Which LEGO robot kits are best?

Building LEGO toys has long been a favorite pastime for kids of all ages. Over the years, the LEGO brand has expanded to all kinds of different kits — from Adidas sneakers to the Hogwarts Castle and lifesize tropical plants. However, some of the most popular kits today are LEGO robot kits. With robots, the fun doesn’t stop when the building is finished. Some LEGO kits feature programmable robots with sensors and motors that can move around and complete tasks.

One of the best LEGO robot kits is the Mindstorms EV3. This exciting kit is transformable into 17 different designs, each with programmable commands.

What to know before you buy a LEGO robot kit


Some of the more advanced LEGO robot kits are programmable. After all, this is what makes a robot a robot. These LEGO robot kits use motors and sensors that allow your robot to move around and complete tasks using rollers on their feet. Think of them as a remote-controlled RC car, but with arms. Once the robot is complete, you can go online and download user-created programs that you can control your phone or tablet. LEGO even has a Robot Commander App that you can use to program the Mindstorms series.


Model robot kits are non-programmable and designed as stand-alone toys. While some have moving parts like arms and legs, they don’t move on their own using motors or sensors. Model kits are generally easier to put together and require less complex instructions. Another benefit of model robots is that they offer a wider array of styles, including Star Wars and Ninjago.

Age range

Age range basically refers to skill level. The older a child is, the higher their skill level will be to put together more complex robot kits. The more complicated programmable robots, such as the Mindstorms kits, ask that the assembler be at least 10 years old. The non-programmable Ninjago Salvage robot is suitable for children starting at age 8.

What to look for in a quality LEGO robot kit


Some of the more advanced (and most fun) robot kits are also transformable. For example, the Mindstorms EV3 robot comes with 601 pieces, 3 different motors and multiple sensors. All of these pieces allow the robot to take up to 17 different character designs. The tallest version is called SPIK3R, which takes the shape of a robotic scorpion and stands over 16 inches high and 14 inches long. 

STEM education

Science, Technology, Engineering, and Mathematics is a type of education that encourages students to learn about engineering solutions to problems. So naturally, LEGO wanted to give children the opportunity to learn these skills by playing with toys. There are many types of quality LEGO robot kits that help children learn about engineering. Mindstorms, DUPLO and LEGO BOOST are just some versions of its toys that use STEM education.


LEGO robot kits that use motors are a part of the programmable type of kits. These motors allow your robot to execute tasks and move around the environment. The robot can move its arms to pick up objects, turn its wheels to go from point A to point B and use its tools to interact with its surroundings. Alongside the coding that you input, these motors can do more complex tasks like play guitar, knit sweaters and solve a Rubik’s Cube. 

How much you can expect to spend on a LEGO robot kit

LEGO robot kits cost anywhere from $40 all the way up to $650 for the most complex, programmable robots.

LEGO robot kits FAQ

Why are the programmable LEGO robot kits so expensive?

A. You shouldn’t underestimate the complexity of the programmable robot kits like the Mindstorms. LEGO uses many electronic parts that include multiple motors and sensors for color, infrared and touch. It also includes a USB connection so you can program the robot on your tablet or laptop. All of these expensive electronics add up to create a costly engineering toy. 

Are LEGO robot kits fun for adults too?

A. Yes! Adults can absolutely enjoy LEGO robot kits. These kits are designed to teach kids about problem-solving and allow them to learn about the basics of engineering. If you’re new to engineering as an adult, LEGO robot kits can be a great way to dive headfirst into a new hobby. Also, what better way to learn about programming and coding than by teaching a LEGO robot to play chess.
