As pointed out in Section 1.2, the tasks for which robots are applied in industry and other fields are of very diverse complexity. The more complex the task a robot has to perform and the more strict the requirements for its performing, the more complex should be the control system of the robot.

Kinematics of eye movement control
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1995In this paper a kinematic description of the restrictions imposed on the eye movements is presented. The restrictions arise from a pattern of nonlinear interactions between desired changes in viewing direction and current eye position. It is shown that various reported relations between eye torsion and viewing direction can be derived by changing only ...

Kinematic Control of Robots With Joint Constraints
Journal of Dynamic Systems, Measurement, and Control, 1999Kinematic control of robot manipulators requires that joint mechanical limits are taken into account in order to avoid the interruption of the task at hand if joint limits are reached. A novel approach to this problem is presented and compared with state of the art techniques.

The planar law of inter-segmental co-ordination we described may emerge from the coupling of neural oscillators between each other and with limb mechanical oscillators. Muscle contraction intervenes at variable times to re-excite the intrinsic oscillations of the system when energy is lost. The hypothesis that a law of coordinative control results from

Kinematic Modeling and Control
2008This chapter describes the kinematic modeling of a car-like mobile robot. Kinematic modeling is often used because of its simplicity and accuracy in predicting the car’s behavior under normal driving conditions. This type of modeling uses the nonholonomic constraints of the system as described in Section 2.3.

KINEMATIC INSTABILITY OF KINEMATICALLY CONSTRAINED MANIPULATORS UNDER PURE FORCE CONTROL
IFAC Proceedings Volumes, 2006Abstract In this paper, we consider the problem of force control for kinematically constrained manipulators (KCMs). In particular, we show that the force component selection is not appropriate in general to solve the force control problem for KCMs.

A robotic system is kinematically redundant when it possesses more degrees of freedom than those required to execute a given task. A generic manipulation task is usually given in terms of trajectories for the end effector, specially position and orientation.

KINEMATIC GPS CONTROL FOR PHOTOGRAMMETRY
The Photogrammetric Record, 1992Abstract Relative positioning of camera air stations by postprocessing of differential GPS phase observations is capable of very high accuracy and its application to aerial triangulation is expected to be simple and highly economic. The method is reviewed and some technical and operational problems are discussed.

Optimal control of reaching includes kinematic constraints
Journal of Neurophysiology, 2013We investigate adaptation under a reaching task with an acceleration-based force field perturbation designed to alter the nominal straight hand trajectory in a potentially benign manner: pushing the hand off course in one direction before subsequently restoring towards the target.
