Ozobots are small programmable robots that are codable by programming them online on any device or through colour codes that are drawn by you. Intermediate students can use Ozoblockly, an online visual block coding program. Students can create online programs that will transfer to and control their Ozobot. As they become more proficient, they are able to adjust Ozoblockly to learn higher level coding skills.
