Edit: I don't expect many of you to read though this blog. This ended up being a way to "think out loud". It helped to write these ideas down.
It's probably not a great idea, but I'm using a wireless Wii Nunchuck as the remote on my hexapod.
On start up the hexapod uses the joystick as direction control with rotation control performed by pressing the "Z" button and rotating the Nunchuck to one side or the other.
I'm trying to come up with a way of having the input from the Nunchuck able to control different aspects of the robot.
