Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...

Osteotomies around the knee address lower limb deformities that affect the leg posture and especially the knee joint. Knee arthritis is a very common age-related joint disease that can be treated with osteotomy, as an alternative to knee replacement by implants. The preoperative planning process is demanding and significantly determines the surgical out-come. The choice of the osteotomy type an...

Sampling-based motion planners are an effective means for generating collision-free motion paths. However, the quality of these motion paths, with respect to different quality measures such as path length, clearance, smoothness or energy, is often notoriously low. This problem is accentuated in the case of non-holonomic sampling-based motion planning, in which the space of feasible motion traje...

For high level path planning, environments are usually modeled as distance graphs, and path planning problems are reduced to com­ puting the shortest path in distance graphs. One major drawback of this modeling is the inability to model uncertainties, which are of­ ten encountered in practice. In this paper, a new tool, called U-graph, is proposed for environment modeling. A U-graph is an ex­ t...

The objective of my research is to design and develop a unique tool-path planning system based on Micrography. CNC milling machines are extremely accurate, and fully automated; they are used widely in manufacturing industries. Thus, the some improvement of their tool-paths can have a widespread impact in this world. Figure 1 shows that tool-path planning for a simple pocket leads to various dif...

Unmanned Aerial Vehicle (UAV) path planning is divided into off-line static path planning and real-time dynamic path planning. The former one is applied to the ideal situation that the terrain has been clear, and there is no unexpected situation in flight. Actually, however, the flight situation is very complex, we have to adopt real-time path planning based on off-line static path planning. To...

Motivated by fluid analogies, artificial harmonic potentials can eliminate local m in ima problems in robot path planning. I n this paper, simple analytical solut ions t o planar harmonic potentials are derived using tools f r o m fluid mechanics, and are applied t o two-dimensional planning among multiple moving obstacles. These closed-form solutions enable real-time computation to be readily ...

A vision based navigation (VBN) system is chosen as a basic tool to provide autonomous operations of a planetary rover during space missions. That means that the rover equipped with a stereo vision system and perhaps a laser ranging device shall be able to maintain a high level of autonomy under various illumination conditions and with little a priori information about the underlying scene. As ...

Path planning is the key task in the field of Robotics. The modelling environment and algorithm to find shortest, collision free path are the basic issues in the path planning problem of the robot motion planning. This paper presents a literature review of different path planning techniques in static as well as dynamic environment. Planning a path in static environment is easy as compared to dy...
