Is the ezb fitted securely in the chassis? It may have come loose and disconnected. Press it back in.

When the power switch is moved to the on position, and the ezb is getting power, the audiable chime will be heard. Also the ezb will flash its led based on the wifi mode.

If the ezb is not getting power, perhaps it is not securely inserted into its compartment in the chassis.

Have you checked the fuse?

Where do I buy a new fuse for him? Also it didn't show any signs it was blown. Also DJ Sures what am checking? The EZB? Where is that

The roli robot was assembled using ezbits. The instructions to build the robot would have been viewed in the learn section of this website. That can be accessed by pressing the learn menu option at the top of this website.

It may be important to revisit the build instructions to refresh your memory of what you learned during building the robot.

The ezb is the computer that all the wires connect to. You would have inserted the ezb into its place in the chassis during the build process.

The ezb gets its power from a connector at the bottom of its unit. That connector makes a connection with the matching connector in the roli chassis.

If the ezb is loose (which may happen over time and during transport), you will have to gently press it securely into place.

Here is a direct link to the ezb overview within the roli learn course for convenience: https://synthiam.com/Tutorials/Lesson/12?courseId=3

Thank you all I got him fixed it was the fuse. I just need to get his servo motors working
