A Killough platform is a triangular vehicle with three "omni-directional" wheels that can move or rotate in any direction. Here is my version using Power Functions motors. The obvious arrangement is to have one motor for each wheel. Instead, for an (...) (17 years ago, 13-Nov-07, to lugnet.technic, lugnet.announce.moc, FTX) !

Very, very impressive! Am I the only one who always feels like a simpleton when some of the technique/motor lads post? 'Just for the challenge...' ; ) Oh well, we can't all build castle : ) Great work and I love the rotating of three sets of wheels (...) (17 years ago, 14-Nov-07, to lugnet.technic, FTX)

Thank you very much for the nice comments! Here at last are some videos of the Killough platform in action (sorry for poor quality).

(...) I'm enjoying it- I'd enjoy instructions even more! How are your controls working? You control each motor with one IR channel, right? So you have to convert linear-to-holonomic in your head? In real time? (17 years ago, 24-Nov-07, to lugnet.technic, FTX)

(...) No - the mechanism with the differentials does precisely this conversion for you! As you say, there is one IR channel for each motor. I am controlling it using this: (URL) The joystick on the left (inspired by this one (URL) from Mark Bellis) (...) (17 years ago, 24-Nov-07, to lugnet.technic, FTX)

The PF parts are not shown, but it should be clear where they go: (URL) For anyone planning to build one, there is a warning: the way the wheels are put together may cause some (...)

(...) Thanks a lot, Alexander! Now I have to find enough ballon wheels... or substitute Rama wheels ;o) Two little remarks about the mpd: The "whole" model should be the first in the MPD (Multipart > Model Sequence) You can add all PF parts that I (...)
