Fire-Fighting Robot Contest
One of the activities I ran at the Science Museum of Connecticut in the early '90's was an after-school & Saturday program involving high school students building Robot. I came up with the practical, realistic and yet fun idea of having the Robots find and then extinguish a fire in a house. After running at the museum for one year, the contest moved to Trinity College where it became a huge international success.
I am no longer organizing the Trinity Contest, but it is still running and here is the link.
