ROBOTC 456
 

The ROBOTC Development Team is excited to make our latest update available to you, ROBOTC for LEGO MINDSTORMS 4.56. This is primarily a maintenance release which contains many stability fixes. Keep reading for a full list of changes and improvements below.

Updates for all robot platforms:

  • When saving a C source file, you can now opt to keep a backup of the previous version of the file. This behavior can be enabled through the preferences.
    Sourcefile Backup
  • Under certain conditions, semaphores could be given to a task that had not unlocked it. This has been corrected.
  • Previously, the compiler would count both prototypes and actual function implementations separately, reducing the number of functions available to you. This has been corrected.

Updates specific to the LEGO MINDSTORMS EV3:

  • The way text files are saved has been changed to prevent the “65000 temp files” issue that some users were seeing.
  • WiFi has been removed from the communications pane. This is unsupported and was left visible as an oversight.
  • Joystick control for the EV3 has been fixed.
  • The EV3 sound code was partially rewritten for stability reasons.

Updates specific to the LEGO MINDSTORMS NXT:

  • Operation Reset samples were not working correctly, this has been fixed.

Student POV: How ROBOTC Changed the Way we do Robotics

without comments

HOW ROBOTC

We, as a team from the Federal Institute of Sergipe (Aracaju, SE, Brazil), have started to meddle with robotics about half a year ago. After some hard work with the hardware and mechanical aspects of the build, we headed to the most crucial thing: the algorithm, intelligence itself. There, we’ve hit an obstacle. A considerable one.

“Talos”, the Robot

“Talos”, the Robot

First, we’ve tried to use the LEGO Mindstorms EV3 software, the one where you use blocks to build programs directly to the brick. That, proved very unsustainable as we move along. The code kept getting bigger, and more unclear to work by as it grew. As we’ve kept getting the needs for a clear code interpretation and source sharing, it was no longer an option.

We’ve then tried a couple other options, as the LeJOS and EV3DEV, but as we we’re implementing an Arduino Pro Mini and an Arduino UNO, we needed a better grasp on the protocols that runs between them. We’ve decided to use I2C and found out that both of the options didn’t have the tools needed to debug and test with. That along with the inconsistency (the robot just didn’t work for no reason 1 out of 20 times), have presented us with a challenge.

There were times when we just didn’t know if a software/framework with the tools we needed existed. We still had an option, we had to try ROBOTC.

We haven’t done it before on one fact: It was paid. But it had a 10-day trial, and we still had to try. And it was fantastic.

We could instantly try it out, it had a firmware of it’s own (with a 1-click install, which makes thing extra-practical) and a really smooth learning curve. An extensive documentation, a really broad community and many many tools to debug from. But does it have an I2C test utility? Yes. It has. The code became clearer, the problems we’re gone, we could share the code on Github, it was magical. It even has a couple plans of payment for teams and or students.

I’d suggest ROBOTC to every EV3/NXT user, it is simply the best all-together tool out there.

ROBOTC 4-55

The ROBOTC Development Team is excited to share our latest official update with you, ROBOTC for MINDSTORMS 4.55, which includes new features, functionality, and bug fixes. A full list of changes and improvements appear below (including an awesome sale for 3.x users), but here are the highlights:

 

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.

Explore National Robotics Week with Robot Virtual Worlds

without comments

nationalroboticsweek_twitter

 
To help celebrate National Robotics Week, we’ve created a FREE, online version of our Robot Virtual Worlds software, which you can use in your classroom to teach students about robotics and introductory programming concepts.

For the week of April 4th (and the rest of April!) we’ve opened up a free, online version of our Ruins of Atlantis Robot Virtual World, as well as a number of other Robot Virtual World challenges.

 

We thought Atlantis was a myth. We were wrong.

 
ruins of atlantis screenshot with controlsExplore the Ruins of Atlantis, 6,000 meters below the surface of the ocean, collecting data and treasure as you do!

