Creativity: OpenFPT is a dual-arm robotic probing platform designed for automated PCB electrical evaluation. The system employs two planar 2-DOF robotic arms based on 5-bar parallel linkage mechanisms, controlled by an ESP32-C6 microcontroller. Each arm positions a metallic probe over target test points on a PCB board. After positioning, dedicated probe actuation servos lower the probes to make physical contact with the board, and the system performs electrical measurements including continuity testing, isolation checks, and signal path verification. The platform integrates an AI-powered host software stack that automatically generates test plans from KiCad design files and provides LLM-based fault diagnosis from measurement results.
