iAR Lab Research Direction


1. Mechatronics


Portable self-tunable device

  • Motivation: Need vibration suppression of systems with dynamic variance such as machine tools, robots
  • Challenge: Target-frequency change, MIMO system
  • Goal: Develop a self-adjustable, multi-axis vibration suppression device

2. Intelligent automation

Cutting force measurement (funded by KIMM)


  • Motivation: Need to measure clamping force and cutting force
  • Challenge: Embedding sensors, Decoupling Force, dynamic compensation 
  • Goal: Develop a smart-vise device
  • Collaborating with Dr. Park

Low-cost and high-accuracy position tracking system (funded by URGC) 


  • Motivation: Need a high-accurate and low-cost tracking device 
  • Challenge: signal drift, tilted local coordinates, and low static/dynamic accuracy
  • Goal: Develop a tracking system based on VR tracker

3. Robotic manufacturing


Cable assisted robotic system

  • Challenge : 50 times lower structural stiffness than that of CNC machine tools
  • Novelty: Installing an optimal configuration of cables at the robot/ Controlling the cable to track the robot’s movement
  • Outcome: 5~10 times stiffness improvement , Milling steel using the robot
