  1. EGN:1935 ECE Adventures Team: Autonomous Robot: Lefty Team Members Daniel Crews Paul Stevenson

  2. Presentation Outline • Member bios • Design methodology • Problems and solutions • Team conclusions

  3. Bio of Daniel Crews • 1st semester Sophomore • Electrical Engineering major • Considering minor in Business. • This course has helped me decide that automated systems are fun to work with. • But quasi-real programming is…. awkward. • My goals at the University of Florida are to make it out alive, preferably with a degree that will take me to success.

  4. Bio of Paul Stevenson • 1stsemester Freshman • Chemical Engineering major on Pre-med track • I’d really like to get involved in Biomedical Engineering but it isn’t offered as an undergraduate major yet… • This course has helped me realize what a degree in Electrical Engineering allows you to do • I have also learned a lot about engineering in general • My goals at the university of Florida are to get an undergraduate degree and get accepted to the UF medical school

  5. Bio of Paul Stevenson (Cont.) • My goals at the university of Florida are to get an undergraduate degree and get accepted to the UF medical school • I also plan on getting a lot more involved in projects around campus • I hope to become a doctor with a specialization in some aspect of the field of medicine • Try and get as well-rounded of an education as possible.

  7. Design Methodology • Problem: navigate maze • Considered maze and determined what method (right wall following or left wall following…etc.) • Ultimately created a program that would use both walls to navigate the maze • To do this we used all of our infrared ports • Calibrating each one by trial and error • We used the sensors to avoid bumping into walls as well as follow them

  8. Design Methodology (Cont.) • We measured the average CDS cell reading on black and white paper to define a workable parameter for the code (so the robot would treat the black area as another wall • Initially our algorithm was designed to stop when a black area was detected, obviously when the scenario was altered, we had to rework that behavior

  9. Problems and solutions • Robot had severe leftwards drift due to unbalanced servos • - Required special consideration in code to compensate. • Dying batteries • -Required dealing with requisitions process with TA. • Excessive competition for on-track testing time • -Largely required making do with minimal testing, the crossing of fingers, and using the emergent behavior of the robot to provide error recovery. • Unprepared lab • -System setup, competitors had last lab’s working code to start with(we did not)…

  10. Team Conclusions • Its easy to program if you don’t have to program… • This simple application demonstrates the massive potential for automated machines • Working with real code is much easier than the lab’s “code”
