  1. CSE Design Lab – Milestone 2 • James Hopkins • Dave Festa • Dennis O’Flaherty • Karl Schwirz

  2. Milestone 2 Overview • Project review • MSRS • Robotics application • Service abstraction • Lego NXT • Scope of work • Project definition • Budget • Timeline • Present robot

  3. Project Review • Implement Microsoft Robotics Studio • Development platform for robotics community • Users • Hardware • Scenarios • Addresses challenges for developing robot applications • Concurrency and distribution • Scalability • Code reuse and reliability

  4. What is a Robotics Application? • An application is a composition of loosely-coupled components concurrently executing • Orchestration of sensors/actuators • User interface • Controlled/Autonomous behavior • A service is the unit of orchestration

  5. Service Abstraction • Services can represent any computation • Hardware: Sensors, actuators,… • Software: UI, Storage,… • Aggregation: Sensor fusion,… • Authoring tools • Simulation visualization tool • High resolution 3D rendering • Visual and physical views • Enables prototyping and debugging

  6. Highly Diverse Market… Lego NXT

  7. Lego NXT • Why Lego NXT? • Not electrical engineers • Not mechanical engineers • Demonstrated technology • Microcontroller • Sensors • Servos • Budget • Scalable and customizable

  8. Scope of Work • Project definition • Develop software platform to coordinate robot activity • Manual control with UI • Autonomous operation • Integrate sensor data (distance to nearest object) into UI • Provide visual representation • Support manual control interface • Enhance autonomous operation • *Implement 2-robot control application • Build robot using Lego NXT • Robust • 360 degree movement • Touch sensor for obstacle avoidance • Ultrasonic sensor for movement control

  9. Budget • 2 Lego NXT Kits: $500 • 2 Bluetooth's: $64 • 12 AA batteries: $10 • MSRS: $0

  10. Timeline

  11. Robot Presentation The Ultrasonic Sensor measures distance. It is able to measure distances from 0 to 255 centimeters with a precision of +/- 3 cm. Each motor has a built-in Rotation Sensor which measures motor rotations in degrees or full rotations [accuracy of +/- one degree]. The Touch Sensor gives your robot a sense of touch. The Touch Sensor detects when it is being pressed by something and when it is released again.
