Atlas (robot)
Atlas is a bipedal humanoid robot primarily developed by the American robotics company Boston Dynamics with funding and oversight from the U.S. Defense Advanced Research Projects Agency (DARPA). The robot was initially designed for a variety of search and rescue tasks, and was unveiled to the public on July 11, 2013. Design and development The design and production of Atlas were overseen by DARPA, an agency of the United States Department of Defense, in cooperation with Boston Dynamics. One of the robot's hands was developed by Sandia National Laboratories, while the other was developed by iRobot. In 2013, DARPA program manager Gill Pratt compared the prototype version of Atlas to a small child, saying that "a 1-year-old child can barely walk, a 1-year-old child falls down a lot ... this is where we are right now". Atlas is based on Boston Dynamics' earlier PETMAN humanoid robot, and is illuminated with blue LEDs. Atlas is equipped with two vision systems – a laser rangef ...

DARPA Robotics Challenge
The DARPA Robotics Challenge (DRC) was a prize competition funded by the US Defense Advanced Research Projects Agency. Held from 2012 to 2015, it aimed to develop semi-autonomous ground robots that could do "complex tasks in dangerous, degraded, human-engineered environments." The DRC followed the DARPA Grand Challenge and DARPA Urban Challenge. It began in October 2012 and was to run for about 33 months with three competitions: a Virtual Robotics Challenge (VRC) that took place in June 2013; and two live hardware challenges, the DRC Trials in December 2013 and the DRC Finals in June 2015. Besides spurring development of semi-autonomous robots, the DRC also sought to make robotic software and systems development more accessible beyond the end of the program. To that end, the DRC funded the adaptation of the GAZEBO robot simulator by the Open Source Robotics Foundation (OSRF) for DRC purposes and the construction of six Boston Dynamics ATLAS robots that were given to the teams tha ...

Balance Beam
The balance beam is a rectangular artistic gymnastics apparatus and an event performed using the apparatus. Both the apparatus and the event are sometimes simply referred to as "beam". The English abbreviation for the event in gymnastics scoring is BB. The beam is a small, thin beam which is typically raised from the floor on a leg or stand at both ends. The balance beam is only performed competitively by female gymnasts. Beams are usually covered with leather-like material and are only four inches wide. Balance beams used in international gymnastics competitions must conform to the guidelines and specifications set forth by the International Gymnastics Federation ''Apparatus Norms'' brochure. Several companies manufacture and sell beams, including AAI (USA), Janssen Fritsen (Europe) and Acromat (Australia). Most gymnastics schools purchase and use balance beams that meet the FIG's standards, but some may also use beams with carpeted surfaces for practice situations. While learning ...

Parkour
Parkour () is an athletic training discipline or sport in which practitioners (called ''traceurs'') attempt to get from point A to point B in the fastest and most efficient way possible, without assisting equipment and often while performing artistic-gymnastic maneuvers. With roots in military obstacle course training and martial arts, parkour includes running, climbing, swinging, vaulting, jumping, plyometrics, rolling, gymnastics, and quadrupedal movement—whatever is suitable for a given situation. Parkour is an activity that can be practiced alone or with others, and is usually carried out in urban spaces, though it can be done anywhere. It involves seeing one's environment in a new way, and envisioning the potential for navigating it by movement around, across, through, over and under its features. Although practitioners of Parkour often perform flips and other acrobatic movements, these are not considered a part of Parkour proper. The practice of similar movements had ...

Do You Love Me
"Do You Love Me" is a rhythm and blues song recorded by the Contours in 1962. Written and produced by Motown Records owner Berry Gordy Jr., it appeared twice on the ''Billboard'' Hot 100 chart, reaching numbers three in 1962 and eleven in 1988. As with many American R&B songs of the 1960s, "Do You Love Me?" was recorded by several British Invasion groups. A 1963 version by Brian Poole and the Tremeloes reached number one on the UK Singles Chart. It also became a hit for the Dave Clark Five, reaching number 11 on the ''Billboard'' Hot 100 in 1964. Background and recording Berry Gordy wrote "Do You Love Me" and earmarked it for the Temptations, who had no top-40 hits to their name yet. However, when Gordy was looking for the group to record it, he could not find them; they had gone to church to see gospel groups the Dixie Hummingbirds, the Harmonizing Four and the Swan Silvertones. Instead, the Contours, who had turned up to the studio to record their song "It Must Be Love", we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music Video
A music video is a video of variable duration, that integrates a music song or a music album with imagery that is produced for promotion (marketing), promotional or musical artistic purposes. Modern music videos are primarily made and used as a music marketing device intended to promote the sale of Music Recording, music recordings. Although the origins of music videos date back to musical short, musical short films that first appeared, they again came into prominence when Paramount Global's MTV based its format around the medium. These kinds of videos were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip", "film clip" or simply "video". Music videos use a wide range of styles and contemporary video-making techniques, including animation, live action, live-action, documentary film, documentary, and non-narrative approaches such as Non-narrative film, abstract fi ...

