Avoidance of Multiple Dynamic Obstacles
this article is a continuation of the previous article called “Obstacle Avoidance in Dynamic Environment: a Hierarchical Solution”, which presented the concept for obstacle avoidance in dynamic environment suitable for mobile robot. The task of obstacle avoidance is divided in three principal groups: local, global and for emergencies. The global avoidance is here approached, in which the concep...
متن کاملDynamics of jamming avoidance in echolocating bats.
Animals using active sensing systems such as echolocation or electrolocation may experience interference from the signals of neighbouring conspecifics, which can be offset by a jamming avoidance response (JAR). Here, we report JAR in one echolocating bat (Tadarida teniotis: Molossidae) but not in another (Taphozous perforatus: Emballonuridae) when both flew and foraged with conspecifics. In T. ...
متن کاملAvoidance of Earth Obstacles for Intelligent Excavator
In this paper, we develop an algorithm for avoidance of earth obstacles using model-reference impedance control for autonomous excavator. There have been many research in the past regarding autonomous excavation, which were only concerned about position control, force control and path generation. However in order to apply the control system or algorithm to the actual autonomous excavation, it i...
متن کاملRedundant Inverse Kinematics System for Obstacles Avoidance
In this paper the authors relate to the robotic systems to avoid the obstacles while positioning end-effectors. A new strategy to on-line collision-avoidance of the redundant robots with obstacles is presented. The strategy allows the use of redundant degrees of freedom such that a manipulator can avoid obstacles while tracking the desired endeffectors trajectory. The strategy is based on the r...
متن کاملBats Broaden Sonar Field of View to Maneuver around Obstacles
Spotting a friend in a crowded room is a challenge, but we manage to do so by adjusting our visual spotlight of attention to search our surroundings. Animals that depend on other senses can adapt to similar situations. Egyptian fruit bats (Rousettus aegyptiacus), for example, use echolocation to orient inside their caves and to find fruit hidden in the branches of trees in Africa and the Middle...
