Unterschiede zwischen VEX IQ 1st Generation und VEX IQ 2nd Generation
Die VEX IQ Plattform ist ein modulares Robotiksystem, das speziell für den Bildungsbereich entwickelt wurde. Seit der Einführung der 1st Generation im Jahr 2012 hat sich die Technologie erheblich weiterentwickelt, was zur Einführung der 2nd Generation führte. Mit der Einführung der 2. Generation von VEX IQ gibt es einige wesentliche Unterschiede und Verbesserungen im Vergleich zur 1. Generation. Dieser Artikel beleuchtet die wichtigsten Unterschiede zwischen diesen beiden Generationen.
Elektronik und Kompatibilität
Ein wesentlicher Unterschied zwischen den beiden Generationen liegt in der Elektronik. Die 2nd Generation umfasst modernisierte Elektronikkomponenten, die mit den älteren Komponenten der 1st Generation kompatibel sind. Dies bedeutet, dass Lehrer und Schüler, die bereits über 1st Generation Kits verfügen, problemlos auf die 2nd Generation aufrüsten können, ohne dass ihre bestehenden Komponenten unbrauchbar werden.
Ein vorteilhafter Unterschied ist die Einführung eines neuen Akkus in der 2nd Generation, der Lithium-Ionen-Zellen verwendet und eine erheblich längere Laufzeit bietet, ohne dass es zu einem Leistungsabfall kommt. Allerdings ist der neue Akku nicht mit dem Ladegerät der 1st Generation kompatibel, was beim Aufladen berücksichtigt werden muss. Dafür kann der Akku nun einfach per USB-C geladen werden ohne ein spezielles Ladegerät.
Sensoren und Motoren
Die 2nd Generation bietet verbesserte Sensoren, darunter einen neuen laserbasierten Distanzsensor, der einen sicheren Klasse-1-Laser verwendet, um präzisere Messungen zu ermöglichen. Der neue optische Sensor bietet eine bessere Leistung bei schlechten Lichtverhältnissen und kann sogar die Annhäherungsgeschwindigkeit messen.
Ein weiterer signifikanter Fortschritt ist der integrierte 3-Achsen-Gyroskop und 3-Achsen-Beschleunigungsmesser im Robot Brain der 2nd Generation, die eine genauere Positionsbestimmung ermöglichen. Im Gegensatz dazu verfügt die 1st Generation nur über ein 1-Achsen-Gyroskop.
Beide Generationen verfügen über leistungsstarke Smart-Motoren, jedoch hat die 2. Generation bereits mitgelieferte Omni-Wheels, die eine verbesserte Beweglichkeit des Roboters ermöglichen. Diese Räder erlauben es dem Roboter, sich in mehrere Richtungen zu bewegen, was die Manövrierfähigkeit erheblich steigert.
Programmiermöglichkeiten
Die 2nd Generation bringt erweiterte Programmiermöglichkeiten mit sich. Während die 1st Generation hauptsächlich mit ROBOTC programmiert wurde, nun aber auch zur neuen Software kompatibel ist, unterstützt die 2nd Generation komplett VEXcode, das Programmiersprachen wie Python, Blocks und C++ umfasst. Dies bietet eine größere Flexibilität und Anpassungsfähigkeit für verschiedene Bildungsniveaus und Lernziele.
Diese Software ist für verschiedene Plattformen wie Windows, macOS, iOS und Android verfügbar und ermöglicht einen einfachen Einstieg in die Programmierung. Die Möglichkeit, von einer grafischen zu einer textbasierten Programmieroberfläche zu wechseln, erleichtert den Übergang zu komplexeren Programmiersprachen.
Einfachere Programmübertragung: Die Programme können, über den Funk-Controller auf die Roboter übertragen werden. Bei Apple und Android-Systemen funktioniert die Datenübertragung auch direkt über Bluetooth.
Mechanische Komponenten und Bauoptionen
Die mechanischen Komponenten der 2nd Generation wurden ebenfalls verbessert. Die Kits enthalten neue und verbesserte Teile, die mehr Bauoptionen bieten und die Bauweise der Roboter erheblich verbessern. Diese Verbesserungen wurden in enger Zusammenarbeit mit MINT-Pädagogen entwickelt, um den Bildungswert zu maximieren.
Benutzerfreundlichkeit und Wartung
Ein weiterer Vorteil der 2nd Generation ist die vereinfachte Firmware-Aktualisierung. Die neuen Robot Brains können automatische Firmware-Updates durchführen, sobald sie mit einem Computer verbunden sind, was den Wartungsaufwand erheblich reduziert. Dies ist besonders nützlich in einem Klassenzimmerumfeld, wo Zeit und Ressourcen oft begrenzt sind.
Wettbewerbsfähigkeit und Anwendung im Unterricht
Beide Generationen sind für den Einsatz in VEX IQ Wettbewerben zugelassen, was bedeutet, dass Schüler mit beiden Generationen an Wettbewerben teilnehmen können. Allerdings bietet die 2nd Generation durch die verbesserten Sensoren und die längere Akkulaufzeit potenziell einen Vorteil in Wettbewerben, in denen Präzision und Ausdauer entscheidend sind.
Für den Unterricht bietet die 2nd Generation eine organisierte Teilelagerung in mitgelieferten kleinen Koffern, die das Klassenzimmer aufgeräumter hält und den Zugang zu den benötigten Teilen erleichtert. Dies erleichtert Lehrern die Integration von VEX IQ in den Unterricht und fördert ein effizienteres Lernen.
