  1. REEB: Autonomous Drink RetrieverFinal Presentation Sarit Patel EEL 5666C – IMDL October 30, 2008

  2. Topics • Concept • Design • Hardware Solution • Software Solution • Demo • Conclusions and Future Work

  3. Concept • Design a robot that will retrieve drinks based on a user’s order. • Simple interface between user and robot.

  4. Design • Line tracking for navigation. • RFID ordering system. • Sonar to detect user within a certain range. • LCD and LEDs for feedback. • Servos for movement and actuation. • Bottle rack to hold different bottles. • Interrupt driven system.

  5. Hardware Solution • Line Tracker • 2 6-IR Sensor Line Tracking boards; Forward/Reverse • RFID Reader • ID-12 RFID Reader Module w/ antenna • Easy Serial interface w/ 1-4cm range • Sonar Sensor • Maxbotix LV-EZ1 module • Analog Output – 10mV/inch

  6. Hardware Solution • LCD • Simple 2 Row LCD for feedback • LED • RGB Led on top of robot used for different status indicators • Servos • Continuous Rotation Servos for movement • HS-475HB High Torque Servo for bottle arm

  7. Software Solution • Line tracking achieved with equation based system. • RFID tags sorted based on last two bytes of tag ID. • Interrupt driven system; Updates servo movements and system functions every 20ms.

  8. Demo

  9. Conclusions and Future Work • Robot performs main function correctly. • Custom environment needed to define behaviors in software. • Improve Line Tracking algorithm to smooth out jitters. • Add multiple RFID stations onto table top with wireless link to robot.
