Tom Servo
Tom Servo is a fictional character from the American science fiction comedy television show ''Mystery Science Theater 3000'' (''MST3K''). Tom is one of two wise-cracking, robotic main characters of the show, built by Joel Robinson to act as a companion and help stave off madness as he was forced to watch low-quality films (Tom and the other bots, Crow, Gypsy, and Cambot, are made from parts that would have otherwise allowed Joel to actually control the film). At least during the Comedy Central era, he was somewhat more mature than his theatre companion, Crow T. Robot. Tom, more often than the others, signals the need to exit the theater to perform host segments. Overview Tom Servo is a red puppet that has a gumball machine (Carousel Executive Snack Dispenser) for a head, a body composed of a toy "Money Lover Barrel" coin bank and a toy car engine block, and a bowl-shaped hovercraft skirt (a Halloween "Boo Bowl") instead of legs. His arm assembly (according to the 1998 MST3K Off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servo (software)
Servo is an experimental browser engine designed to take advantage of the memory safety properties and concurrency features of the Rust programming language. It seeks to create a highly parallel environment, in which rendering, layout, HTML parsing, image decoding, and other engine components are handled by fine-grained, isolated tasks. It also makes use of GPU acceleration to render web pages quickly and smoothly. Servo has always been a research project. It began at the Mozilla Corporation in 2012, and its employees did the bulk of the work until 2020. This included the Quantum project, when portions of Servo were incorporated into the Gecko engine of Firefox. After Mozilla laid off all Servo developers in 2020, governance of the project was transferred to the Linux Foundation. Development work officially continues at the same GitHub repository with the project itself entirely volunteer driven. History Development of Servo began at the Mozilla Corporation in 2012. The p ...

Jennifer Servo
Jennifer Lynn Servo (born Jennifer Lynn Olson, September 23, 1979 – September 16, 2002) was an American news reporter whose murder remains unsolved. Servo worked as a news reporter at KPAX-TV in Missoula during her freshman year in college at the University of Montana, and later at KECI-TV, which serves most of western Montana. Background Servo graduated from Columbia Falls High School in 1998; a scholarship was established in Servo's name at the school after her death. Servo stated that she had the ambition to be "the next Katie Couric" and to work for a large news network. Servo graduated from the University of Montana in May 2002. Death Servo was offered her first full-time news reporter job from KRBC-TV in Abilene, Texas. Just months after she began working at KRBC, she was found murdered by strangulation and head trauma in her Abilene apartment. Servo's boyfriend at the time, Ralph Sepulveda, became a prime suspect. Brian Travers, Servo's co-worker at KRBC, also became a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servo Control
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) determines the position to be achieved by the servo. The PWM signal might come from a radio control receiver to the servo or from common microcontrollers such as the Arduino. Small hobby servos (often called radio control, or RC servos) are connected through a standard three-wire connection: two wires for a DC power supply and one for control, carrying the control pulses. The parameters for the pulses are the minimal pulse width, the maximal pulse width, and the repetition rate. Given the rotation constraints of the servo, neutral is defined to be the center of rotation. Different servos will have different constraints on their rotation, but the neutral position is always around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In control engineering a servomechanism, usually shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. On displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a car's cruise control uses closed-loop feedback, which classifies it as a servomechanism. Applications Position control A common type of servo provides ''position control''. Commonly, servos are electric, hydraulic, or pneumatic. They operate on the principle of negative feedback, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrohydraulic Servo Valve
An electrohydraulic servo valve (EHSV) is an electrically-operated valve that controls how hydraulic fluid is sent to an actuator.https://www.moog.com/literature/ICD/Valves-Introduction.pdf Servo valves are often used to control powerful hydraulic cylinders with a very small electrical signal. Servo valves can provide precise control of position, velocity, pressure, and force with good post-movement damping characteristics. History of electrohydraulic servo valves The electrohydraulic servo valve first appeared in World War II. The EHSVs in use during the 1940s was characterized by poor accuracy and slow response times due to the inability to rapidly convert electrical signals into hydraulic flows. The first two-stage servo valve used a solenoid to actuate a first stage spool which in turn drove a rotating main stage. The servo valves of the World War II-era were similar to this — using a solenoid to drive a spool valve. Advancement of EHSVs took off in the 1950s, largely due to ...

Marty Servo
Mario "Marty" Severino (November 3, 1919 – February 9, 1969) was a professional boxer who held the undisputed world welterweight championship being the NBA, NYSAC, and ''The Ring'' welterweight titles. Servo began boxing in the mid-1930s. He became a professional boxer in 1938 and was inducted into the World Boxing Hall of Fame in 1989. Amateur career Servo had an impressive amateur career. He captured the Golden Gloves and Diamond Belt Featherweight titles, and ended his career with an impressive record of 91-4. Professional career He turned professional as a lightweight and, in his first three years as a professional boxer, managed a 42–0–2 record. As a welterweight he lost two close decisions to the legendary Sugar Ray Robinson. Servo’s boxing career was interrupted by service in the United States Coast Guard during World War II. He resumed his career after the War and won the World Welterweight Title by knocking out Freddie "Red" Cochrane in the fourth round on ...

Servo (radio Control)
Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics. Most servos are rotary actuators although other types are available. Linear actuators are sometimes used, although it is more common to use a rotary actuator with a bellcrank and pushrod. Some types, originally used as sail winches for model yachting, can rotate continuously. Construction A typical servo consists of a small electric motor driving a train of reduction gears. A potentiometer is connected to the output shaft. Some simple electronics provide a closed-loop servomechanism. Operation The position of the output, measured by the potentiometer, is continually compared to the commanded position from the control (i.e., the radio control). Any difference gives rise to an error signal in the appropriate direction, which drives the electric motor either forwards or backwards, and moving the output shaft to the commanded position. When the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomotor
A servomotor (or servo motor) is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. Servomotors are not a specific class of motor, although the term ''servomotor'' is often used to refer to a motor suitable for use in a closed-loop control system. Servomotors are used in applications such as robotics, CNC machine, CNC machinery, and automated manufacturing. Mechanism A servomotor is a closed-loop controller, closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position commanded for the output shaft. The motor is paired with some type of encoder (position), position encoder t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servo Drive
A servo drive is an electronic amplifier used to power electric servomechanisms. A servo drive monitors the feedback signal from the servomechanism and continually adjusts for deviation from expected behavior. Function 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. A sensor attached to the servo motor reports the motor's actual status back to the servo drive. The servo drive then compares the actual motor status with the commanded motor status. It then alters the voltage, frequency or pulse width to the motor so as to correct for any deviation from the commanded status. In a properly configured control system, the servo motor rotates at a velocity that very closely approximates the velocity signal being received by the se ...
