| | Is an RCX Output Amplfier, possible ?
|

I'm a not an electrical engineer and I couldn't even play one on TV : Ok. That being said, would it be possible to amplify the PWM output from the RCX to run multiple (2-4) motors off a single output connector using an external nicad battery ? Can (...)

Just a thought: Couldn't one make a "rosetta stone" wheel of the various LEGO(R) colors that uses an angle sensor for indexing them and then just compare the brick being "measured" to the known bricks on the wheel ? It'd be cumbersome, but not very (...) (25 years ago, 7-Feb-01, to lugnet.robotics.rcx)

I'm pretty sure there were no filters involved. This was the basic robot arm that can be built from the 9740(?) Control Lab Starter Set for the Serial Interface Box.

I think a worm gear and a 40-tooth gear worked for me. A string was fixed above, and wound around the axle connected to the 40-tooth gear. This wasn't fast though, more like a slow climb.
