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

The ProtectobotAbstractMy final project is to build a zombi that pass on use non-violent techniques tokeep physical(prenominal)s out of yards. Using the Lego Mindstorm Kit I was able to completethis project. When certain brutes walk by my robot, it throws gears towards theanimal to flash it away. It give notice tell the difference between good animals and bad,and does not injury them in any way.BackgroundFor many years people arrest been trying to find non-violent ways to keepanimals out of their yards and away from family pets. assorted attempts haveincluded motion happen uponing sprinklers, electric fences, fake smells, and supersonic telephone 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, manage to get wet so the motion sprinklers go away not inevitably work on all. Ultrasonic sound burst devices detect when an animal isnear and sends out a 2 second ultrasonic soun d burst. These bursts can beheard by animals but not by humans so they may have a hard condemnation 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 run down 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 pocket-sized 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 p ut together to make my functioning robot. It ismade up of the origination pad, gear/motor station, the RCX weapons platform, 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
