Stability, Structure and Scale: Improvements in Multi-modal Vessel Extraction for SEEG Trajectory Planning [PDF]

, 2015
Purpose Brain vessels are among the most critical landmarks that need to be assessed for mitigating surgical risks in stereo-electroencephalography (SEEG) implantation. Intracranial haemorrhage is the most common complication associated with implantation,

Motion Planning of UAV for Port Inspection Based on Extended RRT* Algorithm

Journal of Marine Science and Engineering, 2023
A suitable trajectory in a port inspection mission is important for unmanned aerial vehicles (UAVs). Motion planning can help UAVs quickly generate an optimal trajectory that meets the constraints. The motion planning of UAVs is achieved in this paper as

Motion planning and irreducible trajectories [PDF]

2015 IEEE International Conference on Robotics and Automation (ICRA), 2015
We introduce a novel notion for lowering the dimensionality of motion planning problems: Irreducibility. Irreducibility of a configuration space trajectory τ means: We cannot find another configuration space trajectory τ′, such that the swept volume of τ′ is included in the swept volume of τ. The main contribution of our work is twofold: First, we show

Multi-criteria optimization manipulator trajectory planning [PDF]

, 2010
In the last twenty years genetic algorithms (GAs) were applied in a plethora of fields such as: control, system identification, robotics, planning and scheduling, image processing, and pattern and speech recognition (Bäck et al., 1997). In robotics the

Fast and Smooth Trajectory Planning for a Class of Linear Systems Based on Parameter and Constraint Reduction

International Journal of Applied Mathematics and Computer Science, 2022
Fast and smooth trajectory planning is crucial for modern control systems, e.g., missiles, aircraft, robots and AGVs. However, classical spline based trajectory planning tools introduce redundant constraints and parameters, leading to high costs of ...

ROBOT TRAJECTORY PLANNING

MM Science Journal, 2022
The paper deals with the kinematic analysis of the robot model. The matrix method of kinematic analysis is used. The robot mechanism is an open kinematic chain. The position, velocity and acceleration vector of the end point of the robot arm is determined in the Matlab program. Computer simulation is also performed in the MSC Adams program.
