Kinematic Design of a Tripod Parallel Mechanism for Robotic Legs

2017
In this paper a parallel manipulator with tripod architecture is proposed with the closed-form formulation of its functioning. The mechanism is 3-Degrees-of-Freedom manipulator that can be used as robotic leg for mobile walking robots with two or more legs.

Design of an Ankle Rehab Robot With a Compliant Parallel Kinematic Mechanism

Journal of Mechanisms and Robotics, 2020
Abstract In this article, we present the design of a novel ankle rehabilitation robot (ARR), called the Flex-ARR, that employs a compliant parallel kinematic mechanism (PKM) with decoupled degrees-of-freedom. While multiple ARRs have been developed and commercialized, their clinical adoption has been limited primarily because they do not

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 ...

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.

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 ...

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.

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.

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 Alternative Robotic Mechanical Systems

2014
The study of robotic mechanical systems has focused, so far, on serial manipulators. These are the most common systems of their kind, but nowadays by no means the majority. In recent years, other kinds of robotic mechanical systems have been developed, as outlined in Chap. 1. Under alternative robotic mechanical systems we understand here: (a) parallel
