Here is a great weekend robotics project to undertake with friends or folks at your local maker space. You will need a 3D printer handy to 3D print the STL files attached as part of the steps below and a Cup, in my case, I am using a Venti Cup from Starbucks which i saved after enjoying my ice coffee.

Here is a video demo of the CupRobot in action
