ãPresentation

Robbie is very simple robot that walks in a 3x3 cell room and can go outside (through a door) in order to eat a piece of cake. In the room, there are some physical objects: 2 keys (one opens the door) and a cup of coffee. The basic situation at T0 is like illustrated in the following figure:

ãModel structure : MODELROBBIE

The model of Robbie is defined by the following code, stored in the variable MODELROBBIE. Then, it can be compiled into the BASE by the function: MAKEMODEL[MODELROBBIE] After that, a simulation can be launched by the function: DISPLAYSIMULATIONPANEL[MODELROBBIE, 10, 0.1] (see below for arguments 10 and 0.1)

In order to see the simualtion prperly you have to open a large window with at least 1200 pixels width, otherwise the simaula tion panel will be jaggered

ãSimulation panel

The simulation panel is displayed at T0 by DISPLAYSIMULATIONPANEL:  argument 1: a model variable  argument 2: initial value of STEP MAX  argument 3: initial value of SPEED
