breed [cats cat] ; creating the breed of cats
breed [mice mouse] ; creating the breed of mice

The opening statement is to ‘breed.’ ‘Mice’ and ‘mouses’ sets out the program language, of having both a family and an individual. These can be of any names, if the breeds are other than turtles.

Individuals that are close to one another are defined and named as the following. When starting off the agents, the agents will then need to be defined further, by a direction for example.

’nobody’ is a special value used in Netlogo used to indicate the absence of a turtle or patch. The brackets tells the turtle the command to run. ‘set heading towards closest-mouses’ is another command that uses a reporter. There is no space in the words ‘closest-mouses’ as the hyphen combines the two words into a single name.
face danger-cat ; turns the agent to face its danger-cat
bk 0.2 ; asks the agent to move back 0.2 step away from the closest agent

1. Create a number of turtles positioned randomly on the screen
2. State the ’’REPEL FUNCTION’’ for the turtles to form a regular spacing
3. Once the regular spacing between the turtles is formed, the turtles are connected through the additional ’’BRACINGFUNCTION’‘

NetLogo is a multi-agent programmable modeling environment. It is used by tens of thousands of students, teachers and researchers worldwide. It also powers HubNet participatory simulations. It is authored by Uri Wilensky and developed at the CCL. You can download it free of charge.

NetLogo was designed in the spirit of the Logo programming language to be “low threshold and no ceiling,” that is to enable easy entry by novices and yet meet the needs of high powered users. The NetLogo environment enables exploration of emergent phenomena. It comes with an extensive models library including models in a variety of domains such as economics, biology, physics, chemistry, psychology, system dynamics and many other natural and social sciences. Beyond exploration, NetLogo enables the quick and easy authoring of models.
It is particularly well suited for modeling complex systems developing over time. Modelers can give instructions to hundreds or thousands of independent “agents” all operating concurrently. This makes it possible to explore the connection between the micro-level behavior of individuals and the macro-level patterns that emerge from the interaction of many individuals.
NetLogo has many thousands of active users. It is freely available from the NetLogo website. NetLogo is in use in a wide variety of educational contexts from elementary school to graduate school. Many teachers make use of NetLogo in their curricula. NetLogo comes bundled with a large library of sample models covering many domains in natural and social science.
NetLogo was designed and authored by Uri Wilensky, director of Northwestern University’s Center for Connected Learning and Computer-Based Modeling. Development has been funded by the National Science Foundation and other foundations.

The model has 10 shiftbrites connected in an array , and 4 digital micro servos powered with 2 arduino boards.

One arduino board is  for the 4 servos, and the other one for the 10 shiftbrites.

The motion of the servos is controlled with the mouse via processing.

Other Animations tested with Sensor Inputs

INTERACTIVE CHESS BOARD : 2nd Portal to the other scenes of the animation.

The proposal is an interactive chess board. I came across this idea when watching tv..saw these people playng outdoors chess…i found that it exactly represents movement. And the movement is not random. The user(s) moves the objects to a specific position within that boundary of space. The space is a grid by its self. Also the chess board is a link to other scenes of the animation. When the user plays at a position, that position is highlighted and when clicking on it , it will then lead to a scene. There will be  a contact sensor attached bellow chessboard surface which will be activated once the user steps on that area

The user(s) moves on the chessboard,existing are the images of the scenes  projected on the surrounding
campus buildings. when playing on the ‘‘scene portal position’’, the position highlights and a vector appears
indicating where (in which scene of other movement) it will lead. that reacting position is  becoming a sensor. At the same time the chessboard becomes the main portal of movement navigation, and exploration of the local weather understanding and conditions. The higlights oocured due contact sensor attached bellow the chessboard surface which will be activated once the use steps on that boundary.in turn the sensors activate leisers
(indicative vector lines)
