Scientists build robot rat to instill fear, depression in hearts of real rodents | The Verge.

“Scientists developed the mechanical rat to attack and intimidate living, breathing rats. It does this to stir depression in the rodents, which in turn allows experts to test antidepressants and other drugs potentially destined for human consumption. Researchers at Tokyo’s Waseda University have found that assaulting the rats physically leads them to enter depression quicker than other methods; those include forced swimming and electrocution. But those tactics pale in comparison to the fear and anxiety that the robot rat can cause.”
