Kapp: Added to tube grabber

{{RobotInfoBox

|Competition=FRC
}}

This robot was designed mainly by [[Keefer Dunn]] and [[Patrick Harrington]].

==Mechanics==
===Tube System===
The tube system consisted of the tube grabber and a tube elevator. Each performed a role in making sure the robot successively could grab a tube and place in gently on the rack.

====Tube Grabber====
The tube grabber was a small module containing one Fisher Price motor to turn a [[unobtainium]] roller that would hold the tube in the tube grabber. The bottom of the tube grabber had flat plastic "fingers" that would support the bottom of a tube as it was being moved up and down during game play. When a tube was taken in, it'd be rotated upward at about a 30 degree angle so the tube could be easily placed on the rack.<ref name="CDBrandon">[[Brandon Adams|Brandon Adams']] [http://www.chiefdelphi.com/forums/showpost.php?p=599364&postcount=5 Chief Delphi Post]</ref>

The tube grabber would move up in down via the tube elevator by 80/20 wheeled linear slides.{{citation needed}}

====Tube Elevator====
The tube elevator consisted of the 80/20 supports and the rope winch.

The 80/20 supports that held the tube grabber in place as it moved up and down during game play was actually two long pieces of 80/20. Due to the sizing restriction at the beginning of a match, the two 80/20 pieces would be folded down in the shape of a triangle until the match began. After the match began, a pre-compressed pneumatic cylinder would push up the top half of the structure until it was locked in by a simple locking mechanism thought up of by [[Sunny Gupta]]. Pneumatics was no longer needed for the remainder of the match.

The rope winch was a simple winch that was placed at the bottom of the robot with small CIM with a BaneBots gearhead and encoder.<ref name="CDBrandon"/> The rope from the winch went up to the top of the elevator, around a pulley, and back down to the tube grabber. The system only pulled on the tube grabber when it needed to go up, relying on gravity to pull it back down.

During scrimmage, the tube grabber would get jammed in the elevator structure causing the rope winch to put a lot of tension on the rope, causing it to break. It was fixed by using a stronger rope.

===Drivetrain===
The drivetrain of the robot was a four wheel drive with two IFI "sticky" wheels in the front and two omniwheels in the back.

==Control==
[[Image:Thunderhorse Controls.jpg | thumb | right | Picture of the driver station for Thunderhorse with Guitar Hero and XBox 360.]]
Control of the robot was done by a XBox 360 controller for driving and a modded Guitar Hero controller for manipulation of tubes.

===Driving===
Driving of the robot was done by a XBox 360 controller using the [http://firstwiki.net/index.php/USB_chicklet USB Chicklet].

===Manipulation===
Manipulation of the robot was done by a modded Guitar Hero controller that was interfaced directly to the digital IO's.

The five buttons on the neck were used for high/medium/low positions for the tube elevator and manual up/down for fine tuning. The strumming on the guitar was used for a manual load/unload of a tube, and the select button was a on/off toggle for the auto-load function.<ref name="CDBrandon2">[[Brandon Adams|Brandon Adams']] [http://www.chiefdelphi.com/forums/showthread.php?postid=601575#post601575 Chief Delphi Post #2]</ref>

Unobtanium is a very precious material that team 1261 often incorporates into robot designs. Its natural form is a black, squishy tube. Its primary feature is its very high coefficient of friction, making it extremely useful for gripping various game pieces.

Unobtanium has been incorporated into the following robots:
Thunderhorse
Logan Rover
Chimichanga

Swervin' Mervin'

Swervin' Mervin was an awesome robot. It was able to reliably score multiple balls in the center goal in Aim High. Combined with its highly maneuverable swerve drive and it's ability to pick up balls by driving over them, it was a force to reckon with, and it won the 2006 Peachtree Regional.

Due to weight issues, the robot had to be "Swiss-cheesed", a process in which the noncritical components are cut with a hole saw in order to reduce weight.

==Drivetrain==
Swervin' Mervin' had a very special drivetrain - swerve drive. In short, this allowed the to move in any direction very easily by simple rotating the direction of the wheels individually.

Peachtree Regional

The Peachtree Regional is perhaps the best [[FIRST Robotics Competition|FRC]] regional in Georgia, course it is the only one.

Team 1261 has attended the Peachtree Regional every year since 2004, because it is the closest regional to the team.

==Game Announcer==
The Peachtree Regional has had [[Sir Charles]] for the game announcer. In [[2010]] he was not the game announcer due to the Peachtree Regional being moved up to Week 1 and [[Sir Charles]] being game announcer at the another regional.

===Deals with Sir Charles===
During [[2007]] ([[Rack 'n' Roll]]), [[Sir Charles]] made a bet with the robots at the Peachtree Regional that whomever was the first alliance to score all the way around the field element (a total of 256 points) he personally would buy the alliance donuts. Team 1261 successfully did this and was personally brought Dunkin' Donuts by Sir Charles at one meeting after the regional.

The Palmetto Regional is a regional in South Carolina hosted at Clemson.

The Robolions have attended the Palmetto Regional every year since 2008.
