Last year Jaime Hayon played chess in Trafalgar Square, but this year at the London Design Festival, Clemens Weisshaar and Reed Kram are bringing massive robots.

From September the 16th to the 23rd, their project entitled 'Outrace' will empower the general public to take control of eight industrial robots on loan from Audi's production line. Essentially, the 'Outrace' project is a popup factory: a temporary production facility for writing large scale messages with light in three dimensions.

And the experience is not just confined to visitors to the square; a global web audience will be able to interact with the installation via their website (below).

By attaching light heads onto synchronized mechanical tentacles equipped with LED technology from the the Audi R15 race car (winner of this year’s 24h of LeMans no less), the installation ingeniously allows users to transcribe light trace messages into the air in real time.

As users write their messages, each unique light trace will be simultaneously recorded and uploaded to the web through a system of high definition cameras.

Here's what Kram and Weisshaar have to say:

"While industrial robots appear to be implausible machines, pulled from the pages of a science fiction novel, they are in fact ubiquitous throughout high tech production facilities.

Removed from their everyday context behind factory walls and taken onto a trip to London's most public square they become mighty ambassadors from a foreign land within our midst that produces the goods we use and the cars we drive."

Ever felt the urge to write a message to your loved one/Mum/boss with a 1200kg robot arm?
