The document discusses using behavior driven development (BDD) and test driven development (TDD) to develop robot behaviors. BDD is defined as defining desired behaviors as executable examples. Examples are given of BDD scenarios for a follow me robot and comparing BDD to the rigid behavior of a wasp. The use of both BDD and TDD together is discussed where scenarios are used to define behaviors and then tests are written to implement those behaviors.
