There are three different ways to code a Sphero. The three different ways to drive them or code them are by java script, blocks, and driving. The different ways to code an Ozobot are by using an app and drawing out a shape with coded blocks, or by drawing in real life on a piece of paper and putting it over the line you colored. Sphero is better for school subjects because you can do way more things with them.I like Ozobot better because you can draw lines in real life then it follows the line with censors.
