There is currently a huge barrier to entry into robotics and people who are interested must invest a lot of time and money to pursue advanced degrees in all of the necessary disciplines. As a result, progress is slow and a true consumer robotics industry has yet to materialize.
Rex App consists of a basic and a premium version. The basic version teaches robotics in an interactive and practical way by guiding the user through lessons on how to build a real robotic system. Rex App includes a sandbox feature where the user can test his skills with a simulated robot. This feature will be included in the premium version.
Rex Robot is a complete robot that is a real-world manifestation of the simulation within Rex App. It can carry out physical tasks that are defined and implemented by the user through the app. Rex Robot is modular and can be upgraded to become more robust and useful over time.
