Design and control of robotic manipulators

The DEXTER team conducts research on design, control, and prototyping of efficient robot manipulators capable of achieving accurate and/or very quick motions, sometimes across wide workspaces and while handling heavy payloads. To reach these challenging goals, each fundamental research activity is validated by realistic experiments, an essential step in the valuation of these results with industrial partners, or with medical surgeons or clinicians.
The research topics addressed by the DEXTER team include methodologies for mechanical design, performance analysis and synthesis for parallel robots, the development of estimation protocols and the synthesis of sensor-based (e.g. force, vision) and/or model-based (e.g. predictive, adaptive) control laws.

The team emphasizes innovation with a strong mathematical modeling and mechatronics approach.

DEXTER’s main contributions are found in two main application areas:

  • Healthcare robotics, from assistive robotics to surgery
  • Parallel robotics for industrial applications requiring high speed, accuracy, large workspace and/or high payloads.
