This paper presents a trajectory planning method that provides a continuity of position, velocity, acceleration and jerk. The method combines fifth-order and fourth-order polynomials in order to satisfy the continuity of jerk and give smooth accelerations on all segments of the planned trajectory. The proposed method was tested for movements of the(More)
This paper is concerned with simulation of floor shop layouts that may contain a number of robotic manufacturing cells and a number of Automated Guided Vehicles (AGVs) that commutate between dynamically determined starting and end nodes. We describe improvements of the AGVs pure pursuit path planning algorithm that were achieved by using a simulator for the(More)
This paper presents a dynamic routing method for supervisory control of multiple laser guided vehicles (LGVs) that are traveling within a layout of a given warehouse. In dynamic routing a calculated path particularly depends on the number of currently active LGVs' missions and their priorities. In order to solve the shortest path problem dynamically, the(More)
We present a laptop-based ultrasound training simulator and a novel method for creation of patient-specific training datasets. The simulator consists of a laptop computer, a peripheral probe interface device with an embedded three-degree-of-freedom orientation sensor, a virtual US probe, a virtual patient model, a simulated US brightness scan (B-scan).(More)
University of California at Los Angeles (UCLA) Center for Advanced Surgical and Interventional Technology (CASIT) researchers are developing an interactive image visualization pipeline with the ability to rapidly visualize and efficiently interact with patient-specific image datasets. The pipeline enables patient-specific image datasets acquired in a(More)
