In this book chapter a comparative assessment of modelling and control of mechanical
manipulator is considered. First, kinematic and dynamic modelling of wide range
mechanical manipulators comprising flexible link, flexible joint and mobile manipulators
considered. Then, open-loop optimal control problem is formulated to control of
obtained system. Finally, some applications of method including motion planning
maximum payload determination are illustrated through the computer simulations.
The number of different applications for RFID systems is increasing each year and various research directions have been developed to improve the performance of these systems. With this book InTech continues a series of publications dedicated to the latest research results in the RFID field, supporting the further development of RFID. One of the best ways of documenting within the domain of RFID technology is to analyze and learn from those who have trodden the RFID path.
Poincar´ made the ﬁrst attempt in 1896 on applying variational calculus e to the three-body problem and observed that collision orbits do not necessarily have higher values of action than classical solutions. Little progress had been made on resolving this diﬃculty until a recent breakthrough by Chenciner and Montgomery. Afterward, variational methods were successfully applied to the N -body problem to construct new classes of solutions.
Step 1 Use the show interfaces ethernet EXEC command to determine the
status of the router Ethernet interfaces. The presence of many cyclicredundancy-
check (CRC) errors but not many collisions is an indication of
Step 2 Check cables to determine whether any are damaged.
Step 3 Look for badly spaced taps causing reflections.
Step 4 If you are using 100BASE-TX, make sure you are using Category 5 cabling
and not another type, such as Category 3.
Abstract The work presented in this paper deals with the problem of the navigation of a mobile robot either in unknown indoor environment or in a partially known one. A navigation method in an unknown environment based on the combination of elementary behaviors has been developed. Most of these behaviors are achieved by means of fuzzy inference systems. The proposed navigator combines two types of obstacle avoidance behaviors, one for the convex obstacles and one for the concave ones.
Simulated annealing has been applied to a wide range of problems: combinatorial and
continuous optimizations. This work approaches a new class of problems in which the
objective function is discrete but the parameters are continuous. This type of problem arises in
rotational irregular packing problems. It is necessary to place multiple items inside a container
such that there is no collision between the items, while minimizing the items occupied area.
A feedback is proposed to control the next candidate probability distribution, in order to
increase the number of accepted solutions.
