Robots With Sweaty, Smelly, Hairy Armpits to Alert You When Danger is at Hand

A British designer has invented a robotic armpit complete with hair and a synthetic sweat gland that emit an odour designed to trigger sub-conscious responses in humans.

"I chose the armpit because I was interested in using smell as a communication tool in human-robot interaction," News.com.au quoted Kevin Grennan as saying.

Robotic Suit Which Gives Wearer Strength Of Ten Men!
A Japanese man paralysed from the waist down is looking forward to climbing a mountain with the help of a man in a cutting-edge robotic suit, which boosts the wearer's strength tenfold.

"Other researchers have been developing faces, hands etc ... (but) our sense of smell is much more subtle than our other senses and our reactions are sometimes sub-conscious.

Grennan specifically designed the smelly robotic armpit for a bomb disposal robot.

As it goes about its work, the robot literally begins sweating, filling the air with the same kinds of chemicals produced by humans when they're afraid.

Showa Hanko 2, a very life-like robotic doll will make a world of difference to the practical training offered for dentists.

The designer said experiments show that such fear triggers have the potential to enhance a human's cognitive performance.

"This robot would enable surrounding humans to work more effectively and to differentiate dangerous situations from false alarms," Grennan explained.

Researchers Work on Developing Sensitive Skin for Robots
Scientists are developing a synthetic skin for robots which will enable vital communication palpable through touch.

He also has concepts for a picker robot and a surgical robot. The armpit and its unpleasant aromas serve different functions according to the purpose of the robot.

"In the case of the picker robot, (the armpit) releases a chemical called androstadienone, which is found in male sweat," the designer said.

Underwater Robot Discovers New Corals In Great Barrier Reef
A high-tech underwater robot has discovered diverse coral reef communities living in the unexplored deep waters along the Great Barrier Reef shelf-edge.

"This has be shown in research to affect mood in females under certain circumstances.

"I have speculated that this robot, when used on a production line, could enhance the performance of female employees in its vicinity," he said.

The third robot is a surgery robot that releases a mist of oxytocin, a chemical found in the human brain.

"This chemical when inhaled nasally has been shown to cause people to become more trusting," Grennan added.
