Improved RRT-Connect Based Path Planning Algorithm for Mobile Robots

open access: yesIEEE Access, 2021
Path planning plays a key role in the application of mobile robots and it is an important way to achieve intelligent mobile robots. Traditional path planning algorithms need to model environmental obstacles in a deterministic space, which is complex and ...

Path Planning Using Combined Informed Rapidly- Exploring Random Tree Star and Particle Swarm Optimization Algorithms

open access: yesIEEE Access
This study proposes a path planning algorithm that combines an informed rapidly-exploring random tree (RRT*) and particle swarm optimization (PSO) algorithms. The informed RRT* algorithm can build optimal pathways quickly.

Poli-RRT*: Optimal RRT-based planning for constrained and feedback linearisable vehicle dynamics [PDF]

open access: yes2015 European Control Conference (ECC), 2015
This paper proposes a Rapidly exploring Random Trees planning strategy (Poli-RRT*) that computes optimal trajectories in presence of vehicle constraints (e.g., differential and actuation constraints) without approximating the nonlinear dynamics, but relying on exact linearisation. In this way, the optimal control problem that is introduced to determine

RL-RRT: Kinodynamic Motion Planning via Learning Reachability Estimators From RL Policies [PDF]

open access: yesIEEE Robotics and Automation Letters, 2019
This letter addresses two challenges facing sampling-based kinodynamic motion planning: a way to identify good candidate states for local transitions and the subsequent computationally intractable steering between these candidate states.

Bidirectional Potential Guided RRT* for Motion Planning

open access: yesIEEE Access, 2019
Requirement for high accuracy and speed of grasping operation for motion planning is very important. Motion planning algorithms for avoiding obstacles in narrow channels play a vital role for robotic arm effectively operating grasp tasks.

Simulation of Rapidly-Exploring Random Trees in Membrane Computing with P-Lingua and Automatic Programming [PDF]

open access: yes, 2018
Methods based on Rapidly-exploring Random Trees (RRTs) have been widely used in robotics to solve motion planning problems. On the other hand, in the membrane computing framework, models based on Enzymatic Numerical P systems (ENPS) have been applied ...

Gene signatures characterizing driver mutations in lung squamous carcinoma are predictive of the progression of pre‐cancer lesions

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Lung squamous cell carcinoma (LUSC) is more aggressive than lung adenocarcinoma, and is most often diagnosed at an advanced stage. Here, the authors evaluated gene expression data from LUSC tumors and came up with gene signatures for 34 genetic abnormalities whose expression changes throughout different precancerous stages. Several of these

Evaluating Sleep Apnea: In‐Lab Versus at‐Home Recording Time and the Impact of Positional Disease

open access: yesThe Laryngoscope, EarlyView.
We evaluated the minimum recording time needed for in‐lab polysomnography (PSG1) and home sleep apnea test Type 3 portable monitoring (HSAT) to accurately reflect the full‐night apnea–hypopnea index (AHI) in patients with suspected obstructive sleep apnea (OSA).
