MicroTracker.jl is a feature-complete Julia package that tracks and analyzes moving microbots in microscopy video. This package tracks critical microbot metrics including size, velocity, and rotation rate. Combined with easy batch processing of videos, MicroTracker enables high-throughput analysis across multiple global experimental variables. For more information on microbots and this package, please see the short paper.

MicroTracker is built for collaboration and use across the microbot research field. To get started contributing and improving the package, see the setup guide. To report an issue, use the Issues tab 👆. Lastly, to seek support or discuss MicroTracker, please use the Discussions tab.
Various components of MicroTracker have been used in scholarly works1234. This package open sources, combines, and tests the tools written for microbot tracking as part of Coy Zimmermann's PhD thesis work 2018-2023 on magnetically propelled microwheels. This work was performed in the Marr Group at the Colorado School of Mines and with collaboration of the Neeves Lab at the University of Colorado Denver, Anschutz Medical Campus. MicroTracker uses and builds on work from colloidal science researchers56.
