abstract

this paper presents a parameterization method to optimal trajectory planning and dynamic obstacle avoidance for omni-directional robots. the aim of trajectory planning is minimizing a quadratic cost function while a maximum limitation on velocity and acceleration of robot is considered. first, we parameterize the trajectory using polynomial functions with unknown coefficients which transforms trajectory planning to an optimization problem. then we use a novel method to solving the optimization problem and obtaining the unknown parameters. finally, the efficiency of proposed approach is confirmed by simulation.

Delay Compensation on Fuzzy Trajectory Tracking Control of Omni-Directional Mobile Robots

This paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. Fuzzy logic control (FLC) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  On the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...

Optimal Trajectory Planning of a Mobile Robot with Spatial Manipulator For Spatial Obstacle Avoidance

Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...

Time optimal trajectory planning in dynamic environments

This paper presents a method for motion planning in dynamic environments, subject to robot dynamics and ac-tuator constraints. The time optimal trajectory is computed by rst generating an initial guess using the concept of velocity obstacle. The initial guess, computed by a global search over a tree of avoidance maneuvers, is then optimized using a dynamic optimization. This method is applicabl...

time-distance optimal trajectory planning for mobile robots on straight and circular paths

trajectories generally used to describe the space and time required to perform a desired motion task for a mobile robot or manipulator system. in this paper, we considered a cubic polynomial trajectory for the problem of moving a mobile robot from its initial position to a goal position in over a continuous set of time. along the path, the robot requires to observe a certain acceleration profil...
