Precision Measurement and Robotics Lab
Machine-translated · View original
The lab brings precision optical measurement technology to manufacturing.

AboutAbout the lab
Precise measurement with light, for the manufacturing floor
The Precision Measurement and Robotics Lab studies precision measurement and control that contribute to mechanical engineering, especially production engineering and machining.
The lab develops its technologies along the flow of making, measuring, and using micro-scale fine patterns, and builds ultra-high-sensitivity optical angle sensors and sensors that use optical frequency comb lasers.
In robotics, the field named in the lab's title, the lab also works on structural analysis and control of robots, as well as dynamic characteristics analysis and motion control of mechanical systems.
The lab is relatively new, having been established in autumn 2021.
Key terms
- Precision measurement
- Technology for accurately measuring lengths, angles, and other quantities at a level of fineness that ordinary rulers cannot reach
- Optical frequency comb laser
- A laser whose light consists of evenly spaced frequencies lined up like the teeth of a comb. It can be used as a reference for length and distance
- Angle sensor
- A device that measures the angle of an object's tilt or rotation. It is used for positioning in machine tools and optical instruments
