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 ...

In-hand forward and inverse kinematics with rolling contact

Robotica, 2017
SUMMARYRobotic hands use rolling contact to manipulate a grasped object to a desired location, even when the finger and the palm linkage mechanisms lack degrees of freedom. This paper presents a systematic approach to the forward and inverse kinematics of in-hand manipulation.

Design and forward kinematic analysis of a robotic snake

Proceedings of International Conference on Robotics and Automation, 2002
In this paper a new kind of robotic mechanism is proposed to be used for inspection tasks in complex setups of industrial plants. The shape and motion capabilities of biological snakes are adopted as generic design guidelines. We propose a multi-articulated mobile robot, with a body consisting of repeating modules, capable for both moving efficiently ...

Forward kinematic model for continuum robotic surfaces

2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012
In this paper, we consider the modeling of robotic continuous “continuum” two-dimensional surfaces. We discuss the fundamental differences between such robot surfaces and traditional rigid link and continuum robots. We then introduce new kinematic models for continuum robotic surfaces.

An Method for Forward Kinematics of Stewart Parallel Manipulators

2008
A general 6-DOF parallel manipulator has 40 solutions to forward kinemantics, but most of them are in imaginary domain. This paper presents a simple numerical method for forward kinematics of a general 6-DOF parallel manipulators, which can generate a unique actual solution directly.

Forward Kinematics for a Parallel Platform Robot

2011
This paper proposes a method to calculate the forward kinematics of parallel link manipulators. We calculate the forward kinematics numerically. The method is simple and can make the computer program easy to write.

Analytical Forward Kinematics for Two Kinds of Typical Tripods Part II: Analyzing for Their Workspaces, and Performances of the Forward Kinematics

2012
The 3- P VPHS and 3- P VSP parallel mechanisms (where P, R, and S standing for prismatic, revolute, and spherical joints, respectively, and the subscripts V and H indicating that the direction of the P joint is vertical or horizontal, and the joint with underline symbol means the joint is active) are two typical mechanisms that can be applied to ...

A Forward Kinematics Data Structure for Efficient Evolutionary Inverse Kinematics

2017
Various approaches to solving inverse kinematics implicitly rely on computing forward kinematics in order to obtain an approximate solution. This work proposes an optimised data structure to efficiently compute these equations by avoiding redundant transformations and calculations.
