Hello fine people of robotics connection,
This is my first time posting on this forum so bear with my newness.
I am in the course of attempting to build a robot capable of tracking and then following a slow moving object (ie slow human walking speed), I do not have to worry about any object avoidance aside from not running into the target and only have to deal with slight bends in the 'road' while following the target.
After much research have decided that the simplest way to accomplish my goal was with IR tracking. The plan is to have the target emit IR and then have the robot triangulate the position with 2 IR sensors and then using the seralizer communicate back to a host PC using the Xbee module and board which I already have (but have not used) from a previous group project.
What I really need your guys/gals help with is that since I have no past experience with robotics (but willing to learn!) I have the following questions:
1. How do you build a simple circuit capable of emitting IR to be attached to my target. I imagine that it would have to be at a certain frequency based on the sensors that we are using. that leads me to point 2.
2. What IR sensors/lights should I consider? and where can I find the data on them?
3. Is it possible to use the sharp IR rangefinders for my purpose (since I have access to 4 of them) by only using the transmitting side on the target and the receiving side on the robot (ie removing or blocking the receiving side on the rangefinder)?
Here is preliminary overview of the project:
Thank you for taking the time to read this and any and all help is much appreciated!
