(...) These days I buy my small pistons from Dacta. Last time I checked, they had a combo pack of small pump, small piston and three short hoses (black, grey and blue) for $10. I bought most of my small pistons that way (30). (...) Yes, the 31 (...) (19 years ago, 4-Oct-05, to lugnet.technic, lugnet.robotics)

(...) That's good - not many of us have that many small pistons! I wish TLG would bring them out in a set again. I remember when they used to be available as spare parts they cost as much as a large piston. 31 pistons and 32 switches is a similar (...)

(...) Ah - now you have pointed it out I see it. I am not a Lego only evangelist, but there is scope for it to be replaced with some Pole Reverser switches and a Lego frame. I am wandering if an RCX could be used with it, to automate it for fun. I (...) (19 years ago, 4-Oct-05, to lugnet.technic)

| | Hex565 - one leg at at time pneumatic hexapod
|
|
Over the last few weeks, I've been working on a pneumatic hexapod that moves one leg at a time. I got it working this morning. It is pretty cool. It uses 7 large pistons (six for making the legs move forward/backward) and one for controling the (...) (19 years ago, 4-Oct-05, to lugnet.technic, lugnet.announce.moc, lugnet.robotics) !

(...) Yes. I've used it in walkers to switch from forward walking to reverse walking, and to switch from walking to turning and back. I move them by hand, rather than with pistons. With pistons, I consider them XOR gates. They work very well. Thanks (...) (19 years ago, 3-Oct-05, to lugnet.technic)
