    Yes and no A bette choice and the one I used is to control the robot out
  of port 1 via joystick, and port two for line to the robot. Its been about
  three years since I worked for Atari, on robots - yes they were planing to 
  release one for 129 +- and it had a remote  control. You could
  pick up a set of atari remote control, throw tinfoil around the case and they
  will work great for interfacing to the robot. With one joystick port you can
  set up the use of 4 motors plus foward and reverse. I used a resistor, then
  a 2n3904 transisor then a 12 volt relay  to control the motor , You could use
   a 555 - 556 timmer instead of the relay. If you ave any other questions just
   reply to me I could dig up a circuit if you really need one. I did work 
   with the person who posted articles in antic a while ago( about 2 years)
   If you are having doubts about what language to use then try to use PNS forth
  it is perfect language for robots.
