Omni wheel robot

Abstract: This project is about building a three wheeled robot car with Omni wheels. Omni wheels can make a robot drive sideways without rotating first. They can make a robot rotate at the same time as it goes straight ahead. An Omni wheel robot can for example be good choice for a tracking robot, though it can drive more effective than a robot car with regular wheels. The thing that speaks against Omni wheels is that it has more friction and it takes more power to rotate the wheels. This robot car is an obstacles avoiding robot that should with help of Ultrasonic sensors and IR-sensors be able to drive around in a room without crashing in to objects or walls. With the help of Omni wheels the robot should drive without rotating much which makes it more effective than a robot car with regular wheels.
