At just under two feet long and 15 inches wide and tall, the BeachBot can autonomously fill a 30-square-foot area of sand with images from the "Lion King" or "Finding Nemo" in under 10 minutes. Seven servo motors allow the bot to deploy the prongs of its rake in different configurations, creating varied brush strokes that range from two to 15 inches wide. Bulbous balloon wheels make it possible for the 'bot to traverse all types of sand while leaving no tracks that would mar the drawings.
The BeachBot does have some limitations. Reflective poles must be placed on the beach by humans to define the canvas the robot draws on. Fine motor controls don't mix well with sand and salty surf, so in addition to building rubberized seals into the design to protect the sensitive internal workings from the elements, extra care is required in maintenance.
The project grew out of the lab of Paul Beardsley
, a principal research scientist at Disney Research Zurich
. Beardsley specializes in making robots with theatrical qualities, like his swarming Pixelbot
drones that can arrange themselves into displays of characters on any flat surface.
"Disney has had a fundamental role in the development of two forms of entertainment -- full-length animated movies and theme parks," says Beardsley. "No-one can predict exactly what might arise as new forms of entertainment in the future. But it's certain that society is just at the start of a robot revolution, and my work is in developing new types of entertainment robots."
There's been no announcement of when this beachcombing robot will make its public debut, but rest assured that once it does the sandy sections of Disney's theme parks, its Aulani resort in Hawaii, and the ports of call for their cruise lines will be blanketed with sandy sketches.
And for fans who prefer "Frozen" to "Finding Nemo," a winter edition is in progress. "We are working on different modules for the BeachBot to take it off beaches and into other situations," says Beardsley. "Snowy fields are a possibility, pretty good for Switzerland at least."
