The information that LEGO has discontinued the Mindstorms product line is bittersweet for me. I purchased my daughter a LEGO Mindstorms equipment for Christmas in 2000 when she was solely three years previous. My aunt, who was on the town for the vacations, accused me of shopping for it for myself.
Guilty.
However, my daughter and I had a number of enjoyable constructing issues that moved with that preliminary LEGO RCX Mindstorms equipment, even when my daughter didn’t know tips on how to program the robotic on the time.
Fast ahead to 2013, I volunteered to assist mentor and begin a FIRST LEGO League workforce at my son’s elementary college. My ardour for all issues FIRST-related has solely grown within the ten years since that first workforce.
It’s what reignited my ardour for robotics, impressed me to take a job main the cellular robotics product workforce at Adept Technology (now OMRON) in 2014, and it’s what impressed me to discovered The Mobile Robot Guide publication in 2018.
So yeah, LEGO Mindstorms had a huge impact on my profession and my ardour for cellular robots. One of the founding members of our unique FIRST Tech Challenge workforce lately graduated from Yale with a level in pc science and began his profession on the notion engineering workforce at Skydio Drones.
I’m proud to say that I’ve impressed greater than 100 children in our group to think about careers in a STEM-related subject, by the thrill of aggressive robotics.
Alas, all just isn’t misplaced. While LEGO has determined to retire the LEGO Mindstorms model, the LEGO Spike Essentials Kit is now the centerpiece for the FIRST LEGO League competitions, though any of the prior launched Mindstorms elements are authorized for competitors.

The LEGO SPIKE “brain” is a bit smaller than the Mindstorms EV3 mind. Both use the identical software program and the motors and encoders have related energy and determination. The large distinction is that the SPIKE kits’ motors and sensors are extra rectangular than the sooner Mindstorm fashions. This function allows the development of rather more compact robots with SPIKE than with prior generations of Mindstorms kits.
The Lego Mindstorms system has three generations. The Robotics Invention System, which was launched in 1998, was the primary. The subsequent era, known as Mindstorms NXT was launched in 2006. This was adopted by the Mindstorms EV3, which was launched in 2013. There had been numerous each retail and academic kits at every era of Mindstorms.
When it got here out in 1998, the primary Robotics Invention System used the RCX programmable brick (Robotic Command eXplorers). It could possibly be programmed with RCX or ROBOLAB based mostly on LabVIEW. Chris Rogers’ software program from Tufts University was offered by National Instruments. The RCX had 32K RAM and ran at 16 MHz. The brick got here with two motors, two contact sensors, and one mild sensor.
The LEGO NXT equipment of the following era had three servo motors and one sensor for mild, sound, distance, and contact. Another contact sensor was added to NXT 2.0. The NXT brick had 64 KB of RAM and ran at 48 MHz. ROBOLAB was within the schooling equipment, however NXT-G was within the retail set.
Linux is the core working system of the final era of LEGO EV3 brick. It included a processor with 300 MHz, 64 MB RAM, and 16 MB Flash reminiscence. It was in a position to connect with WiFi, Bluetooth, USB, and Micro SD. The instructing set ran on LabView and had two large motors, one medium motor, two contact sensors, one coloration sensor, one gyroscopic sensor, and one ultrasonic sensor.
If you’ve any of those unique Mindstorms kits, there may be an energetic secondary market on Ebay in addition to different LEGO brick-selling companies for used LEGO gadgets. Or you’ll be able to simply dangle on to them for the grandkids, like I’m doing.
