Robotc joystick
Is your robot moving up and down? Anyway, this can be done with the same method of mapping joystick arithmetic to each wheel. As for the holonomic arcade drive, I don’t understand what you mean by the z-axis. I can be done, just think about how the joystick relates to each wheel.
ROBOTC JOYSTICK CODE
It will make your life much easier, and programming faster, if you map each wheel to a mathematical function of joysticks just like the example code above. For example, if you move forward, moving the right joystick will do nothing as long as the left joystick is about the threshold. However, since everything is in “if else” form, you cannot do more than one behavior at once. Will this work? Is it efficient? How can I make the robot move like the traditional arcade style but without the spin (Use the left joystick for x, y, and z movement) and when I want to spin in place use the right joystick?ĭepending on how you have your motors flipped, the code that you posted should allow you to drive your robot. If((abs(joy_y) > joy_threshold) & (joy_y > 0))Įlse if((abs(joy_y) > joy_threshold) & (joy_y joy_threshold) & (joy_x > 0))Įlse if((abs(joy_x) > joy_threshold) & (joy_x < 0)) the robot.įor my “lynfield drive”, I want to be able to control the left joystick for forwards/backwards and the right joystick for horizontal/spin. Since the motors are on different sides of the robot, you want them doing different things sometimes so that you can turn. If y is 127, and x is -127, then both motors stay still.Īgain, you can fill in the rest of the table. If y is 127, and x is 127, then both motors go forward. If you have the same equation for both motors, then lets look at what would happen: You can fill in the rest of the table using the values 127, 0, and -127 on each of the axis to see what would happen. If y is 127, and x is -127, then the right motor goes forward while the left motor stays still. If y is 127, and x is 127, then the left motor goes forward while the right motor stays still. If y is 127, and x is 0, then both motors go forward. To see why the code provided achieves this behavior, plug in values to test the output. The back and forth motion of the robot is controlled by the y axis of the joystick, and the turning of the robot is controlled by the x axis of the joystick. VEXcode includes built-in tutorials and an extensive help resource, making Drivetrain commands and setup configuration easier and quicker than ever.This code is for the arcade style of driving, where one joystick controls the chassis movement of the robot. Students will use the same tools and programming languages that professionals use every day, developing their coding skills, acquiring workforce readiness, and enhancing their identity as a programmer. VEXcode Text provides students with an authentic programming experience. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface. VEXcode Blocks has been designed to allow those who are new to robotics to get their robot up and running faster. Each block's purpose can easily be identified using the visual cues like its shape, colour and label. Students use the simple drag and drop interface to create functioning programs. VEXcode Blocks is the perfect platform for those new to coding. As a result, students can focus on creating with technology, not trying to navigate a new layout. As students progress from Key Stage 2 to 4 and from VEX IQ to VEX EDR, they never have to learn a different blocks, code, or toolbar interface. There are two distinct environments for VEXcode: Blocks and Text, and they are consistent for VEX IQ and VEX V5. Developed by VEX for VEX, the intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is a way to program VEX V5 and VEX IQ that meets students at their level.
