Ultra-high-speed Robot Hand and Eye for Investigation of Microorganisms in a Chip

In this paper, we propose a novel high-speed microrobotic system toward swimming-microorganism capturing and sensing in a microfluidic chip. This system consists of high-speed on-chip microrobots as robotic hands with a maximum speed of 10 Hz to handle a microorganism and a high-speed on-line vision sensor as a robotic eye with maximum speed of 2000 frames/s to track the trajectory of microorganisms/microrobots. The performance of microrobot a and vision sensor is confirmed through basic experiments. Finally, we succeeded in on-chip separating, capturing, stimulation and evaluation of microorganisms by using the developed high-speed robotic system.
