The Protectobot


My own final task is to create a robot which will use non-violent techniques to

retain animals out of yards. Using the Lego Mindstorm Kit I was in a position to complete

this kind of project. The moment certain pets walk by simply my robot, it throws gears on the

animal to scare this away. It might tell the difference between good family pets and awful

and does not injury them at all.


For several years people have recently been trying to find non-violent ways to retain

animals out of their back yards and away from family household pets. Various attempts have

included motion uncovering sprinklers, electric fences, false smells, and ultrasonic

appear bursts. These devices work in many cases but not in all.

Motion sprinklers spray brief bursts of water after they detect pets or animals.

Some family pets however , love to get wet so the motion sprinklers will never

necessarily focus on all. Ultrasonic sound burst open devices detect when an creature is

near and sends out a two second ultrasonic sound broken. These bursts can be

heard by family pets but not by humans thus they may have trouble figuring out

if the batteries run out or in the next broken. Electric fences can sometimes

hurt animals, including house animals that are in order to be in the backyards. Fake smells

with the animal's foe can also help scare the animal away.

You will discover often undesired animals in my family's back garden. They eat our

fruits from our trees and shrubs, and split up the grass. We have been trying to find even more

effective ways to hold them to a long time.

To get my last project, I decided to make a automatic robot that will identify when an

dog walks because of it. When it picks up an animal, it will eventually throw little objects for

whatever it truly is that transferred. I have not decided what that my own robot will

throw. It really must be harder compared to a sponge, nevertheless cannot be so difficult that it will damage

something. As being a warning to humans, it can make a beep sound before that throws

the thing.


I built various small parts to set up to make my functioning robot. It is

composed of the launching pad, gear/motor station, the RCX platform, and the

brain. I 1st built the launching system. It is made up of black beams ranging in

size from a single to sixteen. They are put together in series with rearrangements on

the alternative sides using the other direction. They came together to form a

triangular shape with two gears towards the end.

I then attached gears and a motor to the system so that the engine is able
