ive just done the same kind of leg modification as inspired by hiveminds stock parts approach and so i have to ask where have you put the battery and are you using a stock battery? because after i had attached the legs there was no room inside the guy for the battery, also ive noticed he's become extremely unstable and top heavy making almost all of my previous moves useless.

I use the stock battery, and getting that sucker in is a pain. What you have to do is unscrew the screws on one of the servos that make the legs turn, and then put the battery in. Now here's the hard part; getting the leg back on. I had the help of one other person, and a biiiiggg set of pliers to squeeze the leg in. It's really hard, but afterwards you can give yourself a pat on the back!

Well, I should think that with out a battery or with a battery hanging between his legs he would be unstable...
I once tried to operate my robot without his battery and indeed he was unstable.

I've been trying to make walking and turning cycles with Red Fox Dude, but we still haven't made anything that works. We're also still trying to figure out how to make get-up cycles.

The getup routine from the back isnt too different from what the RN has for default, but the one from the front has to be completely redesigned. Unless... you fix the arms to be the appropriate length. That is, they are far too short for the body now, they need another 40mm or so.

As for the walking sequence, I pm'd you about this a little while ago. But the basic premise is that of short steps. The stock servos and knee joint at 6v dont really allow for a fast gait that is long and stable unlike that of the Manoi or higher end robots, so instead you want to do a sort of jogging loop. I suggest you work on getting your robot to walk in place (check out the robo-one vids: here) and then use a gyro and lean the robot forward to get him going.

I hope that helps a little, goodluck.
