1. Manual Volume Selection
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 Same system as current printer
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
