TEXT 1

When the World Trade Center towers were destroyed in 2001, engineers deployed a handful of lightweight bots to burrow through the rubble.The robots, roughly the size of shoe boxes, offered a new way for rescue teams to take a look. A few tunneled deep within the wreckage and withstood extreme heat to find 10 sets of human remains. But the robots didn’t locate any survivors.

A smaller robot, designed for disposing of explosives, was the first to enter Fukushima’s reactors, about a month after the disaster. Small and light enough to be carried on a soldier’s back, the robot, called the PackBot, uses treads to haul itself over bumpy turf. A thin arm mounted with a gripper claw and a camera lets the robot grasp and see. In the days following the Fukushima earthquake, iRobot, the Massachusetts company that produces the PackBot, rushed to add radiation and chemical sensor s to the bots.

The sensors came in handy: Plant workers used them to find places inside the plant where humans could safely explore. But maneuvering the robots through the darkened plant was at times impossible. Though the machines could open doors, the bots’ operators had to use two PackBots to do so: one to turn the handle and the second to aim its camera at the first. What’s more, the robots struggled to climb the plant’s slick metal stairs.

OceanOne, a robot avatar lets humans explore deep under the Ocean's surface, without any of the dangers or time limits associated with diving.

While a human diver is constrained by annoying things like air and pressure when doing underwater research or excavations, a robot can stay underwater for much longer, collecting samples in hostile underwater environments.Unlike submarines, which have limited ability to take delicate samples, and have tools that require extensive training to use, OceanOne is controlled by haptic joysticks, letting its operators feel the lightness or heaviness of whatever object it's holding, thus giving researchers a much more hands-on feel.

 

Schilling Robotics system combines a remote operated vehicle with thrusters for maneuvering and two robot arms for manipulating. One of the arms can grab something rigid, such as the base of an oil rig, to steady the vehicle while the other arm performs such tasks as welding and valve maintenance.

 

The Australian Centre for Field Robotics at the University of Sydney developed a prototype for autonomous underwater robots that may one day explore and monitor the Great Barrier Reef. At present this robot (called Oberon) must remain tethered (=connected) to a ship on the surface, but within a decade it would be possible for robots to be lowered to the ocean floor and left to get on with mapping the terrain on their own. Oberon has two scanning sonarsand a depth sensor as well as a color camera. It does not need any independent information, such as from GPS satellites, to work out where it is.

VENUS IS NOT pleasant. Its surface, approximately 850 degrees Fahrenheit, is hot enough for paper to spontaneously combust. Its atmosphere, an oppressive mix of carbon dioxide, nitrogen, and sulfur dioxide, is dense enough to crush a submarine.

The last time a bot visited the surface of Venus was in the mid-80s, when the Soviet Union sent its Vega lander to capture data about the planet’s soil. It lasted for less than an hour.

The key to the rover’s longevity?Keeping it decidedly low-tech. The concept rover, called AREE (Automation Rover For Extreme Environments), is a great example of counterintuitive problem solving. Instead of packing high-tech electronics into its frame, the scientists are building a mechanical rover that works with minimal electronics. The boxy, tank-like bot rolls around ontreads, making it resistant to Venus’ rough terrain. Those treads are powered via a wind turbine that capture s the planet’s winds and stores that power inside springs before distributing to the various systems on the rover.

Unlike an image-based navigation system like the Curiosity rover, AREE's treads can withstand unexpected drops and bumps. And instead of relying on a two-way radio to communicate data, the Venus rover will use a simple optical reflector to transmit its data to orbiting satellites by flashing radar light like Morse code. It’s not an information-dense system (AREE is projected to transmit 1,000 bits per day, compared to Curiosity’s 1 million bits). But by sacrificing smarts for sturdiness, NASA is betting a rover like AREE will last longer and travel further than more advanced rovers.

Anna Konnda is a water-powered hydraulic robot snake. It is driven by twenty custom-built water hydraulic cylinders. The snake measures 3 meters long and weighs 75 kilograms. The control of this robot is realized using numerous microprocessors that control the joints. The main controller can be connected to a PC via a Bluetooth connection.

Developed by Hoya Robot Company and financed by the South Korean government, this robot is intended to be used by firefighters as their personal spy. Despite its heavy armor and robust look, it measures only 12.5 centimeters in diameter and weighs 2 kilograms.

This robotic device can be thrown into a building on fire and operate there for 30 minutes. As it can withstand temperatures up to 320F (160C), firefighters can explore the environment and plan their actions accordingly using this remote controlled robot.

 

The Firemote, designed by Ryland Research Limited, is also among firefighting robots that weigh around 450 kilograms. This robot is also remote controlled (up to 300 meters); it can withstand high temperatures as well as extinguish fire using either water or foam. In addition to these "basic" capabilities there are also some quite unique ones.

Battery compartments are changeable thus allowing changing batteries instead of charging them. The robot is also equipped with four color cameras that together provide a panoramic view and one infrared camera steerable in horizontal plane.
