Try running the two-servo code, but unplugging each of the two servos, in
turn. One servo plugged in to the two servo code should narrow down
whether this is a software or power problem. If it only jitters when both
are plugged in, I'd recommend putting a very large electrolytic (1000 uf or
higher) across the 6v close to the servos. Servos draw power in a rather
"spikey" fashion (lots of quick on and off when the motors are stopped,
which means very large current). Two motors on a (rather soft -- low
current and unregulated) wall transformer could be causing you grief. You
can try running the servos off separate power supplies as another test.

| I just read in Nuts & Volts about your triumph!! What an impressive feat! Doesn't it get boring having your robots beat the competition 15 to zip? Just kidding.. I can imagine the excitement you all must have felt to see your creation take off seem (...) (28 years ago, 18-Jan-97, to lugnet.robotics.handyboard)
