Title: servos and motors
Post by: gshoger on May 26, 2007, 06:42:05 PM

hello, just starting to get into robotics.  i want to build my first one, but i have some questions.  i am fallowing the $50 robot tutorial, and one step has you connecting the two servos to the two wheels.  i thought servos only rotated 180 degrees, so how is this supposed to act like a wheel?

also, if im using a transmitter and a receiver for my robot, do i connect a motor directly to the receiver somehow?

you mod the servo for continuoues rotation

the servo should plug right into the receiver

I found an instructable for a 325 servo. do as he says and solder teh resistors to the wires not to the pcb. I kinda messed up one servo doing that

ehhhh I think adding the resistor method is entirely unneccessary . . . and its harder, too ;D
