Structural Properties in Kinematics of Robots, Articulated Mechanisms and Prosthetic Arms

IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 1984
Abstract Kinematics of spatial manipulating systems can be deeply understood and effectively solved introducing structural considerations. The concept of kinematic equation of motion and its canonical form, introduced by the authors, is further developed using moving coordinates and the components of the ‘absolute’ and generalized coordinates vectors

Mechanical Design and Kinematic Control of a Humanoid Robot Face

2019
Faces are very important for human social activities. However, most of the current humanoid robots only have a stiff face. This paper aims at developing a humanoid robot face system can express facial expressions. Bio-inspired by the anatomy of a human head, mechanical structures, including eyebrows, eyes, and mouth, are designed.

Kinematics of a class of hybrid robotic mechanisms with parallel and series modules

Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002
The position and velocity kinematics for a class of 6 d.o.f. hybrid robotic mechanisms is studied. The specific class of hybrid manipulators features a 3 d.o.f. in-series actuated module mounted on a moving platform of another 3 d.o.f. in-parallel actuated manipulator.

Kinematic optimization of a spherical mechanism for a minimally invasive surgical robot

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
Advances in surgical technology allow physicians to more effectively provide care to their patients. Minimally invasive surgery (MIS) has revolutionized the way a significant number of procedures are performed. Advances in technology have led to the fusion of MIS techniques and robotic devices; however, such systems are currently large and cumbersome ...

Dynamic task-priority allocation for kinematically redundant robotic mechanisms

Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'94), 2002
This paper presents a flexible redundancy resolution strategy based on the task-priority method. A dynamic task-priority allocation approach has been motivated by the fact that the performance may degenerate for improper fixed-priority assignment to various task components.

Mechanism Design and Kinematics Analysis of a Bat Robot

2017
This paper proposes a bat robot mechanism and investigates the kinematics of flying process. After observing the flight of bat for a long period of time and analyzing its flying kinematics, a bionic robot was synthesized based on the bat structure to realize the deploying and flapping movements of the double membranous wings.

An approach to symbolic kinematics of multiloop robot mechanisms

2005
The paper presents some topics related to an automatic approach to the generation of symbolic kinematic models of robot mechanisms. The approach applies to direct and inverse kinematics, also in the cases of multiple arms, and can be applied to robot mechanisms made up of drivers and single-loop determined kinematic chains (SLDCs). A robot mechanism is

ARMin II - 7 DoF rehabilitation robot: mechanics and kinematics

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
Task-oriented repetitive movements can improve motor recovery in patients with neurological or orthopaedic lesions. The application of robotics can serve to assist, enhance, evaluate, and document neurological and orthopaedic rehabilitation. ARMin II is the second prototype of a robot for arm therapy applicable to the training of activities of daily ...

Kinematics of Complex Robotic Mechanical Systems

1997
Current robotic mechanical systems, encountered not only in research laboratories but also in production or construction environments, include robotic mechanical systems with features that deserve a chapter apart. Generically, we will call here complex robotic mechanical systems all such systems that do not fall in the category of those studied in ...

Structural Kinematics of Partially-Parallel Robotic Mechanisms

13th Design Automation Conference: Volume 2 — Robotics, Mechanisms, and Machine Systems, 1987
Abstract This paper introduces a new generation of robotic mechanisms. Such mechanisms are intermediate between the familiar serial and the fully-parallel robotic mechanisms. They usually comprise several subassemblies that are serially connected to one another.
