 Before the [[Peachtree Regional]], the ball holder consisted of one Makita vacuum cleaner driven by a Fischer Price motor. The vacuum was connected to two AndyMark suction cups positioned in the front of the robot to grasp the ball.{{citation needed}} However, the design proved to be hard to get a good seal on the ball thus losing controllability, and also the kicker would interfere with the positioning of the two suction cups.
-After the [[Peachtree Regional]] and during the [[Palmetto Regional]], work was done to convert the suction system into a roller system that was pursued early in the build season, but conclusions came that the design would not work. Work by [[Sunny Gupta]] and [[Logan Su]] on the roller pinching system made the roller system what it was during the Palmetto Regional. The roller system consisted of one roll of unobtainium powered by a Window Motor.{{citation needed}} The soccer ball was pinched by a bottom bar positioned beneath the roller along the bottom of the robot. The bottom bar was a quarter piece of 80/20 coated in a plastic material for hand tools.

 The potentiometer controlled the power setting of the kicker. When the potentiometer was fully out (i.e. - no finger on it) the kicker was set to full power, while when the potentiometer was fully down (i.e. - finger fully pushed onto the potentiometer) the kicker was set to low power. When the potentiometer was in between these two values, kicker power was extrapolated out and correspondingly set. This allowed for freedom of control instead of being strapped to a fixed number of fixed power settings.
 ==Programming==
 The Chimichanga was programmed using [[LabVIEW]]. The arming and variable kick setting of the kicker was all automated using encoder values and a limit switch. The rest of the robot was pretty basic.

 ====Winch====
-The winch mechanism consisted of a Frischer Price motor that was attached to a AndyMark Super Shifter with an encoder. Early in the build season it was thought that the shifter might be needed to let the kicker actually kick, but the tension proved to be too much for the small pneumatic piston supposed to shift in/out of gear. The output shaft of the shifter consisted of a circular plate to keep wound rope on the spool.

 ===Kicking System===
 The kicking system consisted of the 80/20 kicker, the winch, and the sail clutch. Each performed a role in making sure the robot successively executed a kick.

	The Chimichanga was mainly designed by [[Tanner Smith]] and [[Sunny Gupta]]. Officially (as TIMS saw it), the robot was still named "[[Logan Rover]]" from [[2009]], though it was named the "Chimichanga" at the [[2010]] [[Palmetto Regional]].

 The robot was controlled using two XBox 360 controllers - one for driving and one for manipulation.
 ===Driving===
-Driving was in a arcade like mode using two independent joysticks on the XBox 360 controller. One was used for Y speed and one was used for rotational speed.
+Driving was an arcade-like mode using the two independent joysticks on the XBox 360 controller. The left joystick's Y-axis was used for the robot's forward speed, while the right joystick's X-axis was used for the robot's rotational speed. A press on either of the controller's thumb/index finger potentiometers limited the drive speed to a percentage of the full power.
 ===Manipulation===
-Manipulation control using the XBox 360 controllers was quite simple and probably could've been accomplished using a regular joystick. One button was used for arming/firing and another as a failsafe in case the kicker refused to arm. Power setting for the kicker was set as either one of the trigger potentiometers on the controller.
+Manipulation control was quite simple and could've been done using some other control device other than the XBox 360 controller. Only two buttons were used along with one of the thumb/index finger potentiometers.
