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 functions I mean: Move truck forward/revers Turn truck left/right Rise/lower support legs next to the crane Turn crane left/right Rise/lower crane Bend crane Rotate claw Open/close claw The servos is only allowed to move switches and a steering knob. Just like if some person would be using the truck. Since I plan that much functions I have to make two thingies move with one servo, e.g. Pneumatic switch and gearbox on one servo. Does ay body has any experience with this? Is there any pictures on the net that I might find interesting? Any ideas, pointers and such? I might use an RCX to smooth things up a bit, I'm about to build a test module to see if I can make all these thingies move OK before I start building the truck it self. Thanks! Play well! /Tobbe, Sweden

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)

Ok! The project page is up and running. I'll update it as the work goes on: (URL) if the page is slow, I'll move it to another server when I find the time for it) /Tobbe - (URL) (24 years ago, 16-Aug-00, to lugnet.technic)
