True, an extension cable would be good in some of my other robots, but BB-8 is particular tricky because his head floats on the outside of the body unit and has no way of having a physical connection for wires. Thats why the wireless camera is so important to the design, or as Jeremie pointed out using the IoTiny+Camera in the head and in ARC connecting that controller with the body controller to share information. Not quite sure how to go about designing the overall system for the two controllers to talk or at-least have the head take commands from the body unit. I might start a new thread to discuss figuring out the controller system.

Arc can connect to 255 different ezb controllers at the same time. One of your controllers can be in the head for the camera. The other can be in the body for the rest

I suggest using an io tiny for the head and a regular ezb for the bottom part so you dont have to worry about much

DJ Sures you can use the ezb camera on the ezb v3?!

You cannot use any camera with the ezrobot ezb v3

Actually who uses the ezb 3 anymore

Ez robot made the v4 because it was better in every way

Even the io tiny puts the v3 to shame
