This is awesome. Although for any modern robotics project you definitely need a powerful gpu. What's the support on the board to hook up an external gpu?
For the projects where you would benefit from a GPU, you could perhaps commicate with a bigger computer that does the calculations? Too much latency for some applications of course but not for others.
If your project really needs a GPU and it needs it on the device that is controlling the robotics components, I think probably something other than the BB Blue would be more appropriate.
Wat. I know this is hacker news, but not every project requires a DNN.
