Abstract
In this talk, Dr. Liu will present his research on robotic micromanipulation of small model organisms including the nematode worm C. elegans and Drosophila larva. These model organisms have been widely used in basic biology research, while their manipulation tasks require delicate skills from operators and could easily cause human fatigue. The low speed, low accuracy and poor consistency of human operations impose technical barriers on large-scale studies involving manipulation of many organisms on a daily basis. They have developed two robotic micromanipulation systems for high-speed injection of C. elegans and mechanical stimulation of Drosophila larvae, respectively. Both organisms are live and freely-moving in nature. Thus, they developed microfluidic devices for automated preparation of individual organism samples, which enhances the manipulation speed, accuracy and consistency. Both systems leverage microscopic vision for real-time position feedback and control multiple micropositioning devices for automated sample manipulation. Micro force sensors and advanced force controllers have also been developed for force-controlled mechanical stimulation of Drosophila larvae. They demonstrate the superior performance of the robotic systems over manual manipulation, and highlight their promise for large-scale basic biological studies on genetics and neuroscience.
