It's such a thing with computers in the nursery.

According to many parents, notebooks or tablets that are only used for paddling or watching YouTube do not belong there or may only be used under strict conditions.

However, the new edition of the Lego Mindstorms robot toy cannot do without a computer, because it is there that the robots are brought to life.

The new kit called Robot Inventor consists of 949 parts, including a so-called hub, the robot's brain, and four motors.

One looks in vain for building instructions in the large box.

On the one hand, it is available online as a PDF document.

But you get ahead better if you use the app to build the robots right away, because it guides you step by step and videos give explanations in between.


The application works on Windows 10 computers, Macs, iPads and iPhones, on Android tablets and smartphones as well as on tablets with the Amazon Fire OS operating system.

Building robots with a tablet, regardless of the manufacturer, proves to be particularly recommended in practice.

Lego Mindstorms: Update Hub

You should start with a simple robot like Charlie that can easily remove the hub.

Because before the first robot actions, there is still a tiresome homework to do.

The hub's firmware and operating system must first be updated via the app.

It worked smoothly in the test.

You can also find videos on YouTube that show that this can be a bit tricky under certain circumstances.

In the worst case, all that helps is a total reset by removing the batteries to bring the software update to a successful conclusion.

With this maneuver it is better if the hub is not already connected to other building blocks in a complex way or if it has not been installed in a complicated manner.

You can build five robot types with the new Mindstorms.

Charlie, Tricky, Blast, MVP and Gelo.

Charlie is a cute little assistant robot that comes to life with lots of animations and sounds.

As a little finger and programming exercise, you can let him push a shopping cart.

The Danish designers also came up with a ski board, a mixture of skateboard and skis.

Charlie is sitting on the board.

Then, to move, he has to use ski poles to get anywhere.

Charlie can also be a pretty cool drummer or hand out high fives.

The tasks Charlie and his colleagues can cope with does not depend solely on creativity and skill in putting the building blocks together.

The animations are programmed.

Lego offers two solutions.

Lego Mindstorms uses Scratch or Python


For all those who have no programming experience, Lego uses a scratch-based language that was specially developed for children and teenagers.

More advanced users can also use the powerful and more complex programming language Python.

Therefore, Lego customers also include technical colleges and universities.

One of the robots that the set can build includes Blast, a kind of stoic action hero who can shoot or hammer through obstacles and grab objects.

It can also be programmed to scan its surroundings and fire darts when it senses danger.

There are four motors in Blast, two for moving in space, one for turning the head and one for the arm.

This motor also fires the small plastic arrows when Blast detects an intruder in the children's room, for example.

MVP stands for Multiple Vehicle Platform, which means that with a few modifications, a wide variety of vehicles can be built from it.

This includes a crane or a brisk buggy.

To control MVP remotely, you can set up a modular remote control with the Remote Control Builder in the app.

It can even be used to construct and program a small vehicle that rushes through the room to collect Lego bricks on the floor.

Sporty tricky

Tricky was designed as a sporty robot.

He started his life as a maze runner robot.

Later, the Lego developers also taught him basketball and soccer.

Elements and building blocks from other Lego series can also be integrated into the games.

The red basketball, which is also used in bowling, comes from the Duplo system.

It is impressive that Tricky can also be transformed into a moving drawing robot with a pen holder.

Gelo, who walks on four legs, made the strongest impression in the test.

The toy is very reminiscent of the four-legged robotic attack dogs that the former Google subsidiary Boston Dynamics developed.

Gelo isn't that scary, it's just cute.

He uses all four engines in the set.


In order to move the legs, all independently.

Gelo can run or run slowly, curve objects or perform other tricks if you manage to cast the movements in program codes.

When the robots learned to dance

It was only in December that Hyundai took over 80 percent of the robotics company Boston Dynamics.

Now it can be seen that the money was well invested.

Because the robots can now even dance - and almost scary well.

In order to get the programs running on the robots, you don't have to be constantly connected to the tablet or smartphone via Bluetooth.

The programs can also be downloaded to the robot's hub and run locally.

Unfortunately, in contrast to the previous Lego Mindstorms EV3 system, external devices such as a webcam can no longer be connected via USB.

The USB socket in the hub is only used to charge the battery.

With a manufacturer's recommended price of around 360 euros, Mindstorm's robot inventor is one of the most expensive Lego products.

In view of the various possibilities that this educational toy, which is intended for ages ten and over, does not seem unreasonably large, especially since the market price is up to 100 euros cheaper.
