Ozobot “Evo” ( is a tiny one-inch diameter robot that can be quickly programmed to follow lines using a Google Blockly dialect known as OzoBlockly (  This lesson combines the ability to program Ozobot to follow a circle at constant speed with Voyager’s ability to sense the resulting motion through its angular velocity sensor.  The purpose of this project is to show that if speed is kept constant and the same for all objects moving in circles of different sizes, then the magnitude of the angular velocity is inversely proportional to the radius of the circle.
