(...) But weight is not the only force happening - something has to move it laterally. When the leg is pulled sideways the link doing the pulling is in tension, the heavier the bot is, the more tension there will be. ROSCO (17 years ago, 24-Oct-07, to lugnet.org.ca.rtltoronto)

(...) hummmmm, maybe Im not understanding. as I see it, all the "weight" is at the one pivot point in the leg that attaches to the "frame." (the thick black line in Philo's Gif.) Chris (17 years ago, 23-Oct-07, to lugnet.org.ca.rtltoronto)

(...) You might find that the beams that pull the leg sideways are under enough tension with a large version to cause problems though, especially if moving over difficult terrain. ROSCO (17 years ago, 22-Oct-07, to lugnet.org.ca.rtltoronto)
