This paper attempts to present a comprehensive summary of research results in the use of visual information to control robot manipulators and related mechanisms. An extensive bibliography is provided which also includes important papers from the elemental disciplines upon which visual servoing is based.

The sensory processing hierarchu constantly fills the world model with processed sensor information.
The identified model gives a good description of the global behavior of this robot. The inverse cost reduction sometimes also results in a higher level of disturbances and control servo has an appropriate tuning and uses feedforw.
Compliant motion of a manipulator occurs when the manipulator position is constrained by the task geometry. Compliant motion may be produced either by a passive mechanical compliance built in to the manipulator, or by an active compliance implemented in the control servo loop. The second method, called force control, is the subject of this paper.
Citalan-lara et al citalan2014multidisciplinary proposed analytical modeling of the mechanism, the controller and the servo drive subsystem of a kind of manipulator and optimized the manipulator with six objectives simultaneously. The research of parallel robot modeling and optimization has also made progress.
Models are also defined for position control and force control, providing a precise semantics for compliant motion primitives in manipulation programming languages. The formalism serves as a simple interface between the manipulator and the programmer, isolating the programmer from the fundamental complexity of low-level manipulator control.

Neural-network-based contouring control for robotic manipulators in operational space abstract: this brief presents a contouring control scheme for robotic manipulators. The geometric properties of the desired contour are incorporated in the controller design phase, and the resulting controller has been structured as a two-layered hierarchical.
For example, program execution stops, however power to the servo motors remain on, if restarting is desired. Home position a known and fixed location on the basic coordinate axis of the manipulator where it comes to rest, or to an indicated zero position for each axis.

The controller can accept commands in the form of high level cartesian goal points down to low level servo commands of joint position, torque or current. An off-line/on-line programming and simulation environment is available, which allows the controller to use a sophisticated world model database in a real-time fashion.
At each level, the input s is a combination of a command vector from a higher level plus a feedback vector from sensors or from a world model or peer agents. The output p is a command to a lower level module, a next state, and possibly a message to a peer.

Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use rc servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometer positioning accuracy.
Through an analysis of the kinematics and dynamics relations between the target positioning of manipulator joint angles of an apple-picking robot, the sliding-mode control (smc) method is introduced into robot servo control according to the characteristics of servo control. However, the biggest problem of the sliding-mode variable structure control is chattering, and the speed, inertia.

Shotcrete manipulator has been widely used in the construction of high-speed railways, coal mines and other tunnels. At present, workers are still using the remote controller to control the manipulator for spraying operations. There are problems such as high operation risk, large personal injuries, and low construction quality. In order to improve the automation of tunnel construction, this.
