  2. Polar diagram (sailing) - Wikipedia

    en.wikipedia.org/wiki/Polar_diagram_(sailing)

    A polar diagram, or polar plot, is a graph that shows a sailboat's potential speed over a range of wind speeds and relative wind angles. [1] It normally consists of the right side of a line chart with the radius representing the yacht speed and the angle representing the wind direction blowing from top to bottom.

  3. Spherical robot - Wikipedia

    en.wikipedia.org/wiki/Spherical_robot

    A spherical robot, also known as spherical mobile robot, or ball-shaped robot is a mobile robot with spherical external shape. [1] A spherical robot is typically made of a spherical shell serving as the body of the robot and an internal driving unit (IDU) that enables the robot to move. [2] Spherical mobile robots typically move by rolling over ...

  4. Drag curve - Wikipedia

    en.wikipedia.org/wiki/Drag_curve

    The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.

  5. Robot kinematics - Wikipedia

    en.wikipedia.org/wiki/Robot_kinematics

    In robotics, robot kinematics applies geometry to the study of the movement of multi-degree of freedom kinematic chains that form the structure of robotic systems. [ 1 ] [ 2 ] The emphasis on geometry means that the links of the robot are modeled as rigid bodies and its joints are assumed to provide pure rotation or translation .

  6. Radiation pattern - Wikipedia

    en.wikipedia.org/wiki/Radiation_pattern

    A rectangular radiation plot, an alternative presentation method to a polar plot In a directional antenna in which the objective is to emit the radio waves in one particular direction, the antenna is designed to radiate most of its power in the lobe directed in the desired direction.

  7. Five-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Five-bar_linkage

    In this configuration, the controlled endpoint or end-effector is the point D, where the objective is to control its x and y coordinates in the plane in which the linkage resides. The angles theta 1 and theta 2 can be calculated as a function of the x,y coordinates of point D using trigonometric functions .

  8. 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.

  9. Cartesian coordinate robot - Wikipedia

    en.wikipedia.org/wiki/Cartesian_coordinate_robot

    Kinematic diagram of Cartesian (coordinate) robot A plotter is a type of Cartesian coordinate robot.. A Cartesian coordinate robot (also called linear robot) is an industrial robot whose three principal axes of control are linear (i.e. they move in a straight line rather than rotate) and are at right angles to each other.
