Just be careful with the Wii-mote, because it can’t EMIT IR, only receive it. As for the Bluetooth, hey if you can do it, do it.
After a bit more work, we wired up the Whammy bar to control speed, and the green and red buttons as forward and reverse respectively for one motor, and blue and orange for forward and reverse on the other. Yellow is ignored.
So this chord drives it forward:
10010
Reverse:
01001
Clockwise rotation is:
01010
Counter-Clockwise:
10001
The whammy bar returns an analog input between about 100 and 220, and we first divide it by ten, then multiply it by ten to remove the jitters. After that, we use some math functions to assign the Victors the speed based on the input from the whammy bar.
Honestly, I love it. In all honesty, if I end up driving the robot, I’m using this control system. The Whammy bar is in such a great spot, and all you have to do is push on it to ramp up the speed. The direction is so simple, and easy to switch from one direction to another. It’s less motion than the regular joysticks, and you can easily drive it around for ages without tire. As long as you’re GOOD at Guitar Hero, you should be fine.
Three pics are of the box we use as a hub for the port 3 devices we have, the HUD and the guitar, as well as the kill switch and the hybrid/user switch.
If anybody can recommend a good place to upload video, I’ve got some of out proto-bot in action. nothing but a drive train, so no big secrets getting leaked (Like our Fuel Cell…).
