Mechanical overview

Generally, LabAutoBox consists:

  1. Raspberry Pi computer
  2. Microfluidics components for liquid handling (multichannel syringe pump, 3 peristaltic pumps, pressure compensation vessel (PCV), 8 4-way servo driven stop-cock valves)
  3. Electronic box that contains the boards for controlling these microfluidic devices and the XYZ motion robot that works with them
  4. Aluminum extrusion frame for supporting the microfluidics devices
  5. ATX power supply unit (PSU) normally used with desktop computers
  6. Tubing 1/8 inch and 1/16 inch diameters for connecting the LabAutoBox to robotics for doing 8 channel pipette liquid handling

The electronic box is used for controlling XYZ gantrys (like 3D printers, old laboratory automation systems, labbots). The attached Raspberry Pi runs the LabAutoBox browser based software and on the front of this electronic box are connections for hooking the different devices for doing liquid handling based laboratory automation.
