Parallel Development of Autonomous Robots with a Focus on Modularity

This project focused on the parallel development of autonomous robots with a modular chassis design. Teams competed in stages testing electrical components, detecting electromagnetic fields, and entering specific codes before a final task of aiming and firing darts. Communication between robots was facilitated using SPI while also incorporating solenoids and Schrader valves for compressed air. The tower housed hidden electronics and featured adjustable pitch and yaw. This entry showcases an innovative approach to robotics development at the IEEE Region 3 SoutheastCon Hardware Competition 2017.

  1. Parallel Development of Autonomous Robots with a Focus on Modularity Brittany Hand, Jeffery Hay, Ross Heninger, Andrew Mandeville, Matthew McDonough, Jordan Miller, Fredi Mino, Fiona Popp, Corey Pullium

  2. IEEE Region 3 SoutheastCon Hardware Competition 2017

  3. IEEE Region 3 SoutheastCon Hardware Competition 2017 Final Stage Stage 1 Stage 2 Stage 3

  4. Stage 1: Stage 2: Stage 3: Final Stage: Rules

  5. Multiple Chassis

  6. Modular Chassis

  7. Modular Chassis

  8. Stage 1: Determining Electrical Components Total height of inner black box is 10" middle node (ground) is 7" high • Ground in the middle • Resistor Inductor Capacitor Diode Wire • Discover which pad has what

  9. Approach Making Contact Sensing Components Stage 1: Determining Electrical Components

  10. Stage 2: Detecting Electromagnetic Field • Strike the vibration sensor • Then hit the vibration sensor every time the electromagnet is active. (4 more strikes) • Must detect for 30 seconds Tip: 10" high Base: 7" high Electromagnet: 1" high

  11. Stage 2: Detecting Electromagnetic Field

  12. Stage 3: Entering Code • Use code from Stage 1 Example: 3,5,1,2,4 • 3 CW rotations 5 CCW rotations 1 CW rotation 2 CCW rotations 4 CW rotations

  13. Stage 3: Entering Code

  14. Final Stage: Aiming Darts 6”x6” • Put 3 nerf darts through the hole • After final dart...Match ends • Shoot vs. Climb & drop 2” step 1” step 0.5” step

  15. Final Stage: Firing the Darts Solenoids values for sudden decompression Compressed air (2 bar) inside flexible tubing Schrader valves for pump connection

  16. Final Stage: Aiming Adjustable pitch Adjustable yaw Tower with hidden electronics

  17. One start button One stop button Transmission of code from Stage 1 to Stage 3 Waiting to fire the last dart Communication

  18. Serial Peripheral Interface (SPI) The tower (master) interrupts the other robots (slaves). Passive Ex: Master >> “s”(status) (done)“d” << slave Communication

  19. Serial Peripheral Interface (SPI) Active Ex: Master >> “b”(begin) (garbage)“#” << slave Communication

  20. Start button Polls for status of 3 robots When gets “done” requests code Transmits code to dial When all “done”, fires last dart Communication

  21. 5th Place Results & Conclusion
