Once the physical hardware (robotics kits) are secured for a classroom, the next step is to install the software (ROBOTC and Robot Virtual Worlds). It would be nearly impossible to cover every single specific setup that could be encountered on a classroom’s computers, but this blog post will cover the basic installation steps and some of the more common installation issues that educators may run into when installing ROBOTC in a classroom.
The first thing you will need to do is install ROBOTC on the computers in your classroom. To do this, always make sure to grab the latest version of ROBOTC that your license supports from the correct ROBOTC download page. If the wrong version is downloaded and installed, or if there is already a different up-to-date version of ROBOTC installed on the computers, you will not need to uninstall and reinstall the program; instead, you will simply need to activate your license in ROBOTC (more on this later). During the download process, ROBOTC will also attempt to install the necessary drivers for communications with physical robots. Depending on the level of security on the computers, you may need to get your IT department involved in order to ensure that the drivers are installed properly.
Once ROBOTC and the appropriate drivers have been installed, you will need to activate ROBOTC on each computer manually. The license activation ‘unlocks’ the ability to download code to either a physical robot or a Virtual World, depending on which license is used. When ROBOTC is installed on a computer, all versions of ROBOTC (including different robotics platforms, such as the VEX and LEGO platforms, and different compiler options, such as Virtual Worlds compiler options) are installed at the same time. Instead of installing additional copies of the software on the same computer (or opening a new program every time you would like to change the compiler target), the additional platforms and compiler options are ‘unlocked’ by activating their respective keys.
Before we move on to the next blog (Setting up the Robots), here a couple more tips that may come in handy when setting up ROBOTC in a classroom:
- Depending on the programs, policies, and restrictions in place on the machines, your school’s IT department may need to be present for the installation or activation of ROBOTC, Virtual Worlds, or the installation of any drivers for the physical robots.
- If your school’s IT department images and deploys the classroom’s computers, make sure they reference the ROBOTC Deployment Guide on the ROBOTC wiki for important help and information.
- Make sure to check the computers’ hardware to the minimum requirements for ROBOTC or Robot Virtual Worlds before
- Always test one computer first! If there is a problem with the installation, it is better to find out about it early and fix it before they same issue appears on a classroom full of computers.

There is a bevy of materials to help a teacher get started teaching the ROBOTC Curriculum. But what about the teacher that has made it through the curriculum and has a robotics class returning at the beginning of the school year? Whether that teacher is preparing to enter a robotics competition or is planning on creating a cool ROBOTC project, the teacher will still need to determine what the students have retained from the previous year.
Students that have made it through the ROBOTC curriculum should be able to use variables and functions in their programs. A great way to assess this would be to utilize the Robot Virtual Worlds. Students can spend the first week of school trying complete all of the missions within Operation Reset. Working with Operation Reset affords teachers the opportunity to differentiate this beginning diagnostic. Students that have retained more information can work independently, while those students that need more assistance can get the help they need. This is just another great application of Robot Virtual Worlds in the robotics classroom.
If Robot Virtual Worlds is not an option, you can apply the same concept with a physical robot. For students that are already proficient with ROBOTC, a good challenge to begin the year with would be the Chasm Detection.
Another great tool that a teacher can utilize is the debugging of code. This can serve as a good one or two day review of ROBOTC syntax and logic. If a teacher is anxious to get started with a project and wants a quick review, this may be the way to go. One of the nice things about using code is the teacher can get some quick and individual feedback from the students. If time allows, a teacher may use one or two examples of code, see where the students are, and then design a challenge for them. Here is an example of code that the students could troubleshoot.
Hopefully this gives you some ideas of how you can reintroduce ROBOTC to your students. A seamless beginning to the school year will help with all of the projects and activities that you may have planned for the rest of the school year.

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.

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.
