Re: What sensors are used to detect the hot LED lights on the FRC field?

Thanks Alan,

I guess I can buy that would work in Theory... but my question is more along the lines of how do you know you are pointing ONLY at the horizontal target when placing on the field?

What does the person placing the robot on the field see/use to confirm the light is on the horizontal target, if the light is reflected back is to the sensor.

In the case of Laser, maybe the person can try and place their eye near the sensor everytime to confirm location, but how do you do this with an IR which is not in the visible spectrum?

It seems like this is a cumbersum way to position the robot, especially if you have to position the bot and continuously place your eye near the sensor for confirmation. Am I overlooking something? Somehow you need to guarantee you are not looking at the vertical target so you don't get false responses.

Does this system require, another method for position the robot to increase likelyhood that you are looking at the right point?

Regards,
Kevin
