Creating a Robot to Guard Property with Lego Mindstorm :: Robotics

The ProtectobotAbstractMy final examination project is to build a zombi that result use non-violent techniques tokeep brutes out of yards. Using the Lego Mindstorm Kit I was able to completethis project. When certain savages walk by my robot, it throws gears towards the fleshly to dart it away. It disregard tell the difference between good animals and bad,and does not stultification them in any way.BackgroundFor many years people train been trying to find non-violent ways to keepanimals out of their yards and away from family pets. mixed attempts haveincluded motion chanceing sprinklers, electric fences, fake smells, and ultrasonic sizable bursts. These devices work in some cases but not in all.Motion sprinklers spray short bursts of water when they detect animals.Some animals however, alike to get wet so the motion sprinklers give not necessarily work on all. Ultrasonic sound burst devices detect when an animal isnear and sends out a deuce second ultrasonic sound burst. These bursts can beheard by animals but not by humans so they may have a hard prison term figuring outwhen the batteries run out or when it is broken. Electric fences can sometimeshurt animals, including pets that argon allowed to be in our backyards. Fake smellsof the animals enemy can also help scare the animal away.There are often unwanted animals in my familys backyard. They occupy ourfruit from our trees, and tear up our grass. We have been trying to find more(prenominal)effective ways to keep them out for a long time.For my final project, I decided to make a robot that will detect when ananimal walks by it. When it detects an animal, it will throw teeny objects at some(prenominal) it is that moved. I have not yet decided what it is that my robot willthrow. It has to be harder than a sponge, but cannot be so hard that it will hurtsomething. As a warning to humans, it will make a beep noise before it throwsthe object.ProceduresI built many small parts to put together to mak e my functioning robot. It ismade up of the insertion pad, gear/motor station, the RCX curriculum, and thehead. I first built the launching platform. It is made up of black beams ranging insize from one to sixteen. They are put together in rows with reinforcements onthe opposite sides running in the other direction. They came together to form atriangular shape with two gears at the end.I then attached gears and a motor to the platform so that the motor is able
