Overview: To control hardware Linkbots you need either to download and install Linkbot Labs software or download and install C-STEM Studio software, which includes Linkbot Labs. Section A below has instructions for Windows and MacOS machines, and Section B has instructions for Chromebooks. Tablets are not supported for hardware Linkbots.
A. Instructions for Windows and MacOS
(1) Download and install the latest version of Linkbot Labs from the Barobo Downloads page at https://www.barobo.com/downloads. (Linkbot Labs is also included in the C-STEM Studio integrated software platform. More info here and download available here.)
(2) Launch RoboBlockly at www.roboblockly.com using a regular browser (Chrome is recommended).
(3) Connect the hardware Linkbot to the computer using either a micro USB cable or a wireless dongle, and then add the Linkbot’s ID (found on the Linkbot’s label, e.g., “ZG81”) using the Linkbot Labs sidebar on the left side at RoboBlockly, as shown in Figure 2 below. (Click on the “Linkbot Labs” arrow just below the RoboBlockly heading at the top left to open or close the sidebar, as circled in red in Figure 1.) Note that when first opening RoboBlockly it may take a few seconds for the Linkbot Labs arrow to appear.
Figure 1: RoboBlockly user interface with the Linkbot Labs sidebar closed. Click on the “Linkbot Labs” arrow, as circled in red in the image, to open the sidebar (or close the sidebar, if open).
Figure 2: RoboBlockly user interface with the Linkbot Labs sidebar open. Enter the ID for a Linkbot in the box (circled in red) and click the “Add” button.
Wndows/MacOS Instructions, continued:
(4) Drag a Linkbot instruction block such as driveDistance() to the Workspace area of RoboBlockly.
(5) Click “Run” or “Step” to move the virtual Linkbot on the grid and the hardware Linkbot at the same time.
(6) If the hardware Linkbot does not move, you may need to restart the Barobo Linkbot Service program by right-clicking on the “L” in the Windows task list at the bottom right of the screen (Figures 3 and 4 below) or clicking on the “L” in the Mac menu bar at the top of the screen (in the list of icons on the right side of the menu bar, Figure 5 below). Choose “Restart Linkbot Service” from the popup menu. (If the "L" is missing, restarting the computer should solve the problem, as the Linkbot Service is launched automatically when the computer starts. If you are using a Windows machine, an alternative to restarting is to double click the "LinkbotServiceManager.exe" program located at C:/Program Files (x86)/LinkbotLabs 2.1.x.)
