The Lego Mindstorms EV3 kit, coming in September, costs $349 and comes with more than 500 pieces. It has motors, light, color, and touch sensors, and a remote control. It can be programmed via Mac or Windows PC, and has iOS and Android support. Oh, and it's meant for older kids. How easy would it be for me to set up?

I attach motors to the sides of the Brick. The pieces should be familiar to Lego Technic fans, but the style of piece is completely different from standard Lego bricks.

Right now this just spins, but more advanced robots have insectoid legs, joints, and ball-shooting weaponry.
