I have several large classes in external .h and .cpp files that are added to my project and compiled into the .lx. I found that when I changed the number of calls to a major procedure from 2 down to 1, the final program size went down 20%. Are these (...) (22 years ago, 13-Nov-03, to lugnet.robotics.rcx.legos)

| | Pneumatic Quadraped 242
|

Hi All, I just snapped some pictures of my latest MOC. It is a pneumatic quadraped that has an advanced walking gait made completely out of lego pneumatics. Instant walking, just add air pressure. Quad242's front left and back right legs are paired (...) (22 years ago, 13-Nov-03, to lugnet.technic, lugnet.announce.moc, lugnet.build, lugnet.robotics)

One of the most import parts of a moco system is how much space the camera needs to cover. They can range from just pan and tilt, commonly called a "hothead" which will either record or playback only rotational data (HPB), all the way up to systems (...)

Hi all, I'm a lurker/newbie. I'm wanting to build a controlled platform that can move and rotate (sort of like a turtle using LOGO). I'd like this platform to carry my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms (...) (22 years ago, 12-Nov-03, to lugnet.robotics)
