Here's a video of the range sensor scanning back and forth. I finished the code to do a twenty-one point scan across approximately 160 degrees or so in front of the robot and return a Python display of range points. The display doesn't look all that great, in my opinion, but at least it shows if there's something pretty close to the robot. I'll do a bit more tweaking, I guess.
Soon, I think, I'll put up more video.
