Even in sailboats running under engine, the self steering gear can be used to keep the boat heading into the wind to easily set or change sails (exception: sheet-to-tiller principle). As wind direction sensors are used. a) a wind vane mounted on an axis being tilted more or less towards the horizon (wind vane self-steering) b) the pressure of ...
The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
Radio-controlled boat. A mass-produced radio-controlled yacht. In 1898, Tesla demonstrated a radio-controlled boat ( U.S. patent 613,809 — Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles ). A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment.
An electronic speed control ( ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking . Miniature electronic speed controls are used in electrically powered radio controlled models. Full-size electric vehicles also have systems to control the speed ...
Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
A large multi-tasked shallow draught vessel, approximately 65 metres (213 ft) long, with a top speed of 14 knots (26 km/h; 16 mph) that can stay at sea up to 28 days. Has a crane, a large cargo hold and deck area, can launch and recover rigid-hull inflatable boats and utility craft.
Brushless DC electric motor. The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The grey ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor.
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 (often a ...
