Hi All, I just snapped some pictures of my latest MOC. It is a pneumatic quadraped that has an advanced walking gait made completely out of lego pneumatics. Instant walking, just add air pressure. Quad242's front left and back right legs are paired (...) (21 years ago, 13-Nov-03, to lugnet.technic, lugnet.announce.moc, lugnet.build, lugnet.robotics)

(...) The key to making this work is to ensure that there is tension at either end of the run that keeps the worm gear at one end of the axle or the other until it hits a hard stop. For example, my robot arm uses rubber bands to hold the gripper (...) (21 years ago, 13-Nov-03, to lugnet.technic, lugnet.robotics)

(...) One way to do that is to have a rubber-band/spring/shock holding "Output B" in it's starting position. Then, you can use a differential to move both A and B. Going forward, A will be easier to drive, so it will push A to it's limit, then B (...) (21 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)
