Gemini-scout mine rescue robot toy
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 Occupational 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 also climb stairs and travel through gravel and sand pits. The unit can pivot in gemini-scout mine rescue robot toy and traverse degree climbs gemini-scout mine rescue robot toy 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 gemini-scout mine rescue robot toy out of buildings or underground facilities. Planetary gearheads are used to gemini-scout mine rescue robot toy the amount of torque available in a small diameter package, and their concentric input and output facilitates simple mounting arrangements.
They also operate between temperature ranges from degrees C to 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 gemini-scout mine rescue robot toy 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 as 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 intelligence, 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. 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 gemini-scout mine rescue robot toy that aid humans.
Sensors and gripper arms can simply be attached and removed as needed. The latest addition is a small crawler robot that magnetically "sticks" to metal walls and is able to move in all directions. It carries cameras, sensors and tools for inspection or maintenance work in tight pipes and on the outer hulls of tanks or ships.
