Internet Controlled Satellite Transponder (Using
A Remotely Controlled Robotic Manipulator)

• remote control of a satellite transponder through
  a robotic manipulator mechanically changing
  controls on the receiver
• interfacing between robot and server (RS-232)
• interfacing between receiver and server
• interfacing between server and internet
• teaching the robot (trajectory planning and
  generation)
