Nowadays, the importance of the vehicles and its dramatic effects on human life is no secret. The use of trailers with multiple axels for transporting bulky and heavy equipment is essential. Increase in trailers axles which results increment of wheels, needs considerations in order to increase in transporting speed, maneuverability, safety, better control and path following accurately.  Therefo...

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...

A new missile midcourse guidance algorithm is proposed in this paper. It is a combination of sampling based path planning, Dubins’ curves and classical guidance laws. Moreover, a realistic interceptor missile model is used. It allows to anticipate the future changes of flight conditions along the trajectory, especially the loss of maneuverability at high altitude. Simulation results are present...

In image-guided brachytherapy (IGBT), accurate percutaneous intervention of needle and precise placement radiation sources are challenge tasks. In traditional prostate brachytherapy, needles are introduced through fixed, parallel holes of a template where the maneuverability of the needle is extremely limited. The accuracy and consistency of needle placement and seed delivery is subject to vari...

We introduce the concept of virtual stability, defined as a system’s ability to gain in flexibility and maneuverability by using self-monitoring in order to maintain itself in a state that would normally be unstable. After presenting a general description of virtual stability we look at a number of examples and outline a simple cellular automata model that is being used to explore virtual stabi...

The importance of mathematical and numerical simulation in marine engineering is growing together with the complexity designed systems. In general, a makes it possible to improve design, reducing working time costs production as well. this respect, implementation model for cycloidal propellers presented. Cycloidal thrusters are being increasingly used applications. Their best performance concer...

Correct models of complex flight, such as bat flight, have the potential to foster significant new discoveries in the biological evolution of flight. These models may also provide insight useful for engineering flight vehicles with increased maneuverability and in-flight sensing capabilities. To construct these models, one needs to understand and represent both the complex motion of bat wings i...

This paper demonstrates a “Grasp X” robot arm manipulation using a 2.5D disparity map and a Scale Invariant Feature Transform (SIFT) algorithm for recognizing the target object. The SIFT algorithm is applied after stereo segmentation, which reduces the matching time. Due to the high inaccuracy of the stereo disparity map and the maneuverability limitation of a twofinger gripper of the robot, RT...
