Forward model of an arm movement. The motor command, u(t), of the arm movement is input to the plant and the predicted position of the body, x̃(t), is output. In the subject area of control theory, an internal model is a process that simulates the response of the system in order to estimate the outcome of a system disturbance.
Forward models are a predictive internal model of motor control that takes the available perceptual information, combined with a particular motor program, and tries to predict the outcome of the planned motor movement. Forward models structure action by determining how the forces, velocities, and positions of motor components affect changes in ...
A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.
Performing a three-point turn (shown for right-hand traffic). The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears.
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
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 .
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
A friction motor is a simple mechanism to propel toy cars, trucks, trains, action figures and similar toys. The motor consists of a large flywheel which is connected to the drive wheels of the toy via a gear train with very low gear ratio , so that the flywheel revolves much faster than the wheels.
