LEGO Mech Sets aren’t just another LEGO set for kids. They’re inspired by science fiction themes and Japanese robot anime, and inventing different kinds of mech from LEGO mech sets can keep everyone entertained and interacting for hours.
What Is a Mech?
A mech or mecha is a large, walking robot. In the first science fiction to include mechs, written in the 1800s by such authors as Jules Verne, they were steam-powered. Depending on the science fiction or anime world that inspired it, the mech may be controlled by remote control or by a pilot seated in a cockpit in the head or chest of the mech. In most science fiction and anime, the mech is an armored fighting machine equipped with a large arsenal of weapons. In some of these science fiction and anime worlds, though, mechs are put to a variety of non-military, day-to-day uses.
Benefits of Playing With LEGO Mech Kits
While much has been written about how children benefit from construction play and playing with LEGO sets, adults who play with LEGO kits benefit in the same ways as children and continue to benefit as they create increasingly complex models. Building mech with LEGO Mech Sets develops imagination, story and character creation skills, problem solving and logical thinking, mathematical abilities, engineering skills, the ability to work with spatial relationships, and attention to detail. Parents who talk with their children about building different kinds of mech and the LEGO world of which that mech might be a part improve both their and their children’s imagination and their ability to express the ideas that they have in their minds so that others can envision them and help to create the physical reality.

The Basics of Building a Basic Mech
Mechs can look like tanks on legs, animals, insects, reptiles, lizards, or humans.
One mech builder recommends starting with the legs, as these provide support for whatever type of mech you build. To make it easy, you can skip the knees, but the knees can bend either way, like bird knees or human knees. The legs need to be strong enough to support the head, torso, cockpit, arms, and weapons or tools that your mech will carry.
Like the legs, the torso also needs to be strong. You can change the proportions to create humanoid mechs of different ages, but for a basic mech, the torso should be the same length as the legs. The head should be one-third the length of the torso, and the feet should be one-half the length of the head. The elbow should be positioned even with the midpoint of the torso with the wrist even with the groin.
The cockpit can be built attached to the outside of your torso, inside the torso, or inside the head of your mech, so either the head or the torso needs to be large enough to hold a mini figure. That will effect the overall proportions of your mech.
When building the torso of your mech, don’t forget to include places to attach the legs and arms or the hind legs and forelegs, as the case may be. You will also need attachment points for anywhere that you might want to add weapons, tools, or other accessories to your meck.
Attaching the arms and legs or all four legs to the torso is the next step.
If you haven’t built the torso around the cockpit and the mini figure, then the next step after you attach the arms and/or legs is to attach the cockpit and the weapons and/or tools your mech needs to the torso. The weapons and tools can go wherever you think they will work best for your mech and its pilot – on the back, arms, legs, or head.
Finally, your mech will need armor to protect it and its pilot as it fulfills its mission. Putting the armor around the cockpit, the torso, and the legs and arms gives your mech a bulkier, stronger look.
Mech Building Supplies Recommended by Mech Builders
Ball and socket hinges — for strength when building larger mechs.
Plate or brick hinges.
Technic hinges – for strength when building larger mechs, also called pins or Exo-Force hinges.
Pnemuatic-tbar hinges – for joints.
Travis bricks – especially good for smaller scale mechs.
Mech builders recommend testing the joints and hinges when you are building a larger mech to make sure that they are strong enough to provide the needed support while also providing the flexibility to pose the mech.
Advanced Mech Building Tips
As mentioned above, changing the body proportions of humanoid mechs changes the apparent age of the mech. The human body proportions at different ages are as follows:
Infant – The torso should be one and three-fourths the length of the head and the legs should be one and one-fourth the length of the head. The torso is longer than the legs. The overall height of the mech should be four times the length of the head.
Ages one to two – The head should be one-half the length of the torso, and the torso and legs should be equal to each other. The overall height of the mech should be five times the length of the head.
Ages three to four – The head should be one-half the length of the torso. The feet should be one-half the length of the head, and the torso and legs should be equal to each other. The overall height of the mech should be five and one-half the length of the head.
Ages five to seven – The head should be one half the length of the torso and one-third the length of the legs. The legs are longer than the torso. The overall height of the mech should be six times the length of the head.
Ages 11 to 15 – The head should be one half the length of the torso and one-third the length of the legs. The legs are longer than the torso. The feet should be one-half the length of the head. The overall height of the mech should be six and one-half times the length of the head.
Adults – The head should be one third the length of the torso, and the feet should be one-half the length of the head. The torso and legs should be equal to each other. The overall height of the mech should be seven and one-half times the length of the head for a female mech and eight for a male.
To create a mech that duplicates the proportions used in fashion illustrations, the head should be one-third the length of the torso and one-fifth the length of the legs. The torso and legs are not equal, and the feet should equal the length of the head. The overall height of the mech should be
10 times the length of the head.
For figures created using either realistic or fashion proportions, the elbows fall at the center of the torso. The hands of an infant end at the crotch while in older figures the wrists end at the crotch.
Study photos of young animals to duplicate their proportions at different ages, but one thing to note is that very young animals like horses, deers, and giraffes that rely on running to escape predators are born with long, gangly legs.
When creating humanoid mechs, take a tip from puppet makers and avoid trying to go for a look that is too realistic. If you should want to create a mech that resembles a celebrity or a figure in the news, though, follow the lead of cartoonists and choose some notable and readily recognizable features to emphasize.
To be able to create mechs with the greatest range of motion, use double elbow and knee joints.
Starting with a LEGO Mech Kit provides instructions for building mechs for characters from movie and television shows. The connection to a favorite movie or television show provide an incentive that encourages children to finish building the kit in spite of difficulties and challenges. These kits reduce the frustration of figuring out how to build mechs from scratch while offering inspiration to you and your kids for designing your own mechs.
