Walter Update 2.11.11 Navigation Done
February 11, 2011
Woo Hoo! Navigation, headmoves and audio all about 90% there. There is still a lot of adding-to and cleaning up but it is very nice to be back to a solid base in which to work from. Much more personallity needs to be added, i.e. he should have something to say when getting stuck in a corner etc. The wiimote code I have been working on also needs to be added. The wiimote is being used solely for it's IR camera, using it to find an IR beacon. Basically, the beacon consists of 2 IR leds (constantly on) set 4" apart. Walter can see both leds and with a simple calculation of distance between them, know how far away he is from the beacon. Pretty simple actually with no triangle calculations! I also plan on adding a couple LEDs to Walter himself, allowing me to use the Wiimote as an "invisible leash". I have also had some thoughts of outfitting my smaller robot with the same IR beacon on top. This way, Walter could play follow the leader and hide and seek with him.
Like I said, everything is working great, but still in the KISS format. From here, it is just simple grunt-work to start putting together all of his audio and personallity and adding it to the main code. Nice thing about the Prop, I gotta say, is the fact that all the "personallity" is contained in it's own cog. There is never a fear of screwing up the code you have already written by trying to add to it. Cogs are great!! Woo-Hoo!
I think the video is pretty self-explainatory.
