8. Creation of Override Mechanism
Designed by team led by Constantino Fiuza in Fall 2014
Design addresses the following requirements
Easy assembly
Allows safety driver to disable main steering safely
Able to return steering
Reword
Design has gradually evolved over time
Keller
The design for the override mechanism was created by Constantino Fiuza in the Fall 2014 semester. The way he was able to come up with this design was by simply looking at the requirements: it must be easily assembled, it must allow the safety driver to safely disable the main driver’s steering, and it must be able to return steering control to main driver.

18. Steering Column Mid-Semester Design Review - Designed new part in CAD
Current Status - 3D printed prototypes, researched materials and vendors/pricing, purchased materials, manufactured new part
Next Semester - Install and test new part
Combine with next slide
Rephrase

19. Key Area of Success - Material Research
Lifespan (durability & reliability)
Stress Corrosion
Fretting Corrosion
Galvanic Corrosion
Price
Manufacturing Techniques
Subsequent purchase of affordable stock material and completed manufacturing

20. EPICS CAR Brake Testing
Safety Protocol:
Preventative Measures
Site Safety
Driver Apparel
Safety Equipment and Response Team
Response Procedures
Ground Response to Crash or Spinal Injury
Driver Response to Brake Failure
Driver Response to Loss of Control
Driver Response to Roll Over
3. Side Note: If anything unfamiliar begins to occur, stop testing and access the situation and judge whether testing should be continued or not!
Explain basic procedure steps

21. EPICS CAR Brake Testing
Static Force Test:
Materials:
Force Gauge
Rope/webbing/Cord
5 gallon bucket (optional for different friction)
Camera (optional for step 5)
Car
Procedure:
Tests brakes by remaining stationary
Record whether car slips, begins to roll, or remains stable
Will show whether the car’s brakes are stronger than friction of surface
Explain basic procedure steps

22. EPICS CAR Brake Testing
Towed to Speed Testing:
Materials:
Timing Device
Measuring Tape/Wheel
Chalk
Speed Measuring Device
Car
Procedure:
The car’s brakes will be tested on a flat surface at different speeds
Start by pushing (use vehicle when necessary)
Perform test in intervals of speed and force
Explain basic procedure steps

23. EPICS CAR Brake Testing
Hill Speed Testing:
Materials:
Water (bucket or hose)
Survey Equipment/Barometer
Measuring Tape/Wheel
Chalk
Speed Measuring Device
Car
Procedure:
Tests the brakes at increasing speed intervals
Accomplishes same as towed to speed except using hill for speed
Car starts at certain locations on the hill (30 ft intervals)
