We continue the new section to our blog called Teacher’s POV (Point of View) with another post by Jason McKenna, a K-8 Gifted Support Teacher in the Hopewell Area School District outside of Pittsburgh, PA. He took the time to give some examples of how you can use Robot Virtual Worlds in your classroom.
Robot Virtual Worlds is a powerful tool to teach ROBOTC to students. The unofficial motto for Robot Virtual Worlds is “No Robot, no problem.” That is absolutely true. If you are just starting a robotics program, or if your budget just can’t handle the cost of physical robots, Robot Virtual Worlds is a powerful tool for teachers.
However, the use of Robot Virtual Worlds is not just limited to replacing physical robots. Even if you have dozens of physical robots at your disposal, Robot Virtual Worlds can still be a powerful addition to your curriculum. Here are some examples:
- Differentiating Instruction. One of the hardest things for a teacher to do is to teach to where each individual student currently is in the curriculum. Robot Virtual Worlds allows teachers to do this. Let’s say you have a student that is struggling to learn some of the beginning ROBOTC concepts and another that is breezing through the curriculum. With Robot Virtual Worlds, you can easily create a challenge for each student. Creating a challenge for a student is easy. A new challenge can always be created in the Robot Virtual World Level Builder. Additionally, if students are working in Palm Island or Operation Reset, one student can program their robot to make turns while using timing, and the student that is progressing faster can be shown how to use the Gyro Sensor. In this manner, a teacher can differentiate instruction within the SAME lesson. That is the goal for all educators, and it can be achieved easily with Robot Virtual Worlds. To use another example, let’s say a student quickly solves a basic movement challenge (ex. Robot Slalom) with a physical robot. Instead of having to wait for the rest of the class to finish, that student can use the Curriculum Companion Pack to solve the same challenge virtually. Only now, the student can use encoder values to move precise distances, instead of just timing.
- Teaching to Mastery. Because Robot Virtual Worlds allows you to teach programming concepts faster (Physical vs Virtual Programming Fall 2012 Study Results), it also affords teachers the opportunity to present more repeated practice to the students. Missions in both Operation Reset and Palm Island reinforce all of the fundamentals of programming that are found in the ROBOTC Curriculum. For instance, if a student has just learned how to line follow with their physical robot, they can then complete missions in both Operation Reset and Palm Island that also require line following.
- Introduction to New Students. As teachers, our days are filled with the unexpected. One of the most challenging surprises is when you are told that you will have a new student in class because the student just moved to your district. Your class is 3 or 4 months into the ROBOTC curriculum, and your new student has no experience with ROBOTC at all. Here is where the Robot Virtual Worlds came be a lifesaver. Instead of having the student jump into whatever challenge the students are doing with physical robots, the student can watch the lessons from the ROBOTC Curriculum and complete the challenges in the Curriculum Companion Pack. After the student has begun to learn some of basics of ROBOTC, he/she can be introduced to the challenge that the rest of class is working on.
- Beginning of the School Year. When students return from summer break, some will have retained all or most of what was taught to them the previous year. Others will have retained far less. With this example, Robot Virtual Worlds can be used as a pre-assessment that can then be used to help direct that teacher’s instruction. For example, a teacher can create a challenge in the Robot Virtual World Level Builder that asks the students to utilize different programming concepts. By doing this, a teacher can see what skills need to be reviewed and what skills the students have retained. This is a tremendous time-saver. Most teachers work under the assumption that they had better review everything before moving on to a new concept. Using a pre-assessment eliminates this need. Robot Virtual Worlds are a perfect fit for this pre-assessment.
- Robot Virtual Worlds Levels Builder. This is a great tool for, once again, those unexpected occurrences in the classroom. Let’s say you you’ve been pulled into a meeting without a previous notice. A substitute has been sent to your class for coverage. You’re a little hesitant to let the students practice with the physical robots because the students are just beginning and the sub will not be able to answer any of their questions. You don’t have time to introduce a challenge in one of the Virtual Worlds; therefore, you quickly tell the students to open the Levels Builder and tell them to create challenges for each other. The students are now engaged and busy, and you can proceed to your meeting.
