Built Prototype of ai integrated smart injector.

The Smart Automated Syringe Injector is a microcontroller-based medical prototype designed to deliver controlled and precise injections using an automated mechanism. The system integrates sensing, control, and actuation to eliminate manual intervention and improve accuracy during injection procedures.
An ultrasonic sensor is used to detect the distance between the device and the target surface, enabling real-time depth estimation. Based on this measured depth, the ESP32 microcontroller calculates the required travel distance and dynamically adjusts the speed of the syringe movement. This ensures that deeper targets are reached with higher speed, while maintaining precision.
The ESP32 processes sensor data and generates control signals for the A4988 stepper motor driver, which drives a NEMA 17 stepper motor. The motor rotates a threaded rod mechanism, converting rotational motion into linear motion that pushes the syringe plunger. This enables accurate and repeatable injection.
An OLED display provides real-time feedback, including distance, depth, operational state (scanning, injecting, returning), and system status. Once the target is detected and locked, the system automatically performs the injection, pauses briefly, and then retracts the syringe to its initial position. After a defined interval, the system resumes scanning for the next target.
This project demonstrates the integration of embedded systems, sensor-based feedback control, and electromechanical actuation to create a low-cost, automated medical assistance device. It has potential applications in controlled drug delivery, minimally invasive procedures, and assistive healthcare technologies.