Ruins of Atlantis is one of our Robot Virtual Worlds, themed in a fantasy, underwater environment. It’s designed to teach and reinforce behavior-based programming in a fun and meaningful way. While immersed in a scaffolded programming environment, students practice robot programming, using a full set of virtual motors and sensors on exciting new robots, 6000 meters below the surface of the ocean.

The level design of Ruins of Atlantis features a path that includes collectible objects and additional starting points, making it ideal for teaching introductory programming concepts such as path planning and encoder based movements. Even though the robots in Atlantis do not resemble the real classroom robots, students can use the same programming languages (EV3, NXT-G, ROBOTC, etc.) to control them.

Visit our National Robotics Week website to get started!

 

More Robotics Fun!

 
In addition to Ruins of Atlantis, you can also access free, online versions of the following Robot Virtual Worlds Challenges:

  • Maze Challenge: This challenge features a sequence of turns that the robot must perform in order to get to the “end” of the maze. The robot must first begin at the starting point, and get to the goal area by completing turning and forward movement behaviors.
     
    maze challenge
  • Basic Movement 1 Programming: In this challenge, you will program your robot to pick up the three green cubes on the far side of the field and drop them into the green goal on the near side of the field, one at a time.
     
    basic movement 1
  • Basic Movement 2 Programming: In this challenge, you will program your robot to pick up one red cube, navigate to the red goal without bumping any of the walls, and drop the cube into the goal

Visit our National Robotics Week website to learn more!

 

Robot Virtual Worlds + Research-Based Curriculum = Excellent STEM Education

 
STEMWith lots of research from the Carnegie Mellon Robotics Academy backing it up, Robot Virtual Worlds is a great tool to create a scaffold learning experience that teaches students important math, programming, proportional reasoning, and computational thinking skills. That’s we’ve built Robot Virtual Worlds into our STEM Curriculum.

Our curriculum does more than simply teach students basic facts and concepts. We teach students skills they need to be successful in the real world. Here are a few highlights:

  • Learner-centered instruction built on research that’s been proven in the real-world
  • Helps students develop 21st Century college and career readiness skills
  • Teaches important skills in foundational mathematics, engineering, programming, problem-solving, creative thinking, and computational thinking
  • Designed to provide structured problem-based learning that:
    • Provides guidance to both students and teachers
    • Scaffolds difficult concepts and complex tasks
    • Schedules class time closely so that no class time is wasted
    • Requires students to generalize their understanding and apply learning across contexts

To learn more about our curriculum, visit our website or send us an email at STEMSolutions@robomatter.com.

Cool Project: Tumblebug

with one comment

TumbleBugBlogDamien Kee, a VEX IQ and EV3 Super User, has created another cool project! This time he used one of his kids toys, the Tumble Bug Ball Drop, to test out how often the ball comes out of the left foot / right foot with a 50% probability. Damien says, “My boys got this toy for Christmas one year and I thought I’d put together a little device to check the probability of how it works. I used Ultrasonic Sensors with the EV3 and Colour Sensors (Proximity mode) with the IQ to keep track every time a ball went through the toy…. This would make a great experiment to run in class, not just with the Tumble Bug but all different types of kids toys.” We couldn’t agree more!

Damien used the VEX IQ and LEGO EV3 programmed in ROBOTC to run his tests. The programs figure out the percentage and display them on screen. Here is a full breakdown video of how the project was done …

 
 
 

 

Not only does this project allow for the practice of programming, but it gives the opportunity to assess variables when determining the results. Damien says: ”

What I love about doing these sort of extended investigations in class, is that rather than being a final conclusion, this now opens up a huge range of other questions and scenarios that you can test.

  • Why was there a difference?
  • Was the table level?
  • Do the different balls have an impact?
  • Does the placement speed in the mouth affect the results?”

Want to try it out yourself? Here are the code files Damien used:
EV3 RobotC –  EV3_tumblrbug.c
VEX IQ RobotC –  tumblrbug_VEX.c

To see the full hardware setup and find out the final results, check out his full blog here – Testing the Tumblebug (EV3 and VEX IQ)

 

Do you have a cool ROBOTC project you want to share with the world? If so, send us an email at socialmedia@robomatter.com and we’ll post it on our blog and social media pages!
