Underwater robot designed to search inside shipwrecks

Engineers from Estonia have developed a new robot "turtle" called U-CAT that was specially designed to navigate inside underwater shipwrecks. U-CAT’s locomotion principle is similar to sea turtles. Independently driven four flippers make the robot highly maneuverable; it can swim forward and backward, up and down and turn on spot in

Mysterious spheres found in ancient temple

Hundreds of spheres have been found beneath the Temple of the Feathered Serpent at Teotihuacan in Mexico. The mysterious spheres lay in both the north and south chambers. Ranging from 1.5 to 5 inches, the objects have a core of clay and are covered with a yellow material called jarosite. "This material

Archaeologists are planning to use a robot to assist them in exploring a tunnel found underneath the Temple of the Feathered Serpent at Teotihuacan. The tunnel, discovered under the Temple of the Plumed Serpent, or Quetzalcoatl, is believed to lead to a chamber almost 2,000 years old, probably a place where

Underwater robots used to search for Minoan shipwrecks

Robot used to explore Teotihuacan tunnel

A robot has been used to explore a 2,000-year-old tunnel found underneath a temple at Teotihuacan in Mexico. Archaeologists lowered the remote-controlled, camera-equipped vehicle into the 12-foot-wide (4-meter) corridor and sent wheeling through it to see if it was safe for researchers to enter. The one-foot (30-cm) wide robot was

Robot to explore Great Pyramid tunnels

A robot is about to go where no man has gone in the last 4,500 years: into the shafts of the Great Pryamid at Giza. No one knows what the shafts are for. In 1992, a camera sent up the shaft leading from the south wall of the Queen's Chamber

Voice of Disneyland’s robotic Lincoln takes criticism

The robotic Abraham Lincoln at Disneyland has received a technological overhaul, but his voice has remained the same...and incorrect. Instead, Disney dusted off and remastered the original 40-plus-year audio recordings made by character actor Royal Dano.
