	+	This page houses the 2015 [http://wiki.robojackets.org/w/RoboCup RoboCup] Mechanical efforts. Mechanical tasks for the 2015 competition year can be most easily summarized as a complete redesign of the SSL fleet.

	+	== Background ==
	+
	+	=== Current Robots ===
	+
	+	<font size="2">The team has taken part in RoboCup every year since 2008*. Two different fleets of robots are used: a fleet designed in 2008, and a fleet designed in 2011. The 2008 fleet sports a solenoid powered kicker mechanism and a fixed dribbler. The 2011 fleet sports solenoid powered kicker AND chipper mechanisms, along with a fixed dribbler and encoders on the motors.</font>
	+
	+	=== Previous Issues ===
	+
	+	<font size="2">Due to an error in the tolerances of shaft components for the 2011 fleet, the drivetrain of these robots have suffered tremendously, resulting in decayed performance of the motors. This renders mostly all 2011 robots functionally incapable. Thus, the most reliable robots have been those designed in 2008. However, the 2008 robots lack encoders, and without these sensors, this makes control of the robots significantly more challenging for the software team.</font>
	+
	+	=== Improvements ===
	+
	+	<font size="2">Due to these challenges, it has been determined that a complete rebuild of the robots is required to continue to be competitive in the RoboCup SSL. Particular emphasis is being placed on designing passive mechanisms that aid the software team in having finer control over the robots and the ball.</font>

	+
	+	<span style="font-size: small; line-height: 20.7999992370605px">The team for the 2015 competition year has met several times to discuss the primary goals for a new fleet of robots. These requirements are outlined below, in order of highest priority to lowest priority.</span>
	+
	+	#Encoders on the motors

	+	#Lower profile solenoids

	+
	+	=== Secondary Goals ===
	+
	+	The team has also considered other desired characteristics of the robots that are not necessarily competition-oriented goals. The list is below (in no particular order).
	+
	+	#Improved tolerances for the omniwheel (previous designs have significant play in this subsystem)

	+	*Field Size:
	+	**For the 2014 year, two options were available for the field size:
	+	***Single-size field: 6050mm x 4050mm
	+	***Double-size field: 8090mm x 6050mm
	+	**For the 2015 competition year, the field size is locked in as the "Double-size field": 8090mm x 6050mm
	+	*Max ball speed - 8 m/s
	+	*Ball diameter - 43 mm
	+	*Ball mass - 46 grams
	+	*Ball material - DuPont Surlyn Ionomer [http://www2.dupont.com/Surlyn/en_US/ Dupont's Surlyn Page]
	+	*Coefficient of static friction of golf ball on felt carpet - .66
