🕮Note

When modifying a map, in addition to expanding the map, you can also change the functions supported by the robot, the pick-up locations, the greeting locations, etc. Move the robot to the start point (startup location) before you start expanding the map. After the expansion is completed, return the robot to its start point. Otherwise, the map expansion will fail.

This section takes creating new maps as an example and assumes that ceiling markers are used for positioning. Please refer to 3.1 Mapping Instructions for the application requirements of ceiling markers.

Operational steps

Step 1 Select Edit Map in the Settings > Map Settings interface and enter the authorization code.

The Edit Map interface is shown below.

Step 2 Move the robot to a position right under the ceiling marker.

Step 3 Tap New Map, select Positioning on the Ceiling and then tap Next.

The Mapping interface is shown below, where you can set a start point as the startup location for the robot.

If you need to set more than one start point, you may place the robot under a different ceiling marker and tap Add the start point.

Step 4 Move the robot along the desired route, which will be recorded by the robot.

When the route recording completes, return the robot to the start point before tapping Finish Mapping.

Caution

• During mapping, the operator must always stay behind the robot to ensure that the Lidar will not be blocked to avoid error when traveling for a task.
• To ensure mapping accuracy, make sure that the robot travels in the middle of its path and moves along the mapping route at least twice.

Step 5 Tap Next and scroll to select the functions that you need the robot to support, such as customer attraction and guiding. Please select the functions according to your actual needs.

Temporary stop point	A temporary docking location has to be set up for an actual scenario where more than one robot works together. The robot may go to the temporary stop point when the pick-up location is occupied, and it will go to the pick-up location when the location is available. Ensure that the temporary stop point is more than 1 m away from the pick-up location.
Function Location	Description
Charging pile	Users who have purchased a charging pile can set up the charging pile location. Move the robot to a position 0.4 -1.2 m (1.3-3.94 ft) in front of the charging pile and face it to the pile. Otherwise, the charging pile location may fail to be set up.

6 Docking Instructions

KettyBot supports three docking modes. In actual scenarios where multiple robots cooperate, users can select any docking mode during mapping. This section only covers the description of the three docking modes. For details about mapping, please contact our technical engineers.

Three docking modes:

• One-to-one Docking mode: Each robot has its fixed pickup location (docking location).
• Free Docking mode: Set multiple pickup locations (docking locations) for the robot to dock by priority, i.e., the robot chooses the nearest pickup location for docking.
• Waiting mode: Set temporary docking location. When the robot has no task and there's no vacancy at the pickup locations (docking locations), the robot docks at the temporary docking location. Once a vacancy appears at a pickup location (docking location), the robot automatically goes there for docking.
