  1. Robotic Microphone Stand Team 19 Alex Lincoln Tyler Harrington Zach Newell

  2. Introduction • Motivation – Provide more efficient and accurate method for recording sound at Pogo Studios

  3. Objective • Create a wirelessly controlled robotic device capable of 10 movements • Program device to recall stored locations

  4. Design

  5. Power Supply • 11.1V 5Ah LiPo Battery • Wired into 5 motor drives (4 XY, 1 Z) • Delivers 3.2A when 4 motors running • Supplies 5V converter • Will deliver 3.2A for 1.5h or 1.6A for 3h • 5V buck converter • Servo (tilt) • Vcc for motor drives and encoders • 3.3V Regulator – Supplies WiFly Module

  6. Movements Design • Forward/Reverse • Right/Left • Up/Down • Tilt • Pan • Pittman 12VDC motor • 343 oz-in servo motor • Omnidirectional wheels Source: http://www.largescalerc.com/hs-805bbmegaservodualballbearing320ozin16sec22x12x24-1.aspx Source: http://www.vexrobotics.com/276-1902.html

  7. Movements Requirements • Vehicle shell • Weight limitations • Properly perform in all directions • Traverse in straight line • Spin on single axis for pan • Tilt 180 degrees Source: http://cosmoquest.org/forum/showthread.php/93909-Centrifuge-Forces-Equation

  8. Control

  9. Encoders

  10. iPad Application

  11. Microcontroller Logic Run Loop Opcode Present? YES Execute NO Update Location

  12. PCB Process • Proto-board Testing • PCB creation in Eagle • PCB #1 • PCB #2 • Extensive Testing

  13. Challenges • Multidirectional movement • Position recall • Fried motor drives • Safely powering down • Dead battery • Demo day

  14. Final Product

  15. Next Steps • Regulate battery voltage to 11 V • Build enclosure to eliminate shock hazards • Add sensors to prevent collision • Create a live video feed from device to Ipad app
