The Japanese practice of drawing patterns in sand, known as “karesansui” or “dry landscape” gardening, is often associated with Zen Buddhism. These gardens are designed to embody a sense of ...

Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials -- artificially engineered composite materials that derive their properties from patterned ...

Simplified machine designs with fewer components run more efficiently and are less expensive to build. Older mechanical power transmission and actuator technologies, such as chain, rack and pinion and ...

WASHINGTON — Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials onto paper. They demonstrated the new approach by using it to make three ...
