PROJECT TOPICHealthcare, Assistive & Bio-Mechatronics
Automated Laboratory Pipette Rig
A laboratory automation concept exploring micron-precision lead screws, anti-backlash nut carriages, and optical liquid level sensing to automate repetitive microplate pipetting protocols.
Micron-Scale Liquid Handling Mechatronics
- ✓Automates tedious microplate dispensing with sub-microliter volumetric precision.
- ✓Incorporates motorized tip pickup and ejection stations to prevent cross-contamination.
- ✓Accepts standard bio-lab assay protocols via programmable script interfaces.
The Engineering Challenge
Problem / Objective
Manual pipetting of hundreds of 96-well microplates leads to repetitive strain injury and pipetting volume variance across assays.
