Press the space bar to start the robot and press "r" to reset it. Move the robot by clicking and dragging. You can also move the green dot in the same way. To change the behavior, press 1 for "fear", 2 for "aggression", 3 for "hunger", and 4 for "curiosity".
This is a simulation based on a book called "Vehicles," by Valentino Braitenberg. The green dot is "light" and the green eyes on the vehicle are light intensity sensors. The wheels are driven by motors.
