Survey after survey has shown a lack of women engaged in science, technology, engineering and mathematics (STEM) fields. It's an utterly human problem, but one group of eighth-grade girls recently experimented with a way to address at least one aspect of it -- with robots. The students, participating in a program funded by the National Science Foundation (NSF) called Co-Robots for CompuGirls, programmed a pair of two-foot, identical humanoid "Nao" robot avatars to help with the process of interviewing for a STEM position.
