A new robot toolbox for dynamics simulation based on MATLAB Graphical User Interface (GUI) is developed for educational purposes. It is built on the previous version named as ROBOLAB performing only the kinematics analysis of robot manipulators. The toolbox presented in this paper provides interactive real-time simulation and visualization of the industrial robot manipulator's dynamics based on Langrange-Euler and Newton-Euler formulations. Since most of the industrial robot manipulators are produced with six degrees of freedom (DOE) such as the PUMA 560, the Fanuc ArcMate 1 20iB and Stanford Arm, the library of the toolbox includes sixteen fundamental 6-DOF robot manipulators with Euler wrist. The software can be used to interactively perform robotics analysis and off-line programming of robot dynamics such as forward and inverse dynamics as well as to interactively teach and simulate the basic principles of robot dynamics in a very realistic way. In order to demonstrate the user-friendly features of the toolbox much better, simulation of the NS robot manipulator (Stanford Arm) is provided as an example. (C) 2009 Wiley Periodicals. Inc.

The application of the Automatic Drilling/Riveting (ADR) System realizes automation of the wing panel riveting assembly. However, a major obstacle to the ADR of wing assembly in the past has been an inability to rapidly reduce locating deviation that usually existed between the upper- riveting head and actual locating points. This case largely influences actual production. To increasing locating accuracy and processing efficiency, a new method for errors analysis and rapid correction was proposed. Firstly, by analyzing the process flow of ADR, the resources and causes of errors were obtained from the analyzed results. Secondly, defined locating points in 3D model, then offset the points to modify the deviation between locating points in 3D numerical modeling and actual locating points in located and clamped wing panels. The modified data is from site measuring. Thirdly, software CATIA secondary development software CAA (Component Application Architecture) was applied to develop Rapid Error Correction Module in off-line programming. The locating points were obtained by the Agent technology and the batch definition was implemented on the visual interactive definition platform. The locating points were corrected by the AUTOMATION interface and the offset based on the template document was completed, the final locating points were determined by the linear programming. Finally, implementation on wing panel riveting assembly was introduced, and the results demonstrated the functionality of the method.

In this paper, to improve the efficiency of welding and user convenience in the shipbuilding industry, a PC-based off-line programming (OLP) technique and the development of a robot transfer unit are presented. The developed OLP system is capable of not only robot motion simulations but also automatic generations of a series of robot programs. The strength of the developed OLP system lies in its flexibility in handling the changes of the welding robot's target objects. Moreover, for a precise transfer of the robot to a desired location, an auxiliary mobile platform named a robot-origin-transfer-unit (ROTU) was developed. To enhance the cornering capability of the platform in a narrow area, the developed ROTU is equipped with 2 steering wheels and 1 driving wheel. Both the OLP and the ROTU were field-tested and their performances were proven successful.

In this paper, a PC-based off-line programming (OLP) method using the virtual reality modeling language is proposed. The developed OLP system consists of simulation programs, a block-arrangement algorithm, an optimal traveling-path generation algorithm, an automatic robot program generator and the TRIBON CAD interface. The strength of the developed PC-based OLP system lies in its flexibility in handling the changes in the robot's target objects. The operator can generate robot programs very easily and quickly. Possible applications of the developed OLP can be extended to port automation, container loading/unloading processes as well as painting and grinding processes in the shipbuilding industry.

Robotic manufacturing systems are widely used in industry. These systems are composed of many automated machines, industry robots and sensors. However since these systems are composed of many Robots, which share their workspace, they are very complex to be coordinated. In order to complete the production task accurately, optimized, without any collision and without interruption,of production flow these systems must to be simulated. Nowadays manufacturing processes are supported commonly from the simulation models. This new technology of modelling guarantees a high accuracy finished tasks, optimized flow of production and coordination of all components and Robots too. This paper describes briefly the use of the software tools to simulate and optimize the production process on the flexible manufacturing cell for the various parts. The software used on this research was RobotStudio.

A new experimental tool calibration method is proposed to upgrade the accuracy of robotic conformance grinding system. The horizontal axis deflexion error of grinding tool achieved by this new method is below 0.05 degree, and the calibration method turns to be easy and practical. Based on the conclusion of the universal calibration methods for the static contact wheel, the tool of grinding, the authors forward the conception of the new method and prove its validity theoretically, then introduce the robotic system components and set up the experiment system, and make the test grinding experiments to magnify the deflexion. After the process of complete grinding between the contact wheel and the sample piece, the experimental data are recorded and analyzed. After obtaining the grinding tool's current deflexion from the ideal pose, the authors compensate it to the programmed tool pose, and grind the sample piece using the robotic grinding system to verify the accuracy and feasibility of this method. Its conception comes from that if the tool frame has a deflexion from the programmed pose, and this deflexion is trigonometrically related to the depth difference in the grinded sample piece.
