Vibration is one of the most important resources of error in motion of tip of flexible robot manipulators. Although much work has been done in the design of controllers for flexible manipulators to follow a specified tip trajectory, it has been done a little work in trajectory planning itself. For redundant robot manipulators, trajectory planning can be accomplished with the aim of optimizing s...

This paper studies non-gaited, multi-step motion planning, to enable limbed robots to free-climb vertical rock. The application of a multi-step planner to a real free-climbing robot is described. This planner processes each of the many underlying one-step motion queries using an incremental, sample-based technique. However, experimental results point toward a better approach, incorporating the ...

Manual pre-operative planning is time consuming and depends mainly on the clinical experience of surgeons. It is helpful for automatic pre-operative planning and robotic surgery to explore the systematic methodology for operative environment analysis and understanding. Since shape segmentation, structure extraction and representation are fundamental to shape understanding, this paper aims to ex...

We consider the problem of planning motions of a simple legged robot called the spider robot. The robot is modelled as a point where all its legs are attached, and the footholds where the robot can securely place its feet consist of a set of n points in the plane. We show that the space F of admissible and stable placements of such robots has size (n2) and can be constructed in O(n2 logn) time ...
