Design of Handheld PTZ Stabilizer Based on Arduino

The handheld stabilized PTZ can eliminate the change of PTZ’s attitude caused by the user’s movement relative to the external environmental parameters. The PTZ stabilizer can enable the object on the carrier platform to achieve attitude stability control, which can automatically keep the camera, mobile phone and other devices stable and balanced during the shooting process, so that the captured images are clearer and the picture quality is better. In this paper, a low-cost, multi-functional, low energy consumption three-degree-of-freedom handheld PTZ stabilizer is designed to solve the problems such as picture shaking of small handheld devices when in motion. The IMU component of the MPU 6050 is used as the angle detection component of the handheld PTZ stabilizer. The Arduino Nano MG996R is used as the microcontroller to process the collected data into angle data, and the PWM signals are outputted by the pins to control the steering gears. The Blender software is used to model and design the 3D model of the PTZ shell, and the Arduino is used to integrate the PTZ control software and hardware, and finally the overall design is optimized. The experiment shows that the design meets the requirement that the carrier coordinate system is stable relative to the geographical coordinate system. Although there is a certain angle error, the overall operation is in good condition. At the same time, it can also suppress the output of a certain axial direction to achieve the function of a two-degree-of-freedom handheld PTZ stabilizer.
