Advanced Mechatronics Laboratory
High Precision Machines
Ultra-precision machines with nano-level accuracy are the state-of-the-art technology of the mechatronics system. In our laboratory, we develop high-precision systems that are required in various industries such as stages or weighing systems optimally for each application.
High-precision motion stages
Ultra-precision stages for cutting-edge manufacturing such as semiconductors/displays
Optimal mechanism design in consideration of actuator or sensor characteristics
Precision control system design for high bandwidth and multi degrees of freedom control
High-precision mass measurement system
Magnetically levitated weighing system
Extremely low negative stiffness : improves weighing sensitivity and helps the system settle rapidly
Gravity compensation ability : Compensates system dead-weight while maintaining low stiffness
High ruggedness : do not fracture from overweight or impacts from external environment
Ultra-precision weighing cell for Kibble Balance
Weighing cell unit for KRISS Kibble Balance
Axis Symmetric structure with double parallelogram and lever amplification mechanism
Insensitive to parasitic forces and ground tilt : improves measurement accuracy
Fiber Positioner for Multi-Object Spectroscopy
Multi-object spectrograph: A telescope system designed to study the interplay between cosmic expansion and galaxy evolution
Design of robotic fiber positioners optimized for galaxy observation
Development of path planning algorithms to prevent collisions between positioners and enable precise movement to observation targets
