  2. Box step - Wikipedia

    en.wikipedia.org/wiki/Box_Step

    This is the most common dance step in the waltz. In international standard dance competition, there is a similar step called closed change. [3] In a typical example, the leader begins with the left foot and proceeds as follows. [2] First half-box: forward-side-together; Second half-box: backwards-side-together; Every step is with full weight ...

  3. Change step - Wikipedia

    en.wikipedia.org/wiki/Change_step

    The man steps forward on right foot while the lady steps backward on the opposing (i.e., left) foot. They will then step to the side (and possibly slightly forward, in relation to the man) on the other foot, and conclude the figure by closing the first foot beside the second. Each step takes up a full beat of the music.

  4. Step response - Wikipedia

    en.wikipedia.org/wiki/Step_response

    Figure 4: Black box representation of a dynamical system, its input and its step response. This section provides a formal mathematical definition of step response in terms of the abstract mathematical concept of a dynamical system S {\displaystyle {\mathfrak {S}}} : all notations and assumptions required for the following description are listed ...

  5. Inverse kinematics - Wikipedia

    en.wikipedia.org/wiki/Inverse_kinematics

    Forward vs. inverse kinematics. In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.

  6. Forward kinematics - Wikipedia

    en.wikipedia.org/wiki/Forward_kinematics

    In robot kinematics, forward kinematics refers to the use of the kinematic equations of a robot to compute the position of the end-effector from specified values for the joint parameters. [ 1 ] The kinematics equations of the robot are used in robotics , computer games , and animation .

  7. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    The dead time θ is the amount of time between when the step change occurred and when the output first changed. The time constant (τ p) is the amount of time it takes for the output to reach 63.2% of the new steady-state value after the step change. One downside to using this method is that it can take a while to reach a new steady-state value ...

  8. Incremental encoder - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoder

    The resolution of an incremental encoder is a measure of the precision of the position information it produces. Encoder resolution is typically specified in terms of the number of A (or B) pulses per unit displacement or, equivalently, the number of A (or B) square wave cycles per unit displacement.

  9. Quick return mechanism - Wikipedia

    en.wikipedia.org/wiki/Quick_return_mechanism

    In addition to the kinematic analysis of a quick return mechanism, there is a dynamic analysis present. At certain lengths and attachments, the arm of the mechanism can be evaluated and then adjusted to certain preferences. For example, the differences in the forces acting upon the system at an instant can be represented by D'Alembert's ...
