According to a latest research, the Japanese robot researchers have discovered the secret behind the perfect gate of the entertainers like Elvis Presley and Miley Cyrus.

And on the basis of their study they have come to a conclusion that the secret lies in the hips.

The researchers wanted their robots to look more real and natural and for this reason they studied that how Elvis "The Pelvis" made his way to 1950s fame and one-time child star Cyrus gained instant internet fame with her `twerking'.

Twerking is a type of dancing in which the dancer, usually a woman, shakes her hips in an up-and-down in bouncing motion, causing the dancer's buttocks to shake as well as wobble and jiggle.

The researchers at Waseda University's Humanoid Robotics Institute near Tokyo tried to copy the way the waist was used in humans into their new robots. This was done by spending hours for analyzing that how the waist is useful to give humans their easy gate.

The new robots of the team of the researchers have flexible hips. Also, each leg of the robot can be rotated. The robots also mimic the style of walking of human being.

Assistant professor Kenji Hashimoto said, "Most humanoid robots don't have waist motions... so must bend their knees, giving them an awkward and stilted walk".
