Here are a few simple applications of various ideas, mainly things such as genetic algorithms, physics and general ALife topics.

Cart and Pole

The cart and pole is a classic control problem, used by some as a benchmark for a controller. The simple version is trivial to control, which is why it is a good way to check your controller is working.

Ants are often studied by Artificial researchers. This is probably because each individual ant is quite simple, but the ant colony as a whole can be quite sophisticated. Ants show classic emergent behaviour.
