The robot in the picture above chases and attacks the living rat rights besides it. The W-3, as the robot is named, is designed to make rats seriously depressed. In fact, this robot is one of the best methods to induce depression in lab rats.
Making a rat depressed might seem strange or even unethical, but researchers have already done it for years. After all, you can’t develop antidepressants without having depressed rats to test them on. Current methods to make rats depressed, like making them swim for hours or giving them electric shocks, do not quite mimic the day-to-day situations humans go through. Therefore, the researchers at Tokyo’s Waseda University developed a robot that more precisely mimics the social stressors that can trigger depression in humans.
I wonder how a depression-inducing robot for humans might look.
