Yesterday I unboxed the new Lego Mindstorms EV3 set, and even before powering on the microcontroller brick, I’d noticed a number of interesting changes, both great and unfortunate, as compared with the previous set, called Lego Mindstorms NXT 2.0. Up to that point, I’d assumed the mix of Technic beams and pegs were more or less the same, and that it was the microcontroller brick and programming environment had been upgraded.

In the next week or so I’ll check out other aspects of the new set like programming theLego Mindstorms EV3 brick and details of the models you can design with the set. In the meantime, let’s check out what has changed.
