Let's Make Robots!


Useful robots

Hello :)

I have this question: has any of you ever built a useful robot, that is, a robot with some real task that helps you, instead of just making it for fun ?

The other day a friend of mine was complaining about the time it costs him to cut the grass, and told me jokingly he could use a nice autonomous robotic lawn mower. I thougth that it could be a task within our building abilities.

What other useful robot could be realistically done?
