Subject: [alt-beam] Re: Turning a walker


Hey Stiquito is a similar design. 6 legs, but only 2
inputs to control. It turns easily too, if you set it
up for the proper gait. I have been trying to get one
to work with a Bicore, but haven't had much sucsess.
Anyone suggest a Nitinol motor driver?

Everything I say can mean one of two things...If something I say makes you mad....I meant it the other way.
