Here ( http://letsmakerobots.com/node/80 ) Frits had mentioned that either Arduino or PICAXE can control such and such number of servos. I'm pretty new to microcontroller world, so maybe my question will sounds a bit stupid... but I don't really get what we mean by saying "can only control X servos"? Does it actually mean, "platform X can have up to N serial outputs"? Because, AFAIK that's what servos are, aren't they?
Now, I can understand that PICAXE has also limitations due to the built-in Basic interpreter; but why Arduino?
Lots of Hitec and Futaba servos, with good prices, but wait, there's more!
Many mechanical linkages for using continuous rotation servos as gear motors, torque amplification gearboxes for servos, pan-tilt heads, and even a robot section.
