As one who made it a self-imposed design condition to exclude active
sensors (and multiple RCX's, and - where possible - anything made
after 1975) I am truely insulted.
Having said that, I too have hit a wall. After almost 8 weeks of
almost flawlessly picking up blocks, my gripper has decided, quite
suddenly I might add, to turn block placing into an Olympic shot-put
event. My design involves having two equally balanced elastics on the
left and right arms to apply equal pressure to the sides of the
block. I think I stretched one of them slightly. I'm having a hell of
a time trying to find a matching pair. A mis-matched pair is o.k. if
you don't mid taking the time to let it find it's center at the bottom
of the stroke (and the added feature that, on the movement up to the
rest position, it nudges the block toward the middle), but if I go too
fast, either the act of lowering the block, or the nudge becomes
enough to land the block on the wall (25% of the time anyway).
Fortunately, I can lift a block high enough to get over this, but it's
still a setback.
Anyway, It's Valentine's Day, so remember:

| So I have revamped Runamok 'Bot with 40 tooth gears for a great speed increase. And the rotation sensors are still accurate at this increased speed. Now, however, the light sensor misses--could be the codeing or the light conditions in my room--so (...) (22 years ago, 13-Feb-02, to lugnet.org.ca.rtltoronto)
