‘STIFF-FLOP’ is a flexible manipulator of controlled rigidity, capable of learning, used for performance of surgical procedures (Stiffness controllable Flexible and Learn-able manipulator for surgical Operations).

Project purposes:

The goal of the project is to build an innovative soft robotic arm that will be able to: 

  • Pass through a standard port for low-invasive surgery (approx. 12-20 mm diameter);
  • Change its configuration including rigidity (controlled hydrostatically) for correct operation, also after occurrence of an expected situation in the environment of the arm.

The project will build a complete system consisting of the following:

  • Design and fabrication of a soft arm with a gripper;
  • Distributed sensor system;
  • Biologically inspired system of interaction and control;
  • System of learning by interaction with the operator;
  • System for manipulation of objects in complex and uncertain spaces.

The project proposes a solution for robotic laparoscopic surgery that faces the problem of restricted access via trocar and operation in space filled with body organs.
