Toy design methods break down the desired behavior of an electro-mechanical toy into unique states represented with electronics and/or mechanical modeling. The toy will exist in such rest state until some external event acts to trigger a state change in one or more of the parts. Any event can be defined at an appropriate user, environmental, or sensory input to can act as a trigger for the toy to react with some predefined behavior. Each of several physical toy states can be uniquely represented with an electronic circuit register. A multi-bit register status at any one particular instant directly represents the entire state the toy is in, and is quick and simple to inspect and act on. State changes triggered by input stimuli cause a change in the register bits reflecting the changing conditions of the toy.
