Online sub-optimal obstacle avoidance

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2000
This paper presents an online planner for suboptimal obstacle avoidance. It generates near-shortest paths incrementally by avoiding obstacles optimally one at a time. In known environments, obstacles are avoided in an order determined by a global criterion. In unknown environments, obstacles are avoided as they are detected by on-board sensors.

Obstacle avoidance in Down syndrome

Journal of Electromyography and Kinesiology, 2013
The ability to avoid obstacles requires to represent the properties of the obstacle, represent the location of the obstacle relative to the body and update these representations as the body moves. Individuals with Down syndrome (DS) often have trouble avoiding obstacles, leading to increased frequency of trips and falling.

Obstacle avoidance using PSO

2012 9th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2012
In this paper we present an obstacle avoidance algorithm based on Particle Swarm Optimization (PSO), which is a stochastic optimization technique. The PSO algorithm was modified in order to solve the proposed problem, in our case each particle of the PSO represents a new position, during the PSO algorithm each particle is tested to see if it represents

Time-optimal obstacle avoidance

Proceedings of 1995 IEEE International Conference on Robotics and Automation, 2002
This paper presents a method for generating near-time optimal trajectories in cluttered environments for manipulators with invariant inertia matrices. For one obstacle, the method generates the time-optimal trajectory by minimizing the time-derivative of the return (cost) function for this problem, satisfying the Hamilton-Jacobi-Bellman (HJB) equation.

Obstacle Avoidance for Manipulators

Systems Analysis Modelling Simulation, 2003
This article presents an obstacle avoidance approach for manipulators based on an obstacle avoidance path planning mechanism. Although the obstacle dealt with in the article is of the cubic type, it can be transformed to the spherical type as shown in the article, which has a simpler analytical description.
