Numerical Study of the Effects of a Hot Obstacle on Natural Convection Flow Regimes [PDF]
A numerical study was conducted for natural turbulent and laminar convection induced by a circular hot obstacle in two different positions, the heat obstacle is introduced at the inlet of the cylinder and inside the cylinder.

An Obstacle Avoidance and Trajectory Tracking Algorithm for Redundant Manipulator End
An obstacle avoidance algorithm was suggested in this study to handle the redundant manipulator’s end trajectory planning problem, with the accuracy of the end trajectory guaranteed to be within the projected error.

Application of Improved Blocked-Off Method to Simulate the Interacting Influences of Obstacle Shape and Wall Velocity on the Turbulent Mixed Convection Flow in a Trapezoidal Cavity [PDF]
In the current research, interaction influences of obstacle shape and top wall velocity on the hydrothermal behaviours of the turbulent mixed convection flow in a trapezoidal cavity are numerically simulated.

A classification of on-road obstacles according to their relative velocities [PDF]
The systems based on image processing have numerous applications in the domain of motion control of robots and autonomous vehicles. The current paper is oriented to the solution of the problem that precedes the implementation of automatic avoidance of the on-road obstacles—how to detect them, to track in the sequence of images, and to recognize which ...

Obstacle Boundary Point and Expected Velocity‐Based Flocking of Multiagents with Obstacle Avoidance
Obstacle avoidance is a key technology of multiagents flocking control. However, most existing research studies assume that the agent can obtain global information about obstacles and have specific constraints on the shape and boundary of obstacles, which easily limit their practical applications.

Motion planner of mobile robots for obstacles in occluded areas
Motion planning for mobile robots considering occluded obstacles is a navigation challenge in dynamic environments. If an obstacle suddenly appears from the occluded area, a robot might collide with the obstacle. This is the occlusion problem. Therefore,