Those are 5 quick ways that Robot Virtual Worlds can be a big help for any teacher, not matter how many physical robot a teacher may or may not have. Robot Virtual Worlds are not just a replacement for physical robots, they are a tremendous asset in and of themselves.

We designed the RVW Model Importer so students and teachers can expand upon the learning already going on in their classrooms. We released the first version with support for importing Stereolithography format (.STL) files because these allowed models to be made using the engineering industry-standard Autodesk Inventor and Solidworks solid modeling software packages already used in many classrooms. Unfortunately, there's no such thing as a universally-supported format for 3D models, so, while we hope to release support for more formats in the future, we knew we were excluding some powerful and easy to use tools.
One of these was SketchUp, an easy-to-learn 3D modeling program originally created by Google and now developed by Trimble. (We like it enough that we even made a set of introductory tutorials.) Thus, we were happy to discover there's now a plugin for SketchUp that allows models to be exported as STL files. Here's a set of instructions to get you started. These were developed using SketchUp 8, but should work as well using newer versions.
1. Make sure you are logged in on your computer as a user account with Administrator privileges.
2. If you don't already have it installed, download and install SketchUp. You can get started learning how to model either using our tutorials on CS2N or the Getting Started guide developed by Trimble.
3. Download the plugin file from https://github.com/SketchUp/sketchup-stl/raw/master/sketchup-stl-1.0.0.rbz.
4. Open SketchUp, then open the Window menu and choose Preferences, then select the Extensions page.
5. Click the Install Extension button and select the plugin file you downloaded in step 2.
6. A popup window will appear asking you to confirm that you want to install the extension. Click Yes.
7. If you are using Windows Vista or Windows 7, you may need to allow SketchUp to make changes to your system when prompted.
8. Click OK in the popup telling you the plugin has been installed. Confirm that the checkbox next to the STL Import/Export plugin is checked, then click OK to close the preferences window.
If you're looking for models to experiment, look no further than SketchUp's 3D Warehouse: open the File menu, then 3D Warehouse, and select Get Models. To export a model as an STL file in SketchUp:
1. Activate the Select tool by clicking the pointer icon on the toolbar or by opening the Tools menu and clicking Select.
2. Click on the model in the scene you want to export. A blue box will appear around it.
3. Open the File menu and choose Export STL.
4. Name the exported file and click Save.
5. A popup will appear telling you how many faces and lines have been exported. This lets you know that the export process has finished.
You now have an STL file you can use with the RVW Model Importer. Check out the Model Importer overview video for directions:
At this time, there is a limit to the complexity of models that RVW can use. If when importing you get a message that says "Mesh could not be reduced enough to be compatible with RVW," you'll have to make a simpler version.

This summer students have the opportunity to learn how to program robots, design games, animate stories, and earn a chance to win over $10,000 in prizes and scholarships! The Robotics Summer of Learning program hopes to effectively increase students’ interest in STEM (science, technology, engineering, mathematics) related fields. The program is hosted online at the Computer Science Student Network.
The Summer of Learning initiative is sponsored by Carnegie Mellon’s Robotics Academy - an educational outreach of Carnegie Mellon University and a part of the university’s world-renowned Robotics Institute. The Robotics Academy mission is to develop educational tools and resources to use the motivational effects of robotics to excite students and teachers about science and technology.
The Computer Science Student Network (CS2N) is a collaborative research project between Carnegie Mellon University (including the Robotics Academy) and the Defense Advanced Research Projects Agency (DARPA) designed to increase the number of students pursuing advanced Computer Science and STEM degrees. CS2N is an online network for students and teachers to connect together and use engaging activities designed to teach how to program robots, animations, web pages, and games.
CS2N also includes tools for teachers/educators to create their own individual groups for students to join. Using the “groups” feature, teachers can track their students’ progress through every activity offered on the site. All of CS2N’s learning activities are designed to align with national educational standards.
Check out all the great features and challenges that will be offered through the Robotics Summer of Learning…
The Robotics Summer of Learning will offer students the opportunity to program a variety of robots in deep space, on a tropical island, and a VEX or FTC game board. The robots are programmed in ROBOTC, a programming language for LEGO, VEX and Arduino robots. Beginning ROBOTC users are able to utilize simple Natural Language commands like forward, reverse, and pointTurn at the introductory level and then migrate to full C-Programming to learn advanced computer science concepts like recursion, pointers, multitasking/threading, and multi-agent communications.
