 | | RC control on Pneumatics, gearboxes and polarity switches
|
|
Hi! [WARNING: Not for the weak hearted LEGO purist ;) ] I'm planning to build a remote controlled LEGO lumber truck. What I'm planning to do is to controll all the functions via a remote controll (eg. Sanwa 5 channel RC equipment). By all the (...) (24 years ago, 7-Aug-00, to lugnet.technic)

(...) Not for the weak-hearted *anything*. You realize, of course, that this could destroy the newsgroup: if you succeed, no one else will be able to brag about anything for months ;-) Suggestion: all the crane trucks I've seen have separate seats (...) (24 years ago, 7-Aug-00, to lugnet.technic)

(...) I'm not entirely sure if Tobbe was referring to the "traditional" type of mobile crane setup here - I rather get the impression, although I may be wrong, that he is intent on making a "logging truck", with a crane similar to that you get for (...) (24 years ago, 7-Aug-00, to lugnet.technic)

(...) Okay! Are you planning on renting a garage for it?:) I can't see a solution to the problem with only 5 controllers (servos or whatever). But how about splitting the functions up, you need a channel to Rise/lower support legs next to the crane (...) (24 years ago, 7-Aug-00, to lugnet.technic)

Hey, you guys are luck My digital Camera messed up and i just got it back and had built a knucle bone (the tern used to call the loader on a logging truck) Well, anyway, I have several pics you can look at. It isn't remote control, but it is modeled (...) (24 years ago, 7-Aug-00, to lugnet.technic)

(...) LOL, that might be a great idea ;) (...) I thought something like this; The RC-controller has two joysticks that combined control four servos. The fifth channel is a switch made for landing gears (it's an model airplane controller). I thought (...) (24 years ago, 8-Aug-00, to lugnet.technic)

There is one very important point that no one has considered. The FCC has set up laws prohibiting use of air frequencies on land vehicles. This is to protect RC pilots from interference from other people on the same frequency. Someone could be (...) (24 years ago, 8-Aug-00, to lugnet.technic)

(...) Not to worry, I've been using that equipment for long and are well in to the laws and such here in Sweden. It's in a legal and open, free band with no restrictions at all. No one uses that frequency for airplanes anymore here in Sweden, and if (...) (24 years ago, 8-Aug-00, to lugnet.technic)

(...) You just build the compressor, and for gods sake - don't use the air tanks! They're great when used with the handpump, but can ruin almost any compressor design. Take a look at the compressor in that awesom "claw truck" (can't remember the set (...) (24 years ago, 8-Aug-00, to lugnet.technic)

(...) Yes you can say that. In fact the old style uses press/suck system and the new style only uses press That means that the suck action uses a sort of vacuum. This is always less powerful then pressure. And you can’t use an airtank. The new style (...) (24 years ago, 9-Aug-00, to lugnet.technic)
