Based on some previous work we’ve done with megaphones in public spaces, me and my associate, Radamés Ajna, were invited to participate in an exhibition called Multitude, curated by Lucas Bambozzi and Andrea Caruso Saturnino.

The exhibition was based on the writings of Antonio Negri and Michael Hardt and their concept of multitude, and focused on works that address forms of resistance to established power and pre-established channels of legitimization, while thinking of the crowd as a set of singularities and unique identities that affect each other in a process that combines power, but also dissent.

We proposed to build a set of robotic sculptures that would allow visitors to participate in the exhibition by sharing their opinions using a system that would turn anonymous sms text messages into voice.

Paso 1: Inspiration

The project is also inspired by the public demonstrations and protests that happened throughout Brazil in 2013, and the government's attempt to regulate the use of public spaces.

Specifically, it plays with the ambiguities that arise when trying to define social behavior in dense urban areas, where everyday activities are already violent and chaotic.

In order to convey some of this ambiguity and violence we decided to make our megaphones look like weapons that could be aimed and used to "attack" certain parts of the exhibition space.

<p>Awesome project, looking forward to Version 2 ;-)</p>
Muito bom meu amigo, pode controlar as posi&ccedil;&otilde;es? dele? ou somente giro completo?
<p>Ol&aacute; !<br><br>Nessa vers&atilde;o estamos usando motores DC normais com uma chaves de fim-de-curso para evitar giros completos. Conseguimos programar eles para apontarem em certas dire&ccedil;&otilde;es gen&eacute;ricas, sem muita precis&atilde;o, usando umas rotinas pr&eacute;-programadas.<br></p><p>Mas, n&atilde;o, nessa vers&atilde;o n&atilde;o tem motor de passo. Ficamos meio preocupados com o custo de motores de passo para mover o peso da caixa inteira. Estava pesando uns 5kg no final.<br><br>Outra op&ccedil;&atilde;o era usar um m&oacute;dulo de b&uacute;ssola e girosc&oacute;pio para ter algum controle do posicionamento com esses motores baratos.<br><br>Abra&ccedil;o.</p>
<p>Very nice design, well thought out, excellent build!</p><p>just curious...why didn't you internalize all the gizmo's and wires?</p><p>What would it take to mount a camera inside of the megaphone so you could see who you were shouting at?</p><p>Also the other inspiration that struck me was 1984.....</p><p><img src="http://ts1.mm.bing.net/th?&id=HN.608047995041481605&w=300&h=300&c=0&pid=1.9&rs=0&p=0" style="width: 205.0px;height: 300.0px;"></p>
<p>Hello ! <br>In the final version we did hide all the wires and the circuitry inside the plastic cover.<br><br>Some of the videos/images that show the guts of the thing were made during the debugging and assembly stage : )</p><p>Yes! Hanging a camera on it and having it track people wouldn't be too hard. We experimented with the Raspberry Pi camera module and it worked pretty great. We just didn't have the time to implement some kind of detection and following code.<br><br>Next time!<br></p>
<p>Cool, I like all the thought behind this project.</p>
