  2. Six degrees of freedom - Wikipedia

    en.wikipedia.org/wiki/Six_degrees_of_freedom

    Robot arms are described by their degrees of freedom. This is a practical metric, in contrast to the abstract definition of degrees of freedom which measures the aggregate positioning capability of a system. [3] In 2007, Dean Kamen, inventor of the Segway, unveiled a prototype robotic arm [4] with 14 degrees of freedom for DARPA.

  3. Degrees of freedom (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom_(mechanics)

    An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR spatial four-bar linkage.

  4. Motion simulator - Wikipedia

    en.wikipedia.org/wiki/Motion_simulator

    A motion platform base for a simulator giving all six degrees of freedom to a simulator mounted on the base plate, using six jacks, generally known as a hexapod A motion simulator or motion platform is a mechanism that creates the feelings of being in a real motion environment. [ 1 ]

  5. Researcher degrees of freedom - Wikipedia

    en.wikipedia.org/wiki/Researcher_degrees_of_freedom

    [2] [3] [4] However, researcher degrees of freedom can lead to data dredging and other questionable research practices where the different interpretations and analyses are taken for granted [5] [6] Their widespread use represents an inherent methodological limitation in scientific research, and contributes to an inflated rate of false-positive ...

  6. Degrees of freedom (physics and chemistry) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom_(physics...

    In physics and chemistry, a degree of freedom is an independent physical parameter in the chosen parameterization of a physical system.More formally, given a parameterization of a physical system, the number of degrees of freedom is the smallest number of parameters whose values need to be known in order to always be possible to determine the values of all parameters in the chosen ...

  7. Degrees of freedom (statistics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom...

    R. A. Fisher used n to symbolize degrees of freedom but modern usage typically reserves n for sample size. When reporting the results of statistical tests, the degrees of freedom are typically noted beside the test statistic as either subscript or in parentheses. [6]

  8. Freedom and constraint topologies - Wikipedia

    en.wikipedia.org/wiki/Freedom_and_constraint...

    Freedom and constraint topologies (a.k.a., freedom, actuation, and constraint topologies; or simply FACT) [1] [2] [3] is a mechanical design framework developed by Dr. Jonathan B. Hopkins. The framework offers a library of vector spaces with visual representations to guide the analysis and synthesis of flexible systems.

  9. Dynamic simulation - Wikipedia

    en.wikipedia.org/wiki/Dynamic_simulation

    The first applications of computer simulations for dynamic systems was in the aerospace industry. [5] Commercial uses of dynamic simulation are many and range from nuclear power, steam turbines, 6 degrees of freedom vehicle modeling, electric motors, econometric models, biological systems, robot arms, mass-spring-damper systems, hydraulic systems, and drug dose migration through the human body ...
