(...) I totally agree. I think their is one simple metal part inside a pneumatic ram, and that's mostly cylindrical. An LA must have it's ram,worm gear,worm gear rack, and maybe(hopefully) a bearing all made of metal. Seems like the usual Lego (...) (17 years ago, 23-Feb-08, to lugnet.technic)

The only way I can see these being cheaper to produce is if they have no matel parts at all which would make them even worse. And yes you would need a means to power them throuh a series of gears and universal joints which I think could be more (...) (17 years ago, 23-Feb-08, to lugnet.technic)

Hello, LUGNET readers. In case you don't know, I'm the lugnet.robotics.nxt curator. I used to update the NXT section sidebar with [in]frequent regularity, but during the last couple months I've not done anything to it. I get busy and/or don't take (...)

(...) Obviously with *my* interests, I hope that the linear actuator is not the end of pneumatics. There are still a lot of ideas I've not had a chance to try, but more part type options are great! Kevin (www.kclague.net) (17 years ago, 21-Feb-08, to lugnet.technic)

I can't see from your photos how you're stopping the main structure lifting off the base. Correct me if I'm wrong, but crane turntables hold the superstructure down so the load moment is transferred to the crawler base. I've seen photos of cranes (...) (17 years ago, 21-Feb-08, to lugnet.technic)
