not match the actual position.
4. The wheels move off the ground when the equipment is turned on.
5. Push and drag the equipment for a long time to move when it is not in emergency stop after being turned on

3.10 Risk of Collision

1. No top-view camera installed: Obstacles 23cm below the ground. A top-view camera installed: Obstacles 8cm below the ground.
2. Objects with reflective, light-absorbing, and transparent materials.
3. Objects with a visible volume less than 2cm or protrusions less than 2cm.
4. When the overall height of the equipment is over 1.1m and no additional configuration is made, it may collide with objects higher than 1.1m and lower than the height of the equipment.

3.11 Marking in the Map

1. The virtual wall must be calibrated inside the site where the equipment does not enter in order to avoid accidental entry.
2. If the map building range is larger than the actual operating range of the equipment, try to make the virtual walls enclose the actual operating range to avoid excessive movement of the equipment due to map offset.
3. If there is a dangerous area, the virtual walls should be at least 0.5m away from the dangerous area.
4. If the object is actually in the scene and the radar can scan it, but the part is missed in the actual scan, it needs to be complemented with the forbidden area.
5. In the glass environment, such as glass walls, glass doors, etc., the area needs to be marked with virtual walls.
6. At a three-dimensional obstacle higher than the scanning height of the radar, the area needs to be marked with virtual walls.
7. At low obstacles, such as ridges, pits, and carpet areas that do not meet the performance parameters of the chassis, the area needs to be marked with virtual walls.
8. Strong light interference area: if the surrounding lights is particularly strong.

PRECAUTIONS FOR MOVEMENT

1. Flatness requirements: The road for the robot should be smooth and free of bumps, steps, and corners.
2. Slope: The robot should move on the ground with a slope less than 5° to avoid the risk of overturning.
3. Joint: Avoid joints (grooves should be less than 40mm) in the walking path of the robot as far as possible, and wider joints should be treated with cover panels.
4. The load-bearing capacity of the ground: The load per unit area of the ground must be higher than the load per unit area in the horizontal projection area of the robot, and the stress generated by the robot while walking on the ground should be effectively transmitted to the load-bearing layer.
5. The friction coefficient of ground: The friction coefficient of ground should not be less than 0.5, to ensure safe braking distance and positioning accuracy.
6. Requirements for the cleanliness of the ground: There should be no slipping liquids such as water spots and oil stains on the ground, to prevent the robot from slipping and thus affecting its operation. The road surface within the walking path of the robot must be kept clean, and there should be no debris or obstacles that may prevent the driving wheels from passing smoothly.
7. Avoid objects that are too low or suspended in the forward direction, because they may affect the detection function of laser sensors and other devices.

ROUTINE MAINTENANCE

5.1 Maintenance of robot

1. The surface of the robot shell should be protected from collision, scratching by hard objects, impact, and washing with a lot of water.
2. Only clean the surface with a soft damp cloth.
3. The working environment of the charger should be dry and clean.

COMMON FAULTS AND CONTACT INFORMATION FOR AFTER-SALES SERVICES

Security thresholds need to be set when deploying. After the map is built and repaired, the robot is allowed to walk around and detect the matching value. The security threshold needs to be 10% lower than the matching value.

6.1 Common faults and solutions
Simple and non-technical solutions are shown below. Please contact the after- sales service hotline below if the fault cannot be removed in the following manner.

Start fault:

1. Check whether the robot has been turned on and whether the main power switch at the chassis of the robot has been turned off. If the main power switch has been turned off, please turn it on to start the robot normally;
2. If the power switch has been turned on but the robot cannot be started, the battery of the robot may have run down, please return the robot to the charging pile for charging.

Failure to operate according to the set route

1. Check whether there are major layout changes in the operating environment of the robot; The robot is able to judge its position by recognizing the feature values of objects in the environment in the process of automatic navigation. Therefore, the robot is unable to position correctly when the environment changes greatly, and a new map needs to be built for the robot at this time.
2. Check whether the position of the charging pile of the robot has been moved; The robot needs to calibrate the map based on the position of the charging pile. If the position of the charging pile is moved, it needs to be recalibrated on the configuration page of the chassis.

Control failure

1. If the network signal is too poor, please check the network status of the environment where the robot is located;
2. If the chassis system of the robot fails, please contact after-sales technical support;

Failure to walk normally

1. The power is low, please push the robot back to the charging pile for charging;
2. The Robot network fails, and it is unable to connect to the Internet normally;
3. If the chassis of the robot fails, please contact after-sales technical support;

Charging failure
Park the robot on the charging pile again, and check whether the charger is in a normal state: the power indicator turns red (the power is on, but no robot is connected), or it is flash-ing in green (the robot is being charged); if the robot still cannot be charged, please contact after-sales technical support.
