Mission

Reduce repetitive manual hydrogel dispensing and aspiration tasks while improving consistency and throughput.

Problem

Researchers were performing repetitive fluid handling operations manually, resulting in time-intensive workflows and variability between runs.

Approach

Developed an automated XYZ gantry platform capable of dispensing and aspirating fluids across standard well-plate formats using interchangeable reservoirs and custom nozzle heads.

Key Innovations

The system combined XYZ gantry automation, a modular reservoir architecture, high-volume and low-volume dispensing modes, and a custom FluidCAM GUI that eliminated the need for G-code programming.

Outcome

Delivered a fully functional prototype capable of automated fluid handling with approximately +/-5 uL precision and earned First Place at UBC Design & Innovation Day.
