大多数自主移动的机器人都配备了电池作为能源。由于储存在电池中的能量与它们的体积成正比，因此随着机器人的小型化，操作时间大大缩短。要解决这个问题，必须从外部供给能源。以检查电站管道为目标，研制了一种利用微波提供能量在管道内自主移动的微型机器人。之前的一份报告[1]指出，由于执行器的驱动波形是通过微波调幅产生的，因此机器人旋转时无法提供能量，并且供电方法不适合传感器电路。本文提出了一种利用四个整流天线提供圆极化能量的方法。通过在机器人上安装驱动控制电路和红外传感器，成功地实现了自动倒车运动。本文提出的微型机器人以10 mm/s的速度移动，使用直径为15 mm的管道提供200 mW的功率。©2001 Scripta Technica, electronic Comm, 2011,84 (11): 1 - 8,2001
Most robots moving autonomously are equipped with batteries as an energy source. Since the energy stored in the batteries is proportional to their volume, the operating time is drastically reduced as the robot is miniaturized. To resolve this problem, it is necessary to supply energy externally. Considering the checking of pipes in electric power generating stations as the target, a microrobot has been developed that autonomously moves inside the pipe with energy supplied by microwaves. A previous report [1] noted the problems that the energy could not be supplied when the robot is rotated and that the power supply method was not suitable for the sensor circuit, since the driving waveform of the actuator was produced by amplitude modulation of the microwaves. In the present paper, a method is proposed to allow the supplying of energy with circular polarization by means of four rectennas. Autonomous reversing motion is successfully achieved by installing a driver control circuit and an infrared sensor on the robot. The microrobot proposed in this paper moves at 10 mm/s, using a power of 200 mW supplied in a pipe with a diameter of 15 mm. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 84(11): 1–8, 2001
