Can Not Build Robot


I am trying to start building a robot, but the instruction view says "Completed" in the top left corner, and I am unable to proceed. I have not set up anything yet and am just exploring the platform. What can I do to resolve this issue? Has anyone else experienced the same problem?

Thank you!

It is actually prebuild from my professor and now I use it on my computer. But if the robot is connected or not does not change anything. So I think it should be no problem. The library is also up to date


what happens when you close the instruction page and reopen it ?

From the image you shared, it looks as if you have not loaded a project. Much like any other software, you will have to load a project to begin using a robot. In this case, you will be loading the JD robot. You can load the default project from either local or cloud (see image below).

For further instructions and information on using your robot, I recommend the fantastic tutorials on the EZ-Robot website. Those tutorials will show you how to build the robot, connect to the robot, and program the robot to do several things.


It seems like you might have missed loading a project in ARC, which is essential to start building and programming your robot. Here’s a step-by-step guide to get you started:

Step-by-Step Guide to Load a Project in ARC

  1. Open ARC:

    • Launch the ARC software on your computer.
  2. Load a Project:

    • Click on the Project tab at the top of the ARC interface.
    • Select Open to load an existing project. You can choose from local projects saved on your computer or cloud projects available online.
  3. Select a Default Project:

    • If you are new to ARC, you might want to start with a default project. For example, you can load the JD robot project if you have a JD robot.
    • Navigate to the Examples tab in the Open Project window and select a project that matches your robot.
  4. Add Robot Skills:

    • Once the project is loaded, you can add the necessary robot skills. For your EZ-B v4 robot, you might want to add skills like Tutorial, EZ-B Settings, and Debug.
    • Go to Project -> Add Skill and select the skills you need from the list.
  5. Connect to Your Robot:

    • Ensure your EZ-B v4 is powered on and connected to your Wi-Fi network.
    • In ARC, click on the Connection tab and select the appropriate connection method (usually Wi-Fi for EZ-B v4).
    • Enter the IP address of your EZ-B v4 and click Connect.
  6. Follow Tutorials:

    • For detailed instructions on building and programming your robot, refer to the tutorials available on the Synthiam website. Here’s a link to get you started: Synthiam Tutorials.
