Automated Pop-Up Target System for Rifle Shooting Trainee
As a member of a Bangladesh Army team, I developed an Automatic Pop-Up Target System designed to enhance soldiers' firing practice. This system enabled dynamic and automated training, integrating various features to streamline and improve the training experience. Key technical contributions included:

• Funding: 31,000 USD awarded for prototype development.
• Automated Target Mechanism: Designed a rise-and-fall mechanism using servo motors and electrical actuators, allowing targets to automatically pop up and reset.
• Real-Time Hit Signaling: Implemented SMS and radio signal transmission upon target impact, providing immediate feedback for enhanced training accuracy.
• Hit Counting and Display:>
• Precision Bullet Impact Analysis: Employed vibration and gyro sensors, alongside custom signal processing, to accurately detect hits and prevent false-hit signals.
• Microcontroller-Based Control>:
• The project received $20,000 in funding from the military, was successfully completed, and has been finally handed over for industrial fabrication and operational use. This experience underscores my skills in embedded systems and sensor integration, aligning well with my PhD research interests in automation and control systems.
