Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape

چکیده
Abstract Over the recent years, there has been an increasing interest in autonomous systems. Consequently, problem of avoiding static and dynamic obstacles without human interference gained a lot attention. Avoiding collision, even completely environments, is significantly more challenging when vehicle subject to nonholonomic constraints. This paper presents reactive algorithm for collision avoidance dynamic, arbitrarily shaped obstacles, which suitable unicycle-type, vehicles. Unlike most methods, we consider exact shape obstacle, allows utilize any space that not occupied by obstacle. advantage over circle ellipse approximations, as they can lead overly conservative maneuvers. We provide explicit conditions under mathematically proven validate analysis numerical simulations.

3D Navigation and Collision Avoidance for nonholonomic aircraft-like vehicles
This paper extends the Navigation Function methodology to the case of 3D nonholonomic vehicles, both in single agent and multi-agent problems. The kinematic, nonholonomic, 3-dimensional model considered is chosen to resemble the motion of an aircraft by preventing any movement along the lateral or perpendicular axis, as well as preventing high yaw rotation rates. The discontinuous feedback cont...
متن کاملBenchmarking Collision Avoidance Schemes for Dynamic Environments
This paper evaluates and compare three stateof-the-art collision avoidance schemes designed to operate in dynamic environments. The first one is an extension of the popular Dynamic Window approach; it is henceforth called TVDW which stands for Time-Varying Dynamic Window. The second one called NLVO builds upon the concept of Non Linear Velocity Obstacle which is a generalization of the Velocity...
متن کاملTrajectory tracking with collision avoidance for nonholonomic vehicles with acceleration constraints and limited sensing
Nowadays, autonomously operated nonholonomic vehicles are employed in a wide range of applications, ranging from relatively simple household chores (e.g., carpet vacuuming and lawn mowing) to highly sophisticated assignments (e.g., outer space exploration and combat missions). Each application may require different levels of accuracy and capabilities from the vehicles, yet, all expect the same ...

Research into reactive collision avoidance for unmanned aerial vehicles has been conducted on unmanned terrestrial and mini aerial vehicles utilising active Doppler radar obstacle detection sensors. Flight tests conducted by flying a mini UAV at an obstacle have confirmed that a simple reactive collision avoidance algorithm enables aerial vehicles to autonomously avoid obstacles. This builds up...
متن کاملReactive collision avoidance for navigation with dynamic constraints
We address the problem of applying reactive navigation methods for collision avoidance to systems where the dynamics cannot be neglected: mobile robots with slow dynamic capabilities, or systems working at high speeds. Rather than embedding the motion constraints when designing a navigation method, we propose to introduce the robot dynamic constraints directly into the spatial representation. I...
