Planning Trajectories in Dynamic Environments Using a Gradient Method

چکیده
In this article we propose an extension for a path planning method based on the LPN-algorithm to have better performance in a very dynamic environment. The path planning method builds a navigation function that drives the robot toward the goal avoiding the obstacles. The basic method is very fast and efficient for a robot with few degrees of freedom. The proposed extension integrates the obstacle dynamics in the planning method to have better performances in very dynamic environments. Experiments have shown the effectiveness of the proposed extension in a very dynamic environment, given by RoboCup

Realtime Planning for High-DOF Deformable Bodies using Two-Stage Learning
We present a method for planning the motion of arbitrarily-shaped volumetric deformable bodies or robots through complex environments. Such robots have very highdimensional configuration spaces and we compute trajectories that satisfy the dynamics constraints using a two-stage learning method. First, we train a multitask controller parameterized using dynamic movement primitives (DMP), which en...
متن کاملDynamic Load Carrying Capacity of Flexible Manipulators Using Finite Element Method and Pontryagin’s Minimum Principle
In this paper, finding Dynamic Load Carrying Capacity (DLCC) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. The finite element method was employed for modelling and deriving the dynamic equations of the system. The study employed indirect solution of optimal control for system motion planning. Due to offline nature of the method, many diffic...
متن کاملMulti-Sensor Perception and Dynamic Motion Planning in City Environments
In this paper we describe a state lattice based motion planning approach, which we have successfully applied to large, cluttered, but quasi-static environments. Our approach produces smooth and complex maneuvers through the use of a multi-resolution state lattice, where the resolution is adapted based on the environment, and distance from the robot. We also describe a framework for detecting dy...
متن کاملRobot Motion Planning in Dynamic Environments
This paper presents a method for computing the motions of a robot in dynamic environments, subject to the robot dynamics and its actuator constraints. This method is based on the concept of Velocity Obstacle, which deenes the set of feasible robot velocities that would result in a collision between the robot and an obstacle moving at a given velocity. The avoidance maneuver at a spe-ciic time i...
متن کاملMapping Obstacles to Collision States for On-line Motion Planning in Dynamic Environments
This paper presents a representation of static and moving obstacles, using Velocity Obstacles (VO), for on-line planning in dynamic environments. Each obstacle is mapped to forbidden states by selecting a proper time horizon for the velocity obstacle. The proper choice of the time horizon ensures that the boundary of the mapped obstacle overlaps with the boundary of the set of inevitable collis...
