我们的研究提出了一个精确的和自动化的控制机制，Janus微电机驱动的催化反应。该系统利用完全可控的电磁线圈将磁场导向参考点，使颗粒响应过氧化氢的催化分解而移动。在没有人为干预的情况下，磁力矩被施加到粒子上，使它们能够精确地对齐和移动。为了确保精确的控制，我们已经实现了将粒子引导到所需位置的算法。此外，由多个这样的点组成的期望轨迹使得活性颗粒能够沿着沿着更一般和复杂的轨迹移动。
Our study presents an accurate and automated control mechanism for Janus micromotors powered by catalytic reactions. This system utilizes fully controllable electromagnetic coils to direct the magnetic field toward a reference point, causing the particles to move in response to the catalytic decomposition of hydrogen peroxide. Magnetic torques without human intervention are applied to the particles, allowing them to align and move precisely. To ensure precise control, we have implemented algorithms that guide the particles to a desired location. In addition, a desired trajectory made up of multiple such points enables the active particles to move along more general and complex trajectories.
