Abstract: The paper deals with constructing the inertial navigation system (hereafter INS) which will be utilized for the calibration of a robotic workplace. The calibration is necessary for adapting the simulation of a production device model to real geometric conditions. The goal is to verify experimentally the proposed inertial navigation system in real conditions of the industrial robot operation.

Abstract: This paper discusses the problem of effective motion planning for industrial robots. The first part dealt with current method for off-line motion planning. In the second part the presented work is done by one of the simulation systems with automatic trajectory generation and off-line programming capability. A spot welding process is involved. The practical application of this step strongly depends on the method for robot path optimization with high accuracy, thus transform the path into a time and energy optimal robot program for the real world, which is discussed in the third step.

Abstract: Series ferrofluid based sensors are novel sensors which use ferrofluid as inductive core to measure signals. The physical properties of ferrofluid affect mostly on performance parameter of these series sensors. There is several generality regularity for ferrofluid appliedd in series sensors. This paper analyses the generality of parameter controlling for properties of ferrofluid used in series ferrofluid sensors. The working area of magnetization curve of ferrofluid used in series sensors should be in its linear area where the permeability of ferrofluid is considered as a constant. The magnetic nano-particles generally obtained by reaction of ferrous chloride and ferric chloride. With the increment of viscosity and density of ferrofluid, the saturation magnetic intensity of ferrofluid increases. The concentration of reacted solution is better to be 0.6mol/L. Saturation magnet intensity of magnetic nano-partcles is highest as the molar ratio of trivalent iron ion to bivalent iron ion is equal to 1.75. The reacted temperature is better between 65~80°C while PH value of solution is in a weak alkaline state.
