• RAE

  • RAE cameras not connecting

the issue seems to have been the cable; I'm now able to SSH into the robot using the cable. Hooray!

The commands you suggested to stop robothub-ctl also works, and now when I launch the launch file, it doesn't give errors about acquiring the camera devices. Hooray x2!

However, I'm still unable to view images from the robot on my own machine. that's because the robot's subnet (192.168.197.x) doesn't match my wifi network's (192.168.1.x). ROS2 doesn't support connections between robots on different subnets. I can think of two ways to fix this - 1) get RAE to connect to my wifi (without using robothub), which is something I want to do eventually anyway, 2) change the robot's IP address while connected over wifi so the subnet matches. Do you have advice on how to do either or both of these?

Thanks!

    I've recently seen a similar error from the initial post. Reboot helped.

    However, I wonder if there's a command that allows to force release all the devices.

      sskorol I wonder if there's a command that allows to force release all the devices.

      I agree on this point.

      robothub-ctl stop is not sufficient.

        Newbee here, bough RAE to give to my children to play but its more complicated than expected(thinking will have an friendly android app), All connected and working with Robohub. I can move the robot and change colors of LED. Now I have some questions:

        • have no video streaming, should I install additional app or run some commands trough SSH

          edit: started streaming by itself, so now it is working…

        • the robot is not going straights, it drifts to the left

        • not sure how to use follow me option and "Edit face" is doing nothing.

          We are working to make rae more accessible with new updates.

          • try using chrome if you have not. I found things work as better on chrome.
          • that happens when using the manual control?
          • Does preview show? Sometimes the follow-me mode won't work unless there is image preview showing as well.

              yes I use Chrome

              when using manual controls it's the same (pressing the forward arrow but going in a left curve)

              after several tests each time is different. Follow me works, but it's hard to follow because it can't go in a straight line. Sometimes both cameras stream, sometimes only the rear, and sometimes neither.

              Great, my son is 6 years old and he really enjoys the robot!
