Dan is currently taking part in an Industrial Ph.D project in collaboration with Universal Robots A/S and Aarhus University, Department of Engineering. He has been enrolled at Aarhus University based on his Bachelor and Master degree in Mechanical Engineering. His Master Thesis was conducted in collaboration with Fertin Pharma, and dealt with dynamic modeling of industrial robot arms.

Project title:
Vibration analysis and control of UR robot manipulators with the consideration of link and joint flexibility

Project description:
Universal Robots develops and manufactures collaborative robots. Collaborative robots have a high safety level that makes human-robot collaboration possible, and the robots are meant to work alongside humans as coworkers. Universal Robots strives to improve its products in productivity, precision and versatility.

This project intends to improve all these points by an effective reduction of mechanical vibrations in the robots. All electromechanical systems experience vibrations and when compared to the conventionally heavy industrial robots, collaborative robots are sensitive to vibrations due to light weight structures.

The improvements are to be obtained by precise dynamic modelling of mechanical deflection in the robot. This dynamic model will be used to slightly change the behaviour of the robot for reducing induced vibrations. This approach is preferable because it will be possible to implement it in all existing and future robots and it is only a software concern.

Project period: July 2016 to June 2019
