Which Robotics Kit Should I Use? VEX Edition

without comments

VEXiq-109Now 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.

cortex-robotOne 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.

Which Robotics Kit Should I Use? LEGO Edition

without comments

EV3-Cutout-01-copyNow 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).

Other-BUG-Robots

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.
