'''Motor'''

This is apparently the motor they were using

"The motor that matched our needs best was the Maxon 6V motor # 11827 (we are planning
to overdrive it to 12V) with either a 4.4:1 or 5.4:1 gear head ratio."

-Aaron

'''Possible Solenoid'''

'''Update'''

Apparently, angled dribblers have been BANNED (as of 2003)

'''Dribbler Rules:''' (from: [http://agents.sci.brooklyn.cuny.edu/dev/rcj/rcj2006/soccer-rules2006.pdf])

5.6. Ball Movement.

5.6.1. A robot cannot "hold" a ball.
Hint: Holding a ball means taking a full control of the ball by removing all of its degrees of freedom. For example, this would mean fixing a
ball to the robot's body, surrounding a ball using the robot's body to prevent access by others, encircling the ball or somehow trapping the
ball with any part of the robot's body. If a ball stops rolling while a robot is moving ,or a ball does not rebound when rolled into a robot, it is a good indication that the ball is trapped.

5.6.2. The ball cannot be held underneath a robot.

5.6.3. The ball must be visible at all times.

5.6.4. Other players must be able to access the ball.

5.6.5 The only exception to rule 5.6.1 is the use of a rotating drum that imparts dynamic back spin on the ball to keep the ball on its
surface. This is called a "dribbler".

5.6.6. A dribbler must comply with Rule 2.7 Ball Capturing Zones; i.e., the ball cannot penetrate under the dribbler for more than 2cm. The
2cm is measured from the contact point of the dribbler on the ball.

==Mechanical System==
This page breaks down the mechanical system of the Robots. The problem has been broken down into five phases as follows:

* Have ya'll checked out [http://robocup.mae.cornell.edu/documentation/robocup/2002/2002ME.doc these] [http://robocup.mae.cornell.edu/documentation/robocup/2003/2003ME.pdf papers] [http://robocup.mae.cornell.edu/documentation/robocup/2004open/CornellRoboCupMechanicalDocumentation2004.doc yet?] They are definately worth looking at. --[[User:AndyB|Andy]] 23:47, 26 September 2006 (EDT)

==Announcements==

'''Update 10-12-06'''

I edited the Dribbler page with some useful info.

-Pat

Found bevel gears, but we will still need a coupler or custom shaft. Bevel Gears (sdp-si) part #:
A 1B 3MYK05040 - same gears, 1 to 1 ratio.

-Brian

'''What to do 10/12/06:'''

''Manipulator team:'' Continue reading documentation, try to make headway towards seleceting solenoids (for shooting mechanism) and motor (for dribbler). There is someone working on the solenoids in the electrical group, so when you have some information get with him.

''Drive Train Team:'' Select a set of bevel gears, coupler (if needed, may be able to avoid because of bevel) and specifically which gear box. After that is done, work on putting all these componenets in inventor and placing them in the robot dimensions.

-Ryan

'''Homework!!!'''

1) Go to Maxon motor's website. Look at 6 W DC motors. Look for accompanying gears ( keep in mind shaft length and diameter. Look on www.mcmaster.com if you cannot find maxon gears). Perhaps accompanying gearboxes. Also, note physical size of motor and output RPM.

2) Read Cornell Papers on Mechanical page.

3) Ponder on Dribbler speed and assumptions.

Due: October 2nd

==Roadmap==
*Phase 1
**Simple prototype with holonomic drive train made from the Vex Robotics kit (Complete)
*Phase 2
**Build a second fully functioning prototype
**Kiwi drive system
**Dribbler and shooter
**Built to competition dimensions and requirements
*Phase 3
**Detail design of entire mechancial system
**Five robots
**Design Presentation to ME department
**Technical Drawings (AutoCAD or Inventor)
*Phase 4
**Purchase parts and assemble robot fleet
*Phase 5
**Test system and update designs
