Abstract: A method and system for capturing a Finite State Machine (FSM) description of the desired behavior of a device, and converting that description into a program that is executable by the device. In the preferred embodiment, the device is a programmable robot toy. The user enters an FSM description of the desired behavior of the robot toy using a graphical user interface running on a personal computer. When requested, the preferred embodiment compiles the FSM description into a program executable by a virtual machine running on a micro-controller inside the robot toy. This program is sent to the toy via an infrared transmitter and infrared receiver, and stored in the toy's memory. Then, when the robot toy is used, the virtual machine executes the stored program so that the toy behaves as specified by the FSM description.
