Scientists at Arizona State University (ASU) have redesigned a robot used by apparel companies for sports equipment to mimic the thermal functions of the human body.
The world's first walking pygmy that generates heat, shivering, walking and breathing like a human could help scientists understand our bodies' resilience to heat waves.
The ANDI experimental robot is equipped with artificial pores for artificial sweating and heat generation and heat flow sensors across 35 different surfaces covering the body of the humanoid anthropomorphic body.
With a new internal cooling duct, the improved ASU ANDI is the first thermal dwarf object suitable for outdoor use - meaning scientists can now subject it to the extreme temperatures of the Arizona desert without fear.
"You can't put humans in high-risk locations from the heat and see what happens," said atmospheric scientist Jenny Fanos, an associate professor in the ASU College of Sustainability. "But there are locations in the Valley where people are dying from the heat, and we still don't quite understand what's going on." happened. Here ANDI can help us figure it out."
"We don't want to do a lot of these [tests] on a real person. It's unethical and it would be dangerous," said Professor Konrad Rekajewski of Arizona State University.
'The world's most advanced robot' describes 'terrifying nightmare scenario of artificial intelligence'
"A diabetic patient has different thermoregulation than a healthy person," according to ASU research scientist Ankit Joshi, who is leading the modeling work that goes into ANDI.
A warm room can also be modified to simulate different heat exposure scenarios common to any hot spot around the world. But it's outside in the heat of the desert Southwest where ASU modded ANDI faces his toughest challenges and his biggest work.
The thermal troll can sweat, with dedicated internal cooling ducts to circulate cool water throughout its body, while simulating and recording human reactions to heat from complex environments.
ANDI sensors collect unique data on the interaction of body type with solar radiation from the sun, infrared radiation emitted from the warm asphalt earth, and convection diffusing in the air. When the ASU team covered ANDI with a special fabric, his simulated sweat wicked to cool the sensor-laden robotic surfaces, just as if he were a real human.
ANDI will team up with a new partner: the MaRTy biometeorological thermal robot, a set of complex temperature sensors mounted on a vehicle.