Students will program the virtual robots using the ROBOTC language and ROBOTC’s Robot Virtual Worlds (RVW) software, an interactive educational video game software that allows every student to experience the same benefits of learning robotics and programming. RVW tracks and stores student’s progress, through CS2N, as they solve different levels in each World. After successfully completing a World, students earn a badge that documents their achievements. At the end of the summer, students will have the opportunity to take an exam that will earn them a Carnegie Mellon Robotics Academy programming certification, which can be included in the student’s academic portfolio.
Introductory programming lessons are taught in the tropical themed Palm Island, one of three virtual environments in Robot Virtual Worlds. Once students learn the basics in their first mission, they are then challenged to complete missions on Planet H99 in deep space, and underwater in the Ruins of Atlantis. The final challenge is a national robot programming competition that will include over ten thousand dollars in scholarships and prizes. Two new “programming only” robotics game have been developed specifically for the Robotics Summer of Learning programming competition, which take advantage of current VEX and FTC games in Robot Virtual Worlds. The games are played by autonomously programming your robot to place objects into scoring positions as quickly as possible.
Animation programming languages, such as Scratch and Alice, make it easy for students to create video stories, animations, games, music, and art. By using storytelling and animation as a motivator, students learn the importance of the design process while using and learning interactive programming software.
Our Robotics Summer of Learning Animation Challenge is called Nature Doc-u-mentary. This challenge asks students to write a creative narrative and make an animated documentary using either Scratch, SAM Animation, or Alice 2.0.
Designing a digital game allows students the opportunity to creatively brainstorm ideas, create 3D objects to import into the game board, learn how to program in order to test the success of the game, and challenge them to think of ways to advance and optimize the gameplay. Robot Virtual Worlds comes with two great tools, the Level Builder and the Model Importer. The Level Builder uses a 12-inch by 12-inch board and our “desktop” models to create their very own Robot Virtual World. The Model Importer allows students to import their own 3D models into Level Builder to take their game to the next level. Students can use both tools while designing their own game board for a virtual robot to successfully complete!
Our Robotics Summer of Learning Animation Challenge is called Beacons and Barriers. This challenge will have users focus on creating levels for a virtual robot to navigate through. They will use the Model Importer, included in Robot Virtual Worlds, to create objects to serve as checkpoints and obstacles.
The Robotics Summer of Learning Program is excited for the opportunity to advance students’ interests in STEM and advanced their programming skillsets! Software and training will be provided for free throughout the summer. Students will have 24/7 access to the online course materials, as well as professional support from developers of the software and curriculum. There will be over $10,000 in prizes available to participants in the challenges, including free software, robot kits, and college scholarships. The Robotics Summer of Learning kicks off on June 1 and runs to September 1, 2013.
Also offered during the summer are our Professional Development courses. These courses provide teachers and coaches with a solid foundation for robot programming in the respective languages, and experience in troubleshooting common student mistakes. It also focuses on identifying and extracting academic value from the naturally occurring STEM situations encountered in robotics explorations. Classes are available on-site or online.
During Teacher Appreciation Week, we challenged students to send us stories about their awesome robotics teachers, mentors, and coaches. We received some great stories and are excited to announce the top three stories!! Each teacher will receive a 365-day classroom license for Robot Virtual Worlds. Below are the list of winners and the stories submitted by the students.
You think you’ve seen awesome but you haven’t met Miss Liberty! In 2009 she convinced our elementary school principal to let her start a robotics class. At first, she volunteered her time to teach 24 of us after school (we were in 3rd and 4th grade)…it was so much fun! She made learning how to program seem really easy. We used both NXT-G and ROBOTC.
Then, she loved doing it so much, she founded a STEM non-profit to start robotics and engineering programs throughout our community. She gave a ton of her time to help start robotics programs at elementary, middle, and high schools and then her “robot fever” spread to the neighboring school districts. She began teaching at multiple schools, starting FIRST teams at all levels, and helping us realize there was more we could do with our future then we ever thought possible.
