We have an axis camera, kinect, rasbery pi(were not entirely sure how to legally use it so instructions for that would be helpful as well) and an encoder on the gearbox running the thrower

My understanding of how a camera distance sensing works:
1. Use a light to light up the retro reflective material.
2. Use camera and software to detect and measure the size of the retro reflective material
3. use this data to triangulate your distance
OR I suggest you use an ultrasonic
sensor
The process
1. mount sensor high
2. read voltage from signal
3. use calibration factor to know how far you are.
These sensors are pretty darn accurate.
I would find another supplier than robotmarketplace because of ship time, but other than that, this is a great sensor.

Create a mechanism with the so called "sweet-spot" so that you can use the same power, but score from many locations with the same exact shot pattern.
