Robots Weblog | Variations between VEX IQ 1st Technology and VEX IQ 2nd Technology

The VEX IQ platform is a modular robotics system specifically designed for the educational sector. Since the introduction of the 1st generation in 2012, the technology has evolved significantly, leading to the introduction of the 2nd generation. With the introduction of the 2nd generation of VEX IQ There are some significant differences and improvements compared to the 1st generation. This article highlights the most important differences between these two generations.

Electronics and Compatibility

A key difference between the two generations is in the electronics. The 2nd Generation includes modernized electronic components that are compatible with the older 1st Generation components. This means that teachers and students who already have 1st Generation kits can easily upgrade to the 2nd Generation without rendering their existing components unusable.

One beneficial difference is the introduction of a new battery in the 2nd generation, which uses lithium-ion cells and offers a significantly longer runtime without a drop in performance. However, the new battery is not compatible with the 1st generation charger, which must be taken into account when charging. However, the battery can now be easily charged via USB-C without a special charger.

Sensors and motors

The 2nd Generation offers improved sensors, including a new laser-based distance sensor that uses a safe Class 1 laser to provide more precise measurements. The new optical sensor offers better performance in low light conditions and can even measure approach speed.

Another significant advancement is the integrated 3-axis gyroscope and 3-axis accelerometer in the 2nd generation Robot Brain, which enable more accurate positioning. In contrast, the 1st generation only has a 1-axis gyroscope.

Both generations have powerful smart motors, but the 2nd generation already comes with Omni-Wheels, which allow for improved mobility of the robot. These wheels allow the robot to move in multiple directions, which significantly increases maneuverability.

Programming options

The 2nd generation brings with it expanded programming possibilities. While the 1st generation was mainly programmed with ROBOTC, but is now also compatible with the new software, the 2nd generation fully supports VEXcode, which includes programming languages such as Python, Blocks and C++. This offers greater flexibility and adaptability for different educational levels and learning goals.

This software is available for various platforms such as Windows, macOS, iOS and Android and makes it easy to get started with programming. The ability to switch from a graphical to a text-based programming interface makes it easier to transition to more complex programming languages.

Easier program transfer: The programs can be transferred to the robots via the radio controller. For Apple and Android systems, data transfer also works directly via Bluetooth.

Mechanical components and construction options

The mechanical components of the 2nd Generation have also been improved. The kits include new and improved parts that offer more building options and significantly improve the way the robots are built. These improvements were developed in close collaboration with STEM educators to maximize educational value.

Ease of use and maintenance

Another benefit of the 2nd Generation is simplified firmware updating. The new Robot Brains can perform automatic firmware updates as soon as they are connected to a computer, which significantly reduces maintenance effort. This is especially useful in a classroom environment where time and resources are often limited.

Competitiveness and application in teaching

Both generations are approved for use in VEX IQ competitions, meaning students can compete with either generation. However, the 2nd generation’s improved sensors and longer battery life potentially give it an advantage in competitions where precision and endurance are critical.

For classroom use, the 2nd Generation offers organized parts storage in included small cases, keeping the classroom tidier and making it easier to access the parts needed. This makes it easier for teachers to integrate VEX IQ into the classroom and promotes more efficient learning.

Conclusion

The VEX IQ 2nd Generation represents a significant evolution of the 1st Generation, with improvements in electronics, sensing, programming and usability. These improvements help enrich the learning experience for students and facilitate the integration of robotics into education. Despite the differences, compatibility remains between generations, making the transition easier for existing users and future-proofing the investment in the VEX IQ platform. VEX offers an extensive range of tutorials, training and sample programs to make it easy to get started.
