Follow me, I know the way

LABrador is a device created to give visual disbale people an opportunity to navigate trough space, created as an stick assitance.

When we talk about smart cities we can imagine more effcient and ecofriendly environment, but what about creating a more inclusive atmosphere for people with any kind of disabilities, this is actually what would leads us to the future.

How does LABrador works?

We decided to create a really intuitive gadget that could lead people with visual disabilities to go from their point A to a point B, the aim was to connect the device to plattform or a navigation system, this will turn labrador into a device which through it’s outputs give a response (sensorial one) to the user to follow simple directions to find the better route, as it was said before LABrador is an assitance for the blind stick, this mean that with the combination of the stick and LABrador , the user could navigate in any place giving the opportunity to move freely, and have the chance to explore the city with any trouble.


The future for LABrador
for the feature of this device Cinco Team consider to create a smart device with voice inputs and multisensorial outputs such as a vibritation language and a speaker. Also an ultrasonic system is consider in order to sustitute the stick.

By the time Cinco Team was thinking about the develop of labrador , we consider serveral ideas which could satisfice our needs.
We came with the idea of creating a bracelet that could guide the user through the use of sensorial outputs (vibrations).

The first prototype was consider as a bracelet because we consider it could be really practical and convenient. Having a bracelet could be the answer because it is a really ergonomic shape that could fit anyone.

First we model the prototype on Rhinoceros to have an idea of what we were going to 3D print after .

Some difficulties were found by the time of bringing this model to the fisical world, for example the was not that much space for vibromotors and all the hardware LABrador needed.

For the hardware part of the device we used this components:

  • Arduino Uno (testing part)
  • Arduino Nano
  • HC-06 Bluetooth
  • cylindircal Vibromotors
  • round vibromotors
  • wires

As we faced several issues with this prototype shape, we decided to explore new materials, such as silicone.

This was the point when we realized we had to explore not with different material but with different shape in order to fit all the hardware.

Programing Arduino.

For his task we used the arduino software to help us to program our motherboards.
For this task we use the help from some youtube tutorials which we found so practicals and useful for our device, i will leave the links for you to check them out:

To make vibromotors worked we needed to create an app for phone, we used as reference the youtube links we have already post before, to create the app we use app Inventor.

It was time to test the motors

Moving on we arrived to our last and final prototype, the stick assistant.

We devided the third prototype into two part, on the first stage we explore making a soft grip in order to explore space and texture of the device.

On the second stage we manage to create a new 3D model where everything could fit in . To get to this model with experiment with shape and hand grips which we overlap to create the more suitable shape of labrador, for this task we used clay.
For this stage we desing the first model which was split on half to make it easy to work with and also we incorporate some clippers to open and close the case, at the end we changed it because it was not really convinient for the 3D printer .

Last model was the more suitable for our needs and we manage to fit everything in.

An exploration on lighting and communication

Audio: Sordid Affair-Royksopp

Project description:

In order to increase the capacity of city inhabitants to interact with their social and digital environment we decided to create a lighting device which could allow the user to transmit individual and collective lighting patterns that can be transfromed into messages, screens and atmospheres. By this mean of communication, individuals become able to increase their communication tools and to customize their visual experience in the city. Hardware:

Cutting
-Lasser cutting machine

Lighting:
-Arduino (Nano and UNO)
-Smart Led’s
-Soldering iron

Software:
-Autocad
-Arduino
-Android programming

Materials:
-Tyvek buy it here
-Polypropylene
-Velcro
-Polyethylene

Brainstorm:
From the beginning of the project, most of our ideas were related to the textile, energetic and lighting industry in relation to the body. Taking this into account, we decided to explore the possible scenarios and social purposes where these technologies could have a significant impact in the city.

Process

At the beginning we experimented dismantling lamps and reconnecting their components to make it work with solar energy.

In the second step we addressed the energy issue including a peltier device to the systhem using Arduino and a battery:

a solar pannel conected to a peltier to a battery to Led’s

In parallel we started exploring possibilities to create a modular lightweight surface.

And we merged paper and lighting to explore the possibilities of unifying the information layer from lighting with the spatial possibility of paper.

When we managed to develop this technology we where searching to give a purpose to it and we started to explore the possibility to wear it.

From that moment we decided to continue only with the wearing device and we created the Social Pixel

Midterm:

By then, we improved the physical design and the electronic components to make the pixel able to communicate with cellphones thru an app.
