  1. Design of an Integrated Robot Simulator for Learning Applications Brendon Wilson April 15th, 1999

  2. Outline • Introduction • Design Tools and Techniques • Overview of Simulation Architecture • Feature Set • Demonstration • The Future of REMOTE • Summary • Questions

  3. Introduction • Scope of REMOTE project • Remote experimentation for tele-learning • Prime audience: ENSC 489 students • Target experiment: Scorbot ER-III • Scope of Thesis • Simulation platform for Scorbot • Flexible and maintainable architecture for future additions

  4. Design Tools and Techniques • Design Patterns • Provide abstractions to maintain flexibility • “Ready-made” solutions • Creational, structural, or behavioral • Unified Modeling Language • Documentation of design • Java • Implementation language • Platform independent

  5. Overview of Simulation Architecture

  6. Solution to Typical Problem • File Parsers for Simulation Engine • Responsible for parsing 3D models, robot configuration, simulation files • Should be replaceable without changing core application • Program to interface not implementation • Externally configurable

  7. UML for Strategy Design Pattern

  8. Sample Implementation Detail

  9. Feature Set • Re-configurable robot simulation • configure model using Denavit-Hartenberg parameters • replaceable inverse kinematics and interpolation modules • Replaceable Architecture Components • File Parsers: 3D Models, Simulation Language, Robot Configuration Language • Full Internationalization • Images, error messages, menus

  10. Demonstration

  11. The Future of REMOTE • Integration with REMOTE robot server • Integration on new Java3D Loaders • Simulation of multiple robots • Possibilities for manipulators • CAD/CAM machinery • General Inverse Kinematics Engine • Additions to the user interface • Other possible applications?

  12. Summary • Functional Scorbot simulator ready for integration with remote-experiment server • Most functions of simulation engine replaceable without alterations to existing code base • Simulation architecture simple enough that new features can be added without major overhaul of existing code

  13. Questions
