WHAT IS THE DESIGN TEAM?
What revolves around Design team decisions

DESIGN TEAM REQUIREMENTS
AFTER SPECIFIC SKILL SETS THIS IS THE MOST
IMPORTANT TRAIT. IT INCLUDES RECOGNIZING THE
TEAM GOALS OVER INDIVIDUAL ONES. THIS PART OF
BEING ON THE TEAM WILL BE HELD UP TO THE HIGHEST
REGARD
EXHIBITED TIME AND EFFORT TO ROBOT DESIGN AND
MAINTENANCE
POSSESS A SPECIFIC SKILL NECESSARY TO BUILD
PROCESS
HAS SPECIFIC ABILITY TO CONVEY BUILDING
PROCESS IDEAS THROUGH A VARIETY OF VENUES

THE DESIGN PROCESS

• Iterative design
• The idea that design should be done in
  repeated cycles where, in each cycle, the design
  is elaborated, refined, and tested, and the
  results of testing at each cycle feed into the
  design focus of the next cycle.
• At kickoff, identify a vision of what our
  robot would look like on the Einstein Field in
  Atlanta, then
• Prioritize strategies, combine similar
  strategies and then start design cycles. The
  following four slides are four different ways to
  cycle information from one level of competency to
  another.from good physics, to good testing, to
  good integration and testing

Design Process

• 1. Design-prototype-test cycle
• A design process methodology of driving
  changes in design through successive
  instantiations of the design that are evaluated
  through some type of user testing, user feedback,
  or inspection technique.
• design - generate ideas, analyze, and create
  solutions
• prototype - envision the design by creating an
  instantiation of it, whether through a paper
  prototype or a functional system
• test - evaluate the prototype. uncover bugs.
  uncover usability problems.
• go back to step 1 - using the evaluation,
  redesign and improve the design

9
Design Process

• Pervasive usability
• A principle of design that advocates the
  application of usability methods in every stage
  of the design process. Some of the primary stages
  of design, and some example usability techniques,
  are
• Information gathering
• Task analysis, cognitive modeling
• Design generation mockups, information
  architecture, prototyping, brainstorming
• Design evaluation user testing, usability
  inspection, walkthroughs
• Production iterative design
• Validation field testing, competitive user
  testing, stress testing

10
Design Process

• Prototyping
• The development of incomplete
  representations of a target system for testing
  purposes and as a way of understanding the
  difficulties of development and the scale of the
  problem.
• Prototyping is an essential element of an
  iterative design approach, where designs are
  created, evaluated, and refined until the desired
  performance or usability is achieved. Prototypes
  can range from extremely simple sketches
  (low-fidelity prototypes) to full systems that
  contain nearly all the functionality of the final
  system (high-fidelity prototypes).

11
Design Process

• Spiral Model
• A classic approach to project management.
  The spiral model is an iterative approach that
  begins by developing basic requirements, building
  small simple prototypes, evaluating those
  prototypes, and then expanding into refined
  requirements and consecutively larger prototypes,
  until a complete deliverable product is created.
  Prior to the final product, each prototype is
  deliberately built with the expectation that it
  will be thrown away.

How to start our design cycles

• 1. After down load of game, and rules and
  regulations are all common knowledge. We, as a
  design team go from a Vision of a Championship
  robot to a common understanding of the strategy
  robot we want.
• 2. Once a strategic robot is decided,
  IDENTIFY FOUR MOVEMENTS LERT
• LINEAL-ANY MOVEMENT ALONG A STRAIGHT LINE WITH
  THE EXCEPTION OF ANY REACHING OUTSIDE
  FOOTPRINT.
• EXTENSIONAL- THE REACH OF THE ROBOT
• ROTATIONAL-IF THE MOVEMENT INCREASES THE WORK
  ENVELOPE AND CAUSES THE END OF THE ARM TO FORM AN
  ARC IT IS ROTATIONAL MOVEMENT.
• TWISTING-A TURN ABOUT THE CENTER POINT. IF THE
  MOVEMENT DOES NOT CREATE A LARGER WORK ENVELOPE
  IT IS A TWIST. PITCH AND YAW ARE ROTATIONAL, BUT
  THE ROLL MOVEMENT IS AN EXAMPLE OF A TWISTING
  MOVEMENT
• THEN BASED ON YOUR STRATEGIC WORK
  ENVELOPE, DECIDE ON THE NUMBER OF DEGREES OF
  FREEDOM YOU NEED. TRY TO MINIMIZE SUB-MOVEMENTS
  IN THE MANIPULATION OF YOUR END-EFFECTOR.NEXT,
  IS MATCHING UP SUB-GROUP DESIGNS TO DEGREES OF
  FREEDOM NEEDS

Design Process

• Identify all phases of game scoring matrix
• Identify all strategies possible in game
• Prioritize strategies from a championship
  perspective
• Combine, if possible, common strategies
• Decide on strategy robot
• IDENTIFY DOFs
• MODEL, PROTOTYPE FROM SMALL WORK ENVELOPES TO
  LARGER ROBOTICS SYTEMS
• INTEGRATE ALL SYSTEMS LOGICALLY
• .Assume all strategies can be built!!!

MORT DESIGN TEAM TIME LINE OF ENGAGEMENT

• January 5th kickoff
• January 6th initial meeting after vision robot
• January 7th-? Strategy robot large and small
  group meetings
• January ?-Democratic vote on final strategies
• January ?-? Modeling, prototyping, integration
• Nightly meetings on systems integration

MORT Systems Integration
All sub-groups must be constantly met with during
6-week build season to make sure all design
cycles are meshed towards deliverables.
Design team must make decisions to make sure
that each sub-group understands how they
interface with other sub-groups during build
season.
