We propose a microrobotic platform that stimulates swimming microorganisms in a microfluidic chip with high speed and accuracy. The developed platform comprises (1) high-speed microrobots that can generate a millinewton-level driving force, micrometer-level positioning accuracy, and a millimeter per second level drive speed through the actuation of motorized stages with permanent magnets and (2) high-speed online vision sensor capable of capturing images on the order of 1000 frames per second. The specific design and architecture of the proposed platform are also presented. The proposed platform stimulates and observes swimming microorganisms in a microfluidic chip through a mechanical approach. This platform provides on-chip investigation with high functionality that has been difficult to achieve with previous approaches and contributes towards the discovery of previously unknown functions of swimming microorganisms in the bioscience fields.

“…The 4 × 4 cell-based labeling circuit module extracted 2048 objects in a 512×512 image and calculated their 0th and 1st moments in real time at 2000 fps. The implementation of the cell-based labeling circuit module was described in detail in [18]. The total execution time of steps (a)-(h) was 0.35 ms, when 15×15 blink dots are used.…”

We propose a novel dot-pattern-projection threedimensional (3-D) shape measurement method that can measure 3-D displacements of blink dots projected onto a measured object accurately even when it moves rapidly or is observed from a camera as moving rapidly. In our method, blinking dot patterns, in which each dot changes its size at different timings corresponding to its identification (ID) number, are projected from a projector at a high frame rate. 3-D shapes can be obtained without any miscorrespondence of the projected dots between frames by simultaneous tracking and identification of multiple dots projected onto a measured 3-D object in a camera view. Our method is implemented on a field-programmable gate array (FPGA)-based high-frame-rate (HFR) vision platform that can track and recognize as much as 15×15 blink-dot pattern in a 512×512 image in real time at 1000 fps, synchronized with an HFR projector. We demonstrate the performance of our system by showing real-time 3-D measurement results when our system is mounted on a parallel link manipulator as a sensing head.
