Designers consider letting robots communicate with humans with their tails

The appearance of the robot looks cold and cold, and it is cold and cold in the heart. It has no emotions, no feelings. However, in some cases, humans also want to know the state of the robot, such as whether it has failed or not. Undergraduate Ashish Singh of Manitoba University and his mentor James E. Young investigates whether the tail can be used to help humans accurately interpret the "feelings" of robots, just like dogs.

For example, happiness means that everything is normal, sadness indicates a problem, and exhaustion means that there is no electricity. Professor Young said that human beings are social animals and are very experienced in quickly reading emotional states. They considered a variety of options and eventually chose to investigate a dog-like scheme because even people who don't have dogs or cats can interpret information based on tail movements.

Based on the results of the research, the researchers developed a set of tail movement rules for communication. For example, if you want to express it “overwhelmed”, you can try high-speed loop swing. From awe to shame to happiness to surprise, there is a specific tail movement.
