Fault-Tolerant Six-DoF Pose Estimation for Tendon-Driven Continuum Mechanisms
2021
Frontiers in Robotics and AI
Preserved Fulltext
We propose a fault-tolerant estimation technique for the six-DoF pose of a tendon-driven continuum mechanisms using machine learning. ...
In contrast to previous estimation techniques, no deformation model is required, and the pose prediction is rather performed with polynomial regression. ...
The specific contributions, which also define the structure of the paper, are: • A data-driven approach for real time six-DoF pose of tendon-driven continuum mechanism using few data points. ...
