Development of a Micro-Scale Test Bed for Multi-Agent Control in Bioengineering Applications

This project presents a hardware test bed designed for micro-scale multi-agent control, focusing on bioengineering applications at UIUC, spearheaded by Professor Timothy Bretl. Utilizing visual feedback, the test bed examines various stimuli such as galvanotaxis (electric field), phototaxis (light), magnetotaxis (magnetic field), and chemotaxis (chemical gradients) through different microorganisms. The study emphasizes the fabrication of test samples, optical setups, and results in motion control. Future work aims at enhancing repeatability, micro-manipulation, and actuation systems.
