#### Video: Zig Challenge – Part A

This video (22:22 min) provides an introduction to the Zig Challenge. In it, we propose a control algorithm to solve the problem. However, we find that it does not work as well as we hoped. It sets the stage for our exploration in Part B.

#### Video: Zig Challenge – Part B

Our proposed control algorithm in Part A didn’t work so well. It produced oscillations that refused to die out. In this video we’ll take a break from the mathematics and collect data on what the human brain does, subconsciously, when it tries to damp out oscillations. Later, we will learn from this to design elegant control algorithms that kill the oscillations.
