Haptic welding trainer on a 5-bar pantograph - two Arduino-driven motors render force/vibration feedback while an openFrameworks app draws the weld bead, arc, and sparks in real time.

Pantograph Detection is a Python script using YOLOv8 to detect pantographs, pantobars, and cables in video. It tracks movement, calculates contact points, and logs data to a CSV file, while also saving an annotated output video.
