The jib works with a remote-control pan/tilt head that uses heavy-duty RC servos attached to external gear boxes. Both servos are modified to rotate continuously. The pan-tilt head can be supported from below or hung from above (the jib supports both options). To use the hanging mode without flipping the camera, the tilt module can be rotated 180 degrees.

The camera attaches using a custom mounting plate. Future camera rigs can use the same mounting system, so that the camera can quickly be moved from one device to another.

The jib can ride on a dolly I built in 2006. This dolly works with standard dolly track, including curved track.

The video is here (low quality version).

I created software and electronics for several parts of the installation. A train interior and bedroom interior both had video windows that could be switched between day/night and country/city. A car had a projected background, also switchable between day/night and country/city, with the playback speed and volume controlled by a gas pedal (a hacked guitar pedal).

Two units had video backgrounds that moved in syncrhonization with hand-cranked miniature foregrounds. I created wooden optical encoder wheels to measure the rotation. The structural and mechanical parts (along with all of the other sets) were created by Tim Rossiter.

After being installed in New York, the installation traveled to Sao Paolo and Rio.

The video was shot using hundreds of cameras, mostly wielded by audience members (mostly using cameras brought be the audience members). Tapes were distributed at the start of the show, people were assigned locations to stand, and tapes were collected at the end of the show.

Within hours of the show ending, we began around-the-clock tape transfers, using 7 computers and 8 cameras (see photos below). The transferring finished ahead of schedule, in about 24 hours, producing a couple terabytes of data.

Then we began processing the data. Olivier worked on one copy of the data while I worked on another copy. We each wrote custom software to align and edit the footage.

I used a Mini-ITX computer with custom software (using the portaudio library) to play the audio samples. Key presses were detected by a pair of Arduinos. One Arduino was used simply to multiplex the other Arduino’s I/O lines.

The software included a recording mode, so that Os Gemeos could record each sample using the organ keyboard and a microphone. For some samples, they played songs from a laptop attached to external speakers, which were then recorded using the organ’s software/microphone (a nice digital to analog to digital process).

The work was subsequently installed as part of The Margulies Collection in Miami.

The robot planted seeds and recorded videos/photos of the plants growing. The robot used a set of attachments: soil moving, seed distributing, watering, and lighting.

Structural / Mechanical Design

• The motors are 12-24V DC with worm gears.
• Connecting structures are lasercut 1/8″ MDF, layered with wood glue to form 1/4″ rigid parts.
• All other mechanical and structural parts are from McMaster.
• Motor adapters reduce from 5/16″ (motor) to 1/4″ (shaft) using 5/16″ shaft couplers and 5/16″ OD / 1/4″ ID bushings.
• Shafts are 1/4″ steel.
• Bearings are 1/4″ ID, flanged and shielded.
• Horizontal rails are lined with 0.08″ pitch timing belt, matched with 48-tooth and 60-tooth timing belt pulleys.
• Vertical mechanisms use 25-pitch roller chain and sprockets.
• Primary structural elements are 1″ x 1″ square steel and aluminum tubes.
• Mounting hardware is predominantly 1/4-20 bolts.

Electronics / Software Design

• The attachment modules are provided with 120VAC (relay controlled), 24VDC (relay controlled), 5VDC (relay controlled), a 5VDC servo signal, and ground.
• Each limit switch is an IR interrupter attached to a breakout board.
• Motors are driven using an L298 kit.
• Digital and analog inputs/outputs connect to Arduinos via a proto shield.
• The Arduinos communicates with a computer via USB.
• The user interface software is implemented in C++ using the FOX Toolkit.
