Obstacle Avoidance Method for a Mobile Robot

by Pranab K Dan
"... This paper presents a new obstacle avoidance method for mobile robots. Obstacles in any number and with any quadrilateral configuration can be accommodated in this developed model. Robot movement is considered to be on a two-dimensional Cartesian grid. Unlike most of the methods reported, this one d ..."

Extending Obstacle Avoidance Methods through Multiple Parameter-Space Transformations

by Jose-luis Blanco, Javier González, Juan-antonio Fernández-madrigal , 2006
"... Obstacle avoidance methods approach the problem of mobile robot autonomous navigation by steering the robot in real-time according to the most recent sensor readings, being suitable to dynamic or unknown environments. However, real-time performance is commonly gained by ignoring the robot shape and ..."

Abstracting vehicle shape and kinematics constraints from obstacle avoidance methods

by Javier Minguez, Luis Montano, et al. - AUTONOMOUS ROBOTS , 2006
"... Most obstacle avoidance techniques do not take into account vehicle shape and kinematic constraints. They assume a punctual and omnidirectional vehicle and thus they are doomed to rely on approximations when used on real vehicles. Our main contribution is a framework to consider shape and kinemati ..."

and kinematics together in an exact manner in the obstacle avoidance process, by abstracting these constraints from the avoidance method usage. Our approach can be applied to many non-holonomic vehicles with arbitrary shape. For these vehicles, the configuration space is three-dimensional, while the control

A Comparison of Three Obstacle Avoidance Methods for a Mobile Robot

by Sachin Modi, Pravin Ch, Vidya Sagar Murty, Ernest L. Hall
"... Obstacle avoidance is one of the most critical factors in the design of autonomous vehicles such as mobile robots. The purpose of this paper is to compare and contrast three different methods for obstacle detection and avoidance. These include fixed mounting of sonar sensors, a rotating sonar sensor ..."

The Vector Field Histogram -- Fast Obstacle Avoidance For Mobile Robots

by J. Borenstein, Y. Koren - IEEE JOURNAL OF ROBOTICS AND AUTOMATION , 1991
"... A new real-time obstacle avoidance method for mobile robots has been developed and implemented. This method, named the vector field histogram(VFH), permits the detection of unknown obstacles and avoids collisions while simultaneously steering the mobile robot toward the target. The VFH method uses a ..."

Real-Time Obstacle Avoidance for Manipulators and Mobile Robots

by Oussama Khatib - INT. JOUR OF ROBOTIC RESEARCH , 1986
"... This paper presents a unique real-time obstacle avoidance approach for manipulators and mobile robots based on the artificial potential field concept. Collision avoidance, tradi-tionally considered a high level planning problem, can be effectively distributed between different levels of control, al- ..."

-lowing real-time robot operations in a complex environment. This method has been extended to moving obstacles by using a time-varying artificial patential field. We have applied this obstacle avoidance scheme to robot arm mechanisms and have used a new approach to the general problem of real-time manipulator

Research Article The Study of Cooperative Obstacle Avoidance Method for MWSN Based on Flocking Control

by Zuo Chen, Lei Ding, Kai Chen, Renfa Li

In order to reach the target, the nodes group should find a self-adaptive method to avoid the obstacles together in their moving directions. Previous methods, which were based on flocking control model, realized the strategy of obstacle avoidance
