Hub-to-Hub Communication Brings New Possibilities

Hub-to-Hub Communication Brings New Possibilities to MINDSTORMS

MINDSTORMS recently added a new feature to the Robot Inventor that allows creators to connect two or more hubs together. These new programming blocks allow for new and creative multi-hub projects where one hub can communicate with another. Hub-to-hub communication opens up endless possibilities for creating remote control applications, dance companions, games, and complex animals.

Below are some inspirational projects that use two or more hubs that are created by the ROBOTMAK3RS, a global community of robot experts. You can find most of these projects in the official the MINDSTORMS App in the Community section. Both building instructions and code available for you to try out.

Get ready for a competitive, fast-paced multi-player game. Sanjay and Arvind Seshan (USA) create a quick-to-build multiplayer racing game called Color Catcher. This game allows two players to race to the color that is displayed on the hub. Players navigate their robot by using the buttons on the hub to pick a direction and then tap on the hub itself to make their robot move in that direction. The first player to successfully “catch” the color scores a point.

Dimitri Dekyvere (Belgium) and Laurens Valk (the Netherlands) use two hubs to create an engaging balancing robot with an accompanying remote control. Using the joystick, you can control the Balancing Bot with your second hub.

Always dreamed of training to become an astronaut? With the Shuttle Simulator by Nard Strijbosch (the Netherlands) you can start your journey! Nard uses two hubs to create a Shuttle Simulator that is sure to test your piloting skills. One hub serves as a shuttle and the other as the controller. The player can fly the shuttle using the controller.

You may have thought that Charlie is an excellent drummer. It turns out Charlie is also an excellent dance instructor! This fun and interactive project is sure to bring a lot of smiles. Anika Brandsma (the Netherlands) recreates a Dance Class using two hubs. The human dancer holds a hub in one hand and imitates Charlie’s movements.

If you have more than two MINDSTORMS sets, you might enjoy creating this amazing snake by Anton Vanhoucke (the Netherlands). The snake avoids obstacles and can even follow lines using a color sensor. Adding additional segments is extremely easy. Anton has put in much effort to ensure that the movement of the snake is as realistic as possible. You are sure to enjoy watching your Robot Inventor Snake slithering across the floor. This model is available for purchase directly from Anton.

MINDSTORMS Retires!

2023 is the 25th Anniversary of the MINDSTORMS brand. For 25 years, MINDSTORMS has educated and inspired a generation of robot builders, both children and adults. Unfortunately, the LEGO Group decided to end the line on December 2022. Many ROBOTMAK3RS have been passionately involved with the development of MINDSTORMS through the MUP and MCP programs. Even with the newest Robot Inventor line, several ROBOTMAK3RS were invited to submit additional bonus models that were included in the official app. Regardless of the retirement of a major LEGO robotics product line, ROBOTMAK3RS continue to MAKE-SHARE-INSPIRE using all LEGO robotics platforms available to us. Here is the official statement from LEGO. Since its launch in September 1998, LEGO MINDSTORMS has been one of the core ‘Build & Code’ experiences in the company’s portfolio, carrying with it significant brand equity and becoming a stand-out experience for the early days of consumer robotics and leading to current Build & Code

Celebrating MINDSTORMS with a Remix Part 1

In honor of the 25th Anniversary of MINDSTORMS, we asked ROBOTMAK3RS to combine a LEGO set of their choice with a MINDSTORMS set. Here is what these five ROBOTMAK3RS came up with. MINDSTORMS Chess Assistant by Arvind Seshan Overview: When you are new to chess, it can be a challenge to remember which pieces go where. Now, you can use machine learning and LEGO MINDSTORMS Robot Inventor to build a tool to help you learn where all the chess pieces go on the chess board. Sets used: LEGO® Iconic Chess Set (40174) and MINDSTORMS Robot Inventor (51515) Review: I really like how the chess set base can store all the pieces underneath and that the board neatly splits in half for handy storage. The chess pieces themselves are very sturdy and well built. My only criticism is the building of the box itself. It was quite difficult to see what pieces to use and since the entire box is made mostly of thin plates, it took a lot of time and patience. I would have liked the storage area to be sliding dra

Machine Learning Meets MINDSTORMS

Machine Learning Extension LEGO MINDSTORMS announced today a brand new feature that is sure to excite all users. Machine Learning Extension is coming to the software in August 2022. This will allow users to implement new applications that were not possible before. Machine Learning has become exceedingly popular in recent years with applications in all sorts of industries from robotics to financial services to climate change. Now, even the youngest of robot enthusiasts and programmers have access to the world of Machine Learning and Artificial Intelligence. Comparing two classes Machine Learning on MINDSTORMS will work with both images and audio. For instance, you could train your model to recognize smiles and frowns on your face and have the emotion displayed on your hub. You could train your model to recognize when a red ball is present or not or identify a particular LEGO element. You can control your robot with audio commands that use your own voice. It is exciting to see what new p
