Coordinated Dynamic Behaviors for Multirobot Systems With Collision Avoidance
IEEE Transactions on Cybernetics, 2017In this paper, we propose a novel methodology for achieving complex dynamic behaviors in multirobot systems. In particular, we consider a multirobot system partitioned into two subgroups: 1) dependent and 2) independent robots. Independent robots are utilized as a control input, and their motion is controlled in such a way that the dependent robots ...

Adaptive Speed Collision Avoidance For Dynamic Environments
2021 IEEE 17th International Conference on Automation Science and Engineering (CASE), 2021This paper presents a dynamic collision avoidance framework using predictive approaches. This predictive model exploits temporal and spatial characteristics of dynamic obstacles to predict future events thus avoiding collisions. To achieve this we implement a novel combination of two Poisson processes with independent outcomes and test this on a series

In order to satisfy the flight safety early warning requirements of UAV to the greatest extent and improve the safety and reliability of UAV operating in mixed airspace, with reference to flight interval standards, a cylinder static protection zone model of UAV is constructed to detect the flight conflict trend and near midair collision trend between ...

Dynamic Window Approach with Human Imitating Collision Avoidance
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021The autonomous navigation in the crowded environment is a challenging task due to the sensor occlusion and the complex nature of the abstract social interactions. And yet, humans are capable of navigating in such complex environment. In this paper, we propose an effective navigation method that combines the learning-based and model-based methods in a ...

Dynamic collision avoidance and constraint violation compensation
Nonlinear Dynamics, 1995This paper uses concepts in multibody dynamics, together with a collision detection algorithm to study the dynamics of collision avoidance. Obstacle avoidance of a mechanical system in motion is expressed in terms of distances, relative velocities and relative accelerations between potentially colliding bodies.

Spacecraft formation reconfiguration with dynamic collision avoidance
2013 IEEE Aerospace Conference, 2013In this paper we present three different solutions to the collision avoidance problem for spacecraft formations based on the Null-Space Based (NSB) behavioral control concept. In the first case, a constant sized sphere of safety area is centered on each spacecraft and obstacle, and the collision avoidance task is activated when this area is entered ...

Collision Avoidance by Utilizing Dynamic Road Friction Information
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020Advanced driver assistance systems require an autonomous emergency braking (AEB) system that considers varying tire-to-road friction conditions to estimate minimum emergency braking distance for collision avoidance. Conventional AEB systems, either do not consider the friction at all or assume constant friction, even though the actual road friction ...

Collision avoidance dynamics for optimal impulsive collision avoidance maneuvers
2017 8th International Conference on Recent Advances in Space Technologies (RAST), 2017This paper describes a method to calculate the optimal impulsive maneuver to avoid the collisions using Simplified General Perturbation 4 (SGP4) and Two Line Element (TLE). It also presents a rigorous analysis of the method to investigate the relative dynamics of the two colliding space objects assuming the encounter is instantaneous.
