Nonlinear contact and impact of revolute joints

2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012
The contact deformation model of revolute joint is established based on Hertz theory, and the simulation model is developed based on finite element method (FEM). The results obtained from two models are compared. The error of Hertz model is evaluated by comparison with corresponding FEM, which changes with the contact depth and the clearance of ...

A study of manipulator with passive revolute joint

Artificial Life and Robotics, 2008
In this article, equations of motion of a manipulator, whose mechanism has a passive revolute joint, are derived in consideration of the characteristics of driving source. Considering the fi nal condition of displacement and velocity of the passive joint, trajectories of velocity for energy saving are calculated by iterative dynamic programming.

A tactile sensor system for revolute joints of manipulators

IEEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications, 2002
Deals with a tactile sensor system for revolute joints of manipulators in order to detect contacts with obstacles. It has the ability to detect, in a sampling period, more than one location of contact switches which are turned ON even on a signal line.

A Novel Reconfigurable Revolute Joint with Adjustable Stiffness

2019 International Conference on Robotics and Automation (ICRA), 2019
In this paper, a novel revolute joint of adjustable stiffness with reconfigurability (JASR) is presented. The JASR is designed with zero-length base link four-bar linkage, and allows adjusting its stiffness to achieve soft-and hard-spring behaviour. The new joint has a compact and light-weight structure and can be integrated in robot and transmissions ...
