The Mohave Robotics team (7681B) shared with us that their team voted to kick off their VEX IQ season using ROBOTC Graphical instead of the regular version they used last year. Per their teacher, Bert te Velde, “We wanted to get more people involved with programming and ROBOTC Graphical was the logical step to allow everyone on the team to get involved, no matter what their prior level of experience.”
In November 2013, Mohave Middle School sent four 7th graders to Scottsdale Community College for a three month course in full ROBOTC. The results were worth the effort, with Mohave winning the VEX IQ Programming Award at the VEX IQ Arizona State Championship in March 2014, and placing 14th at the VEX IQ World Championship in April 2014. “And they did that with a modified clawbot, one ball at a time!” exclaims Glenn Clevenger, one of the team’s mentors. “It’s hard to believe that they went from scoring 1 point at their first qualifying event in January to scoring 40 points at the VEX IQ World Championship in April. These kids are proof that ROBOTC is not too difficult for a 7th grader to handle.”
If you are wondering why Mohave is moving to ROBOTC Graphical, it’s because they plan to have their 8th graders teach all of the 6th and 7th graders that participate in VEX IQ how to program this year. The 8th graders decided it would be faster to get the new team members up to speed on the graphical version, without having to worry about syntax errors. And they can always convert their program to full ROBOTC if they need to later into the season.
After months of work, the ROBOTC Development Team is excited to announce the availability of the first preview release of ROBOTC Graphical Language for the VEX IQ platform. This new interface will allow you to program robots from inside ROBOTC with easy-to-use graphical blocks that can be drag-and-dropped to form a program. Each block represents an individual command from the “text-based” ROBOTC and Natural Language. The new click and drag interface along with the simplified commands of Natural Language will allow any robotics user to get up and running with programming their robots as soon as possible.
The first release of ROBOTC Graphical Language is available for the VEX IQ platform for use with the standard VEX IQ Clawbot and Autopilot Robots. All ROBOTC 4.0 users will receive access to the new Graphical Language interface at no additional cost! Our plans over the next few months are to extend the Graphical Language interface to all of ROBOTC’s support platforms, including the Robot Virtual Worlds technology. You can download the preview version today at http://www.robotc.net/graphical/.
The new ROBOTC Graphical programming environment adds a number of new features we’d like to highlight:
Graphical Language Command List (Drag and Drop)
With the new ROBOTC Graphical Mode, we’ve updated our “Functions Library” to match the style of the Graphical interface. This new mode will allow you to drag and drop blocks of code from the “Graphical Functions” menu into your program to get your program created even faster!
New Language Commands for Easier Programs
We also added some new language extensions to both ROBOTC and Natural Language; such as the simplistic “Repeat” command. Prior to the Repeat command, users would need to copy and paste large sections of code or use a looping structure (like a ‘for’ or ‘while’ loop) in order to have a set of actions repeat a number of times. With the new “Repeat” command, however, users can simply specify how many times they would like the code to run, with no complex coding required. And users who wish to make an “infinite loop” can use the “repeat forever” command to accomplish this task quickly!
Commenting Blocks of Code!
Another awesome tool that we’ve implemented in ROBOTC Graphical is the “comment out” feature. You can now comment out an entire line of code just by clicking on the block’s line number. The robot ignores lines of code that are “commented out” when the program runs, which makes this feature very useful when testing or debugging code. This new tool is unique to ROBOTC’s Graphical interface.
Updated and Simplified Toolbar
Sometimes navigating menus as a new user can be a little overwhelming – so many options to choose from and lots of questions about what each option is used for. To help with this, we’ve redesigned ROBOTC’s toolbar to make getting up and running easier. We put the most used commands on a larger toolbar so new users have an area to easily click to download firmware, send their code to their robot, and run their programs without having to use the standard menu interface.
Convert to Text-Based Natural Language
Because each Graphical Natural Language block corresponds to a real ROBOTC or Natural Language function, users will be able to graduate from Graphical Programming to full text-based programming with the press of a single button. This allows users to naturally transition from Graphical Natural Language to the text based Natural Language (or ROBOTC), without having to worry about manually converting the code line-by-line!
Teacher’s Guide and Sample Programs
The new graphical interface includes over 50 new sample programs to help you get up and running with working examples and demo code. In addition, we’ve also developed a 30+page guide to walk new (and existing) users through the new Graphical Programming interface and getting started with the VEX IQ platform. You can find a link to the programming guide here and also on the ROBOTC Graphical page.
This initial release is only the beginning and we’re planning on improving the software with more features and flexibility over the coming months.
- Copy and Paste
- Undo/Redo Support
- Support for custom robots/configurations via an updated “Motors and Sensor Setup” interface.
- Dynamic Loop and Command Parameters (based on Motors and Sensor Setup / Robot Configuration)
- Tooltips, Contextual Help, and more!
Let us know what you think! If you have any feedback or questions, please send them along via the ROBOTC’s VEX IQ forums.
We know that text based languages (such as ROBOTC) have advantages in terms of customizability with functions, complexity with algorithms and calculations, and typically smaller sized programs over graphical languages; however, it is difficult to overcome the simplicity and ease of use that “Drop and Drag” programming languages offer to new users just getting started with programming.
A few years ago (with ROBOTC 3.X), we announced our “Natural Language” feature – a simplified library of commands that used “natural” commands to control your robot, such as Forward, Reverse, and LineTrackForTime. The Natural Language feature was designed to help ‘bridge the gap’ between a graphical language and the text-based ROBOTC. Teachers have praised ROBOTC’s Natural Language for making it easier to get their students up and running faster than ever before. Currently, ROBOTC supports Natural Language on the VEX Cortex, VEX IQ, and LEGO MINDSTORMS NXT platforms for both “Real” and “Virtual” robots.
Today we’re proud to give you a sneak peek to a new feature we’re calling “Graphical Natural Language”. This new interface will allow you to program robots from inside ROBOTC with easy-to-use graphical blocks that can be drag-and-dropped to form a program. Each block represents an individual command from the “text-based” ROBOTC and Natural Language.
Each block is custom designed to fit the needs for that specific function and parameters. Using text boxes and drop-down menus, users can customize each values of each function to solve various challenge and activities using the same commands as ROBOTC’s Text-Based Natural Language.
We have also added some new language extensions to both ROBOTC and Natural Language, such as the simplistic “Repeat” command. Prior to the Repeat command, users would need to copy and paste large sections of code or use a looping structure (like a ‘for’ or ‘while loop) in order to have a set of actions repeat a certain number of times. With the new “Repeat” command, however, users can simply specify how many times they would like for the code to run, with no complex coding required.
Another awesome tool that we’ve implemented in ROBOTC 4.0 is the “comment out” feature. You can now comment out an entire line of code just by clicking on the block’s line number. Lines of code that are “commented out” are ignored by the robot when the program is run, which makes this feature very useful when testing or debugging a program. This new tool is unique to Graphical Natural Language.
Because each Graphical Natural Language block corresponds to a real ROBOTC or Natural Language function, users will be able to graduate from Graphical Natural Language to full text-based Natural Language with the press of a single button. This will allow you to naturally transition from Graphical Natural Language to the text based Natural Language (or ROBOTC), without having to worry about manually converting the code line-by-line!
