Art goes mechatronic

Art goes mechatronic With clear conditions, if you're one of the 48 million or so passengers that will fly in or out of Heathrow airport between February and September this year, you'll be treated to an amazing digital light display emanating from the Watermans Gallery in London. The display is a creation by the French artist Felicie d'Estienne d'Orves and marks the start of Watermans' International Festival of Digital Art. The London 2012 Olympic and Paralympic Games have inspired the Festival of ground-breaking installations, exploring interactivity and participation in new media and digital art.

The work of six international artists will be showcased in a year long project that is designed to initiate debate around the impact of technology in art. The light display of Felicie d'Estienne d'Orves, known simply as Geometry, is a kinetic installation driving two masts that cross (one vertically and one horizontally), on which mirrors are attached. The pre-programmed mirrors turn on a horizontal axis creating geometrical movement. The reflection of the sky in the mirrored blades and the movement of the sculpture itself create different kinetic effects according to the time of day and the season.

At nightfall the signal is reinforced through projections of laser light from the horizontal mast. Laser lines will be projected from the Watermans building onto the horizontal mast and reflected from the sky. The programming of the movement of the sculpture means that geometrical forms are created and reach into the sky to a height of more than 20 metres.

Bonfiglioli is one of the world leaders in providing mechatronic solutions to a wide variety of drive and power transmission challenges and was chosen to provide the technological support behind the installation, working closely with the artist and David Simpson of Show Laser Systems. Bonfiglioli received initial contact concerning the project on December 13th 2011. The expertise of the company in assisting with unusual applications was a key factor. Bonfiglioli's mechatronic approach and ability to supply all requirements from one source was also important. On 16 December all parties met and the project details and technical specification were confirmed. The inauguration ceremony for the Festival was booked for 2 February, so there was a very tight completion date.

In order to achieve the variety of mirror positions designated by the artist a very precise positioning motor solution was required with a complex programme for the inverters. The installation utilised two shaft mounted helical gearboxes from the Bonfiglioli F Series. The gearboxes are driven by direct coupled brushless servomotors fitted with failsafe brakes. The drives are an external arrangement open to the elements. Consequently they are protected to IP65.

The Bonfiglioli Active Cube inverters that control the drives are located in a specially prepared cabinet, and programming was made simple due to the plug and play capability. The inverters are easily capable of handling the complex programming sequence necessary to enable the numerous changes of rotational direction to give the desired effect. In addition, the drives had to be capable of achieving the 24 exact position co-ordinates required, as well as precisely controlling the eight desynchronisation points of the two reflectors. Close collaboration with the laser architect and the artist was necessary to ensure the final programme produced the desired effect. Bonfiglioli engineers were on hand during the final commissioning, to ensure that the vision of the artist and the architect became a reality, by deploying precisely matched drive components to produce a repeatable and reliable solution.

The Geometry project has been made possible with a grant from the Mayor of London's Outer London Fund and is supported by the London Borough of Hounslow. Mayor of London Boris Johnson opened the installation that will run until the end of September 2012.
