Hi,
I just got a Roli robot for some SLAM experiments, but the camera does not work. I was trying the tutorial with the red ball that should be tracked, but the camera showed up as disabled in the on screen log.
The camera is plugged into the EZ-B board in the only correct manner there is possible.
Please, do you know what could be wrong ?

@Jop.
Have you tried closing the project and opening up again to see if the camera initiates?
Hi Steve,
Thanks for your comment. Yes, I tried to close the ARC application while the robot was still on, but no success. I don't know how to close the project as such.
More and more I suspsect that the camera must be at fault. I am happy with the robot as such and it would do a perfect job at mapping its surroundings, but it needs the camera to see.
job, are you able to use the USB camera on your laptop?
Hi DJ,
Thanks for helping me on this. I don't use a laptop, but a HP desptop. Yes the camera works on the desktop and also in the ARC app, I just saw my own semi-nice face in ARC.
I don't have a USB camera, but a built in camera, a web-cam.

So you think it could be a communications problem between the camera and PC ?
Could be. I actually have slow mini-laptop and could run the stuff there. I will report back.

Exactly the same behavior on my acer mini-laptop, actuators work but not camera.
jop, Try deleting the camera from your project, then add it again. In ARC choose Project, add, camera, camera device, start camera. Steve S
Hi Steve S.
Thanks for joining the discussion.
I tried to delete camera by closing the camera window and then adding it again by your method. The logs still show camera disconnected. I think the camera itself is the problem.
