These are libraries which help the FTC App work on various Android Devices. SDK PackagesĪfter Android Studio is installed, there are several add-on components which also need to be installed. Save the FTC App in a smart location with other FTC-related files. Getting the latest versions of everything is a good idea. In general, you’ll want to install everything in the order listed above. To get the latest “stable” release, you can use the green “Clone or Download” button and say “Download ZIP.” If you want a beta version of the SDK, you may wish to go to the selection that reads “Branch: master” and choose “beta” first. When we write programs, they’ll be added to this app in order to make the robot do what we’re saying. The FTC App SDK is a set of pre-written code that makes robots work.We’ll use it to write our programs, compile them, and download them to the Robot Controller phone. This needs to be installed on the computer in order for Android Studio to work correctly. We’re going to write programs in the Java language, and the JDK will translate our code into something the robot can understand. The Java Development Kit (JDK) is our translator.Following is an overview of the various pieces and what they do: There are a few different items to install. This guide isn’t comprehensive, but it can point you in the right direction. In written form, as part of the PushBot Build Guide (see page 52, as of revision ).In training module form, from Intelitek.There are many resources available to help in the process, this guide being one of them. It can take some time (and bandwidth), so be prepared to see the process through to the end. You will also need to turn on USB Debugging on the phone and allow the computer to connect to the phone first.For many teams, getting Android Studio up and running will be the first step towards testing hardware, demonstrating a proof-of-concept in motion, or driving a robot. You will need to configure what motor port corresponds to what name on the phones when you hook up the hardware. That’s it! You should be able to press the green play button in the toolbar and upload code to your Robot Controller and run this code on your tank drive. We can apply the negative sign to the value from gamepad1.left_stick_y to reverse its direction and ensure the left motor moves the robot in the same direction as the right motor like mentioned earlier. A file with something similar to the following code should show up: package /** * Created by nicholas on 9/5/17. A window should pop up, but all you’ll need to enter is the name of your OpMode. To create a new OpMode right click on the folder and select new -> Java Class. The OpModes you’ll write go inside of TeamCode -> java ->. It’s similar to a file manager, but specifically for Android code. On the left in Android Studio there is a list of the files inside of the SDK. Basically it’s just a folder with many files that have code inside of them. The SDK FIRST developed is a library of code that you can use to control your robot. Go to File->Settings in the toolbar and search for instant run and make sure it’s unchecked. Next you should disable Instant Run in Android Studio because sometimes it stops new OpModes from showing up on the phones, and occasionally stop OpModes from updating with new code. You should click the links for Update Build Tools.Ī status bar like below shows the status of your program compiling or uploading to the phone. Open up the SDK inside Android Studio, You may see a notification like this:Ĭlick Update to make sure you’re on the latest version. Here is a good tutorial on how to do that. You should have Android Studio and the FTC SDK downloaded. I’ll assume you have some basic knowledge of the FTC hardware. This tutorial will show how to create basic OpModes for Teleop. In this tutorial I plan to cover some of those concepts and basics. FTC programming contains lots of concepts that are very specific to robotics and not regular programming.
