Camera

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 ?

best

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

A long shot but sometimes work, and one more thing you can try. Have you tried reseating the camera cable. Carefully remove it from the EZ-B and re-connect, insuring it's connected the correct way around. Then do the same in the camera itself.

@SteveG... That's what I suggested already... Maybe you need some coffee now too?:P

Lol. I'm picking up your bad habits now Richard, and not reading the thread fully. Going to put the kettle on now:P. Sorry @jop. One thing though, is the camera cable ok? Someone had an issue a while ago where the cable was twisted at one of the plug ends.

I took the instant coffee, bad for the stumach.

I tried to open the camera, but the wiring is a one orientation only fit as in the robot, so if the cabling is wrong its one of the cable ends having orientation wrong. Also the connection in the robot is ok.

When I started on this SLAM thing I thought ROS would be good, but there you just run into sw problems instead, so as is usual problems everywhere.

The camera may be defective. I would recommend pasting this forum thread URL into the Contact Us for warranty.

The way we can tell if the camera is working is by the blue LED on the camera flashing rapidly. Nearly a flicker... This flicker would begin within 2-3 seconds of the EZ-B being powered on.

If you see the flicker, that means the camera is functioning - however, if the data isn't being received to the PC, this might be a communication cable issue.

Worst case scenario is the EZ-B itself is not sending the video.

You can ask for an EZ-B and Camera replacement together - if that would help you feel more comfortable getting up and running. We would ask your current EZ-B and Camera to be sent back so we can investigate.

Hi DJ,

Thanks a lot for letting me get a new EZB and camera. I will post a waranty.

I can see that after power up, the flicker is absent but followed by the "slow" pulsating blue pattern, so i guess somewhing is wrong. The slow pulsating gets to a constant blue light when connecting to WiFi.

On the other hand. I am impressed by this robot toy and look forward to get some AI into its workings. I have my hands on openCV, which I hope to integrate into your API, a C++/C# combination job.

@jop ... That's the ezb... However, there is a blue led inside the actual camera case too.. As DJ mentioned it will flicker so fast it almost appears to be a solid blue....

Hi Richard,

Thanks, I never realised the blue LED in the camera case. No this is completely dark in my case, so I guess it indicates that the camera is down. No "solid" blue or flickering to be seen.
