5 characters, interactive step-by-step building instructions, action programming, intuitive remote control.
Long and complicated assembly.

What is not in the huge park of Lego products. The Danish company has launched the production of sets for the smallest ( Lego Duplo), separate series for boys and girls, but the most technologically savvy are the newly-made lines of designers with remote control support. Lego Boost 17101 is one of them for kids aged 7-12.

From a set of parts in the amount of 847 pcs. You can collect as many as 5 characters: Vernie the robot on caterpillars, Frankie the cat, an all-terrain vehicle, a guitar and an automated assembly line. Each of these toys performs a number of its functions. For example, the Verny robot rides on a caterpillar, expresses emotions with eyebrows, knows how to determine the distance to an object and its color. The cat purrs, enjoys strokes and plays the harmonica. The all-terrain vehicle is programmed for shooting at targets, raising and lowering the bucket, knocking with a hammer. The guitar will help to perform cool hits. Finally, automated assembly of mini-robots has been set up on the conveyor.

Each of the five heroes gathers for several hours. Hints on the assembly process are interactively given in the Lego Boost mobile app. At first, it clearly shows what needs to be moved and where, where to click. Gradually, the understanding of the skills of the hero comes to the child and he can programme the assembled toys to perform a whole galaxy of actions. Robots play sounds through the speakers of a paired smartphone or tablet.

You won't get bored with this set. Lego Boost 17101 develops fine motor skills in children, logical thinking skills, teaches the basics of programming. And most importantly, it allows you to diversify the gameplay at times, relying on the creative imagination of the child. The payment for the comprehensively developed qualities of the designer is a non-acidic price tag for the product. But, frankly, the set is worth every penny spent.

Self-propelled locomotive, two trailer cars, passenger platform, 6 character figurines, track structure elements, remote control.
The mobile app is not supported by all smartphones.

Lego Express Passenger Train 60337 is a miniature steel railroad building set. A constructor is assembled from 764 parts of a block-type connection.

The railway is built in a circle using 16 curved and 8 straight track elements. A locomotive moves independently along the tracks, which pulls 2 passenger cars with wide doorways to allow passengers in wheelchairs and with bicycles to enter. The electric locomotive is equipped with a decorative pantograph, a spotlight with brightness control, it also has a driver's cabin, in which one of the characters' figures can be placed.

Passengers await the arrival of the train on the platform. For the convenience of passengers, a bench is installed on it, there is an info board with the train schedule and a green decorative tree. The set includes 6 character figures, laptop, phone, bicycle, wheelchair, briefcase, backpack and hot dog minifigures.

The joystick to control the train can be assembled from Lego bricks. An alternative to it will be a smartphone with a pre-installed app LEGO Powered Up. The programme is not always installed correctly on Android smartphones, so the presence of a joystick will come in handy here. The remote control is powered by AA batteries, the locomotive moves from the same batteries. Batteries are not included in the kit. Lego Express Passenger Train 60337 is an interesting offer for young fans of railways who spend long hours playing with trains.

Self-propelled properties, four-wheel drive, differential lock, working suspension for all 4 wheels, confident off-road conquest, several control options from a smartphone.
There are no significant downsides.

Assembling the Lego 4x4 Mercedes-Bezn Zetros Trial Truck 42129 off-road truck model opens up the exciting world of engineering, allows you to learn the principles of operation of various mechanisms and the features of their use in practice.

The truck is assembled from a large number of block construction parts (2110 pieces). Realism adds to it a working suspension for all 4 wheels and a differential lock function to conquer off-road. The self-propelled qualities of the model are determined by the use of powerful electric motors with all-wheel drive on all wheels of the car. The movements of the truck are supposed to be operated through the LEGO Technik CONTROL + mobile application, in which several on-screen control options are available (including using a gyroscope).

The careful study of the model is supported by a detailed gearbox with a service hatch for its inspection. The truck also has opening doors to the cab and hood. When assembled, the dimensions of the SUV are about 48 cm long, 19 cm wide and over 21 cm high. The car's electric motors are powered by six AA batteries. Batteries are not included in the delivery set of the designer, so they will need to be purchased separately.

When assembled, the truck can race across rough terrain, conquer simple off-road conditions, or travel around the interior of the home, climbing steep hills. The assembly of the designer develops creativity, concentration, perseverance and fine motor skills of the hands. The off-road truck made of Lego parts will appeal to both teenage children and adult fans of designers from the popular Danish brand.

Self-propelled features, adjustable tracks, blade, ripper and ladder lifts, multiple smartphone control options.
Increased build complexity.

Equipment from the mining industry is amazing in its size and capabilities. The model of a bulldozer in miniature Lego App-Controlled Cat D11 Bulldozer 42131 is classified as such.

Over the assembly of the bulldozer will have to sit down for a long time. It's no joke, this set consists of 3854 parts. According to the age limit, the designer is marked with the badge "18+", which is assigned to the most complex models in terms of assembly. The colossus moves on a caterpillar drive with the ability to adjust the tension of the tracks(as is implemented in real bulldozers).

You can bring the model to life through the LEGO Technic CONTROL+ mobile app, which offers several options for on-screen control of vehicle movements. At the same time, the blade, ripper and ladder are raised and lowered from the smartphone. To work in an impromptu quarry, the bulldozer will be ready, provided that it is additionally equipped with batteries - six batteries of the common type AA.

The finished model of the bulldozer measures about 57 cm long, 37 cm wide and 26 cm high. The mediative process of assembling the designer develops imagination, attention, creativity, fantasy and fine motor skills of the motor apparatus. Lego App-Controlled Cat D11 Bulldozer 42131 is a model of serious mining equipment of increased complexity, addressed to an adult audience.

5 intelligent motorized robots per set, programming via mobile application, color and distance sensors.
Increased build complexity.

The first programmable Lego robot appeared on store shelves back in 1998. It started the Mindstorms series. The current generation of Lego robots is presented by the Robot Invertor 51515 set from the 2020 model range.

From one box of the designer, the user has the right to collect 5 robotic characters at once. The highest of them is called Explosion. He is 36 cm tall, can make his way through obstacles, shoot and grab objects. The second robot is named after Charlie. This is a kind of dancing merry fellow who plays the drums. The four-legged Gelo can run around obstacles and perform tricks. The cunning robot Tricky (play on words in English) is fond of sports: football, basketball, tennis and even boxing. Finally, the fifth piece of the set is the MVP modular vehicle platform.

All five characters have a total of 949 parts. Assembling robots requires the correct sequence of actions and increased care. The fun begins later - the Lego MINDSTORMS Robot Invertor application provides a programming environment based on the Scratch language. More savvy "programmers" can write commands to robots in the Python language. Block characters from the set perform tasks and missions according to pre-programmed algorithms.

The construction kit includes a rechargeable Li-Ion battery, color sensors (8 colors are distinguished) and distance sensors for detecting obstacles. The set makes a great gift for any occasion for boys aged 10+ and adults with an engineering mindset. After all, robots animated by a wave of the hand cause real delight at any age, whether they are under the supervision of schoolchildren or already gray-haired pensioners.
