How Do I Smell, Robot?


Technology companies are making great strides in odor-detection robots, valuable in identifying subtle scents ranging from contaminants in beer brewing to cancerous tumors in the body. And then there's CrazyLabo in Fukuoka, Japan, marketing two personal-hygiene robots, available for special occasions such as parties, according to a May BBC News report. One detector, shaped as a woman's kissable head, tests breath odor and responds (e.g., "smells like citrus"; "there's an emergency taking place"). The other, resembling a dog, checks a person's feet and can either cuddle up to the subject (no odor) or appear to pass out.
