Obstacle avoidance via articulation
Journal of Robotic Systems, 1991AbstractThis article presents a practical implementation of the theory for articulation of spatial robots such as the PUMA and TRS type robots. The “Blueprint Algorithm” is introduced as a simple rule‐based planning algorithm in which the geometry of interference takes on the role of a basis in a collision‐free path planning process amongst obstacles ...

Obstacle avoidance in formation
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004In this paper, we present an approach to obstacle avoidance for a group of unmanned vehicles moving in formation. The goal of the group is to move through a partially unknown environment with obstacles and reach a destination while maintaining the formation. We address this problem for a class of dynamic unicycle robots.

1980
As Schevill (introduction to McBride, 1956) has pointed out, the original ideas about cetacean echolocation were based on observations of the porpoises’ ability to avoid obstacles in turbid waters. McBride (1956) noted that although porpoises (Tursiops truncatus) avoided fine mesh nets, by either rolling over the corkline or swimming directly through ...

Trajectory Generation and Obstacle Avoidance
IMA Journal of Mathematical Control and Information, 1987Manipulation systems with n degrees of mobility, modelled on a smooth n- dimensional manifold C (the configuration space), and smoothly mapped to W (the working space) are considered. The topology of the space of all continuous paths in W is discussed, using the methods of algebraic topology.

Visually-guided obstacle avoidance
ICONIP'99. ANZIIS'99 & ANNES'99 & ACNN'99. 6th International Conference on Neural Information Processing. Proceedings (Cat. No.99EX378), 2003The paper describes an indoor autonomous vision based obstacle avoidance robot system. The vision part of the system converts forward looking greyscale camera images into edge images using Canny edge detection. Both edge image and sonar ranging information is used as stimuli by the behaviours that make up the reactive part of the system.

Avoiding obstacles in cooperative load transportation
ISA Transactions, 2019This work deals with load transportation by quadrotors, when the load is attached to the vehicles through flexible cables. More specifically, two quadrotors are used to carry a single load, which is attached to both vehicles, through such kind of cables. The idea of using two quadrotors working cooperatively to carry the load is adopted to suppress any

Deformable trees - exploiting local obstacle avoidance
2011 11th IEEE-RAS International Conference on Humanoid Robots, 2011This work describes a hybrid trajectory planning approach for redundant robots, combining a local obstacle avoidance control framework with a global sampling-based planning component. The complexity induced by the high dimensionality of the configuration space is counteracted by shifting the global search to a low dimensional task space representation.

Obstacle Avoidance for Unmanned Aerial Vehicles
Journal of Intelligent & Robotic Systems, 2011This work is framed within the PITVANT project and aims to contribute to the development of obstacle avoidance techniques for unmanned aerial vehicles (UAVs). The paper describes the design, implementation and experimental evaluation of a potential field obstacle avoidance algorithm based on the fluid mechanics panel methods. Obstacles and the UAV goal
