I have so far purchased so far the Jetson TX2 and a collaborative robot arm from UFACTORY (https://www.kickstarter.com/projects/ufactory/ufactory-lite-6-most-affordable-collaborative-robot-arm) This arm was the prefect choice for price and weight capacity (1kg). It also features a built in controller and runs on 24volts. 

I have the Jetson TX2 and have run benchmarks and I'm attempting to pipe the onboard camera to a OpenCV program. I also have a older version 1, ZED camera for the main stereo vision.
