transmitter/receiver
« on: May 27, 2007, 11:41:23 AM »
i am going to buy a transmitter and a receiver because i want to build a remote controlled robot.  i have one question about the number of channels.  if i want to be able to control three servos/motors, do i need a transmitter with three channels and a receiver with three channels?  does each channel control a different part of the robot?

thanks

You can get by with just one transmitter and one receiver.  if you are using somethng like this (http://www.sparkfun.com/commerce/product_info.php?products_id=872, it is a simple matter of transmitting a serial command that would be received and processed on the robot.  One command would be to turn the robot left, another command to drive forward, another to turn right, etc.
