It’s hard enough to make a functional, reliable robot. Many people also want to make those robots in our image. That’s a tough needle to thread. Often, the most efficient design isn’t the most human-like one. But that isn’t stopping us from reaching for those humanoid robots. Professor Shigeki Sugano argues in favor of creating human-shaped robots. But it’s such an enduring challenge, we’ve come up with a name for it: the uncanny valley. Evan Ackerman walks us through the uncanny valley’s treacherous terrain. Deanna Dezern shares how she’s connected to her robot companion. And Dor Skuler explains how he deliberately avoided making his robots look like humans.
