Abstract

The device uses a self-made electromagnetic cannon and a control charging and discharging circuit to constitute the launching device of the electromagnetic cannon. The two-degree-of-freedom control PTZ controls the angle and direction of the electromagnetic cannon. It uses dual power supplies to power the main control board and electromagnetic cannon device. The microprocessor STM32F407 is used as the control core of the electromagnetic cannon, and the TCA8418 IIC matrix keyboard is used to adjust the distance and angle. The OpenMV4 automatically searches for the guide mark and captures the image shape and color blocks in real time to control the electromagnetic cannon to hit the round bullseye. . In addition, it also uses Lidar to measure the distance between the calibration point and the ring target, and uses OpenMV4 to realize the automatic search and launch of the electromagnetic cannon.
