  1. Preliminary Design Review MACH 1/7 Daniel Bressan David Tran Robbie Banks Amit Kapoor

  2. Purpose To build and design a fully functional, completely electric remote controlled car that will be able to reach speeds greater than a 100 miles per hour. David Tran

  3. Objectives • Have a control system that ensures stability at high speeds. • Develop a power system to power all necessary components within the car. • To design a high performance chassis and shell. • Use an onboard microcontroller to integrate all the various systems within the car. • Integrate a RF system for communication between a laptop and the car. David Tran

  4. The Plan David Tran

  5. Input • We will build a GUI interface to control the car. • Mouse • Keyboard • GUI will control speed and steering. • Debugging • Force Sensor • Optical Encoders • Battery Amit Kapoor

  6. RF System • Testing/Backup • 2 Channel Pre-Built RF Radio • 27 MHz • Testing/End User • Xtend-PKG • 900 MHz • Via Serial Port • Size • Will go both ways • Display speed in GUI • Debugging Daniel Bressan

  7. Micro Controller • MSP430-F2616 • Cheap • Same Processor as Power Lab • Support • Control • Speed • Stability • Power • RF • Specs • JTAG • RISC • Low Power David Tran

  8. Power System • LiPo 3 cell Batteries • Quick Constant Power • High Amps • Supply Power to • Motors • CPU • Speed Encoders • Force Sensors • Gyroscope • RF Robbie Banks

  9. Motors • Three Phase Brushless Motors • Constant power supplied • Good torque at high speeds • Low Turn Motor for higher RPM • Programmable for high efficiency at low and high speeds • Need upwards of 10-15 thousand RPM • Possibly 2 for 4WD Robbie Banks

  10. Powering Motors • The motors take three inputs, each is a sin wave 120 degrees out of phase with each other. Robbie Banks

  11. Power Control • A three phase output is created by turning on and off the six transistors at a specific frequency and time. • We will need to regulate the frequency so that we get maximum acceleration Robbie Banks

  12. Control • Speed Encoders • Relay speed to MCU for stability • Relay speed back to user • Sensors • Force Sensor • Anti-Lift • Inclinometer • Steering • Pre-Built • Stepper Motor • Gyroscope David Tran

  13. Mechanical • Create own starter kit for testing • Kitchen cutting board for chassis • Motors • Wheels • Axels/Gears • After electrical complete start: • Chassis (Aluminum) • Shell (Carbon Fiber) Robbie Banks

  14. Division of Labor Amit Kapoor

  15. Schedule Amit Kapoor

  16. Budget Amit Kapoor

  17. Feasibility • From our predictions this project is feasible! • Stay within Budget and Schedule • Finish Line RC • Budget • 10% off • Accessibility to parts • Good allocation of tasks • Hard Work • Team Work • 90% of Project Management is COMMUNICATION Daniel Bressan

  18. Risks and Recovery Risk Recovery • Schedule • Big Project • Budget • Money for all needed parts • Knowledge • Learning software/components • Motors • Speed and cost • Weight • Breaking Car in Testing • Schedule • Replace pre-build products as needed to stay on schedule/testing • Budget • UROP • Out of pocket • 10% off • Knowledge • Ask questions • Google • Data Sheets • Finish Line RC • Motors • Be specific • Talk to experts • Breaking Car in Testing • Be very very carful • Sensors • Kitchen cutting board Daniel Bressan