Fazit
Die VEX IQ 2nd Generation stellt eine bedeutende Weiterentwicklung der 1st Generation dar, mit Verbesserungen in den Bereichen Elektronik, Sensorik, Programmierung und Benutzerfreundlichkeit. Diese Verbesserungen tragen dazu bei, die Lernerfahrung für Schüler zu bereichern und die Integration von Robotik in den Bildungsbereich zu erleichtern. Trotz der Unterschiede bleibt die Kompatibilität zwischen den Generationen bestehen, was den Übergang für bestehende Nutzer erleichtert und die Investition in die VEX IQ Plattform zukunftssicher macht. VEX bietet ein umfangreiches Angebot an Tutorials, Schulungen und Beispielprogrammen um den Einstieg einfach zu gestalten.

Building Internet-connected robots in an easy way? CORE2 is the answer.
February 2015. Kickstarter campaign of „RoboCORE: the heart of your personal robot” has just started. RoboCORE promises that building consumer robots based on this platform will be much simpler and cheaper than using existing alternatives. 30 days later, with almost $60 000 and 311 backers, campaign is successfully ended. Further R&D, manufacturing, beta tests and RoboCOREs finally goes into the hands of robotic enthusiasts around the world. Since then, thanks to the feedback from hundreds of people, Husarion ecostystem for IoT in robotics has highly evolved and improved. Now this is a stable technology, used by universities, makers and developers. It was time to improve the device and make RoboCORE 2.0. So there it is, named Husarion CORE2: controller for automation & robotics.
Husarion CORE2 RoboCORE
Building Internet-connected products, especially if they aim is not only to store the data, but also to control physical things in real-time, is challenging. Husarion’s mission is to lower entry barrier for new ventures in the area of automation & robotics, as much as possible. They shouldn’t focus on technical issues, but on their customers’ problems – says Dominik Nowak, CEO of Husarion.
Many Kickstarter funded companies decide to launch the next generation of their products also on this platform. Husarion has a different attitude: they don’t promise the miracles, but they give technology that simply works.
If you order now, on the next day your CORE2 will be shipped to you, and all ‘how-to-start’ materials, hardware & software documentations are already available at docs.husarion.com.
Husarion ecosystem overview:
What is special in Husarion’s product? It is not a single product, but a coprehensive solution for companies and developers who build various mechatronic Internet of Things products. Mechatronic means combinations of mechanics and electronics. This is a wider concept than robotics, beacuse apart from robotic lawnmower or telepresence robots, it also includes Internet-connected door lock, electric roller blinds etc.
Husarion provides 3 elements for IoT mechatronic design:
- reference hardware, such as CORE2, RoboCORE and other available in the near future,
- cloud platform to control, update firmware, manage and share connected devices,
- programming framework to write a code that runs on hardware and communicate with a cloud.
The users have access to many examples, professional Real-Time OS based C++ 11 framework and versatile hardware, therefore building working prototype is a piece of cake.
Product is adressed not only to makers, but also for companies. They could use CORE2 to rapidly prototype a preliminary design, and Husarion would help them to elaborate the prototype to mass production ready version. This way they would create the version of CORE2 suited for their product.
Husarion provides also an interface for people who don’t build robots, but just use them. By logging to cloud.husarion.com you can simply add a Husarion-powered device(e.g. made on CORE2) to your user account and see list of your devices:
When you click on device name in the cloud, you will be moved to the user interface specific for this device, created by robot vendor using Husarion framework. If you log into telepresence spy robot, you will see something like this:
If you log into your Husarion powered home automation system, it can look like this:
Husarion enables sharing of user’s devices. It can be done in two ways: by sharing with other cloud user or through the link. Especially the second option is convenient because you can easily give somebody the access to your robot without logging into Husarion cloud.
Husarion provides solution for makers, robot manufacturers, universities, and non-engineeres who want to play with controllable robots. Husarion’s platform is the first one of this kind on the market.
Husarion CORE2
General overview of Husarion ecosystem is described in the previous section. Now let’s dive deeper into Husarion CORE2 hardware details. Specification shown on https://docs.husarion.com/hardware/core2_1_0_0/index.html gives you a glimpse on what’s inside:
The unique feature of CORE2 hardware is a direct support for DC motors with quadrature encoders. Up to 4 motors can be connected at once, and Husarion framework is optimized to control them in real-time without wasting processing power of CPU. It could be done thanks to hardware encoder interface peripherals integrated into timers of STM32F4 microcontroller – the brain of Husarion CORE2. Motors are controlled by PID regulators implemented in background RTOS tasks, separate for each motor. In many professional applications the popular RC servos aren’t enough. Thanks to CORE2, you can easily convert any DC motor with encoder into servo-mechanism that works in accordance with your requirements. If built-in H-bridges don’t suffice, external power driver can be easily integrated.
CORE2 has also the interfaces that allow connecting almost every market-available sensor, or external electronic module. These interfaces are: UART, I2C, SPI, CAN, ADC, microSD card slot, USB host, GPIOs, ADCs, external interrupt inputs, and servo ports powered by built-in DC/DC converter with selectable voltage level.
There are two ways to develop software for CORE2:
- a) offline – using any IDE and SDK downloaded from https://husarion.com/downloads,
- b) online – using a Web IDE integrated to cloud.husarion.com.
Especially the second option is very comfortable, because it allows you to start writing code immediately, without struggles with configuring IDE, installing drivers etc.
Husarion team is doing their best to create comprehensible hardware and software documentation with a lot of examples and ready-to-use templates. They also opened public profile at hackster.io, where Husarion team and community share tutorials on how to use CORE2 in various IoT mechatronic projects.
