Voice coil for actuation of a spherical mechanism

A two-degree-of-freedom tilt/tilt mechanism for aerospace applications requires an actuation and a voice-coil type design has been selected. The goal of the project is to dimension, fabricate and test the voice-coil actuator.


To be done during the project:

  • dimensioning of the iron-core, magnet and winding
  • fabrication of the iron-core and winding
  • fabrication of a test bench and characterisation

Required background:

  • knowledge in electromechanics
  • concept of flexure mechanics

Flexure fly wheel

Master project consists of :

A flexure mechanism allowing circular motion has been developed theoretically, but has not yet been experimentally validated. The project goal is to validate the concept with a proof-of-concept prototype.

To be done during the project:

  • design and dimensioning of the test bench
  • fabrication and testing of the demonstrator (through 3D printing, laser cutting,..)
  • if enough time is available, replacement of the wheel of a model steam engine by the demonstrator in order to show their equivalence.

Required background :

  • Mechanical design
  • Concept of flexure mechanics

Bistable gripper (Already taken)

GripperGrippers are commonly used in robotics to grab and deliver parts at a precise location. In the medical domain, grippers are used as surgical tools for example. However, it is difficult to scale them down to a few millimeters due to tolerances of manufacturing and assembly. Fabricating a gripper based on flexure and bistable mechanics could be a solution and brings multiple other advantages and applications.

Project consists of :

  • Kinematics design of the gripper
  • Prototype design, fabrication and testing

Required background :

  • Mechanical design
  • Concept of flexure mechanics

Micro surgical saw (Already taken)

Medical SawThe aim of the project is to design several types of surgical saws which can be miniaturized to be used during precise medical operations. A powered rotary oscillation to a specialized cutting implement should be applied to provide smooth controllable cuts into tissues or bones. The kinematics of the saw guidance has to be designed and could be partially or entirely realized with flexure elements.

Project consists of :

  • Kinematics design of the saw guidance
  • Actuation system design
  • Prototype design, fabrication and testing

Required background :

  • Mechanical design

Flexure based surgical tool

Growing life expectancy goes together with improvement of healthcare. New threatment methods are becoming less invasive, allowing for shorter recovery time. Following this trend we would like to propose a new micro-surgical tool.

Project will focus on development of flexible structure for flexture based surgical tool. It will allow for 2DoF of rotations. End effector integrated in such flexure will be a gripper, or other depending on medical application.

Whole structure should be open for either manual or robotic actuation.
