I am currently building a self balancing robot, it can be found in the NXJ projects section. I have just built my second robot, and was wondering if anyone had any suggestions for a sensor which I could use for a follow the leader type formation.
My current idea's are,
- Put an IR source on the back of the leader, and use the IRSeeker to follow, using the signal strength to guage the distance (not sure how accurate this is)
- Put a mirror on the back of the leader and use an EOPD sensor, this seems the be the best option right now.
- I have ruled out an UltraSonic sensor, as when I operate two the tend to intefere with each other.
Any thoughts and ideas would be greatly appreciated,
