 | | MOC - Small Pneumatic Biped Walker
|
|
The other day I was given a challenge to make a small biped using small pneumatic pistons. Normally I don't use small pistons in combinations with switches, because the pressure must be increadibly high for a small piston to flip a pneumatic switch (...)

(...) What can I say? Yet another amazing creation. You have a pneumatic control circuit in there somewhere, I think. I know what you mean about the small pneumatic cylinders needing such high pressure to move a switch. The engine I built following (...) (21 years ago, 16-Jun-03, to lugnet.technic, lugnet.robotics)

(...) Thanks Paul! You are always so kind. The pneumatic control circuit is similar to one found in a two double acting cylinder engine, except slightly different. It makes the walking pace more even from side to side. (...) Kevin (21 years ago, 16-Jun-03, to lugnet.technic, lugnet.robotics)

(...) Hi Paul, I use a electronic schematic style when drawing out my pneumatic circuit designs these days. The combination of a piston that is linke to a pneumatic switch is simply a box, with X and C on the left edge, representing the eXpand and (...)

(...) Thanks Eric. I'm keeping that one for BrickFest. It took me two days to create. It helps to have made a few walkers before... (...) Well, the next step is to try to make it *smaller* :^) (...) Kevin (21 years ago, 16-Jun-03, to lugnet.technic, lugnet.robotics)
