(...) I guess we're talking different things here. You were telling me to use all three motor/sensors. I claim I only need two for my Quad242. I have to see WWW to know what you are talking about I guess, or else you lost me. Static balance requires (...) (22 years ago, 2-Dec-03, to lugnet.robotics)

(...) Well I was restricting the discussion to modifying my Quad242. I think you are talking about something else. I think you were proposing using all three inputs and outputs to run the motors and control switches. I was proposing using less of (...) (22 years ago, 2-Dec-03, to lugnet.robotics)

<SNIP> (...) Look up Tri-Star Wheel. Instead of driving wheels, drive gears that move legs (or pneumatic pumps). Remember that a Tri-Star Wheel uses a differential. When the input shaft is turned, it spins the body of the differential which turns (...) (22 years ago, 2-Dec-03, to lugnet.robotics)

(...) Bad assumption but it would work, the RCX is too limited on I/O to be doing that sort of stuff except in the case of simple rollers/walker. Since legs have symmetry it's silly not to take advantage of it here, you've got to use it to keep the (...) (22 years ago, 2-Dec-03, to lugnet.robotics)

Earlier, Jim Choate said: (...) I think it is important to understand both simplicity and complexity here. For example a fluidic (e.g. pneumatic) cylinders have the potential for redistribution between cylinders of load force. This is equivalent to (...) (22 years ago, 2-Dec-03, to lugnet.robotics)
