The aim of this article is to create a system that enables power transmission non-backdrivability in a hand prosthesis with a single actuator. This system allows the motor to be stopped while maintaining the gripping force to prevent the held object from being dropped. This non-backdrivability allows users, for example, to release muscle contractio...
The main objective of this thesis is to present an accessible myoelectric hand prosthesis that combines criteria such as affordability, durability, functionality, and performance. This new prosthesis allows for both lateral and opposing grips. Firstly, we propose a method for joint placement that achieves a more realistic anthropomorphic result. Ad...
This work introduced a new hand prosthesis architecture able to achieve an opposite and lateral grasp by using a single actuator. An analysis of the hand prostheses, as well as the movements classically performed in daily life and at work allows us to focus our work on these two types of grasp. A lockable passive joint is moved by the user to switc...
This work proposes a new kinematics of a myoelectric hand prosthesis with a single actuator, allowing to realize the tridigital grip but also the lateral grip. Inspired by tridigital prostheses, which are simpler, more robust and less expensive than polydigital prostheses, this new kinematics aims at proposing an accessible prosthesis (affordable,...
This work proposed the design of a simple, robust and inexpensive motion transmission for hand prostheses. The main challenge to be solved is to generate not only fast movements for the closing of the fingers during the grasping but also important forces to hold these objects. A Two-Speed Load Adaptive Variable Transmission is introduced to solve t...
This work studies redundant actuation for both trajectory tracking and disturbance rejection on flexible cable-driven parallel robots (CDPR). High dynamics/bandwidth unidirectional force generators, like air propellers, are used in combination with conventional but slower cable winding winches.
To optimally balance the action of the two types of a...
