EMME "Technology is not complicated"

He is a 3D printed robot and an example of a prototype who represents a new form of sketching, design, and create

Similar projects worth following
Emme doesn't use wires, screws or connectors and has a different shape, you can put all the pieces together in seconds or you can use only one wheel as a 360º motorized selfies machine, he can follow you and he can go on road, offroad, on water and underwater.

It's not about the robot, it's about think, sketch and build in a different way.

If you accept the challenge of leaving behind the screws, wires and connectors, and design 3D parts very thin (no more than 0.8mm or 1.2mm) you are ready for change, to evolve.

After that, your ideas have not barriers. Normally when a robot is designed, the screws, wires, connectors and solid parts, canalize the final design to a rigid and obsolete format. That STOP and PUT WALLS on the genuine ideas and finally on the results.

This new design path, give you the capacity to keep the original idea and make it a prototype, in just weeks instead several months.


Hi I´m Salvador from Calpe/Alicante/Spain, the creator of Emme, a robot created in a six weeks challenge. The catchword of my robots is "Technology is not complicated", and that's because you can use the things who everybody uses to make a robot in a different and simple way, getting a different and wonderful result.

Emme has a different shape and each part can be used separately, that's because each principal part has its own microprocessor, wifi module, and battery. You can put all the pieces together in seconds or only use the wheel as a 360º motorized selfies machine. Emme can go on road, off-road, water and underwater.

It's about using the same tools to get different and better results.

This new design path accelerates the time from the idea to the prototype, now you only need some weeks instead several months.

I want everybody knows about Emme and that helps to change the way to create robots. 


I was thinking of making a new robot whose parts will work separately, a robot who can go with me everywhere and without wires or connectors, in that way I could put all the pieces together and dismount in seconds.

I spoke with my wife: "Normally I need months o a year to make a new robot: sketching, mechanical parts 3D modeling, 3D printing, hardware, connexion diagrams, prototype, wiring, software, it's too much work" But "I think I can do it in six weeks, really I think I can" My wife told me: "Ok do it, but do it as a six-week Challenge and upload a video on youtube every day, that is going to encourage you to aim you challenge".

That is the video of the presentation of the Challenge:

The Facebook page OF THE CHALLENGE:

In that moment my daughter has one year and a half, every morning I drew sketches with her, one-half of the paper for me and the other half for Belén, in the afternoons and nights I worked on Emme "3D printing, 3D drawing, hardware design and testing software".

Some days at breakfast Belén play spontaneously with the prototypes.

Finally, six weeks after the challenge was achieved and  I present Emme in my Youtube Channel and on a Facebook page, this is the video. ( 144.155 people reached on Facebook ). 

Testing Emme on the Rocks.

Testing Emme on the sea.

Testing Emme at night, I love how Emme glows.

After achieving my personal Challenge I decided to make three more models for Emme: Offroad, Water, and Underwater. Six months after, everything is ready and I launched the Kickstarter campaign the first day of June. 


Emme its a 3d printed robot without cables or connectors, all of its parts can work separately.

You control it with a Prism.

You do not need your phone or anything to control the robot, but you can put your sports cam on Emme and see the images with your cell phone while you control Emme with the Prism.

You can use only one wheel motor to make 360 selfies, one again you do not need anything more than the control prism to play with Emme, take advantage of this and put your phone on Emme to make the 360 ºSelfies:

You can mount it in seconds.

Put all the parts on your backpack and you are ready, change the Emme city accessories to the water accessories in seconds and start again.

You need a cameraman with you, Emme is your cameraman, take with you the GPS bracelet and Emme follow you and record the scene.

He loves the city, goes offroad, navigates on the waves or dives looking for a treasure:

Be creative!

Emme is a printed robot, you can make new parts when you need, or create new accessories.

From a maker to makers will be a Ready to Run Emme and Makers Kits to do it yourself.

There is no similar robot in the market, with Emme you do not need tools to mount it, or connectors, you can play with all of the parts or only with some of them, and when you want to make...

    No wires, no connectors, no screws, Let's go!! 

    I feel really good teaching with Emme concepts, Now after 3 weeks of my first kids robotic camp here in Calpe - Alicante - Spain.

    17 kids from 6 years to 13 are starting in robotics, sketching, programming, 3D printing and 3D modeling here in Calpe.

    With Emme Technology is not complicated

  • After a very intersting Kickstarter Campaing I have only 5 pledges

    Salvador Hurtado Alia07/22/2017 at 20:00 0 comments

    Hi World, 

    Really I learn about Emme possibilities with my first Kickstarter Campaign with Emme, I need new solutions for lower the cost to have a Ready to Run Project for less than 100 bucks.

    Thanks for the 4 people who bought a Maker License now I know sell Maker License with Manuals, videos, bill list to help makers to have their own custom Emme is possible.

    Thanks too for the baker who bought a ready to run option for the Off Road Model.

    Some Foundations are interested in using Emme at educational projects and now I´m thinking about the pedagogic support materials, at the same time teaching in Robotics Kids Camp here in Calp, Spain it's helping me to open more my mind, Really its very interesting teach kids from 6 to 13 years old 3 hours a day at the same time in organics teams.

    Let's go, I am on the Road!!!

  • Designing the new electronics to use ESP32 from Espressif

    Salvador Hurtado Alia07/22/2017 at 19:51 0 comments

    Now after the end of the Kickstarter Campaign last July I have more time to prepare the new Electronics,

    I love the new ESP32 and its low cost at high quality is perfect for Emme, I´m designing a new PCB board where "click" the ESP32-DevKitC. 

    My actual prototypes use the Adafruit Feather M0 WiFi - ATSAMD21 + ATWINC1500, this module is a piece of cake for the firsts prototypes but for lower the cost and to have BLE and more power I really like the Espressif option.

    These new board it's going to include BLCD controller, RGB LEDs, lipo charger and much more.

    Thanks once more to Esppressif who help me with their Support at the technical part and with his newsletter about Emme.

  • Kickstater select Emme as Project we love

    Salvador Hurtado Alia07/22/2017 at 19:38 0 comments

    Hi, last 1 of June after some hours after launch the Kickstarter campaign Emme was selected as project we love.

    A lot of to think, Emme is a perfect ambassador of a new path to design Technology, but I need to work a lot to evolution its parts and components to lower the 3D printing time and the cost of the motors and electronics. 

    Emme Ready to Run versión must be between $90 and $120, and I need to study how to share with free cost the maker's license for a private use.

    Now I´m redesigning the electronics to use the new ESP32 from Espressif.


    God for the opportunity and for your help in every moment

Hi Radomir, here you have the first six weeks of the design of the robot, perhaps the videos, photos and the sketches can introduce you a more information about the path of my design, I start the project as a personal challenge and publish everyday information on a Facebook page:

Perhaps you could put some more descriptions of this fabled "new form" of design, and not just marketing crap in here?

  Are you sure? yes | no
