The robot marathon has started! As the large autonomous vehicle drives down the empty street, it decides when and where to turn. The bot navigates through the streets, using the dashed lines as guides. There are a lot of potential wrong turns that it avoids as it rolls by houses and picnic tables. Eventually, it drives under the banner at the finish line much to the programmer’s delight.
Did this happen in your town? Maybe! In fact it might be happening in your town right now because it’s not a physical robot – but a virtual robot driving through a virtual town!
This is a game level created by Robotics Academy high school intern, Eddie, for the Beacons and Barriers level design competition. Eddie used Autodesk Inventor to create some of the models and imported them into the Robot Virtual Worlds Level Builder.
The competition asks participants to create a level for RVW Level Builder, including Checkpoints and obstacles, through which players will navigate a robot. In addition, participants must write instructions for the level.
How He Created the Level
Eddie used the design process discussed in the Computer Science Student Network’s (CS2N) course for level design called Create Your Own Level with RVW Level Builder.
This process starts with brainstorming and research. He jotted his notes on a piece of paper. You’ll notice in the image that the drawings are not perfect, that some things were crossed out. That’s perfectly fine – in fact – that’s what you want to do.
The process of jotting your ideas on paper allows you to see ideas. If they aren’t good or they won’t work like you thought they might, then you can modify them or come up with ones that will work. Notice how Eddie crossed out the first drawing with the curved road? He realized that roads might be easier to construct if they were straight.
Eddie then mapped out his level – showing the start tile, finish tile, checkpoints, and obstacles (in this case: grass). He then drew how the tiles should look. Afterward, he modeled the tiles using Autodesk Inventor. The Inventor Tutorials course on CS2N was helpful in showing him, step by step, how to create an object, export it and then import it into RVW Level Builder.
Once he made his level, Eddie tested it and wrote down ideas for ways to test it. He then gave the level to a peer to test. The test results proved that the level worked well and wasn’t too hard.
For the last phase, Eddie wrote the instructions for the level, zipped the level and the instructions into the same folder and submitted it to the competition.
How You Can Create Your Own Level
This was Eddie’s first time using the RVW Level Builder and he has had limited experience using Autodesk Inventor. He learned how to use these programs by enrolling in free courses at www.cs2n.org. You can too! And since they are online, you can learn at your own pace
Check out the courses:
Introduction to Inventor – Learn the basics of Inventor.
Create Your Own Level with RVW Level Builder – From ideation to product release, learn how to create levels using the RVW Level Builder.
Inventor Tutorials – Step by step instructions on creating an object in inventor and importing it into RVW Level Builder.
Once your level is complete, upload it to one of our level design competitions on CS2N.

I took Grow a Generation to a recent Zumbathon fundraiser for the Yellow Ribbon Girls. Several kids meandered over to the table while the moms were working out. I invited them to play around with the Scratch programming window that was opened on the computer. One girl, I think about 10 or 11, became enamored with Scratch, asking how to make the cat she choose as a sprite move around the screen. I showed her a few command codes and encouraged her to experiment. Intent, she focused as hard on that screen as the 200+ moms focused on their workout. When the workout was over, her mom, exhausted and drenched, came to grab her hand and walk off. It took several attempts by me to convince the mom to actually look, and several more attempts to explain the daughter had not been playing a game, rather programming a new one. She had programmed her cat to dance a Zumba workout. Even then, the mom didn’t seem to understand and finally looked closer to let her child explain the code she had put in place. The mom was incredulous, “You mean my daughter actually programmed this?”
I spent this week working with some brilliant young people as they were introduced to Alice 2, a free drag and drop educational programming language that allows students to create computer animations using 3D models. Our theme was Zany Animals and each student was tasked with inventing a creature and animating it with special qualities. J.K. Rowlings inventive imagination supplied fuel for our creativity while we looked at the etymology and origins of some great Harry Potter creatures (Basilisk, Phoenix, Hippogriff, Boggart, and Thestrals). The Discovery channel demonstrated some very real incredible animals and provided a template for our short nature documentaries. We discussed the ethics of animal experimentation and watch some videos of the current status on cloning, using animal to create pharmaceuticals and synthetic proteins, and grafting technology onto animals.
One of the uncles (a young man in his late twenties) stopped mid-week and looked around at the fun we were having. He shared his remembrances of computer science class in high school, a black screen with detailed code he could not make work. He had walked away from high school convinced Programming was something he could not learn.
His comments, alongside the mom’s at the Zumbathon, have me wondering about marketing. Only five students enrolled in the camp. While other factors played a part, how do I advertise to a generation who cannot conceive a child can begin to write code (and have fun doing it)? How can we work to allow not just the technology teacher and the media lab director, but also the classroom teacher encourage computer programming and the creation of digital artifacts in the creative expression of their students.
I have had to journey my own learning curve this summer. I am taking the CS2N Summer of Learning class in ROBOTC. The Alice 2 tutorials I did in class were adapted from the CS2N Introduction to Alice class that is available free on their website. I learned alongside the kids and eagerly accepted the wonderful help of two area middle school STEM heroes who run their own programming classes in the homeschool network – Fiona and Joseph Chaney.
