- 01ROS 2 Based Face Tracking Display Control with PiPER Robotic Arm
0.Introduction This project demonstrates a vision-based smart ergonomic workstation built with an AgileX PiPER 6-DoF robotic arm, Orbbec RGB-D camera, and ROS 2. Using YOLOv5-Face and depth perception, the system detects the user’s 3D position and controls the robotic arm to adjust the display orientation automatically. Safety Considerations This prototype does not include certified safety functions, such as collision detection, human safety monitoring, speed monitoring, or emergency stop contro

Hi everyone, I’m a PhD student, and after a few years my codebase has grown quite a bit, spread across different git repos, Docker containers, and machines. I knew it would be good to add some tests to avoid regressions and losing work or features. However, writing unit tests alone as a student would probably cost me another year of my PhD. So instead I went for integration tests, which are easier to write in a ROS environment and make more sense for a pipeline where the internal functions keep
