Three ATA-2042 high-power amplifiers are connected to the output of the microcontroller chip and the five coils of the electromagnetic coil system. Instructions sent from the host computer are amplified by specific factors through the amplifiers to control the electromagnetic coil system, generating magnetic fields of specific strength and frequency via electromagnetic effects. The high-power amplifiers are suitable for our high-resistance coils, ensuring effective and timely signal response. Different amplification factors are applied to accommodate various modes, such as gradient magnetic fields and uniform magnetic fields. By placing the photopolymerized magnetic control robot at the center of the electromagnetic coils, it can effectively respond to magnetic field control for motion.

Experimental Results: As shown in Figure 3, by controlling the position of the iron core in the electromagnetic coil system and adjusting the input voltage intensity via the amplifiers, gradient magnetic fields and uniform magnetic fields can be effectively generated. The rapid response of the amplifiers to signals from the host computer enables flexible control of magnetic field modes in the electromagnetic coil system. Figure 4 depicts photopolymerized crawling multi-legged robots and flying butterfly robots. Under the high-frequency signals output by the amplifiers, the electromagnetic coils can rapidly change the direction, frequency, and strength of the magnetic fields. The crawling robots achieve coordinated multi-directional control of their legs for crawling motion and posture adjustments, while the butterfly robots accomplish wing flapping.
