Robotic arm


Brief Description: The 6dof robotic arm is a mechanical arm with 6 independant controlled rotating joints mounted on a platform. At the end of the arm different tools can be mounted.


This experimental robot arm is used to investigate and apply control concepts for robotic arms. Each joint can be controlled separately. Topics for investigation are

  • LPV-Control
  • Robust Control
  • System identification
  • Hybrid Position and Force control
  • imitation and reinforcement learning algorithms.
