The newest contest from the X-Prize foundation is for teams of parents and children working together, and using LEGOS!
The article, "“MOONBOTS” Challenges Parent-Child Teams To Conduct GLXP Missions With Lego" can be found at:
This sounds like a lot of fun. I wish I had an elementary-school-aged child so we could participate in this. It's basically design, build, and program a robot using the LEGO Mindstorm kits to be able to do some of the same tasks required of the Google Lunar X-Prize.
Have fun, learn something, & play with LEGOs! What more could you want?
More information will be posted once the Moonbots website is up. Appearently, there's an hour to go, but you can also follow the Moonbots on Twitter: http://twitter.com/moonbots