Somersault
A somersault (also ''flip'', ''heli'', and in gymnastics ''salto'') is an acrobatic exercise in which a person's body rotates 360° around a horizontal axis with the feet passing over the head. A somersault can be performed forwards, backwards or sideways and can be executed in the air or on the ground. When performed on the ground, it is typically called a roll. Types Body positions Somersault may be performed with different positions, including tucked, piked (bent at the hips), straddled, and layout (straight body). Direction The sport of tumbling does not require participants to combine both front and back elements, and most tumblers prefer back tumbling as it is easier to build momentum. Arabian saltos begin backwards, continue with a half twist to forwards, and end with one or more saltos forwards. They can be trained by beginning with an Arabian dive roll and adding a front salto to it. They are counted as front tumbling in women's artistic gymnastics and back tum ...

Handstand
__NOTOC__ A handstand is the act of supporting the body in a stable, inverted vertical position by balancing on the hands. In a basic handstand, the body is held straight with arms and legs fully extended, with hands spaced approximately shoulder-width apart and the legs together. There are many variations of handstands, all of which require the performer to possess adequate balance and upper body strength. Kinematics Handstands use the wrist flexor muscles as well as the anterior deltoid, pectoralis major, latissimus dorsi, biceps brachii, and trapezius descendens. It is considered demanding in terms of both the muscle and joint requirement. According to a 2017 study most handbalancers use wrist movement to maintain balance in a handstand. Another study found that handbalancers who were also expert gymnasts had better coordination than those at an intermediate level of gymnastics. More advanced practitioners also altered their center of pressure less to change the center of mas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floor (gymnastics)
In gymnastics, the floor is a specially prepared exercise surface, which is considered an apparatus. It is used by both male and female gymnasts. The gymnastics event performed on the floor is called floor exercise. The English abbreviation for the event in gymnastics scoring is FX. A spring floor is used in all of gymnastics to provide more bounce, and also help prevent potential injuries to lower extremity joints of gymnasts due to the nature of the apparatus, which includes the repeated pounding required to train it. Cheerleading also uses spring floors for practice. The sprung floor used for indoor athletics, however, is designed to reduce bounce. The apparatus The apparatus originated as a 'free exercise' for men, very similar to the floor exercise of today. Most competitive gymnastics floors are spring floors. They contain springs and/or a rubber foam and plywood combination which make the floor bouncy, soften the impact of landings, and enable the gymnast to gain heigh ...

Flip (acrobatic)
An acrobatic flip is a sequence of body movements in which a person leaps into the air and then rotates one or more times while airborne. Acrobatic flips are performed in acro dance, free running, gymnastics, cheerleading, high jumping, tricking (martial arts), goal celebrations and various other activities. This is in contrast to freestyle BMX flips, in which a person revolves in the air about a bicycle. Acrobatic flips can be started from a stationary, standing position and they are also commonly executed immediately following another rotational move, such as a roundoff or handspring, so as to take advantage of the angular momentum developed in the preceding move. In general, the hands do not touch the floor during execution of a flip and performers typically strive to land on the feet in an upright position, but it is not required to be considered a flip. Classification Many variations of flips exist, with usage depending on the particular type of activity. In gymnastics, fo ...

LIDAR
Lidar (, also LIDAR, or LiDAR; sometimes LADAR) is a method for determining ranges (variable distance) by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It can also be used to make digital 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has terrestrial, airborne, and mobile applications. ''Lidar'' is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. It is also used in control and navigation for som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
