Robot Follower

Hello, I wanted to know if there would be any way for the Robot to follow a person or transmitter. For example, if the gps coordinates of the transmitter are known, programming the robot such that it would go to the location of the signal. Or something like that, just throwing it out there. Let me know if something like that is possible with any of your devices, I would really be interested in buying and implementing it.

Thanking you,
Amish Suchak

Hey Amish,
It is indeed possible. You could use the GPS sensor (http://www.dexterindustries.com/dGPS.html) to track coordinates and the XBee Sensor (http://www.dexterindustries.com/NXTBee1.html) to communicate those coordinates with another robot.

A start?
