III. Connect Leanbot to PC Gateway for data transmission #

Step 1. Access to the Gateway #

There are 2 ways as follows:

• Option 1: Access LEANBOT – DIGITAL TWIN DEMO course on PLearn page.
  Open the lesson to perform the mission on Leanbot Digital Twin, then click on “Gateway” button on the mission screen.
  • For example, ms1 – The Leanbot moves forward, backward.
    • On the left menu, select a mission.
    • Left-click to open it.
    • Then, click the “Gateway“ button.
  • Other missions are also performed similarly to ms1.

• Option 2: Access to the Gateway

Step 2. (Only if you experience Chrome crashing) Reset permission on Chrome browser #

• Do not select Leanbot ID, because this will lead to Chrome crash
• In case Leanbot ID is selected by mistake (in step 4), please correct the mistake by following these ‘Reset permission’ steps:
  • Click on the “Lock” icon (1). For example, Leanbot ID is Leanbot 157163
  • Then click the “Reset permission” button (2)
  • Go to Step 3.

Step 3. Click the “Select Leanbot to connect” #

Step 4. Select a connection Port (for robot connected on PC via Bluetooth) #

• Select the correct Port (COMx). There are various COM ports available depending on your computer.
• Then click “Connect”.
• DO NOT select Leanbot ID. If you select it incorrectly, repeat Step 2.
• Example 1: as shown in the picture, the Port (COMx) corresponds to Port (COM4). This image is used on Chrome browser version 117.0.5938.134 or higher.

• Example 2: the port (COMx) corresponds to Port (COM6). This image is used on older versions of Chrome browser.

Step 5. Connect Leanbot to Gateway for successful data transfer #

• The Bluetooth light stops blinking when the Gateway connection is successful

• During the experience, if the robot is disconnected, the Bluetooth light on Leanbot robot is blinking, you need to reload this page and repeat steps from Step 2 to Step 5.
