Strategic Design and Systems Engineering in FIRST Robotics: Detroit-Mercy Kick-off Event
Explore the essentials of strategic design and systems engineering in the context of FIRST Robotics as highlighted during the Detroit-Mercy Kick-off event. Delve into the significance of strategic identification, design purpose, and systems engineering to optimize robot functionality and performance. Gain insights into traditional system engineering practices, match performance strategies, and game understanding for successful robot development. Prioritize qualities and functions to enhance robot capabilities and maximize scoring potential for competition.

Strategic Design and Systems Engineering in FIRST Robotics Detroit-Mercy Kick-off January 4, 2020
Who Am I? Peter Mueller Mentor for 1701 Robocubs and 1481 the Riveters Started mentoring for FIRST in 2008 Day job: Senior Design and Release Engineer Complete Seat @ Ford Graduated with a BSME from Detroit-Mercy in 1990
Strategic Design and Systems Engineering What is Strategic Design and why is it important Strategic Identification of aims and interests and the means of achieving them How do we get the highest functionality from our robot in this years game? Design Purpose, planning, or intention that exists behind an action, fact, or material object The team plans, CAD, drawings, and sketches we need to make our robot What is Systems Engineering Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles.
A FIRST Take on the S.E. V Match Performance Understand the Game What should our robot do Operator feedback How does our robot do it? System Integration/Testing Sub System Integration/Testing Sub System Design Component Build/Testing Component Design
Understand the game Every way to score positive and negative RP vs points climb or die Enable points Hatch Panels Bottlenecks/prevent scoring Rocket ship
What should our Robot be/do? What, not how. Two lists: Potential Qualities (fast, powerful, large, small, etc) & Potential Functions Brainstorming, not evaluating Prioritize Cost Benefit = most points, lowest difficulty Points/second Opportunity costs (practice and programming are valuable)
What should our Robot be/do? Golden Rules (Karthik) Build within your team s capability Three mechanisms that are 10/10 is better than 5 that are 6/10 Tradeoffs Use Priority Lists and Golden Rules to decide Rule of Thumb: Average teams do <4 full field cpm, top teams do 8 cpm Choosing to not do something is a win for the team, stick to it
How does our robot do it? Brainstorm Sub system concepts (from Prioritized functions) Benchmarking (Steal from the best, invent the rest) Prior Year match videos (https://www.thebluealliance.com/) Chief Delphi (https://www.chiefdelphi.com/) Listen to experienced mentors Keep it simple
How does our robot do it? Decision Matrix concepts vs evaluation criteria Prototype Frisbee Wheeled shooter (2013) Kinematic sketches Demo
Kinematic Sketches 2-D simplified representation Used to confirm geometric feasibility of a concept Example Power up pivoting arm concept
Sub-System Design Primary Purpose is to confirm system compatibility Find areas of conflict between systems Not detailed design. Use rough block shapes Simulate movement needed, conflicts often arise from moving through the same area at the same time. Include motors and gearboxes (use downloaded CAD)
Component Design Detailed CAD Add everything fasteners sensors belts bumpers Check Kinematics (motion) again Component drawings for build
Testing/Evaluation Shorter feedback loops = more time to fix problems Fail Faster Simulation Methods are best CAE, Kinematic sketches, prototypes, etc. Plan testing during the sub-system design phase using the Priority List from How does our robot play the game . Trying to answer the question, Does this (component/system) work the way we thought it would.
