Ozobot “Evo” (ozobot.com) is a tiny one-inch diameter robot that can be quickly programmed using a Google Blockly dialect known as OzoBlockly (ozoblockly.com).  Combining the ability to program Ozobot to rotate precisely as desired with Voyager’s ability to sense the resulting motion through its collection of sensors, the possibility of a seemingly endless variety of STEM projects becomes a reality.
