The only problem with using individual servo control is speed, the time it takes to move 12 servos by individual commands is rather long. This has the effect of slowing the walker down considerably.

I believe the best thing to do is use separte controlers (e.g. PICs) to control the specific motions of the servo's. This will allow you to have more control over the HB.
