Introduction: DIY Automatic Ball-picking Machine

By

Recently, we made a DIY ball launcher and got a lot of responses.

Then Makeblock share a ball-picking machine to answer our project.

They made it in their Makerathon.And it just cost 48hours.But still

insteresting enough to share with you!

So I share their article here now.(Original)
