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.
The 2013 Robotics Institute‘s LEGO IC Challenge involved programming with ROBOTC! This year’s challenge was based on a standard mini-golf course. Each team needed to build a robot using the Lego NXT and program in ROBOTC to traverse a moving platform, ford a “sand” trap (or go around), and duck through a spinning windmill.
The challenge is part of the Robotics Institute’s Robotics Immigration Course, which all Robotics students must attend at the beginning of their first semester in the program. The course is a series of lectures, discussions, and demonstrations that familiarize the students with Carnegie Mellon and the Robotics Program, introducing them to the research projects and faculty within the Program and affiliated departments, and describe the computational and other resources available in the Program. The Robotics Immigration Course gives the students an opportunity to learn what it means to conduct research and to get to know the faculty in the Robotics Program.
Congrats to Neil Abcouwer, Hugo Ponte, Erik Nelson, and Nicholas Gisolfi, who came in first place at the challenge!
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.
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 kit, LEGO MINDSTORMS EV3. This article will help break down LEGO’s kits, 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 LEGO MINDSTORMS EV3 is the all-new robotics kit from LEGO Education (creators of the LEGO MINDSTORMS NXT system). It is fully compatible with previous NXT hardware (except for the battery), including all plastic structural pieces and sensors.
- Compatibility with the MATRIX and TETRIX metal systems is expected in fall 2013.
- Those starting a classroom from scratch need not worry; the EV3 comes with a total of 541 elements, including a multitude of structural parts (beams, connectors, wheels, gears, etc), 4 different sensor types (color sensor, gyroscopic sensor, ultrasonic sensor, and touch sensor), 3 motors, and the EV3 micocontroller or ‘brain’.
- The EV3 microcontroller sports 4 sensor ports, 4 motor ports, a internal Bluetooth adapter, and a USB slot which can be used with a WiFi adapter for wireless connectivity (as well as microSDHC card slot which supports cards up to 32GB in size).
- It utilizes a Linux-based firmware which allows for on-brick programming and datalogging.
- The EV3 will be legal in the 2013 First Lego League (ages 9-14) and the 2014-2015 First Tech Challenge (High School) competitions.
- Recommended use: Middle School (EV3) or High School (with MATRIX or TETRIX kit).
Now, let’s take a look at the LEGO MINDSTORMS NXT V2.0. Released in 2009, the NXT platform utilizes a plastic snap-fit hardware structure system, with 431 elements included in the base kit.
- These elements consist of both structural pieces (beams, connectors, and axles, to name a few), three interactive servo motors, the NXT microcontroller, and ultrasonic, light, sound, and two touch sensors included.
- There are also many third-party sensors available from sites such as Hitechnic, Dexter Industries, and Mindsensors.
- The NXT is also fully compatible with the MATRIX and TETRIX metal systems.
- Wireless capabilities include built-in Bluetooth and WiFi connectivity (provided by an external Samantha Module adapter).
- The NXT is currently a legal microcontroller for both the First Lego League (FLL, ages 9-14) and First Tech Challenge (High School) challenges.
- Recommended use: Middle School or High School (with MATRIX or TETRIX metal kit).
We understand that choosing a robotics kit is a tough decision. The number one factor in determining which kit is right for you will come down to the students; depending on the skill level of the students, it may be better to challenge them with a more advanced kit (MATRIX or TETRIX kits) or they made need to start with a simpler kit (LEGO NXT or EV3 kits). No matter which kit you decide to use, though, you can rest easy knowing ROBOTC will fully support all of these platforms.

Tarek Abdelwareth, an undergraduate studying Computer Engineering at Nile University in Egypt, shared with us a very cool ROBOTC project he put together with his team called Human Vs. Robot: Tic Tac Toe Challenge.
The robot was designed using only LEGO MINDSTORM parts and a white board pen then programmed in ROBOTC with more than 1500 lines of code. We asked Tarek to share some information about the robot …
“It took me and my team about a week to build the design and a month to complete the code of all programming stages we set. We participated in the WRO (World Robotics Olympiad) with this robot in the Open Category (Senior-High) last year. Our team got the first place in Egypt and the 10th place worldwide.
The robot in the video is actually an old version by the way; there has been much improvements in the programming that made it faster and efficient. Plus, the algorithm of thinking and playing has improved that the robot simply never lose now.”
We had the chance to interview the lead programmer for FTC Team 5037, Kristen McKellar. She is an impressive programmer with a bright future ahead. Check out her story on how her knowledge of ROBOTC helped her win the National 4-H Engineering Challenge …
