TETRIX 12V DC Motor (regular, Torquenado)
Modern Robotics/MATRIX 12V DC Motors (this also includes goBILDA motors, which are MATRIX motors with a different gearbox)
Most motors above have very similar structures. They consist of the following components.
\nBare motor. In all cases above, this is a 12V motor of RS-555 type, with free speed\n around 6,000 RPM and stall current around 10A. The motor specs posted by different vendors might be slightly\n different, but the difference is mainly due to different testing methods.
Gearbox. The gearbox is attached to the front of the motor and reduces the speed\n while increasing the torque. For example, a 20:1 gearbox reduces the speed by a factor of 20, resulting in\n a no-load speed of around 300RPM. The gearbox can also be replaced; this is FTC legal but requires some skill.
Encoder. Attached to the back of the motor and protected by a plastic cap,\n the encoder contains a sensor registering motor shaft rotation. It can be connected to REV hubs and used for\n precise control of motor speed or rotating to a specific position.
\n {codeString}\n The FTC SDK is stored in a repository called “FtcRobotController” under the FIRST-Tech-Challenge GitHub\n organization:
\n \n\nFor simplicity, instead of cloning or forking the repository. we will provides instructions on downloading the repository\n as a .ZIP file.
\n\nFrom the main repository web page, click on the “releases” link to jump\n to the Releases page for the repository. The Releases page should list\n the available software releases for the repository. The latest release\n should be displayed near the top of the page.
\nClick on the Source code (zip) link to download the compressed Android\n Studio project folder.
\n\nOnce you have downloaded the archived (.ZIP) project file, you must\n first extract the contents of the archived project file to a folder where\n your future robot controller code will be saved. For Windows\n users, right mouse click on the file and select “Extract All” from the\n pop up menu. Windows should prompt you to select a destination for the\n extracted project folder.
\n\nIn order to import the Project, you will need to launch the Android\n Studio software on your computer. On the main Android Studio Welcome\n screen, select the option to “Import project (Gradle, Eclipse, ADT,\n etc.)” to begin the import process.
\n\nAndroid Studio should prompt you to select the project folder that you\n would like to import. Use the file browser in the pop up dialog box to\n locate and then select the folder that you extracted in an earlier\n section of this document. Make sure you select the extracted project\n folder (and not the .ZIP file which might have a similar name to the\n extracted folder). Hit the “OK” button to import the selected project\n into Android Studio.
\n\nIn the figure above the project folder called “FtcRobotController-6.0”\n is selected to be imported into Android Studio. It might take Android\n Studio several minutes to import the project. Once the project has been\n successfully imported, the screen should look similar to the one\n depicted in the image below.
