What should I do first with my ROBOTC code?
The first thing you should do with any RobotC code, is setup your motors and sensors, so that we can begin to program a drive. If you do not setup these motors, it will be a pain to change all of your motor names in your entire code once that is done.
How do I Tell my Robot to do anything?
Before we can tell our robot to do anything, we need to initialize the hardware. But don’t worry; as scary as this sounds, RobotC makes it rather trivial. Just open up the “Motors and Sensors Setup” dialog, accessible from the “Robot” menu. From here, you can define the motors and sensors that will be connected to your robot.
How do I program the robot?
Starting right at the beginning, the first thing that you have to do, in order to program the robot, is have a programming software and compiler! This is made simple with RobotC - www.robotc.net In the pictures, you can see the steps required to install RobotC, but just in case, they are also listed below: 1. Go to www.robotc.net 2.
How to use xmtr2 on ROBOTC joysticks?
In easyC in the joystick blocks, there’s just a dropdown asking you if you want it on joystick 1 (main) or joystick 2 (partner). In RobotC, the format for the partner joysticks exactly the same as the main joystick, but with “Xmtr2” appended to the end of the Channel (Ch) or Button (Btn) code (“Xmtr2” = “transmitter 2”).

What code is Robotc?
ROBOTC is a text-based programming language based on the standard C programming language. Commands to the robot are written as text on the screen, processed by the ROBOTC compiler into a machine language file, and then loaded onto the robot, where they can be run. Text written as part of a program is called “code”.
How do you write a program for a robot?
There are three steps involved. First, you get motors and sensors running using off-the-shelf drivers. Then you develop basic building blocks so that you can move the robot and read its sensors. Finally, use that to develop smart, complex software routines to create your desired behavior.

What is the difference between C++ and RobotC? - Quora
Answer (1 of 2): C++ is a programming language that was evolved from C by Bjarne Stroustrup. C++ essentially is an extended compiler and api from C. A pure (and complete) C++ compiler can compile C code. RobotC is an language and API (an api is just bunch of code and libraries in layman’s terms)...

Why do we use comments in programming?
Comments are used to annotate your code. They can be incredibly useful in providing information (explanations, todos, bugs, goals, etc.) about your code to yourself or other programmers. This is especially applicable when multiple people are working on the same project -- notes can be left for the other programmer to read. Comments can also be useful in reminding yourself about information -- it can be tricky to remember all of the idiosyncrasies of the program when there are hundreds of lines of code.
How to get to the robot help?

What is robotc programming?
What’s RobotC? RobotC is a programming language used to program robots participating in FTC competitions. RobotC is a text-based programming language. It does not use drag and drop blocks like NXT-G or LabView -- instead, it uses text to command (and conquer) the robot.
What is a pragma in robotc?
A pragma, or pre-processor directive, gives the compiler instructions on how and what extra stuff to compile. Pragmas have two main uses in RobotC:
How to drive a tank robot?
A tank type drive uses both joysticks, the left to control your two left wheels, and the right to control your two right wheels. This is probably the most simple drive program to write, however it is not very good when it comes to competitions, because you may need a joystick for something else. To turn the robot towards the left, you would move the left joystick back, and the right joystick forward. This would do a spot-turn to wherever you need it to. To turn right you would do the opposite. Driving forward has both joysticks forward, and backwards has both joysticks backwards.
How to purchase a robotc license?

Is setting up other sensors the same as setting up a gyro?
Setting up other sensors is the same thing as setting up a gyro, however, instead of "sensorGyro", it will be the sensor that you chose. Here are some sensor reset commands for the following:
Can you write functions in a pre-autonomous program?
At the very top of your program, after the motor setup but before the Pre-Autonomous, you have the option to write and/or include functions. Functions are programmed only once at the top, but you can call it within your Autonomous whenever you need to, this makes programming A LOT easier, and cleaner!
Is pneumatics the same as programming?
Pneumatics are a little different when it comes to programming, remember when we were setting up the sensors in the Pre-Autonomous? We are essentially doing the same thing, however now we are only providing a value of "0", or "1", and it is within an if / else if / else loop!
Why do we need comments in code?
It helps debugging. When you write some code, and the robot doesn’t do what you’re expecting, having comments placed throughout your program will help you evaluate the code you’ve written — does the code below do what the comment says it should do?
What happens if you don't comment on code?
Without comments, the next programmer will waste lots of time (a) figuring out what you did, or (b) assuming your code does X when it really does Y, and adding more code, assuming the stuff that’s there does X.
How to ignore joystick?
But the likelihood is low that your driver will push the joystick exactly “north” and not “mostly north but a little off to the east” (or west). So you want to ignore joystick information that’s less than, say ±5. That way if the driver pushes the stick all the way up (“north”), but doesn’t get it exactly right, the robot will ignore the slight off-angle (Channel 4) and put all motors forward. Similarly, when the joysticks are not in use, sometimes the joystick lever doesn’t rest exactly at the center (a value of 0), but is “stuck” a little in one direction or another. Here also, ignoring these small errant values is very helpful.
What is the joystick channel in RobotC?
In RobotC, it’s easiest to think of each joystick channel like a sensor. By “channel” I mean the north/south and east/west movement of each joystick lever, identified by the numbers 1 and 2 (next to the right-hand stick) and 3 and 4 (next to the left-hand stick). Movement of a joystick along one of these axes returns a value between 127 (all the way “north” or “east”) to -127 (all the way “south” or “west”). Hmm, 127 to -127, what convenient numbers!
How to shorten 2 lines of code?
One could shorten the 2 lines of left-side code and 2 lines of right-side code by combining them into one statement each by simply checking whether the absolute value of the given power level exceeds the maximum , and then keeping track of whether it’s positive or negative with sgn (rightPower). In this case, you’d have the benefit of carrying along one fewer constants, since we no longer need minPower:
How to turn on a motor in RobotC?
In easyC, if you want to turn on a motor, you drag over a motor block , tell the popup window which one you’re using, and give it a power level. In RobotC, you must type this stuff in yourself. To set a motor to a fixed power level, one would type something like: motor [rightFront] = 100;
Does RobotC compile?
Since RobotC requires you to type the information yourself (instead of the motor block “typing” it for you), spelling and punctuation matter. A lot. If the syntax is wrong, your program will not compile or (worse) it will compile but will not do what it’s supposed to do when downloaded to the robot.
Where does RobotC take its syntax?
RobotC takes many of its syntax logic from Java. Assuming motorA has been connected in the motor set-up than the motor can be told to move in this way.
Is RobotC based on Java?
Java is an Object-Oriented language, that also happens to use C/C++ syntax, and is somewhat based on C++; but RobotC certainly is not based on Java.
