Precision Robot Vision Integration

A major automotive manufacturer needed to integrate high-precision LiDAR sensors with industrial robots for automated welding and component assembly. Their existing vision systems lacked the accuracy for complex 3D parts with varying reflectivity and couldn't maintain calibration during continuous operation.

CalibWorks developed a comprehensive LiDAR-to-robot calibration system that precisely aligns sensor coordinates with the robot's tool center point (TCP). The solution enables real-time 3D perception for adaptive path planning, quality inspection, and collision avoidance in dynamic manufacturing environments.

  • Automatic hand-eye calibration with sub-millimeter precision
  • Real-time coordinate transformation during robot motion
  • Temperature and vibration compensation algorithms
  • Multi-robot coordination with shared LiDAR perception
  • Online calibration verification and drift detection
  • Integration with major robot controllers (ABB, KUKA, Fanuc)
