Code 5.vex

[Fatima Teem]

Fromelementary school through college, VEXcode is a coding environment that meets students at their level. The intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is consistent across Blocks and Text, across VEX GO, VEX IQ, and VEX V5. As students progress from elementary, middle, and high school, they never have to learn a different blocks, code, or toolbar interface. As a result, students can focus on creating with technology, not trying to navigate a new layout.Drive Forward is the new Hello WorldWe all know that robots attract kids to learn. VEX Robotics and VEXcode are providing opportunities for students of all ages to participate in learning the code that makes these robots work. VEX makes computer science come to life through collaborations, hands-on projects, and engaging experiences. From classrooms to competitions, VEXcode helps to create the next generation of innovators.Drag. Drop. Drive.VEXcode is the perfect platform for those new to coding. Students use the simple drag and drop interface to create functioning programs. Each block's purpose can easily be identified using the visual cues like its shape, color, and label. We've designed VEXcode to allow those who are new to robotics to get their robot up and running faster. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface.More accessible than everVEXcode even helps across language barriers, allowing student to read blocks and comment programs in their native language.Drag & Drop.

Along with the introduction of AVX, Intel introduced the VEX encoding scheme into the Intel 64 and IA-32 architecture. This encoding scheme is used mostly with AVX instructions. I was wondering if it's okay to intermix VEX-encoded instructions and the now called "legacy SSE" instructions.

I commonly use the first one to "broadcast" a scalar value to all the places in an XMM register. Now, the instruction set says that the only difference between these two (in this case) is that the VEX-encoded one clears the higher (>=128) bits of the YMM register. Supposing that I don't need that, what's the advantage of using the VEX-encoded version in this case? The first instruction takes 4 bytes (0FC6C000), the second - 5 (C5F8C6C000).

As detailed on page 128 in Agner Fog: optimizing subroutines in assembly, using legacy SSE instructions while (some) upper halves are in use carries a performance penalty. This penalty is incurred once when entering the state where YMM registers are split in the middle, and once again when leaving that state.

It's not safe. According to Intel's software developer manual, VEX.128 version zeros the upper half of the YMM register, legacy SSE version doesn't. Worst thing: some assemblers (like gas) may convert SHUFPS into VSHUFPS while creating object file (when -mavx flag is applied). I found exact same problem working with an assembly file.

I have recently been working with Arduino in my school work and I need to incorporate Vex parts(a motor and a push button) because that is all we have to make movements. I'm attempting to test how the parts work with arduino and i cannot get anything to work. All my connections are correct with how I put them into the program,so I'm not sure what im doing wrong.

A problem: the semicolon should not be there, it terminates the if statement and what follows will always be executed.

A question: How have you wired the push button? Does it have a pullup or pulldown resistor? If it is pullup, the if statement should look for the pin to go LOW when pressed.

Another problem: Once you set the motorpin HIGH, it will stay that way until it is set LOW, which you never do. The if statement also needs an else clause in which you turn the motor off.

MorganS:

You're supposed to put your own something there. Replace do_something() with your own code.

Red wire? Very few buttons have red, black and white wires. Can you show us a picture or a link. I've never heard of VEX before.

This is just a simple program with no fine tuning. We did spend quite a bit of time to try and get this to work better with reducing motor speeds etc. but the end result is virtually the same. In no configuration is it possible to carry out a simple task coding the robot arm like the STEM lab suggests. Is there anything we are doing wrong? Do you have any real live video of this STEM lab with an actual GO set where this works like the animation in the lab docs?

Gearing: If the arm is experiencing issues reaching 90 degrees, this could be due to an issue with added gears. I think I can see in the first video the build is very similar to the provided build instructions, but in the second video I can see some gears added onto the arm assembly. Remember that when gears are added, this alternates the rotation that would be experienced by the arm, potentially causing your arm to not move the intended 90 degrees.

Program Fine-tuning: Although it may seem simple, programming motor movements can be quite delicate. You might need to adjust the duration of the motor movements, the wait times between actions, or the motor power levels. I understand you have already tried this, but it might need some further adjustments.

For now I am trialling a custom build with custom code blocks to hide the complexity of the extra gearing. One thing that is a problem though is the fact that I cannot create build instruactions for it.

Thanks for informing us about this issue. We were able to reproduce the issue. While investigating we did find that the issue is not exclusive android, but it seems to impact some devices more than others.

We found that the GO brain was having issues when it was getting too many messages from the connected device. We were able to fix the issue and are currently working on testing to make sure that it is fully fixed and that the fix does not introduce any other bugs.

The fix was made to the VEX GO Brain firmware. This means that to get the fix, all your GO Brains will need to get updated. Thankfully, once we push out the update, VEXcode will automatically update any brain that connects and is out of date. You just need to make sure that your Android tablets are connected to the internet so that VEXcode can detect the update.

Just wanted to let you know that we pushed out the VEX GO firmware update. This should fix the issue with the motors. Next time you connect to your VEX GO Brains, you will be prompted to update them. Once that is done, you should no longer have that motor issue.

This program is designed for students who enjoy building with Lego technic elements, motors, and sensors. Each student will have a Lego Mindstorms kitwith over 500 pieces and create projects such as a basketball shooting hoops robot, a lifting gripper, a humanoid robot, or other projects of their choice. They will connect their creation to theblock programming App to make them move and react to the environment using sensors. This program will promote a challenging environment where students will develop building skills and basics ofcomputer programming.

This program is designed to engage students in science, engineering, robotics, and coding. Each student will program an autonomous robot and solve different challengesevery day.
