Cool Project: VEX2-D2

without comments

CP - VEX2-D2

 

VEX IQ super user, Damien Kee, has made another very cool project! This time he found inspiration from one of our favorite robots, R2-D2, to create VEX2-D2.

Made completely with VEX IQ parts, he used 3 motors to program the movements – one for each leg and one for the head. Damien says he hopes to have a set of building instructions for it sometime in the near future (and when he does, we will link to them here.) Check out the video below then visit Damien’s website to learn more about VEX2-D2 along with other resources he has to offer.

The VEX and VEX IQ Programming Skills Challenge for Robot Virtual Worlds 2017

without comments

Robomatter, VEX Robotics, and the REC Foundation are excited to present low cost, high quality virtual competitions that enable students to test their problem solving and programming skills in the VEX Starstruck and VEX IQ Crossover Robot Virtual World Competitions. And, not only do these virtual competitions provide a great learning experience, you could also qualify for the 2017 VEX Worlds Championship!!
 

This Year’s Games

Both games simulate the single-player Robot Skills and Programming Skills modes of the physical Starstruck and Crossover competitions. However, only the Programming Skills modes of the Virtual simulations are awarded prizes. To participate in the competition, you must update your Robot Virtual World software.

 

starstruckflair

In the Starstruck Robot Virtual Worlds Competition, your goal is to score as many stars and cubes in your zones. You then must hang your robot on your hanging bar.

 

 

crossoverflair

For the Crossover Robot Virtual Worlds Competition, you must pick up the hexballs, score them in their colored scoring area, and then balance on the bridge.

 

Winners Qualify for VEX Worlds!

virtual-challenge-2017

The winners of the Robomatter sponsored VEX Starstruck and VEX IQ Crossover Virtual World competition will receive an invitation to the VEX World Championship April 19-25, 2017 at the Kentucky Expo Center in Louisville Kentucky!

Important Deadlines:

  • Submissions for both contests are due by January 11, 2017.
  • Winners will be announced by February 1, 2017

Exciting News with ROBOTC for VEX Robotics 4.55!

with 2 comments

ROBOTC 4-55 VEX

 
The ROBOTC Development Team has a brand new update for you, ROBOTC 4.55! A full list of changes and improvements appear below. But we have BIG NEWS to share first…

We are excited to announce that the software required to program VEX robot hardware is finally included with every VEX IQ and VEX EDR kit at no extra charge! Current VEX users can now download the no-cost version of ROBOTC 4.x for VEX directly. Follow these steps to download:

1. Login to your www.vexrobotics.com account. If you don’t have an account, create one at https://www.vexrobotics.com/customer/account/create/

2. Navigate to Software Downloads under “My Account” on the left side of your Account Dashboard.

3. Choose your desired software and follow the download and installation instructions.

 
And here are the highlights of the latest update:

 

Create Graphs from your Datalogs

 

Datalog Graph

Want to know what running your robot into a wall looks like to your accelerometer? Curious about how ambient light intensity varies throughout the day? Datalogging now supports (live) plotting of incoming data gathered on the robot brain. Science experiments involving sensor and motor data can be displayed. You can easily find out by gathering the data and having ROBOTC plot the data for you, as it comes in.

 

Datalog Graphical

Datalogging is no longer restricted to just Full ROBOTC, we’ve added easy to use blocks that allow you to access the same functionality in a simple manner.

Additionally, logged data can even be exported for further analysis in a spreadsheet application of your choice.

 

ROBOTC Graphical Variable Support

 

Variable Support

You can now use variables in ROBOTC Graphical, as well as perform various operations on them. You can add, subtract, divide, multiple, whatever your program requires. You can use variables in loops, motor blocks, you name it!

 

ROBOTC Graphical Break and Continue

 

Continue Break

We’ve added two new program flow blocks, break and continue. This was a much requested feature from our more advanced users of ROBOTC Graphical. You can now create more complex programs without creating work-arounds or having to switch to ROBOTC Full.

 

Beta Channel Access

 

Use Beta Builds

Want to have a front row seat when it comes to upcoming features in ROBOTC? Subscribe to the beta channel through ROBOTC’s preference menu and you will be notified when a preview build (such as this one), is released.

Support for VEXos Utility for VEX IQ

 

VEXos

VEXos is a robotics operating system that harnesses the flexibility and power of VEX hardware for the rigors of competition and the diverse needs of education. This operating system, written completely by VEX Robotics, uses real-time processing for repeatable operation at the fastest possible speeds. The “VEXos Utility” program simplifies updating VEX IQ hardware, and is compatible with Windows 7-10, and Mac OS X 10.8 and greater. Find out more about VEXos here!

Cool Project: VEX IQ Smart Radio and iOS

without comments

Cool Project - Smart Radio Blog
Our friend, Simon Burfield, put together a fantastic tutorial on how to get the your VEX IQ brain transferring data with your bluetooth enabled smartphone using the VEX Smart Radio and ROBOTC. Who doesn’t want to control their VEX IQ with a smartphone?!?!

And if you were at VEX Worlds 2016, you might have seen the VEX IQ Smart Radio in action with Simon’s robots. Check out a preview below:

 

To get started, you will need the following:

  • An iOS device with xcode installed
  • A way to run ROBOTC 4.5 +
  • The VEX firmware update program

The following video tutorial and steps below will guide you through the process:

Steps

1) Install the VEX Smart Radio firmware on to the brain
2) Enable Smart Radio in ROBOTC
3) Install the RobotC Smart Radio firmware on to the brain
4) Download the code https://github.com/burf2000/VEXIQ_iOS_ROBOTC
5) Plug a motor in to port 8, a Touch LED in to port 2
6) Install the ROBOTC (BT Demo) program on to the brick
7) Disconnect the brain from the PC
8) Find your Smart Radio ID and remember it (mine was 7436)
9) Run the ROBOTC program on the brain (remember not to be connected via USB)
10) Load code project up and deploy to a iOS device that supports Bluetooth LE
11) Enter your Smart Radio ID in to the App and hit connect

Once connected you should be able to control the motor and the LED!

You can find the original code by James Pearman here. And this is Simon’s code shown in the video tutorial.

Have questions? Head over to our ROBOTC VEX IQ Forum and we can help you out.

Happy Programming!

  • EV3 specific datalogging functions have been marked as obsolete. Users should use the new datalogging functions.
  • Restrictions on the file downloading locations on the EV3 have been relaxed a little.
  • Opening the File Utility on the EV3 will create the rc and rc-data folders, if they don’t already exist.
  • Playing a sound file from inside ROBOTC’s on-brick program folder is easier. It will check if a file with that name exists in the rc folder, before checking the built-in sounds folder.
  • A memory leak in the EV3 connection handling has been fixed; disconnecting an EV3 while the debugger was running would eventually exhaust all program memory.
  • Running a motor with a specified encoder count of 0 on the EV3 would produce unpredictable results, this has been fixed.
  • An issue with reading data from the NXT Sonar sensor in the IDE has been fixed.
