From the hardware side, I designed reliable driver interfaces, power stages, and protection circuits. I also addressed EMI/EMC issues and ensured robust operation under electrical noise conditions. The final solution included full integration with higher-level systems (such as PC applications or indust

Motor Control

I designed and implemented advanced motor control systems for various applications, including servo motors, stepper motors, and DC motors. The system was built around embedded microcontrollers (such as STM32), where I developed real-time control algorithms to achieve precise position, speed, and torque control. I implemented control methods such as PWM-based speed control, closed-loop feedback (using encoders or sensors), and step/direction signal generation for servo drivers.

I developed an interactive motion control system for an entertainment device using a motor-driven model horse, fully integrated with a PC application. The system receives real-time control data from a PC application via serial (USB/UART) communication. Based on this data, an embedded controller (STM32) processes motion commands and drives multiple actuators using step/dir signals or motor drivers. The mechanical motion of the model horse is controlled across multiple axes, enabling synchronized and dynamic movement. I implemented real-time control logic, ensuring smooth motion transitions, low latency, and stable operation. On the PC side, the system was integrated with software (e.g., telemetry-based applications like SimHub or custom software) to visualize and control motion behavior. This allows real-time interaction between the virtual environment and the physical system. The project included full hardware design (PCB for controller and interfaces), firmware development (RTOS-b
