could you elaborate on how we could use kinematics because so far we have been testing extensively however it seems impractical to calibrate for all the points that are possible.
I had graphed 90 or so graphs using the averaged data for each peg and angle (Some were estimated by using kinematics because we had all of the variables needed that we chose. I also payed attention to the small stuff). We printed copies, and used that in our testing and competing.
My machine is built where most of the human factors have been removed or greatly minimized. In other words it is really consistent and predictable, all except for the bungees and their mounts.
There is a slight difference in force and speed when shooting a steeper shot than when shooting a shallower shot. This is because of gravity. However it didn't make much of a difference at State Competition
Also I have found that there is no reason not to use an electromagnet for the trigger device. It is the best idea ever. I also made a change to my last design before state, but forgot to post pictures, they should be up soon.
