Labeling Experience

Design, Modeling, Simulating, and Prototyping of R2P Robotic Arm with Adaptive Gripper for Automated Hazardous Chemical Sorting Assisted With Computer Vision

ImageObject Detection
I co-designed and developed a SCARA robotic arm with an adaptive gripper and integrated computer vision to identify and sort hazardous chemical containers. The system was programmed to autonomously detect labeled containers and perform pick-and-place operations. I worked extensively on enabling the robotic gripper to handle containers based on CV-driven label detection. • Labeled images of chemical containers for training vision algorithms • Integrated computer vision with robotic control for automated object detection • Designed adaptive gripper to respond to visual label information • Enhanced robotics automation through real-time visual feedback loops

Computer Vision-Based Object Width and Class Detection for Hazardous Chemical Sorting

ImageClassification
I designed and implemented a computer vision system to automate the sorting of hazardous chemical containers using image-based classification. The project required developing label recognition functionality utilizing CNN-based image classification techniques. I created a CV pipeline for hazard symbol identification and dimension estimation of containers for robotic sorting. • Built and deployed labeled dataset of hazardous chemical symbols for classification • Developed and tested CNN model for hazard symbol recognition • Integrated OpenCV and Python for image preprocessing and object detection • Synchronized classification output with robot gripper’s control logic for real-time automation
