The Engineering Design Method outlines the systematic approach taken by the NMSU BEST Robot Design Team to create a competitive robot. This process involves defining the problem, performing background research, specifying requirements, brainstorming ideas, and choosing the best option. Teams create a design, build a prototype, and test their creations while making necessary redesigns. With limited time and materials, students learn essential engineering skills, teamwork, and problem-solving while aiming to win competitions. This guide encapsulates the journey of innovation in robotics design.

  1. The Engineering Design Method NMSU BEST Robot Design Team

  2. What is an Engineer? • Engineers are People who Solve Problems

  3. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  4. Define The Problem • What is your objective? • Win! • Create a robot that climbs a pole • Transport various objects From the 2012 Game Teaser

  5. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  6. Perform Background Research • What are the competition rules? • What do you have to do? • Google search • Has someone done anything similar? • Look for inspiration • This is a short-term project- save time for the other steps.

  7. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  8. Specify Requirements • Robot Size (24”x24”x24” <24 lbs) • Robot needs some way to move objects • Robot can’t interact with other teams • Limited materials to build robot • Six weeks • Etc.

  9. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brainstorm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  10. Brainstorm • Write down ideas • Stay on task • All ideas are ok at this point

  11. Choosing the Best Option • How do we chose the best idea? • Simple • Quick • Potential to work • Compatibility with resources • Something you understand

  12. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brainstorm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  13. Create a Design • Physics compatible • Motors can only do so much • Large motor rating: 23 in*lbs • Small motor rating: 9 in*lbs Length (inches) Robot Weight (lbs) Arm

  14. Create a Design • Where should I use what material? • Some parts should not be flexible • Use plywood • Some parts should be flexible • Use PVC

  15. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  16. Build a Prototype • Prototype is a working model of your robot • Time consuming part • Be problem solvers, don’t lose heart!

  17. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  18. Test and Redesign as Necessary • Rarely do you find a perfect product • May not have much time to do this • Fix the things that are most beneficial fist! • Fix others as you have times

  19. The Engineering Design Method • Define the Problem • Perform Background Research • Specify Requirements • Brain Storm – Choose the Best Option • Create a Design • Build a Prototype • Test and Redesign as Necessary

  20. Challenges to Come • Short time • Team dynamics • Difficult materials to work with • Be engineers, solve the problems!
