I originally set up this exercise to demonstrate squared vs. linear scaling rules long after my kinematics units were done. I was going to just program a constant velocity and constant acceleration robot, and run them side-by-side for 1 second, 2 seconds, etc. with discussion in between. Then I though it would be easier to program several robots with the set times and just swap out robots. When that was done, I realized i could run them all at the same time, and low and behold they created a living position vs. time graph! This will definitely be my introduction to position vs. time graphs for accelerated motion next year.
