I'm working with a double pendulum which I have modeled using Lagrangian mechanics. The physics isn't necessary to understand the problem I'm having.

A professor at my university helped me use mathematica's NDSolve[] method to obtain a graph. I would like to get a list of data points from this graph for every 0.5 seconds (running from 0 to 5 seconds). I've tried using the Reap[] method, following the documentation, but haven't had good results. I've also tried simply entering the graphs function evaluated at 0.5, 1, etc. to no avail.

I have attached the notebook; any help is GREATLY appreciated.
