CAMS ROBOTICS TEAMNERD HERD : TEAM 687
BUILD
Chair l Thuan Doan
Build Overview
Competition VEX Robotics
Competition (VRC) FIRST Tech
Challenge (FTC) FIRST Robotics
Challenge (FRC)
What will buildies be doing?
Learning how to design, build, program, and test a competitive robot
CAD Machining Working with motors, pneumatics,
machines, electrical components, programming code
*NOTE* Experience is NOT necessary
FRC Build Sub Teams
Build sub-teams include Strategy Articulation Drive Electrical Programming
SYSTEMS ENGINEERING
Systems Engineers l Pat Capulong and Chani Martin
What do we do?
coordinate the work of the other leaders, each of whom is an expert on one part of the robot
coordinate the tasks involved in following the waterfall model
create and maintain documentation to ensure effective planning and execution
ensure that the team and the robot function efficiently and securely
STRATEGY
Director l Kevin Hsu
Robots
Robots come in all different shapes, sizes, speeds, weights, looks,
… and even genders Analyze the task you want to
accomplishChoose the design that will be best
for each game

Some things to consider: Drive Speed
Light and fast Slow and heavy
Articulation Arm 4-bar linkage Gearing?
Also, game mechanics: What to focus on Where to score Choose what’s best to
do based on situation
Alliances
Robotics is a team sport
Games are usually played with alliances of 2 or 3 robots
Be on the lookout for good teams, (but be nice to everyone)
Ending Message
Btw my name’s Kevin. I’ll be analyzing these games in excruciating detail to help you guys come up with the design best suited for each.
ARTICULATION
Leader l Vincent Kee
What is an articulation system?
Whatever manipulates the game pieces or lifts the entire robot
Everything on the bot besides drive base, electronics
Arms, claws, kickers, intake rollers, vacuum, elevators, baskets, hangers, etc.
What does articulation do?
Sketch, CAD, Prototype, and Machine Designs
Calculate Mechanical Advantage to find optimal gear ratios for motors
Work with Pneumatics and other cool stuff
If you don't know how to do any of this, DON’T WORRY, you will learn a LOT during the season!
DRIVE
Leader l Lauren Froschauer and Michelle Gonzalez
Who are we?
Drive Team is responsible for the drive system of the 2010-2011 FRC Robot
We work closely with all other sub-teams
What’s a drive system?
A drive system is the maneuverable platform on which the articulation is built
Many different types of drive systems are in existence
Types of Drive Systems
Four Wheel Drive Six Wheel Drive Tank Drive Mecanum Drive Omni Drive Crab Drive Ball Drive ;)
What do we do?
Learn about the different types of drive systems
Decide which type of DS (listed/not listed) is best suited for the 2010-2011 FRC Game
Design, CAD, and build the FRC DS Machine the drive system Use calculations to help design
Motor Design Calculator
ELECTRICAL
Leader l Isabel Lally
What does electrical do?
Basic robotic training Learn about and use electrical
components Learn and use electrical skills Design and create an electrical board
for the FRC robot Without us, the robot wouldn’t move
Electrical Components
Examples Power Distribution
Board Digital Sidecar Motor Controllers
Jaguar Victor
Electrical Skills
Examples Cutting and Stripping Wire Crimping Soldering
PROGRAMMINGTHE HEART AND SOUL OF ROBOTS
Leader l Mathew Francis-Landau
What do we do?
Subteam on FRC Debug a wide variety of problems Main platform is LabVIEW
Teach new members how to program, using the VEX platform Depending on a teams requirements, a
team can chose between easyC and robotC
VEX
Autonomous period is worth 10 points, twice as much as last year.
We want every team to have a least a few members that can make the full autonomous program for their robot.
FRC
For the FRC robot our main platform programming platform is LabVIEW
LabVIEW is designed for continuous data processing that is required by control system
Theories of Control
PID (proportional–integral–derivative) – close loop control system used to cancel out error Was used with the kicker on the last FRC
bot to consistently bring it back to the correct position
Low-pass filter – open loop system used to remove little imprecision from the drive, giving better control over the robot
Debugging
Debugging is the process of going from having a problem, to finding the cause, to designing the solution
When designing more complex systems, it is said that 10% is programming and 90% is debugging
Programmers usually do the most

MEDIA
Leader l Victoria Kim
Media Overview
The media team’s primary purpose is to promote the Nerd Herd image through design and social networking.
What do we design?
NerdHerd t-shirts CAMS Robotics’ website
Also managing our Facebook and Twitter accounts Buttons for competitions Business cards Display boards Banners and flyers Chairman’s Video Other promotional items
OUTREACH
Director l Eugene Lee
What do we do?
Keep track of service hours completed by team members
Coordinate Outreach events (Middle School Mentoring, Bots by the Bay, Scout Tours…)
One goal for next year: start and mentor FLL Teams and a FTC team
**IMPORTANT MESSAGE**
You MUST complete at least 10 Hours to go to a FRC Competition or World Competition – NO EXCEPTIONS!
