Since the programming is preinstalled, you can build the TRACK3R out of the box without connecting the Intelligent Brick EV3 to a computer (which is necessary to program any other robot).

We try building our first Lego Mindstorms EV3 robot, and make some decent headway.

Aimed at older children and adults as well, the robots use the same fundamental pieces as regular Lego toys, but they also add motors, sensors and a form of computer programming to the equation.
