Three ATA-2042 high-power amplifiers are connected to the output end of the microcontroller chip and the five coils of the electromagnetic coil system. Instructions sent from the host computer are amplified by a specific multiple through the amplifiers to control the electromagnetic coil system. This generates a magnetic field of a specific intensity and frequency. The high-power amplifiers are suitable for our high-resistance coils and provide effective and timely responses to signals. Different amplification multiples are used for gradient and uniform magnetic fields. Placing the photo-polymerizable magnetic robot at the center of the electromagnetic coil enables effective magnetic field response and movement control.

Experimental Results: As shown in Figure 3, by controlling the position of the core in the electromagnetic coil system and the input voltage intensity via the amplifier, gradient and uniform magnetic fields can be effectively generated. The amplifier's fast response to host computer signals allows the electromagnetic coil system to flexibly control magnetic field modes. Figure 4 shows the crawling multi-legged robot and the flying butterfly robot made by photo-polymerization. Under the high-frequency signals from the amplifier, the electromagnetic coil can quickly change the magnetic field direction, frequency, and intensity. The crawling robot can achieve multi-directional coordinated control of its legs for crawling and posture adjustment. The butterfly robot can achieve wing flapping.
