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

A Novel Collision Avoidance Logic for Unmanned Aerial Vehicles Using Real-Time Trajectory Planning [PDF]

, 2014
An effective collision avoidance logic should prevent collision without excessive alerting. This requirement would be even more stringent for an automatic collision avoidance logic, which is probably required by Unmanned Aerial Vehicles to mitigate ...

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

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.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Multimodal trajectory optimization for motion planning [PDF]

The International Journal of Robotics Research, 2020
Existing motion planning methods often have two drawbacks: (1) goal configurations need to be specified by a user, and (2) only a single solution is generated under a given condition. In practice, multiple possible goal configurations exist to achieve a task.
