I'm attempting to build a tracking system that will consist of a robot containing a receiver that will follow and track a transmitter that will be attached to a mobile user. I want the robot to maintain a 2 meter distance from the user so if the user accelerates, the robot accelerates, or if the user decelerates, the robot decelerates. I'm wondering which type of sensor I should use to measure the distance between receiver and the transmitter. I've done some research on rf, infrared, and sonar sensors, however, I'm not exactly sure which would be best for this application. Would it be possible to measure the distance with just a transmitter and receiver or would I need transceivers?
