A Drawing Machine Whose Pen Strokes Become Pixels [Video]
The polar coordinate system gives Noble's artwork a unique look that's robotically geometric but messily organic at the same time. "A Cartesian system is what most maps use -- four cardinal directions, two perpendicular to the other two," Noble tells Co.Design. (X and Y values are also Cartesian.) "But if you imagine a map of the Arctic, then you'll see that 'north' doesn't really mean anything: All the top ends of the lines of longitude are collapsed into one point."
Noble uses the top two edges of his canvas as "poles," with "pixels" radiating out in an overlapping pattern of arcs. "The angle of the lines and the fact it's all made up of subtle curves gives the impression of hand-drawn-ness," he says. "Close up the lines are rather beautiful too, precise and even, and always on this subtle curve. It really clearly is machine-made, but it doesn't seem to have the square-edged monotony that might be expected. When there is a bit of movement in the pen tip too, then new effects appear, the quality of the hatching pattern degrades, usually in an attractive way and it evokes stitching or embroidery."
The machine is programmed to parse a bitmapped image into polar coordinates, which the robot mechanism executes. But Noble set it up purposely so that he'd never know quite how each drawing will turn out. "The software gives me a crude preview of how the image has been converted into blobs of density," he says. "So I get a rough idea of what details will be visible, and what details won't, but calibrating the pen thickness adds another dimension of unpredictability, so until it starts drawing I really don't know how dark the darkest bits will be, or how smooth the gradients will be. Or how long the pen will last!"
Noble has already exhibited his polargraphs in a gallery, and has "a couple of commissions lined up." If you like these, you might want to hit Noble up for one before he makes the transformation from agreeable engineer to art-world diva. (Don't ever change, Sandy!)

's Co.Design. Here, we try to bridge the fuzzy border between design and business. We started this site with a few simple premises in mind. First, design is a window onto the world at large, and the culture we live in. When a designer sets down to make something new, she can't help but have some idea about how some object could be so much better than ever before...Polar Coordinate System - News

Our latest find comes courtesy of Sandy Noble, an artist/hacker who created a primitive robot that sketches out pixilated images in long, arcing motions based on a polar coordinate system. He calls these works, appropriately, "polargraphs.

The level of automation in the manufacturing industry constantly improve range of applications is expanding. Packaging industry, automation is changing the way the packaging process and packaging of container movements and materials processing methods. To achieve automatic control of the packaging system can greatly improve production efficiency and product quality, significant elimination of packaging and printing processes such as a result of labeling errors, effectively reducing the labor intensity and reduce energy and resource consumption.
Revolutionary change in the packaging automated manufacturing methods and its products transport. Design and installation of automatic packaging systems, in terms of improving product quality and production efficiency, or from the elimination of processing errors and reduce labor intensity, have shown a very significant role. Particularly for food, beverage, pharmaceuticals, electronics and other industries, is essential. Automatic devices and systems engineering aspects of the technology is further deepened, and be more widely used.
Robotics (Robotics) has changed the way man-machine co-existence. The key basis for automatic packaging production, processing or packaging processes, to design a structure can be realized automation program. Clearly, the automatic devices (mechanical hands or robots) the choice depends on the needs and characteristics of this process. By definition, an automatic device that is through the automatic or remote control method to complete the task of a machine or an institution. It can be simple, for example, move from one location to another location of the structure of a single-axis pneumatic pressure linkage device; it can be complex, for example, has a six-axis structure of the dynamic surgical robots. The packaging process of the various project selection and a variety of industrial automation sector, in a specific space within the workplace so that each design to complete a task. At present, the automatic device of the structure type is varied. For example, to meet the needs of a particular operation. Industrial machinery are in the hands of the structural characteristics of single-axis and 6 axis. According to this axis structure, performance, mechanical hand, “arm” design in motion control procedures, operating an end operation or the arm-side tools. Axis represents the number of robotic arm’s “freedom.” In addition, there are auxiliary arm. For example, the conveyor shaft and so on, but they are usually not by mechanical means and the robot is linked to the main arm. For different robot forms, are generally based on its “x”, “y”, “z” coordinate system composed of three main axis to classification. Most of the mechanical part of the following five basic types of ~: Cartesian or rectangular coordinate system, cylindrical coordinate system, rotating, or hinged coordinate system, spherical or polar coordinate system and the election workers Combined soft robot (SCARA).
