device connection

• Internet cable connection —it is used to download the data, one end connects to the device, and the other end connects to the computer;

• Power button -it is designed to power on the lidar system;

1. insert one or two batteries into the battery compartment;
2. connect one end of the main cable to the laser scanner, and the other end to the battery compartment;

Install the GNSS antenna
Push the GNSS antenna base plate to the slot, and insert the antenna cable into the port;

Notes: It is better to remove the GNSS antenna carefully, not to rotate the antenna cable;

Install the panorama camera (it is an optional part)

Press the lock button with the left hand, and push the camera to the camera slot with the right hand; the same method is to uninstall the camera.

Notes: Please remove the panorama camera carefully so, as not to hurt the laser scanner in front.

Data capture

1. Connect the battery and the main cable with the battery compartment;
2. Press the power button and the LED light is on;
3. Long Press the camera power button, and the camera is on;
4. Go to the start point, put the instrument on the ground(flat ground)；
   • Press the start recording button, the scanner starts scanning
   • The camera will start recording too at the same time or after a few seconds
5. After starting the scan, please keep the instrument in one place without moving for 1 minute or so, and then get up and start scanning;
6. when finishing the scan, keep the instrument in the same place without moving for 1 minute too, and then press the start recording button again to stop the scan.

Notes:

1. When initializing, don’t move the instrument;
2. Keep the instrument in front of the operator in the canning process.

Data download and RTK function settings

Data download
Connect the LiDAR system with the computer via a network cable:

Copy out the data folder, all the information is in the same folder.

RTK settings
Before using the RTK function, please insert a SIM card first,

Method 1 – Set RTK with the RobotSLAM engine software in the computer

Method 2 Using  the mobile phone APP-RobotSLAM Palm

1. Connect the device wifi to the Android system mobile phone; the password is 12345678;
2. Run the software RobotSLAM Palm and make sure to connect the device already;
3. Set the RTK information, and if next time, you want to log in to a new RTK information, please log out of the old one, and then input the new information.

Control the RobotSLAM via Palm software

• Click the arrow button to enter the interface to control the device,

Activate the device
Please get the activation code from the factory, connect the mobile phone’s WIFI, and then input the code to activate it;

RobotSLAM Engine software installation

The postprocessing software is RobotSLAM Engine Before starting processing, there are two software to install,

Apply for a software license

1. send the factory your machine code to apply a license file:
2. click “BROWSE” to import the license file and click ACTIVATE;

Data processing in RobotSLAM Engine

• 1st, Double click to run RobotSLAM Engine software,
• 2nd, Open SLAM Manager, and click” CHANGE” to load the project folder;

3rd, if the scanning time is less than 20 minutes, directly click “Run Bag file”

4th, wait for the processing, when the processing bar reaches 100%, and shows “Finish refining trajectory”, the processing finish.

5th, Export point cloud by clicking the following icon:

6th, and then click “OK” to export the point cloud.

Export colorized point cloud
If the data also collects video with the panorama camera, check ”Colorize Smooth Pointcloud” or “Colorize Origin Pointcloud” to export the point cloud, and then click OK.

Export Absolute Coordinates

1. If marks GCPs in the scanning process

If some Ground Control Points are marked and get the coordinates file for the GCPs, please check” Transform Point Cloud” and “Use GCP points” to receive absolute coordinates;

If RTK access to the CORS network during the scanning process
If the RTK function works and the GNSS solution is Fixed most of the time, before the processing, please check “Use GNSS Factor”,

When exporting point cloud, please check the following:

Battery

RobotSLAM includes two batteries, one battery can work for 2hours, and two batteries totally can work for about 4hours.

Usage Guidelines

This chapter will talk about guidelines for how to use RobotSLAM to receive desirable surveying results. As we know, SLAM can work both indoors and outdoors and doesn’t rely on satellite signals to do the scanning and get a 3D point cloud. But it doesn’t mean we can scan randomly to get the results. And some rules need to be taken care of.

Walking Speed

1. The scanning speed is normally walking speed;
2. Don’t shake the device violently during the process. When turning, turn around slowly, especially for indoor environments or stairs scanning.

Loop closure
The operator must start scanning and end scanning in the same position to close the loop. Because there are cumulative errors in the SLAM scanning, the loop works well to eliminate the error.

indoor scanning

1. For indoor environment scanning, please open all doors in advance;
2. Plan walking route;
3. Avoid walking people as much as possible;

FCC Caution

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

FCC RF Exposure Information and Statement The SAR limit of the USA (FCC) is 1.6 W/kg averaging over one gram of tissue. Device types: This device has also been tested against this SAR limit. This device was tested for typical body-worn operations with the back of the This device kept 0mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain a 0mm separation distance between the user’s body and the back of This device. The use of belt clips, holsters, and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and should be avoided.
