Collaborative Robot

-Research Background

  • Various tasks for service to humans are required for collaborative robot.
  • A multi-DOF manipulator is needed for dexterous manipulation.

- Research Objectives

  • Development of a multi-DOF collaborative robot
  • Compact and lightweight design

- Simulation and design of collaborative robot

  • Dynamic simulation: torque and moment load of each joint
  • Manipulability analysis: operation angle of each joint
  • FEM analysis: lightweight structure


- Research Output

- Features for KUDex series

* Collision Detection & Reaction

  • Highly sensitive collision detection using JTS   
  • Collision detection with payload and during tasks

* Easy Teaching

  •    Graphical programming (icon-based)  
  •    Direct teaching (no programming required)

  * JTS-based Force Control

  •    Estimation of external force/torque acting on the end-effector (FTS emulation)
  •    Impedance control/Admittance control
  * Lightweight & Modular Design
