Iris Navigation Videos

I’ll have to write several posts to fill in the details about how Iris went from being a bundle of wires on my desk to an actual moving robot, and then various wirelessly programmable evolutions of that moving robot; but, in the meanwhile, here are some videos of the progression:

Install the Wolfram Language on Raspberry Pi

Working with the Raspberry Pi Foundation, effective immediately there’s a pilot release of the Wolfram Language—as well as Mathematica—that will soon be bundled as part of the standard system software for every Raspberry Pi computer.

Here’s how one would take this whole technology stack and use it to switch on LEDs by setting voltages on GPIO pins:

And here’s some image analysis on a selfie taken by a RaspiCam:

Future Raspbian images will ship with the Wolfram Language and Mathematica by default; existing users with at least 600MB of free space on their SD card can install them today by typing:

             sudo apt-get update && sudo apt-get install wolfram-engine


Hello world!

Welcome, anonymous internet reader, to my latest blog creation! ^__^

My blog about dance is at, and I really should start updating that one again, too.

Anyway, I decided to create this blog because I’ve recently gotten back into doing some robotics hacking in my spare time, and I’ve decided to chronicle some of my endeavors here (particularly ones that may help others avoid pitfalls I encounter along the way).

I hope that some of the content I post does have a positive impact. Comments welcome!
