According to experts, robots must become friendlier if they want to gain people's trust.

A new study shows that almost all types of robots still score poorly with humans when it comes to comfort. The study by AI software company Myplanet found that drones and humanoid robots were among people’s pet peeves. Manufacturers need to work harder to combat this robot bias.

“One of the first and most pervasive trends we noticed in our research was a strong aversion to technology that tries to be too ‘human,’” said Jason Cottrell, founder and CEO of Myplanet, in an email interview.

“Robots that look like humans, chatbots or voice assistants that communicate too naturally with each other, or even placing robots in roles that rely too heavily on what we generally consider human traits, such as empathy, are all frowned upon by consumers.”
