Forward Kinematics of Casing Oscillator

IEEE/ASME Transactions on Mechatronics, 2006
This paper presents the forward kinematics of the casing oscillator, which is a heavy construction machine. This machine has a four-degrees-of-freedom (DoF) parallel mechanism with one redundancy. By using the geometric approach, the forward position kinematics for the casing oscillator is derived as a fourth-order polynomial equation in square form of

On the Forward Kinematics of Parallel Manipulators

The International Journal of Robotics Research, 1994
In this article we present a novel procedure for the system atic analysis of the forward kinematics of a class of parallel manipulators that generalize the well-known Stewart plat form. The designs comprise a movable platform connected to a fixed base by a set of legs, the lengths of which can be con trolled.

Forward and inverse kinematics of a robotic frog

2012 4th International Conference on Intelligent Human Computer Interaction (IHCI), 2012
Among all the kinds of locomotion adapted by the living organisms in nature, jumping has proven itself as one of the most efficient ways of traversal through rough terrain. Frogs are the efficient and stable organisms which use jumping as their primary means of locomotion.

On the forward kinematics of cable-driven parallel robots

2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015
Most cable-driven parallel robots are kinematically over-constrained mechanisms. This results in a non-trivial computation of the forward kinematic transformation. It is well known that the forward kinematics of parallel robots may have multiple solutions and in general the convergence of numerical methods is unknown.

The Forward and Inverse Kinematics of a Delta Robot

2020
The Delta robot is one of the most popular parallel robots in industrial use today. In this paper we analyse the forward and inverse kinematics of the robot from a geometric perspective using Conformal Geometric Algebra. We calculate explicit formulae for all joints in both the forward and inverse kinematic problems as well as explicit forward and ...

Bounds on the derivatives of the forward kinematic map for open-kinematic-chain manipulators

Proceedings, 1989 International Conference on Robotics and Automation, 2003
The authors develop simple, configuration-independent bounds for the Jacobian and the higher order derivatives of the forward kinematic map of a manipulator with revolute and prismatic joints. In doing so they obtain: a simple formula for the higher order derivatives of the forward kinematic map; an easily computable and meaningful metric on the group ...

Forward Kinematic Analysis of Kinematically Redundant Hybrid Parallel Robots

Journal of Mechanisms and Robotics, 2020
Abstract This paper focuses on the forward kinematic analysis of (6 + 3)-degree-of-freedom kinematically redundant hybrid parallel robots. Because all of the singularities are avoidable, the robot can cover a very large orientational workspace.

Learning Forward and Inverse Kinematics Maps Efficiently

2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
When learning forward and inverse kinematics maps of manipulators, usually little attention is paid to data-efficiency, i.e., the accuracy gained per action-outcome sample. This paper examines properties of popular (online) learning techniques and demonstrates that - regardless of the employed exploration strategy - the structure of kinematics mappings

A study of kinematic models for forward calibration of manipulators

Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003
The objective of robot calibration is to identify all parameters in a robot model so that the model represents the true robot. Each model has its own set of parameters. The authors prove that regardless of the kinematic model chosen, there are a maximum number of parameters that must be determined, implying that model accuracy cannot be improved by ...
