Few are more excited about Lego\'s new Mindstorms sets rolling out next month than Silicon Valley engineers, AP reported. Many of them were drawn to the tech sector by the flagship kits that came on the market in 1998, introducing computerized movement to the traditional snap-together toy blocks and allowing the young innovators to build their first robots. Now, 15 years later, those robot geeks are entrepreneurs and designers, and the colorful plastic bricks have an outsized influence in their lives. Techies tinker at Lego play stations in workplaces. Engineers mentor competitive Lego League teams. Designers use them to mock up larger projects ideas. And executives stand Lego creations on their desks alongside family photos. The new Mindstorms sets, on sale Sept. 1, are simpler for the younger crowd and more versatile for sophisticated users than two earlier versions. The sets are designed for kids over 10 and make it easy to build basic, remote-controlled robots, including a cobra-like snake that snaps Lego brick fangs. Some shoot balls, others drive along color-coded lines. But for $349, far more expensive than typical building toys, customers get a much more complex and powerful system.
