  2. Servo control - Wikipedia

    en.wikipedia.org/wiki/Servo_control

    Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...

  3. Servomotor - Wikipedia

    en.wikipedia.org/wiki/Servomotor

    A servomotor (or servo motor or simply servo) [1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. [ 1 ] [ 2 ] It constitutes part of a servomechanism , and consists of a suitable motor coupled to a sensor for position feedback and a controller ...

  4. Servomechanism - Wikipedia

    en.wikipedia.org/wiki/Servomechanism

    On the low end are inexpensive radio control servos (RC servos) used in radio-controlled models which use a free-running motor and a simple potentiometer position sensor with an embedded controller. The term servomotor generally refers to a high-end industrial component while the term servo is most often used to describe the inexpensive devices ...

  5. Servo drive - Wikipedia

    en.wikipedia.org/wiki/Servo_drive

    A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal. Typically, the command signal represents a desired velocity, but can also represent a desired torque or position.

  6. Visual servoing - Wikipedia

    en.wikipedia.org/wiki/Visual_servoing

    Visual servo systems, also called servoing, have been around since the early 1980s , [11] although the term visual servo itself was only coined in 1987. [4] [5] [6] Visual Servoing is, in essence, a method for robot control where the sensor used is a camera (visual sensor).

  7. Phase-locked loop - Wikipedia

    en.wikipedia.org/wiki/Phase-locked_loop

    A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.

  8. Synchro - Wikipedia

    en.wikipedia.org/wiki/Synchro

    A different type of receiver, called a control transformer (CT), is part of a position servo that includes a servo amplifier and servo motor. The motor is geared to the CT rotor, and when the transmitter's rotor moves, the servo motor turns the CT's rotor and the mechanical load to match the new position.

  9. Arduino - Wikipedia

    en.wikipedia.org/wiki/Arduino

    Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
