Guiding Robotic Arm to Calibrate LASER Pointers in LIDAR system
Multiple camera & borescope based CV solution was used to automatically guide a robotic arm to grab highly compact PCB with sub millimeter dimensions from an array of PCB stack and calibrate its position
Results / Outcomes
Automating the calibration process which previously took 1 day using manual methods to few hours.
Robotic arm could identify and grab the PCB safely without damaging the components with micrometer accuracy.
The system could be calibrated with all the space constraints in the final enclosure.
A Borescope vision system was used to access areas inaccessible to regular machine vision cameras
