Hi all, I am looking at buying the book - Extreme Mindstorms. Any comments welcome. I am an advanced user, and am looking for some ideas. For those who have it, what customized sensors do they provide instructions to build? Dave (24 years ago, 25-Mar-01, to lugnet.robotics)

(...) I'd suggest that you try this again mid-summer. The solar radiation angle is still fairly low at this time of year with much of the energy being scattered by the atmosphere as well as being spread over a larger surface area of the earth. I (...)

What kind of ankle joint? A motorized one, or passive one? If it is the first type I think the leg will be too heavy to be moved quickly. That is critical since the robot falls onto itself. Looking closer at the design, I think that you only need to (...) (24 years ago, 25-Mar-01, to lugnet.robotics)

After viewing the walder movie, I wonder if it would work with flat feet, and an ankle joint? Gravity would keep the flat foot pointed down when the leg was lifted. - pete. (...) -- Pete Sevcik sevcik@flash.net Techno-stuff Robotics (URL) for FUN ! (24 years ago, 24-Mar-01, to lugnet.robotics)
