PROFILE
Jack-crowley
During two months on the purdue-arc/sphero-swarm repository, James Crowley developed and enhanced real-time perception and tracking systems for robotics applications. He integrated YOLOv8-based object detection with DepthAI for live camera feeds, enabling consistent object tracking and flexible data ingestion through argument parsing and stream abstraction in Python. James improved reliability by fixing thread synchronization issues and reorganizing code for maintainability. He also implemented grid-based arena visualization, latency instrumentation, and a simulation environment to support safer testing and faster debugging. His work included robust server-client communication, comprehensive documentation, and enhancements that accelerated onboarding and integration with external perception pipelines.
