The Kinect utilizes an IR pattern projector and an IR camera to analyze the pattern deformation to generate the depth map of the environment. This is great for an indoor environment with constant light and no windows, however try using a Kinect outside and all of a sudden you have a normal RGB camera with very close to no depth detection. The Kinect has a max distance of 4m(~13ft).

Yes, I am well aware of that, having used them extensively since their release for the exclusive purpose of robotics. It's what makes them so dang cheap.

While I don't gamble out of principle, I would wager a rather large sum of money that the 2016 FRC game will, in fact, happen indoors, although I have to agree that polycarbonate is a nuisance.
If this years game happens outdoors I'll eat my hat and post progress pics.

Running rather well optimized SLAM code with the Kinect (and an Xtion Pro) on the ODROID U3 nets between 5 and 15 FPS. I imagine I could get it higher but I have other projects I need to work on. I think you are either severely overestimating the capabilities of modern single board computers, or severely underestimating the amount of work a computer has to do to do anything meaningful with a pointcloud.

We all know how that turned out though. XD
