2011 Robotics Game

This year's game is LOGO MOTION!

LOGO MOTION is played by two competing alliances on a flat 27’ x 54’ foot field. Each alliance consists of three robots. They compete to hang as many inflated plastic shapes (triangles, circles, and squares) on their grids as they can during a 2 minute and 15 second match. The higher the teams hang their game pieces on their scoring grid, the more points their alliance receives.

The match begins with one 15-second Autonomous Period in which robots operate independently of driver inputs and must hang Ubertubes to score extra points. For the rest of the match, drivers control robots and try to maximize their alliance score by hanging as many logo pieces as possible. Any logo piece hung on the same peg as an Ubertube receives double points. If teams assemble the logo pieces on their scoring grids to form the FIRST logo (triangle, circle, square, in a horizontal row in that order), the points for the entire row are doubled.

The match ends with robots deploying minibots, small electro-mechanical assemblies that are independent of the host robot, onto vertical poles. The minibots race to the top of the pole to trigger a sensor and earn additional bonus points.

Fifth Day of build


 
Reminder to everyone that there will be a build meeting tomorrow at 10.
Bring a lunch, and your ideas!
Also a reminder for after school meetings, bring an extra sandwich or
something to eat, so that you stay healthy during build season.

Build log Day 5
 
Chassis
Discussed Speed Vs Strength (speed is highest priority)
Discussed how a fast robot is a better defense than a strong robot
Things to do
Do the math for gear ratios for 15 fps high gear
Order wheels, gear boxes and other parts for chassis
Claw & Arm
4 bar linkage would be possible without the need of an extension
4 bar linkage may not be necessary, and a 2 joint arm may work just as
well
weighted table was set up for the claw
students to come with drawings tomorrow to determine the best option
for claw
things to do
Pick an arm design, and make a prototype
Pick a claw design and make a prototype
Make sure claw and arm design work with each other and fit with in the frame
Programming
Deployed code onto 6wd chassis and got it driving
Wireless not working and had to tether it
things to do
Use light sensors and program them to get light detection
Right an algorithm to follow a line
Electrical
Wired up 2 light sensors
Wired up wireless bridge using 5 volt converter
Things to do
Wire up festo valve for pneumatics
wire up 3rd light sensor
Test old victors and jaguars to see what we have left
Field Build
Most field elements are built and transported to gymbags
things to do
Build field sides
Tape carpet down
Build hanging pegs
put everything together

Kickoff!

Attention: open in a new window. PrintE-mail

Kickoff was a very important day for the entire team! (Shame on you if you didn't come!) Hopefully everyone had a good time, I know I did! We watched the feed and saw the rules and the game, which were very surprising to see! (See the rules here ) We had Bumpers (best pizza around!) and we discussed many different aspects of the robot, which was a very successful brainstorm! Many thanks to the Bruce Power for allowing us to use the Visitor's Center!

A reminder to all team members

That the end of Kickoff means meetings every day after school! So be there, or be square! -Aaron
