Gemini-Scout Mine Rescue Vehicle

5 stars based on 71 reviews

Reliability, ability to travel across varied terrains, and accurate operation are essential elements for the drive system and camera controls on mining rescue robots. Contributed by Maxon Precision Motors. Mine rescue robots are designed to replace humans in the most dangerous, early stages of rescue planning and response during a mining accident.

When mines collapse, speed in reaching those affected is important. First arrival crews cannot enter an already dangerous situation where structural weakness, poisonous vapors, explosive gases, flooding, and much more are probable.

Such potentially deadly conditions create multiple challenges for first responders, and often limit their ability to assess the situation quickly and efficiently.

Plus, once the dangers are determined, it is critical that proper supplies are delivered to trapped miners or other personnel. The Gemini-Scout Mine Rescue Robot, developed by Sandia National Laboratories through a National Institute for Gemini-scout mine rescue robot toys Safety and Health NIOSH sponsored program, is a robotic first responder that functions primarily as a scout, carrying a payload of analytical equipment, its own lighting system, and several cameras.

The unit enters, exits and maneuvers the terrain through the use of track propulsion with an articulated body configuration that allows it to climb over and through rubble piles, over uneven terrain, through water, and small openings. The system can gemini-scout mine rescue robot toys climb stairs and travel through gravel and sand pits. The unit can pivot in place and traverse degree climbs with few problems. The Gemini-Scout has a split frame and features four tracks.

Each track uses one drive motor. The motors are 2-pole, electronically commutated devices, which provides them with extremely long motor life because there are no mechanical brushes to wear out.

Electronic commutation further minimizes electrical noise caused by mechanical brushes. High-energy neodymium magnets are used to make the motors highly responsive and to keep the motors compact. The Gemini-Scout easily climbs stairs to get into and gemini-scout mine rescue robot toys of buildings or underground facilities. Planetary gearheads are used to increase the amount of torque available in a small diameter package, and their concentric input and output facilitates simple mounting arrangements.

Gemini-scout mine rescue robot toys also operate between temperature ranges from degrees C gemini-scout mine rescue robot toys 80 degrees C 5 to degrees F. For lower torque applications, maxon supplies a lower-cost plastic version of their gearheads. The Gemini-Scout is able to carry a payload of about 50 pounds of batteries, and can handle an additional 50 pounds of payload, whether for diagnostics of the environment or supplies and clothing for those trapped in the affected area.

The unit weighs pounds and moves at a speed of 3. It is only two feet tall at the tower, which houses the lighting system and surveillance camera. Although there are forward facing and rear facing cameras to help with navigation, the unit also houses an inspection camera with pan and tilt capabilities.

As with the other maxon components, the motors and gearheads are designed for compactness and efficiency even under the harsh and hazardous conditions that the Gemini-Scout often entails. The Intelligent Systems, Robotics, and Cybernetics ISRC group at Sandia developed the Gemini-Scout as a platform designed to be scalable—from smaller, more compact robots to larger robots able to handle very heavy payloads.

Each robot is completely configurable to accommodate heavier payloads such gemini-scout mine rescue robot toys additional sensors and analytical equipment, to support a wide variety of missions including boarder tunnels, payload deployment and delivery, search and rescue missions, as well as gemini-scout mine rescue robot toys, surveillance, and reconnaissance.

The maxon components were selected for their accuracy, high efficiency, compactness, power, and long life. These motors range in size from 4 - 90 mm and are available up to watts. We combine electric motors, gears and DC motor controls into high-precision, intelligent drive systems that can be custom-made to fit the specific needs of customer applications.

Stairs are still unsurmountable obstacles for many robots. Yet a young team at ETH Zurich is building a vehicle designed to negotiate steps with ease — by hopping.

A question of torque - Inspection robots for pipes and ducts, rescue robots in disaster areas, or humanoid robots — they all have one thing in common: They are mobile robots that aid humans.

Sensors and gripper arms can simply be attached and removed as needed. Comments 0 This post does not have any comments. Be the first to leave a comment below. Post A Comment You must be logged in before you can post a comment.

According to a team of U. It is worth mentioning that in mines people can face serious dangers such as hazardous gases, flooded channels, weakened walls and more. Researchers from the Sandia National Laboratories in Albuquerque stated that their latest 4-foot long invention, called Gemini-Scout Mine Rescue Robot, will be able to pass through 18 inches of water, travel over boulders and other obstacles and search for survivors ahead of rescuers, accurately examining environments.

In addition, the robot can deliver food, medicine and other important cargo to people trapped underground. More about the machine find here. Two electrical engineers, Ayanna Howard and Paul Robinette, managed to come up with small and mobile machines able to instantly provide information to emergency personnel on the exact location of people that are injured or trapped in a burning construction. The duo at the Georgia Institute of Technology in Atlanta says these small robots can also help trapped people by guiding them to the closest exit, finding the safest route through smoke filled surroundings.

Before the operation the robots are programmed in "hunt" mode to search for victims, but as soon as they identify humans that needs assistance they instantly switch to "leader" mode to guide people to a safe location. In case the machine spots an injured person it will transmit the information on the location of that person to the rescuers. Developed by a Japanese firm called BL Autotec, the remote-controlled robotic hand can easily open a wide range of doors during rescue operations.

The machine can be used to save people trapped in buildings during fire, earthquake, as well as during nuclear, biological and chemical disasters. A very interesting feature of this invention is that it can be worn by a human as a backpack. The Japanese company mounted a CCD camera on its kilogram machine. In addition, the robot has LED lighting to work remotely in low light zones.

With the help of a micro motor the 4 wings of the robot make 30 moves each second. The invention of the year-old researcher can move up, down, left or right using a built-in infrared sensor. It can be used during rescue missions to look for people trapped among ruins. At the same time the machine may be useful to police that can use it to search for criminals.

Find more about it here. Japan has been greatly affected by earthquakes and tsunamis that made thousands of victims in a short period of time. With this in mind a group of researchers from Tohoku University was able to invent a robot that resembles a snake and which can move into the debris in search of people trapped under ruins. It can move deep into the devastated buildings and use the camera to help rescuers spot victims.

The machine is composed of a foot long fiberscope wrapped in a special servomotor system. The Active Scope Camera features hair-like structures that use vibrations in order to move the robot forward and allow it to reach a speed of 2. Another group of Japanese scientists from the Chiba Institute of Technology's Future Robotics Technology Center is looking forward to launch a robot that will be able to study hazardous sites suffered from disasters. Led by Eiji Koyanagi, the team came up with a robot that can roll on treads and sense chemical, biological, radiological or nuclear hazards in regions that firefighters are unable to reach.

The robot features a built-in camera and can move at a speed of approximately 5. Developed by scientist from the Kyoto University, this mini rescue robot was used to rescue people trapped inside a partially devastated structure in Hachinohe, a small city located in North Eastern Japan.

Part of the building collapsed as a result of an earthquake, and it was very difficult for rescuers to enter it themselves. KOHGA3, which was officially presented in , is a kilogram robot that was used during the mission. The robot is able to climb upstairs and deal with various obstacles.
