This book deals with the problems related to planning motion laws and t- jectories for the actuation system of automatic machines, in particular for those based on electric drives, and robots. The problem of planning suitable trajectories is relevant not only for the proper use of these machines, in order to avoid undesired e?ects such as vibrations or even damages on the mech- ical structure, but also in some phases of their design and in the choice and sizing of the actuators. This is particularly true now that the concept of “el- tronic cams” has replaced, in the design of automatic machines, the classical approach based on “mechanical cams”. The choice of a particular trajectory has direct and relevant implications on several aspects of the design and use of an automatic machine, like the dimensioning of the actuators and of the reduction gears, the vibrations and e?orts generated on the machine and on the load, the tracking errors during the motion execution. For these reasons, in order to understand and appreciate the peculiarities of the di?erent techniques available for trajectory planning, besides the ma- ematical aspects of their implementation also a detailed analysis in the time and frequency domains, a comparison of their main properties under di?erent points of view, and general considerations related to their practical use are reported.

Computer Aided Machining (CAM) software packages employ various types of algorithms to generate two dimensional trajectories along which a CNC milling machine must guide its cutting tool in order to remove material from a workpiece in a specifc pattern requested by the machinist. Commonly used standard 2D machining algorithms output the tool trajectory geometry (commonly referred to in other texts as toolpaths) as piecewise linear and circular curves in the Cartesian plane. The tool trajectories generated by those algorithms are dependent on a range of input parameters as well as a computer generated model that approximates a part or feature that needs to be machined -- all supplied by the user of the software. The main goal of such algorithms is to create a specifc pattern of tool motion that produces a desired finish on the part without gouging the work (ie. removing too much material where not intended) or leaving too much excess material. Typically the tool trajectory generation approaches do not take into consideration the kinematic capabilities and limitations of a CNC machine in order to generate time efficient tool trajectories. This is due in part to the sheer number of different types of machines available on the market - each with its own set of unique specifcations. In addition to that, the problem of generating a specifc pattern of motion that is at the same time optimized for another parameter, such as machining time, is of great complexity. Usually the motion pattern is the most important factor in trajectory generation and machining time reduction is in most cases limited to real-time feed rate (speed) optimization by the CNC machine processor at machining execution without any trajectory modifcations. The question related to machining time optimization of CNC machine tool trajectories which we are interested in exploring is whether it is possible for geometric transformations of tool trajectories to yield predictable outcomes in terms of machining time changes. If any such geometric transformation schemes could be identifed, they could help in simplifying the difficult process of global machining time minimization via tool trajectory modification. The goal of this paper is to design simple localized modification schemes of tangent-continuous piecewise linear and circular tool trajectory sections along with a method of machining time measurement that takes into account the kinematic constraints of tool speed and acceleration. We will then perform simple experiments involving machining time measurements using the proposed modification schemes and determine whether we are able to make predictions about optimal trajectory section configurations for each scheme.

Mobile robotics is a challenging field with great potential. It covers disciplines including electrical engineering, mechanical engineering, computer science, cognitive science, and social science. It is essential to the design of automated robots, in combination with artificial intelligence, vision, and sensor technologies. Mobile robots are widely used for surveillance, guidance, transportation and entertainment tasks, as well as medical applications. This Special Issue intends to concentrate on recent developments concerning mobile robots and the research surrounding them to enhance studies on the fundamental problems observed in the robots. Various multidisciplinary approaches and integrative contributions including navigation, learning and adaptation, networked system, biologically inspired robots and cognitive methods are welcome contributions to this Special Issue, both from a research and an application perspective.
