Tech Files First Look: Building a 'bot with Lego's new Mindstorms EV3

What’s better than unboxing a new tech toy? Playing with it for the first time.

That’s what I’ve been doing recently with Lego’s new Mindstorms EV3 robot kit. Over the course of several days, my assistants — my son and daughter — helped me build and test our first EV3 robot.

The EV3 kit comes with instructions to build only one robot, a tread-based one called the Track3r. We followed the instructions, built the robot, then started programming it, first using directions provided by Lego and later by creating our own routines.

You can see some of the steps we went through and the finished result below. My review of the EV3 will be available later this week.
