Intro to Programming

Programming in FTC

Modes of the game• Autonomous– Robot moves by itself

• Tele-op and End Game– Robot responds to controls

The two languages allowed• RobotC• LabVIEW

RobotC

• Similar to C programming– Text based

• For Help: www.robotc.net/forums• Pros– Compiles faster– Smaller code

• NXT can hold more programs

• Cons– Harder to multitask– Doesn’t come with kit

LabVIEW• Similar to NXT-G

– Graphics based• For Help: http://forums.ni.com/t5/LabVIEW-for-LEGO-MINDSTORMS-and/bd-p/460

• Pros– Easier multitasking– More visual– Comes with kit

• Cons– Takes longer to compile– Larger code – Takes up more space on computer itself

RobotCProgramming the joystick controllers

• 2 Joystick controllers– One is joy1 other is joy2

• 4 sections of the controller– Buttons, TopHat, Triggers, and Joysticks

Buttons

• Every button has a number
