  2. Meet the Team [ME, CE] Jon Teske - ME Colin Gordon - CE MajedAlateeq - CE Jaeheung Park - ME

  3. Scooter Project - Introduction Last Mile Transportation • Utilize Ultra-capacitor Technology • Long-Lasting • Highly Efficient • Powerful Storage/Release Capabilities Brake-Energy Regeneration

  4. Project Background TEAM JET-TREAD • Jet-Tread Project Goals: • Design and build a lightweight electric kick scooter • The vehicle will incorporate regenerative braking and ultra-capacitors to provide power assisted riding without charging batteries

  5. Continuation Project Goals • ScooterizerProject Goals: • Produce a prototype scooter that is lightweight and foldable, easy to use, and provides an electronic boost for uphill travel. • Provide future design teams with a database of knowledge, so that they can benefit from our project learning and experience. Improve On and Learn From Jet-Tread Design 5

  6. Project Discovery Identify Areas for Improvement • Electrical and Control System • Control system needed improvements • Electrical system needed circuit isolation • Human-Machine Interface • Drive to Regenerative mode switch needed user-friendly enhancement • Cleaner throttle • Add regenerative brake control • Usability of the Scooter • Needed means of detaching motor from wheel (free-wheel mode)

  7. Scooterizers Solution • Electrical and Control System • Improve circuit protection elements • New control system • Human-Machine Interface • New throttle, brake and Drive-Regen mode switch • Usability of the Scooter • Add a clutch for free-wheel mode

  8. Improvements – Electrical and Control System

  9. Improvements – Electrical and Control System • Modular Control System • 5 boards = 4 Subsystems, with Master controller Atmel ATMega48 Microcontrollers • Circuit Safety/Isolation Mechanisms • KISS principle: SPDT automotive relays

  10. Improvements – Human-Machine Interface • Twist Throttle • Easy to interface with control system’s ADC hardware • Ultra-capacitor Bank Mode Switch • Regenerative mode in low voltage (2.7Vdc) • Drive mode in high voltage (13.5Vdc) • KISS!

  11. Improvements – Scooter Usability • Electromagnetic Clutch for the Scooter • Allows the Scooter to be used in freewheel mode • Small, lightweight and easy to use with scooter control system

  12. Challenges Overcome • Sheer Amount of Documentation • Difficult to find needed information • Reverse-Engineering the ESC Circuit • Lack of specific documentation required support • Broken Components • ESC from previous project had been “cooked” • Lack of EE Knowledge • Graduate student help needed • Realizing the Scope of the Project • Important to agree on this as a team TIME.

  13. What we Learned Team Balance is Important Good Time Management is Essential State Realistic Expectations Interdisciplinary Learning [ME, CE, EE] Real-World Client Communications Lots of Individual Learning Engineers Wear LOTS of Hats!

  14. Future Project Directions • Open-Source Electronic Speed Controller [CE, EE] • Make it reusable, configurable for other Senior Design projects • Design and Build a Hub Motor [CE, EE, ME] • Great idea but hard to find a commercial one • Drive Mode and Regenerative Mode Power Supplies [EE] • Radically increase efficiency of the system
