  1. Zero Push Buttons Computer Arduino Manual Volume Selection X,Y,Z position control USB Motor System (5 motors) PipetteMan (Standard model, all sizes are compatible) Fluid extraction/release Tip Release

  2. Electronics • Preserve USB motor system • Arduino (Mini Pro) • More than enough inputs • <$20 • USB/Serial Connection • 2 USB Ports Needed • A usb splitter can be used/included

  3. Zeroing • XYZ Positioning, tip release • Buttons indicate when position is reached • Arduino informs computer • Computer stops motors • Repeat process for precision • Fluid Extraction/Release bottom points • User sets fluid amount on pipeteman • Buttons control exact positioning • User marks bottom, middle, and top points on computer • Should be savable for quick reconfiguration • Possible future option – Force Sensor

  4. Position Control • 3 motors • XYZ Axes • Same system as current printer • Software is largely transferrable • Already tested to required accuracy for liquid transfer • Existing FabInterpreter software

  5. Fluid Extraction/Release • PipeteMan pipette • Actuation: Use motor from 3D printer • 3 reference points • Released • Half-pressed • Fully-pressed • Tip Disposal • Last motor • Electrical contact on button gives position
