Bridging the Gap FROM STRATEGIC ANALYSIS TO DETAILED DESIGN DANNY BLAU ANDYMARK, INC 1

Background Started in FLL in 2002 – City Sights Started in FRC in 2004 – FIRST Frenzy Drove for alumni team in ‘07 and ’08 Mentored various teams in Milwaukee and Minneapolis Lead mentor for 3184 in 2013 – Ultimate Assent Rocket Scientist (day job) Lead technical mentor for 1529 starting 2014 – Ariel Assist Design Engineer (day job) for AndyMark, Inc. starting in 2013 Years in FIRST: 13 / Age: 25 = 52% ANDYMARK, INC 2

From A to B Strategic Analysis A break down of the game How are points scored How are they de-scored (if applicable) What’s the Meta-Game What is the ranking system End Goal: What does my robot/driver/HP team need to do? Ranked Priority list Single sentence description Detailed Design End Goal: ANDYMARK, INC 3 FRC 1529, FRC 3618, FRC 1425

Design Space Combining Tops-Down and Bottoms-Up Intent Create visual representation on the space in the robot that’s left your you design within Add in Sub Spaces for other elements of the robot that you have yet to design Sub spaces are based on what style of mechanism your team is using*** ANDYMARK, INC 4 FRC 3184

How to prepare your Design Space Tops Down Large scale parameters that can’t be broken FORM THE MANUAL Sub spacers Bottom Up Detailed parts that already exist Kit Chassis Gearboxes Motors Electrical Components Other COTS Parts from past years Etc. ANDYMARK, INC 5 FRC 3184

***Quick Aside – Mechanism Selection Things that matter Reliability Consistency Maintainability Can it be fixed or swapped within 5 minutes? Cycle rate/throughput potential Driver Margin of Error Integration with other robot systems Things that don’t matter Is it Type A or Type B? Strait shooter Vs Curved shooter 1 wheel vs multi wheel shooters 1 vs. 2 sided conveyers Pneumatic Vs Motorized Vs Spring Tension Catapults ANDYMARK, INC 6 Start 1 st Thing 2 nd Thing 3 rd Thing Start Thing A 2 nd Thing A Thing BThing C 2 nd Thing C 3 rd Thing C

Sub Spaces These are shapes are to help design your specific mechanisms You must first know what type of mechanism you’re building Prototyping Mechanism Selection slide These shapes are totally defined by the game pieces and field Read the Manual! Understand the Manual!!! ANDYMARK, INC 7 FRC 1529

Combining Sub-Spaces Using separate design spaces for each component that moves independently Major assemblies should move as they will in real life Use this stage to dummy check interferences Interactions Cyclical references What elements will ‘snow ball’ in your favor What elements ‘snow ball’ against you Systems Engineering*** ANDYMARK, INC 8 FRC 1529

***Quick Aside – Systems Engineering Mercedes 2014 F1 Engine Total departure from convention Totally epic performance 18 of 19 pole positions 16 of 19 race wins 701 points (2 nd place team 405) 2 F1 world titles ANDYMARK, INC 9 This cutaway drawing is courtesy of Paolo D'Alessio.

Populating Your Sub-Space Start to add in purchased parts Add in known Custom Parts Develop new parts from known points and constraints Start with low detail proto-parts Only add time consuming details when Production ready Fasteners Lightning cutouts ANDYMARK, INC 10 FRC 1529

Take a Moment – have a CDR Gather the team and outside perspective and scrutinize the design Leave no stone un-turned Analyze all spacers and low detail parts If CDR is successful: 1.Complete detailed design can be finished 2.known parts can be release for fab while dependent parts are finished 3.All parts designed and released for fab 4.BoM Finalized 5.Remaining COTS ordered ANDYMARK, INC 11
