On the Kinematic Analysis of Robotic Mechanisms

The International Journal of Robotics Research, 1999
The kinematic analyses, of manipulators and other robotic devices composed of mechanical links, usually depend on the solution of sets of nonlinear equations. There are a variety of both numerical and algebraic techniques available to solve such systems of equations and to give bounds on the number of solutions. These solution methods have also led to

Kinematic Dexterity of Robotic Mechanisms

The International Journal of Robotics Research, 1994
In this article we develop a mathematical theory for optimizing the kinematic dexterity of robotic mechanisms and obtain a collection of analytical tools for robot design. The performance criteria we consider are workspace volume and dexterity; by the latter we mean the ability to move and apply forces in arbitrary directions as easily as possible ...

Kinematics of Robot Mechanisms with Closed Actuating Loops

The International Journal of Robotics Research, 1990
The kinematic properties of multiloop chains for robot appli cations are investigated using a structure-based approach. The basic concepts related to algebraic groups of displace ments and to Assur's groups are used in order to provide systematic foundations for analysis and synthesis procedures. Analysis techniques are described, and several examples

Kinematic Calibration of Robotic Mechanism

2020
Accuracy is the primary concern in the application of robotic mechanisms because it directly affects the performance and capability of the robots [1, 2]. The main source of errors affecting the robot accuracy is due to the deviations between nominal and actual kinematic parameters.

Robot Wrist Configurations, Mechanisms and Kinematics

1994
This paper discusses a general method for determining the kinematic performance of spherical robot wrists. Different wrist types considered include R-P-R (roll-pitch-roll) and P-Y-R (pitch-yaw-roll) wrists. Singularity conditions are indicated for both cases. For R-P-R wrists, singularity is defined by the ratio of the angular velocity of each motor to

Mechanical design and kinematic analysis of the AH1N1 humanoid robot

CONIELECOMP 2011, 21st International Conference on Electrical Communications and Computers, 2011
In this paper the mechanical design and kinematic analysis of a humanoid robot are presented. This robot is designed to perform as a soccer player, according to the current structure and dimensions restrictions stated by the International RoboCup Federation for the Kid-Size league in the RoboCup competition.
