In situ robotic arm operations
IEEE Robotics & Automation Magazine, 2009This article compares and contrasts the operations of the robotic manipulators on the Mars Phoenix Lander and Mars Exploration Rovers (MERs), Spirit and Opportunity. Unlike the MERs, the Phoenix Mars Lander stays in one spot at a particular geographic location on the Martian surface with exploration emphasis on vertical mobility sampling.

As a first step in control of two-arm robots, it is necessary to determine the kinematic relationships between the two end-effectors at any instant. The elements Of the orientation-position matrix of a dual (slave) arm are obtained in terms of those of the main (master) arm, so that the kinematic equations of each can be individually solved.

The Singularities of Redundant Robot Arms
The International Journal of Robotics Research, 1990A robot arm is redundant if it has extra degrees offreedom. In such cases the kinematic function is a mapping from a higher-dimensional joint space to a lower-dimensional work space. The manipulator may have singular configurations, which are singularities of the kinematic function.

Quantifying anthropomorphism of robot arms
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015In this paper we introduce an index for the quantification of anthropomorphism of robot arms. The index is defined as a weighted sum of specific metrics which evaluate the similarities between the human and robot arm workspaces, providing a normalized score between 0 (non-anthropomorphic artifacts) and 1 (human-identical artifacts).

Behavioral control of a robot arm
Proceedings 1995 Second New Zealand International Two-Stream Conference on Artificial Neural Networks and Expert Systems, 2002This paper describes a novel trainable controller which extends the feedback-error paradigm of Kawato (1987), called an adaptive trajectory generator. The controller can be adapted so that a controlled system shows a behavior which is specified using heuristic rules. The training algorithm is simple and computationally inexpensive. Its effectiveness is

Robotic arm control through mimicking of miniature robotic arm
2017 4th International Conference on Advanced Computing and Communication Systems (ICACCS), 2017In the recent technology advancements, employing robots for handling precise operations were seen in abundance like industrial, medical and rescue operations etc. Introducing human interaction with the robotic arm in the real-time scenario opens new doors in innovations and applications of the robotic arms.

Simulation of a cartesian robot arm
Proceedings. 1984 IEEE International Conference on Robotics and Automation, 2005This paper describes a program for the simulation of the control logic and system dynamics of a robot arm having three Cartesian axes of motion plus two rotational axes of the wrist. The program was written in the C language and includes a fourth-order Runge-Kutta algorithm for the integration of the nonlinear differential equations for the individual ...

Fluoroscopic C-arms are common devices for acquiring images during surgery. Manual positioning is time consuming and requires considerable experience. Trained users must often take several images to find the best viewing direction. If a second image must be taken from the same position, e.g.

When two robot arms execute coordinated motions in assembly, collision between the two end-effectors cannot be avoided. The collision effects on the robot motions are studied in this paper. Firstly, the joint velocities of the two coordinating arms have abrubt changes at the instant of collision. Secondly, an impulsive force exerted on the end-effector
