1 Technical Robustness and Quality

2 Rock Solid Robot Page Title 1-4 Robustness In Concept And Fabrication 5 Creative Concepts For Tomorrow s Technology 6-8 Rock Solid Controls 9-10 Effectively Achieves Game Challenge

3 ROBUSTNESS IN CONCEPT AND FABRICATION Design Concepts Moon Rock Harvesting Mechanism Simple Carryover concept which has been proven to work well (2006 and 2008 RUSH robot) Chassis Chain Tensioner Packaged internally in the chassis frame rails Set-it and forget it Proven to work Modular Design Concepts 4 robot sub teams created systems All sub teams created sub system in Inventor All sub teams bench built their system RUSH for the Future / 1

4 ROBUSTNESS IN CONCEPT AND FABRICATION Quality Aspects Implement safety in all areas of build Robust organization Effective Communication Exemplifies Gracious Professionalism Graphics and material colors match team uniform Robust Design Concepts and Fabrication Designed for easy and simple service Robust Fabrication Created Welding Fixture Reduced welding time Minimized build variances Utilized Aluminum Tube and Plate Durable Strong Cost effective Light weight 2 / Technical Robustness and Quality

5 ROBUSTNESS IN CONCEPT AND FABRICATION Design for Service Open Design Concept Increases serviceability of internal components Control components are always in clear view Lightened polycarbonate controls mount - Lightened poly-carb mount - Space saving design Pre-Lightened Materials Prior to Assembly/Welding Reduces overall robot weight by 10% Robust Organization Business Oriented 4 technical sub-teams Weekly design reviews Integrates business software Design Process Cost and weight targets assigned in week one Prototypes constructed to validate design and updated as design developed Utilized lean manufacturing techniques RUSH for the Future / 3

6 ROBUSTNESS IN CONCEPT AND FABRICATION Safety Pit Competition Robot Checklist Wheel guards on moon rock launcher Safety glasses required in the shop Tethered kill switch for practice session Required machining/tools/shop training 4 / Technical Robustness and Quality

7 CREATIVE CONCEPTS FOR TOMORROW S TECHNOLOGY Ball Management System Ball Containment Unit Stores space rocks in single file - Prevents jamming - Allows empty cell management Elevator Lifts rocks up to shooter - Keeps rocks in straight line - Minimizes jamming - Adjusts for broken or misshapen rocks - Can detect jamming and auto reverse 5 start lead screw Fast linear motion Smooth actuation Auto jam detection Encoder feedback Auto-calibration via light sensor Linear bearing Two sensors to eliminate false detection Can detect rising vs. falling edge - Ball in - Ball out Closed loop feedback Spur gear drive Adjustable backlash RUSH for the Future / 5

8 ROCK SOLID CONTROLS Main RUSH Control VI Waypoint Navigation Camera Tracking 6 / Technical Robustness and Quality Traction Control

9 ROCK SOLID CONTROLS Waypoint Navigation X-Y Coordinate Overlay Graphical input 4 encoders, 1 gyro Collision recovery RUSH for the Future / 7

10 ROCK SOLID CONTROLS Traction Control Reference wheel encoders - (2) Compared to drive wheel encoders - (2) To adjust speed and acceleration - Collision detection and compensation Measures rate of acceleration Emulates real-world automotive style traction control Camera Tracking Tracks up to 5 trailers simultaneously - Uses web cam - Color detection to identify opposition Uses pixel analysis to determine distance Closed-loop wheel speed - Encoders made from light sensors - Shifting on lower wheel Visual LED target acquisition indicator 8 / Technical Robustness and Quality

11 EFFECTIVELY ACHIEVES GAME CHALLENGE Versatile Loading Large Basket Enables Robot to be Loaded from Anywhere Helps payload specialists load easily Allows other robots effortless loading Simple Chain Driven Roller Picks up moon rocks from the crater Simple Ball Organization Easily Sorted Separates empty and super cells Prevents Jamming Consistent Delivery to Shooter Factory-Like Process RUSH for the Future / 9

12 EFFECTIVELY ACHIEVES GAME CHALLENGE 6-Wheel Drive Simple Universal chassis Effective Maneuvering Traction Control Compares speed of reference wheels to driven wheels Prevents sliding Multi-Faceted Shooter Uses Camera to Track Trailers Distinguishes between targets Chooses closest opponent s trailer Has a 1-12 Foot Range Uses servos to change gears on transmissions On a Turret Rotates 360 degrees 10 / Technical Robustness and Quality
