Swarm Robotics
Swarm robotics is the study of how to design independent systems of robots without centralized control. The emerging swarming behavior of robotic swarms is created through the interactions between individual robots and the environment.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. This idea emerged on the field of artificial swarm intelligence, as well as the studies of insects, ants and other fields in nature, where swarm behavior occurs. Relatively simple individual rules can produce a large set of complex swarm behaviors. A key component is the communication between the members of the group that build a system of constant feedback. The swarm behavior involves constant change of individuals in cooperation with others, as well as the behavior of the whole group. Key Attributes of Robotic Swarms The design of swarm rob ...

Formation Flying
Formation flying is the flight of multiple objects in coordination. Formation flying occurs in nature among flying and gliding animals, and is also conducted in human aviation, often in military aviation and air shows. A multitude of studies have been performed on the performance benefits of aircraft flying in formation. History Birds have been known to receive performance benefits from formation flight for over a century, through aerodynamic theory of Wieselsberger in 1914. Formation flight in human aviation originated in World War I, when fighter aircraft were assigned to escort reconnaissance aircraft. It was found that pairs of aircraft were more combat effective than single aircraft, and therefore, military aircraft would always fly in formations of at least two. By World War II, pilots had discovered other strategic advantages to formation flight such as enhanced stability and optimal visibility. Close Formation There are 5 main reasons for a close formation flight: # ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Printing
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology; in this context, the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise infeasi ...

Swarm 3D Printing
Swarm 3D printing or cooperative 3D printing or swarm manufacturing is a digital manufacturing platform that employs a swarm of mobile robots with different functionalities to work together to print and assemble products based on digital designs. A digital design is first divided into smaller chunks and components based on its geometry and functions, which are then assigned to different specialized robots for printing and assembly in parallel and in sequence based on the dependency of the tasks. The robots typically move freely on an open factory floor, or through the air, and could carry different tool heads. Some common tool heads include material deposition tool heads (e.g., filament extruder, inkjet printhead), pick and place tool head for embedding of pre-manufactured components, laser cutter Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by scho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Lincoln
The University of Lincoln is a public university, public research university in Lincoln, England, Lincoln, England, with origins dating back to 1861. It gained university status in 1992 and its present name in 2001. The main campus is in the heart of the city of Lincoln, England, Lincoln alongside the Brayford Pool. There are satellite campuses across Lincolnshire in Riseholme, Lincolnshire, Riseholme and Holbeach and graduation ceremonies take place in Lincoln Cathedral. History 19th and 20th centuries The University of Lincoln developed out of several educational institutions, including ''Hull School of Art'' (1861), ''Hull Technical Institute'' (1893), the Roman Catholic teacher-training ''Endsleigh College'' (1905), ''Hull Central College of Commerce'' (1930), and ''Kingston upon Hull College of Education'' (1913). These merged in 1976 into ''Hull College of Higher Education'', with a change of name to ''Humberside College of Higher Education'' in 1983, absorbing several cour ...

Kilobot
The Kilobot is a 3.3 cm tall low-cost swarm robot developed by Radhika Nagpal and Michael Rubenstein at Harvard University. They can act in groups (over a thousand), to execute commands programmed by users that could not be executed by individual robots. A problem with research on robot collectives is that the cost of individual units is high. The Kilobot's total cost of parts is under $15. In addition to low cost, it has applications such as collective transport, human-swarm interaction, and shape self-assembly. Development During November 2010, Michael Rubenstein and Radhika Nagpal began the development of the Kilobot with the support of the Wyss Institute for Biologically Inspired Engineering and the National Science Foundation. The two primary objectives of the Kilobot's design were to keep the cost low while having enough functionality to perform an array of collective tasks. One of the developer's goals was to allow the Kilobot to run the program S-DASH: S-DASH S-DASH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simultaneous Localization And Mapping
Simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an Intelligent agent, agent's location within it. While this initially appears to be a chicken or the egg problem, there are several algorithms known to solve it in, at least approximately, tractable time for certain environments. Popular approximate solution methods include the particle filter, extended Kalman filter, covariance intersection, and GraphSLAM. SLAM algorithms are based on concepts in computational geometry and computer vision, and are used in robot navigation, robotic mapping and odometry for virtual reality or augmented reality. SLAM algorithms are tailored to the available resources and are not aimed at perfection but at operational compliance. Published approaches are employed in self-driving cars, unmanned aerial vehicles, autonomous underwater vehicles, Rover (space exploration), planetary r ...

Robot Localization
Robot localization denotes the robot's ability to establish its own position and orientation within the frame of reference. Path planning is effectively an extension of localization, in that it requires the determination of the robot's current position and a position of a goal location, both within the same frame of reference or coordinates. Map building can be in the shape of a metric map or any notation describing locations in the robot frame of reference. For any mobile device, the ability to navigate in its environment is important. Avoiding dangerous situations such as collisions and unsafe conditions (temperature, radiation, exposure to weather, etc.) comes first, but if the robot has a purpose that relates to specific places in the robot environment, it must find those places. This article will present an overview of the skill of navigation and try to identify the basic blocks of a robot navigation system, types of navigation systems, and closer look at its related building ...

Motion Capture
Motion capture (sometimes referred as mocap or mo-cap, for short) is the process of recording high-resolution motion (physics), movement of objects or people into a computer system. It is used in Military science, military, entertainment, sports, medical applications, and for validation of computer vision and robots. In films, television shows and video games, motion capture refers to recording actions of Motion-capture acting, human actors and using that information to animate Character animation, digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving. In motion capture sessions, movements of one or more actors are sampled many times per second. Whereas early techniques used 3D reconstruction from multiple images, ima ...
