Very interesting.  Thanks for sharing, could be an option on the rover.

I found myself looking at a Coral board a few weeks ago.  I can't get clarity on it as I haven't decided on what the main camera will be yet, still thinking about the OAK-1 or OAK-D.

I think I am taking a bottoms up approach on this bot, focusing on the MCU side first and using a small Pi for now, as I am building an entirely new code base for this bot.  In the past I recycled a lot of code from prior bots, a lot of rust / unused code can accumulate so I am trying to go clean slate.  By the time I get to higher functions like object recog and models, hopefully the choice of SBC and cams will be clearer or even better tech will have come out.

From my perspective, having used/programmed an OAK-D for a few months and researched things like TinyML, TFLite, etc., I think it comes down to if you have an ML pipeline/framework you like vs. others.

They're all trying to get in as the device you stick at the head of your image/vision-processing pipeline(i.e., on your robot), but Coral vs. OAK-D is really about TensorFlow and Google's TPU vs. OpenVINO and Intel's

Movidius platform. There are tools in both systems that will let you take a larger, pre-trained CNN like ImageNet or YOLO and convert it into something that will run on on of these smaller platforms and if you're happy with

pre-trained 'nets, that's fine.  If, on the other hand, you have a lot of time & tooling invested in Tensorflow(for example), it's going to be a lot easier to run your TF model on a TPU-based board like the Coral.

HTH,

That is great info, kinda makes me want to try the Coral path more.

For a time, I ran a Latte Panda Alpha 864 on one of my bots, and a Movidius 2 Stick.  It was fairly easy to get the Movid stick going, although I felt like intel could make their whole system even easier to use.  I eventually phased out the Movid stick as it was slower than the Alpha for running most of the models I was trying...unless I had the Alpha tied up doing something else.  I hope they will come out with more/faster Movid sticks.

Hey All,

   Noticed that the Coral AI page had been updated for the Dev Board Micro

and at least one vendor was taking pre-orders.