The camp was such fun. The kids learned to select an environment and create an establishing shot for their animals habitat. They then created their creature by selecting the object of an animal and changing colors, textures, ear size, nose size, arm length, etc. They started animating their animal to demonstrate its incredible abilities and changing camera angles to tell a story. Finally, they added sound and narration to their animation. All of this was done while learning basic computer care, where to save and recover files, and how to deal with constant messaging of “Alice thinks you made an error” and carry on through frustration. The kids will be using the animations they created to enter the CS2N Nature Doc-u-mentary competition.
Two learning leap moments stood out. The first was a child who had originally placed two dragons into the scene and they create a ‘method’ called fight. He dragged the method into the editor box and couldn’t figure out why they weren’t fighting. He had not yet connected the need to write the script for each movement of each dragon to create the method. The rest of his week was spent focused on getting a dragon to flap his wings. It tied in beautifully with a video on the last day about how computer animation team created the Thestral flight scene in the Harry Potter Order of the Phoenix movie. This boy was breaking down the abstract concepts of ‘fight’ and ‘fly’ and beginning to think in terms of modeling, algorithms, and sequence.
Another moment came when a student wanted to have a turtle disappear into his shell. I found a brief tutorial online (the Alice tutorials are out there, but they are not as easy to find as the Scratch tutorials) and he was able to follow it. When I checked back in to examine his code, I was so impressed how he could walk me through the control structures he put in place for sequence, conditions, and parallel execution!
High points included sitting outside on a gorgeous rain free day in the shade under the tree at a picnic table at Baden Academy as students typed away on their netbooks creating their animals, inspired by the new surroundings and summer breeze. Another was the look of such pride as parents and grandparents applauded to see the student creations on the screen in the lab at the end of the week.
Embarrassment of the week – despite a Ph.D., I could not visualize the need to invert the image on the iron on for the shirts – so if you see a smiling child wearing a shirt with a picture of their Zany Animal and all the text is backwards, know that you are looking yet another erratum of Dr. Ellen.
I close with a recent Facebook post from a mom: “John made this video in his computer class this past week. It is short but he has never done anything like this in the past. Wish the class was longer than five days. He loved it.”
Enjoy the kids work – and don’t forget to add your comments!
FireBall the Devious Hamster Crook
Ray McNamara is relatively new to ROBOTC, having only really started to seriously use it within the past year, but already he’s come up with some interesting projects that caught our eye. The “Monster Ball Sorting Factory”, which he shared with us on the forum, is definitely a cool project we had to share.
The Factory is a cooperation between two robots Ray’s designed. One is an NXT Forklift truck, which uses a special non-standard part: a pair of Omni Wheels in the back to replace the standard single rotating wheel, which makes the Forklift’s turns a lot more reliable.
The other is a long, conveyor belt and claw arm robot that sorts balls piled onto a conveyor belt based on their color. It then puts them into containers, which the Forklift periodically takes and places in a slot so that the robot can dump it into a bigger bin. This robot is a combination of an earlier project, the “Bin Emptying Machine,” that takes the balls out of their container with a rail mounted crane that does the sorting.
We asked Ray about the project and his motivation for doing it and he replied:
“My Monster Sorter is still a work in progress, much to my wife’s annoyance due to the amount of real-estate it has been taking up in the lounge room since early December 2012. I hope to have it all running on a single NXT (excluding the Forklift), by means of 2x Mindsensors Motor Multiplexers and 1x Mindsensors Sensor Multiplexer. If my calculations are right, the single NXT Brick will control 8x Motors and 10x Sensors.
My motivation was the challenge to learn how far I take the standard Colour Sorter model. It really started back in 2010, when I convinced Rotacaster Australia‘s GM to turn his industrial rollers into Omni-wheels for my LEGO Models and robots. After almost exhausting the possibilities of Holonomic Platforms, I looked into other uses for the Rotacaster Wheels, resulting in my Forklift Truck.
Once I had my Forklift Truck, I needed to put it to work. The Ball Sorting Factory was what evolved over a few days. Since then I have been fine tuning the hardware and the ROBOTC code used to control it. In the process, I have also been Beta Testing some Mindsensors Sensors and Multiplexers with it.
I always try to include a detailed description, photos, video, code and CAD files for my robots when they are published to my blog. Although it takes a lot of time to put my blog posts together, I feel it is worth it. I get a lot questions and praise from many people who use my resources. I especially enjoy helping out students with their queries.”
Thanks to Ray for taking the time to respond to our questions! Visit Ray’s website at www.rjmcnamara.com to see more projects, pictures, codes, videos, and much more.

We interviewed Kjersti Chippindale and Violet Replicon, who are the mentors for the FIRST Tech Team 6002 – The Basilisks, and asked them to tell us about their FTC robotics experience. They used to be members of FTC Team Antipodes, but decided that they’d rather spend their Senior year mentoring two brand new teams in hopes to keep the robotics tradition alive at their school.