In our community, because of her passion, we now have three school districts with: 4 high schools with actual engineering and robotics elective classes, 3 middle schools with engineering/robotics electives, and two elementary schools with technology rotations of programming with robotics. To top if off, she recruited other awesome teachers to help with the after school programs and every year there are over 32 schools who have full-time robotics teams…all because she rocks. (oh…and she helped the Palm Springs Air Museum raise over $400,000 to build a technology center for kids who want to do robotics, but it isn’t offered at their school!).
Well, we aren’t in elementary school anymore, but she continues to open up her house for our rag-tag group in addition to all the classes she teaches. We love her so much. She is enthusiastic about making sure we “learn how to learn”; thinking critically about everything we work on, from strategy, to psuedocoding, to prototyping out designs. She always answers our questions with questions, and has a neat way of helping us break down complex issues into tiny bite-size pieces.
But best of all, she encourages us to be “Fruitloops in a World Full of Cheerios” and challenges us to the best of who we can be and embrace our quirkiness.
Yeah…Miss Liberty is awesome!!!!!

“We know what we are, but not what we may be.” – Hamlet Act IV Scene V
A life beyond what we can perceive is a tall tale to tell indeed. The future is uncertain, opaque, and daunting. We can never truly grasp what it entails, and it often seems unreachable. Yet visions and plans of a future that we may influence lie entirely in our hands, and these dreams may be brought to reality through the wisdom, guidance and eccentric nature of one great man. Mr Graham Conlon is truly a delight to all. His enthusiasm, insight, good-humour and remarkable wit has propelled our team onwards and upwards to unimaginable renown. Whilst this may be marked as pretentious, there are no delusions of grandeur here. Mr Conlon has been a wonderful and exemplary mentor, showing us that with careful organisation, a calm approach, and a dry joke or two, we can affect and shape a collective future for the team. Regardless of the final outcome, we are taught that the journey that we embark on as a team is far more significant; That growing and developing as a team has more value than success. He centers our main focus around building an exceptional team that can then build, control and influence an exceptional robot. From there, the rest is our own doing.
Mentor from Reseda Regents Robotics
*We have not got official word from this coach to use his name in the article, so it has been removed from the story.
I do not write to you today about a mentor of my team, at least not a formal mentor. Instead I write of VRC#20 mentor. I recall him asking why I “wasn’t smiling” very much during the 2011 world championships as he handed me a completed score sheet with a win for red alliance. I find it strange; that single comment brightened the rest of the competition for me (even though I wasn’t sad, just tired) and forever made me a bit appreciative of what he does for robotics. Each year, my team (VRC#599) hosts a VEX tournament for teams in our area that services around 40 teams each year. As such a large event, we draw volunteers from numerous sources and rely heavily on volunteer support. Amongst the volunteers stand STEM teachers, college teachers, students, engineers, and parents. At my very first event, I knew the volunteers from my team and no one else. Within a year I recognized each face and knew each volunteer by name. I see the Reseda Regents Robotics mentor in the morning donning the bright Reseda Regents blue. Just as soon as his team is registered, the Reseda Regents Robotics mentor has put on the striped referee shirt. At every event, he does the same. You see him in bright blue, you see him in black and white. One would expect his black and white referee uniform to juxtapose his Reseda shirt just as the black juxtaposes the white. One would expect an on/off relationship of volunteer to coach; a relationship that leads him to coach his team and volunteer as two separate entities. His Reseda blue very well may be the black and white of the Referee shirt or the gray of a volunteer shirt. In everything he does, he presents a team that inspires. Reseda blue stands out amongst the field reset crew. Reseda blue stands out amongst the queueing team. Reseda blue stands out amongst the half assembled fields. Reseda blue stands out amongst my Robodox green. Reseda blue stands out because team 20, Reseda Regents Robotics, and everyone else emulate an outstanding mentor and teacher whose Reseda blue stands out amongst everything he does.

Thank you to every one who sent in their stories and thank you to ALL teachers, mentors, and coach for everything you do for your students!
