I’ve just added an Xavier to my open source four wheel drive robot. For developers, the first Xavier is $1300. I’m really interested in pure camera based navigation and the Xavier is perfect for developing something like that. I’m going to start with using a stereo camera to follow hiking trails and go from there. The latest on the robot is here if anyone is curious: https://imgur.com/a/GqXD2Zj https://imgur.com/a/GqXD2Zj

Are you having any trouble with USB and that ps4 stereo camera? I got a Xavier to process video from intel realsense 415 stereo cameras and am having a lot of USB problems with dropped frames and frames missing data. The cameras work fine on x86. The entire Xavier software stack feels very early beta quality.Not sure if I should abandon the Xavier, or try a PCIe USB card or what.

  I have not used the USB camera extensively. I installed the experimental drivers (https://github.com/ps4eye/ps4eye/blob/master/README.md https://github.com/ps4eye/ps4eye/blob/master/README.md) and got it working, then left it displaying for a couple of days. It never froze, but I wasn’t watching for dropped frames. Now I’ve mounted the Xavier on the robot, but haven’t started developing the application with it. I definitely remember that when you download the system image for the Xavier, they said it was a beta version or something like that. I haven’t seen any issues in my limited use, but I did get the sense it wasn’t fully baked. Hopefully your issues get worked out soon. It would be interesting to see how long the TX2 development took to stabilize.

  I highly highly recommend using a PCIe USB card, especially if you are using multiple cameras.

    Thank you so much, I got a PCIe USB card and it fixed all my problems.
