Smart Load Carrier

My project, Smart Load Carrier is a QR code enabled load carrier with automated tracking that follows designated QR codes, showcasing its designed functionality for autonomous load transportation. The carrier system with a robust carrier mechanism is equipped with sensors and communication modules and interprets QR codes, enabling autonomous navigation.
The Smart Load Carrier is constructed on a sturdy metal body and employs an L298 motor driver for precise controls of the motor. It is guided by Raspberry Pi, ensuring precise execution of commands. The device incorporates a webcam for Image Processing through a Raspberry Pi, enabling seamless navigation and detection of QR codes. With a carrying capacity of 5 kilograms, the prototype is well-equipped to carry out tasks effectively and efficiently.
I employed Python for real-time QR code identification in camera video streams. I was able to successfully integrate with the OpenCV python library, which is a computer vision package containing methods to assist users in manipulating and analyzing images. I wrote a detect_qr_code function that converts each frame to grayscale, uses the Gaussian mean for adaptive thresholding, and detects QR codes. With its clever handling of both rectangular and non-rectangular QR codes, it showcases its versatility in identifying their locations (e.g., top-left, center, or bottom-right), calculating the center points, and outlining the codes with green rectangles.
Under the guidance of my mentors, I designed the system requirements and functionalities of the device. I developed a QR code recognition algorithm and integration with the carrier’s control system. I applied image processing skills to create an algorithm capable of efficiently decoding QR codes. Optimizing the carrier’s autonomous navigation system, I ensured seamless and accurate movement. Furthermore, I engaged in testing and refining the system by accessing efficiency, error rates and overall operational improvement of the load carrier.
