First time posting here, just wanted to say hi, and maybe get a little help with a project.
ok i've been thinking about doing a project with some type of laser detection. The basic idea is to have a laser, and have a robot go to the laser. kind of like the light following robot, but more the light is going to be more specifically a laser.
Now i've been searching online but i'm having some trouble here, with detecting the laser.
Ok first off i need some way of detecting the light. I plan on using a visble laser, like a laser pointer, i think the frequency is something like 650nm.
So can i use a phototransistor and a filter?, to get just the frequency of light from the laser. Then set up like a 2 on my robot and use them as "eyes". I planned on running the output of the filter into an Analog to Digital input on my microcontroller. From there i can write the code to control everything else i need.
Also this is something i've been thinking about, now with the above mentioned plan, i was planning on haveing the robot go to the specific spot that the laser is originating from, specificly have the robot come right to the laser pen. But would it also be possible to say point the laser at the wall and have the robot see this as the target it needs to go to. So could the Phototransistors pic up on the reflection of the laser as if it where the laser starting point itself?
I'm a computer enginneering, but i'm still working on my EE skills, so any help would be great. Setting up the filter might cause me a bit of trouble too.
thanks for you time
