We have only speculation and fossil remains to tell us what dinosaurs might have been like. However, the human imagination is a wonderful thing, capable of creating new and wonderful innovations. With the Meccano Meccasaur kit, you can spark your imagination and build and play with your own robotic dinosaur.

What is a Meccano Meccasaur?

A Meccano Meccasaur is a three-foot-long buildable T-rex. Build your Meccasaur and prepare for chomping, stomping and lots of programmable fun.

Meccasaurs are highly customizable and highly interactive, with tons of features and a huge personality. They respond to affection, and can even be set to guard your possessions.

What’s in the Box?

  • 715 Meccano pieces
  • Motorized Meccasaur Module for controlling movements
  • LED module for flashing eyes
  • Meccasaur brain
  • Two hand tools
  • Instruction manual

First Thoughts

As with most Meccano sets, the packaging for this one is stellar. The front of the box features the dinosaur in action. All you have to do is slit the tape with scissors and open the box.

Inside the box, the contents are well-organized into divided sections, so that you always know what part is where. Everything is clearly and concisely labeled.

Building this robot takes between five and seven hours though it feels like it takes less time. The instructions are easy to follow if you’re familiar with Meccano sets, but there are a lot of them.

This robot is designed for children ten and up. Younger children may enjoy the completed dinosaur, but the build is likely far too challenging for them. There are seven hundred fifteen pieces to this behemoth of a dinosaur, so you will need to be careful to not lose any of them.


The Meccano Meccasaur is a green and gray T-rex dinosaur. It stands at three feet tall and can roar, stomp and growl. This massive dino sports a pair of light-up LED eyes and a moving mouth, legs, head and tail.

This robotic creature  is made of sturdy plastic Meccano pieces, and this set is definitely able to be used with other meccano sets you might also have.

How Does It Work?

The Meccano Meccasaur comes with a Meccasaur brain. This brain allows the robot to be programmed, as well as to provide responses from all the input of the dinosaur’s various sensors, such as the sound sensor or the touch sensors that tell it when it is being petted.

When it comes to interacting with the world, the Meccasaur is a master. It comes with a number of sensors including sound and touch sensors that will allow it to receive input from you. This dino is also capable of making a number of sounds and stomping and chomping, just like a real dinosaur.

The Meccano brain makes this robotic reptile perfectly programmable. You can teach it commands such as walk forward, turn, lunge, and roar. Your Meccasaur can also be taught to answer questions like a magic eight-ball.

As an aside, your Meccano Meccasaur can walk decently fast. It should also only be run on a flat surface. It doesn’t have obstacle detection and it can’t do stairs.

The Meccano Meccasaur takes four C-cell batteries. Unfortunately, these are not included and will run you about $7 so do be aware of that.


The Meccasaur is completely interactive and completely programmable, and unlike many of the other Meccanoid robots, this one does not require an app on your phone.

Everything can be handled through simple button presses, which decreases the frustration for children who may be playing with this robot. There are a number of exciting things your Meccasaur can be programmed to do, and you are in charge of which ones you choose.

Magic Eight-ball

Of all the Meccasaur’s modes, this one was our favorite. In this mode, your dino answers yes or no questions with a variety of responses, just like a magic eight-ball… if a magic eight-ball was three feet tall and could move.

Guard Mode

Do you have something special you need kept safe? No worries! Meccasaur has you covered. In guard mode, your ferocious dinosaur pal will growl, lunge and attack anything that gets in front of its sensors or makes a loud noise. Your little brother will never sneak into your room again.


Your Meccasaur can be programmed to walk in a variety of directions. It can be programmed to walk forward, backward and turn. In this way, it is possible to guide your dinosaur.


In addition to all the things you can program your Meccasaur to do, it also features a number of sensors for interactive play. It can recognize changes in light, loud noises and touch. It reacts with pleasure when petted, roars when spoken to and may lunge and stomp if something gets in front of its light sensor.


This ends our Meccano Meccasaur review. This dinosaur is impressive in size as well as what it can do. It roars, chomps and stomps. It is also programmable, and you don’t even need a phone app to make the magic happen.

As with all things, there are a few downsides to this dino. For one, the build can be complex, and though the instructions are easy enough to follow, if this is your first Meccano set, it may be a bit confusing for you.

Another downside is the batteries. The Meccano Meccasaur takes four C-cell batteries. These are not included though C-cell batteries are available from most retailers.

Despite those downsides, however, this dinosaur is a lot of fun. It packs a lot of wow factor and personality and can interact with you in a lot of ways. If you are a fan of Meccano building sets, or want a project to do with your child and don’t mind the five to seven-hour build time, this one might just be perfect for you.

      Hmmm that’s odd. Do you think you could send over a picture? It’ll help to see how it looks. My guess is that there might be some issue with the weight distribution.

    2. My 8 year old finished building his meccasaur today and had the same problem. It was a weight distribution issue resulting from a couple parts being attached incorrectly. Make sure that the flat plastic piece shown in instruction step 46 is bolted through the correct hole. Also, make sure the metal bar in step 120 is properly secured using the rubber bushings. My son couldn’t get them onto the bar, but after I attached them it is much more stable.

  1. Did anyone else notice how the pictures of where pieces should be bolted changes… for example in step 25 it shows the silver piece on the end toward a back of foot but on step 26 it’s moved two spots to the left? Very confusing.

    1. I just began building one for my grand-daughter , I have a couple of hours a night, past my bedtime but, there is that discrepancy. Made me doubt the accuracy of what followed, I’ll know better tonight. The proper placement is the original assembly instruction, two spots to the left. Too late to help you I’m sure but maybe someone else.
