Now that the physical robot kits are in the classroom and ROBOTC is installed and activated, you should be ready to build the physical robots for your classroom. One of the best features of a VEX Robotics kit is that they allow students to create a nearly limitless range of robots; the downside of this, however, is maintaining student-created robots in a classroom. To help with this, ROBOTC and the Video Trainer Curriculum support several standard models to help keep a baseline in the classroom.
The first of such robots we will look at is the VEX Squarebot (using the VEX Cortex), one of the standard Cortex models that are used in the VEX Cortex Video Trainer for ROBOTC. The Squarebot utilizes three VEX motors (two for driving, one for the arm), and a wide variety of sensors. These sensors include Quadrature Shaft Encoders, a Sonar Sensor, and a Potentiometer (among others; in total, there are 8 separate sensors on the Squarebot). This model allows for a variety of tasks to be completed and is designed to work with all of the challenges in the ROBOTC Curriculum.
A smaller, different alternative Cortex standard robot is the Swervebot. Like the Squarebot, the Swervebot utilizes the VEX Cortex as its main processor and uses two VEX motors for driving. However, the Swervebot’s small chassis does not utilize an arm. Instead, the Swervebot makes clever use of an Omniwheel in the rear for turning and boasts three Line Follower sensors and a Gyroscope (as well as 6 other sensors, for a total of 10) and is perfect for smaller classroom environments.
Finally, the new VEX IQ platform can be quickly assembled and ready to use in a classroom thanks to the IQ Clawbot standard model. Using 4 motors total (two for driving, one for the arm movement, and one for gripper control), the VEX IQ Clawbot can be controlled either autonomously using the VEX IQ sensors (such as the Bumper Switch and Color Sensors), remotely using the IQ Controller, or a pleasant mix of both, depending on which kit is being used.

Now more than ever, robotics educators are faced with the important question of which kit they should purchase and use. This key question has been made even more intricate in the 2013-2014 school year due to the addition of the new robotics kits, VEX IQ kits. This article will help break down each VEX kit, their capabilities and target audiences, and allow you, the educator, to make an informed decision on which kit is best for your particular classroom.
The VEX IQ system is the brand-new robotics system from Innovation First International (IFI for short, makers of the VEX Robotics Design System). The VEX IQ can be used with any of the all-new hardware and sensors, including a unique plastic snap-fit structural system.
- Sensors include a gyroscope, color sensor, potentiometer, touch LED, and ultrasonic sensor.
- The base kits (either Sensor or Controller kits) are provided with over 650 structural components, 4 plug-and-play ‘smart motors’, at least 2 touch sensors (or more, depending on kit), and the VEX IQ microcontroller (more information on all available kits can be found here).
- The IQ contains 12 smart ports that can be used to control either analog sensors, digital sensors, or servos/motors; the ports are non-typed and can be used to control any piece of VEX IQ compatible hardware that is plugged into it.
- It also includes a micro-USB port for IQ-to-computer communication and a ‘tether’ port for direct connections to an VEX IQ Controller.
- Debugging and programming information can be displayed on the backlit LCD information to increase ease-of-use in real time.
- Wireless communication between the VEX IQ microcontroller and a VEX IQ controller is provided via a set of 900 MHz radio adapters.
- The VEX IQ system will be fully legal in the new VEX IQ Challenge (designed specifically for the VEX IQ system), for students ages 8-14.
- Recommended use: Middle School.
One of the mainstays of the educational robotics world is the VEX Cortex platform. Originally released in 2010 by IFI, the Cortex can be used with the VEX Robotics Design System’s hardware and sensors.
- Includes over 300 metal structural parts, 4 powerful DC motors, the VEX Cortex microcontroller, and a wide variety of fasteners, gears, and other miscellaneous hardware.
- Sensors include touch sensors, an ultrasonic sensor, integrated motor encoders, line following sensors, and a potentiometer; additional sensors are available outside of the base kits.
- Wireless communication between a VEX Cortex and a VEXNet Joystick Controller is possible by using the 802.11b/g VEXNet USB Adapter Keys.
- The VEX Cortex system can be used in the VEX Robotics Challenge (Middle, High School, and College divisions).
- Recommended use: advanced Middle School, High School or College.
We understand that choosing a robotics kit is a tough decision. The number one factor in determining which kit is right for you is the students; depending on the skill level of the students, it may be better to challenge them with a more advanced kit (VEX Cortex) or they made need to start with a simpler kit (VEX IQ.) No matter which kit you decide to use, though, you can rest easy knowing ROBOTC will fully support all of these platforms.
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 Mindstorms 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.

At the VEX World Championship in Anaheim, VEX introduced their newest robotics platform, VEX IQ. VEX IQ is designed to transform STEM learning for students and their teachers. Students as young as 8 can begin building and programming their robot.
In the VEX IQ Challenge, students, with guidance from their teachers and mentors, build a robot using the VEX IQ robotics platform to solve an engineering challenge that is presented in the form of a game. VEX IQ Challenge teams will work together scoring points in Teamwork Matches, and also get to show off their robot’s skills individually in driver controlled and autonomous Skills Challenges. VEX released a new video yesterday that explains the rules of the game.
There are a total of thirty-six (36) Small BuckyBalls and four (4) Large BuckyBalls available as Scoring Objects in the game. There are four (4) Floor Goals, two (2) Low Goals, two (2) High Goals, and four (4) Scoring Rings, as well as a Hanging Bar. Official game documents are available here: VEX Wiki – Add It Up
Registration for a VEX IQ Challenge team costs $100. Additional teams from the same schools can register for $50. Tournament entry fees vary by event. Visit RobotEvents.com for more information, to register a team and find events near you.
Here at ROBOTC, we are very excited to have the upcoming ROBOTC for VEX Robotics 4.0 support both VEX Cortex and VEX IQ. We feel that this will allow for an easy transition for students. Using the IQ system will let them learn the VEX eco-system and make the transition to full metal/larger robot even easier – plus since everything can be programmed with ROBOTC, there’s no new software learning curve. We were honored to announce this new addition to ROBOTC at the World Championship. Check out the video from our presentation:
Carnegie Mellon Robotics Academy is also developing new curriculum and trainings for the new VEX IQ platform and ROBOTC for VEX Robotics 4.0. Curriculum, software, and training will be available this Fall. To find out more information visit: Robotics Academy VEX IQ.
