title: OTTO: The Open-Source and Affordable Liquid Handler for Automated Micropipetting
---OTTO is a liquid handler that can automatically prepare samples for qPCR, flow cytometry, and other biological assays that rely on accurate liquid dispensing. Otto is also:
- a linear motion platform that balances speed and accuracy for timely sample preparation
- capable of lights out sample preparation (set it up and walk away!)
- constructed entirely from open-source parts
- affordable, costing ~$1500

With the help of his advisor and a passionate group of undergraduates (Mateusz Odziomek, Cerie Ock, and Hannah Chen), David brought OTTO to life.
