Fishing for a tasty linkage/gearing/robotic building thread...

Hi all,
  I've noticed that it's been awhile since there has been good thread
concerning the building of robotic elements in Lego.  I have nothing against
the really neat conversations concerning the RCX - but- computers are what I
do for a living, so the thing that attracts me to Lego robotics is the
subset of engineering that I know absolutely nothing about - robotic
movement.


I long for the exciting days of Adaptive transmission, syncro drive and
tri-wheelers. Are all the gearheads gone? I wish I could say I had a
tremendous idea to share - but I don't.  Here are some projects that I
_almost_ started:

  An adaptive pressure pump that would have at least two gears.  This would
allow the build up of pressure quickly for the initial strokes, followed by
a gear down for the tougher cycles.  I would like to be able to drive a
couple of the big pneumatic cylinders all at once.

A large and steerable walker (AT-AT?) using pneumatics or gears

incorporating any of the throwbot ball-joint elements in anything.


And finally what I am working on:
A large landing bay for all my star wars rebel ships.  lighted landing
strips, rotating launch pads, minifig lifts - all rcx controlled of course.
Naturally, I will require a robotic arm to lift and rotate ships in need of
repair :)

Anyway - just my attempt to create a robotic-motion thread.  Feel free to
reply with your current project, or just a "me too", and I will send any
interesting bits your way should I find any.

P.S. newbie ideas/questions strongly encouraged!!  Fresh Blood!!

(...) I totally agree about needing a new building thread. It seems like there is a lot of effort for software in a box with only three inputs and three outputs. Whatever turns you on I suppose. We all get enjoyment from this product in different (...) (26 years ago, 12-May-99, to lugnet.robotics)

Michael, If you only need to make right angle changes of direction how about a design where the robot does not turn. You could have one set of axles for forward/backward with 1 motor driving both sides so you go straight. Then to change direction a (...) (26 years ago, 12-May-99, to lugnet.robotics)

All I can say is that I hope Kipling Morris is happy now and thanks for all the help with my vehicle project. (26 years ago, 13-May-99, to lugnet.robotics)
