Scanners, Robots, Measurement Plans – Synergy in Motion





Motivation  Metrology Solution

 Lidar Scanner

• Target-less Technology  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: Lidar Scanner

 Simple Automation: Programmable part

and tool feature inspections, alignments,

reports, initiate programs remotely

 Accuracy: 65 mm at 10 m

 Surface/Feature Measurements:

• MV200 requires only 1 pico-watt (10-12W) of

return signal  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  Target-less  Features

 No Photogrammetry Dots

 No Laser Tracker SMRs

 No Retro Reflectors

 No Probes

 No Contact

Component 2: Robot

 Reliable 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: Integration Software

 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

 One interface controls and

coordinates the system

components

 Extrinsic Calibration through In-

line Robot Control Model:

• Tool to CLR Frame

• Robot Base to WORLD

 Integrated graphical automation

programming for n systems

 Distributed computing

 Remote monitoring and control

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

• Etc…

 Integrated robot performance enhancements

(feedback / calibration loop)
