Scanners, Robots, and Measurement Plans

Motivation

• Metrology Solution
• MetricVision Scanner
  • Target-less Technology à Feature based measurements
  • Ideal for unattended and automatic inspection
  • Need to automatically reposition to scan entire object (ex: Car)
• Metrology software system architecture required to integrate the measurement system, CAD design, and robotic manipulator
• Measurement Plan capability required to automatically acquire and analyze the data
• It’s Cool !!

Component 1: MV Scanner

• Simple Automation: Programmable part and tool feature inspections, alignments, reports, initiate programs remotely
  • Accuracy: 0.065 mm at 10 m
  • Surface/Feature Measurements:
  • MV200 requires only 1 pico-watt (10-12W) of return signal à any surface
  • Fast: 1,000 measurements per second
  • Versatile: Used in varied configurations
• Portable independent measurement system
• Part of an automated robotic metrology system
• Non-contact à Target-less à Features
  • No Photogrammetry Dots
  • No Laser Tracker SMRs
  • No Retro Reflectors
  • No Probes
  • No Contact

Component 2: Fanuc Robots

• Reliable FANUC Robot for handling
• Long reach
• 2.1 times more with Flip Over Mechanism
• Variety of layouts
• A simple motor direct drive mechanism
• Minimizes the interference area
• Small/slim wrist allows the robot to operate in a small space
  

Component 3: SpatialAnalyzer

• Programmable measurement planning with dynamic real time graphical interface
• Distributed computing capable (real-time multi-task measurement and analysis across multiple computers)
• Instrument compensation
• Synchronous Measurement between Instruments (Master-Slave or Synchronous Polled Modes)
• TCP/IP interfaces to instruments to enable distributed processing
• Supports remote process control and monitoring.
• Common instrument user-interface

System Integration

• Adaptive Scanning In Action
• Adaptive Scanning: Close-up

Benefits / Applications

• Increased workspace for metrology equipment by extending visibility
• Integrates reliable hybrid technologies on a common platform through general object oriented architecture
• Adaptive Automation improves process reliability
  • If the system can’t quite see the feature it can be programmed to interactively hunt it down
• Custom configurations fit the application
  • Robot moves instrument
  • Robot move the part
• Adaptive control
  • Integrated robot performance enhancements (feedback / calibration loop)
