Getting your classroom organized for the beginning of the school year is an arduous task for even the most experienced teacher. It can be even more demanding for those that teach robotics. You’ve got the robot kits, you’ve been trained in ROBOTC, but how do you set up your class for the first day of school? The goal of this article is to help answer the question for both new robotic teachers and teachers that have been teaching robotics for years.
As we all know, a robotics kit is more expensive than a textbook. Moreover, because robotics kits contain so many small pieces, they can be much more difficult to take care of than a textbook. As a result, keeping your kits organized is crucial. If using a LEGO MINDSTORM NXT, EV3, or TETRIX robot, one way that I have found that can be very helpful is to name the NXT brick. Then, give the same name to the kit. Now, assign the kit to the group of students in your class. If the students know that they are responsible for that kit, it goes a long way towards them acting more responsibly with the kit. If using a VEX robot, you won’t have the same ability to name your brick, but you can still able to label your robotics kit.
Which students are assigned to work together is also something that the teacher must put some thought into. Once again, maintaining the kits is of the utmost importance. Therefore, I am not going to allow students to work together if I feel that will not take care of the kit. Some students are more organized and careful with the kits than others. I always try to have one of those students in a group. I try to have the kits named and assigned before the first day of school. If I don’t know the students, then I may have to adjust the groups as we progress throughout the beginning of the school year.
Once the kits are organized, the teacher can then start to think about how their curriculum items are going to be accessed and utilized. A math teacher has a plan for when their students have a question about a topic, or when a student is confused about a particular concept. A robotics teacher has to have the same type of plan in mind. The beauty of teaching robotics lies in the fact that students are intrinsically motivated to find answers to their problems because they are highly engaged. Some students will still be conditioned, however, to try to elicit the answer from the teacher instead of reasoning through a problem on their own. Robotics teachers need to create a plan so the students can work towards being independent and productive problem solvers.
To that end, a good approach to a complex challenge is to examine what needs to be done before the challenge, during the challenge, and after the challenge is complete. Before the challenge, students should be focusing on create flowcharts to organize their program and writing pseudocode to reflect those flowcharts. During the challenge, students should focus on commenting their code and debugging techniques. Afterwards, students should be afforded the opportunity to reflect and respond to what went well, what went not so well, and what they learned throughout the process.
Giving students a little bit of structure while they engage a challenging task will go a long way towards ensuring that the students’ high level of engagement does not turn into a high level of frustration. Engagement works both ways in that sense: High engagement leads to students that are focused on their task, but can also lead to high levels of frustration because the students desperately want to finish that task. To avoid the frustration,teachers should provide a structure that the students can rely on when needed. Before the school year begins, teachers should spend some time planning students’ work, and then the students can spend time during school working their plan.
The beginning of the school year is always a challenge. As teachers, we understand that unforeseen difficulties will always arise. However, going into the school year with as much planned and organized as possible helps us to focus on those unpredictable events that will undoubtedly occur.
Check out how we organize robot parts at the Carnegie Mellon Robotics Academy:
It is that time of year again … backpacks on our backs, buses on the streets, and lessons being planned. Yes, we are going back to school! To kick start the school year, we are introducing a six week robotics back to school blog series that highlights the technical and pedagogical side of planning for your robotics classroom. John Watson, from ROBOTC customer support, and Jason McKenna, a K-8 Gifted Support Teacher in the Hopewell Area School District outside of Pittsburgh, PA, will be sharing with you tips, tricks, advice, and recommendations on prepping your robotics classroom and curriculum.

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.”

In years past, the science and art fields were generally considered to be diametrically opposed; if something was scientific it usually didn’t have artistic value, and if it was a work of art it probably didn’t do much for the scientific community. Recently, though, the line between art and science has been blurred and blended in some very unique and interesting ways.
A prime example of this is a color-sensing “Coltar” made by Youtube user PhilippLens. By mixing imagination with ingenuity, PhilippLens created the hybrid guitar using a LEGO Mindstorms NXT brick with a color sensor and two touch sensors (one on the Coltar itself, the other on the ‘pick’). Using the touch sensors to control chords and the color sensor to control which notes are being ‘strummed’ allows the Coltar to emit a surprisingly large range of notes.
