BioBuddy Autosampler

BioBuddy Autosampler Render

Led a team of 8 engineers to develop the BioBuddy Autosampler, an open-source, compact, and low-cost alternative to commercial laboratory autosamplers, designed for precise, automated handling of small-volume biological samples. The device automates carriage movement, temperature control, calibration, and cleaning, while maintaining modularity for different vial types. The system features a three-axis sampling arm, a contamination-resistant peristaltic pump and valve system, and a piezoelectric Peltier-based cooling loop I designed to regulate sample temperature.

Technologies Used: Autodesk Fusion, Systems Engineering, Peltier Cooling, Peristaltic Pumping, Thermofluid Systems
Key Achievements:
  • Led concept development, subsystem integration, and team coordination as project Team Lead
  • Designed the piezoelectric sample cooling system using a Peltier module, cooling block, radiator, and liquid loop
  • Oversaw integration of modular trays, sample arm motion system, and automated line-cleaning subsystem
  • Reduced estimated unit cost to ~$3,000, over 80% cheaper than existing commercial solutions, without sacrificing precision or reliability