I’d like to welcome a new section to our blog called Teacher’s POV (Point of View) that will allow guest bloggers who are teachers, mentors, and coaches to share some of the lessons they have learned while teaching robotics. Our first guest blogger is a good friend to the ROBOTC family, Jason McKenna, a K-8 Gifted Support Teacher in the Hopewell Area School District outside of Pittsburgh, PA. He has been kind enough to put together some blogs about his experiences teaching robotics.
As teachers, we are constantly looking for ways to make the subjects that we are teaching relevant. Students are always asking when they will ever use a particular concept, or how what they are learning applies to a real life scenario. Admittedly, teachers sometimes have a hard time answering those questions.
Thankfully, teaching Robotics and computer programming puts those questions to rest. Because technology is so ubiquitous in students’ lives, students will immediately see the benefits of learning how to program. Moreover, Robotics is the perfect platform to show the application of math and science concepts to everyday scenarios.
In addition to all of that stuff that we educators like to talk about, students just have fun programming a robot to do something. Add in the allure of some competition, and you have yourself a pretty engaged classroom.
With that in mind, I decided to have my 8th grade students participate in a line following car race. Students were to program their robots to follow a line as fast as possible. Of course, the trick is the robot has to stay on the line. While following a black line, the robot has to decide (using a light sensor) if it is on the black line or on the white part of the mat. For the competition, the students added some PID concepts to their line following. As many of you already know, PID is used in many control systems, from your car, to your homes, to large scale factories. The students and I discussed how PID is basically a control system that tries to calculate an error and make adjustments to a control system based upon that error. The robot calculates an error (how far it is off the black line) and then makes adjustments to the motor speed based upon the error. That is what makes it proportional: the movement is based upon the error. Large error equals a large correction whereas a smaller error creates a smaller correction.
The students were able to apply some of the concepts they are currently learning in Algebra to their program. For example, they are utilizing the slope intercept formula (y=mx+b) to find their turn. Y is the turn distance, x is the light sensor reading (the error), and m is the change in y (maximum and minimum turning power) divided by the change in x (maximum and minimum light sensor reading). Students get to apply an important math concept to a fun and engaging scenario that has real-world applications.
The students then decided that they wanted to see what would happen with two light sensors. The students adjusted their code, conducted some iterative testing, and surveyed their results.
In conclusion, one really sees how Robotics and ROBOTC meld perfectly with the goals of a STEM classroom. Really, the only limitation is a teacher’s (and students’) imagination.

In preparation for the 2013 Robotics Summer of Learning, we’ve released updates for the Palm Island (v2.1.0), Operation Reset (v3.1.0),Curriculum Companion (v2.4.0), and Level Builder (v2.0.11) Virtual Worlds!
In Palm Island, Operation Reset, and the Curriculum Companion, we’ve added two highly-requested features: Graphics Quality Control andUpdate Notifications.
Graphics Quality Control
In the Options section of each virtual world, we’ve added a new Graphics Quality setting. Choosing LOW (FASTER) will reduce the visual quality of the virtual environment, but will allow the virtual worlds to run more smoothly on older computers. MEDIUM is the default setting and is a balanced choice between quality and speed on most computers. Choosing HIGH (SLOWER) will improve the visual quality and is the most resource intensive; it is only recommended if you have a newer computer with a dedicated graphics card.
If your computer is connected to the Internet and you log in using your CS2N account in the virtual world, it will now check if there is a newer version of the virtual world available. If an update is available, a notification about the new version appears with a DOWNLOAD NOW button. Simply press it to download the latest version available!
RVW Level Builder
We also updated the RVW Level Builder! We have improved the performance of the menus and fixed an issue where line tracking tiles were getting “stuck” once they were placed. Thank you to everyone who has sent in feedback! We’ve also released a series of videos to help get started with the Level Builder:
The updates can be downloaded from the RVW Level Packs Download area at ROBOTC.net or RobotVirtualWorlds.com.
We recently added a great new feature to our Robot Virtual Worlds … the Measurement Toolkit! There is no more guessing on how far a robot needs to travel to solve programming problems. It allows for intelligent path planning and navigation. You can now have students do the math, show their work, and explain how they solved the problems.
Check out our newest video that talks about what the measurement toolkit can do in RVW!
