  1. AUTOMOTO Group 16 Gregory Berkeley Levi Lentz

  2. Acomplishments • 1. Found Center of Gravity • 7 inches from the vertical • 2. Developed Parts List and Spec Sheets • Motors, Drivers, Controllers, Batteries • 3. One microprocessor was missing a DC adapter from a 9V • Soldered adapter to 9V leads giving the unit power • 4. Set up simple Arduino commands

  3. Center Of Gravity

  4. Flaw with Previous Design • Only were using a proportional control with a gain of 1 for control steering • No Integral or Derivative Control • Too slow of a time response to achieve stability • Evidence found in videos from the previous team • Our Remedy • Reconfigure the control system to incorporate PID controls

  5. Microprocessing • Currently using two Arduinos • One to drive DC Motor • Another to control stepper motor steering • Programming is very similar to C • Task 1: Get sensor and Arduino to talk to each other and read data (ArduFlight) • Task 2: Incorporate Stepper Motor to test time response

  6. Pulse Width Modulation

  7. Gull-Wing Training Wheels • Retractable “Training Wheels” • Solve problem of starting the vehicle • Will retract in a Gull-Wing manner • Add to the rotational inertia of the bike • Linear actuation via 4 bar link • Or with simple rotation

  8. Future Work • Get electronics to work • Independent high- and low-power systems • Eventual integration of both systems • Contact previous team for full wiring schematic • Review previous code • Design “Training Wheels” • Cad design • Rotation or 4-bar link • Integrate control into speed-sensing Arduino
