Performance Evaluation of Mecanum Wheeled Omni-directional Mobile Robot

Mobile robots with omni-directional wheels can generate instant omni-directional motion including lateral motion without any extra space for changing the direction of the body. So, they are capable of traveling in every direction under any orientation to approach their destinations even in narrow aisles or tight areas. Especially, if a construction tool is combined to the mobile robot, it can b...

Using BELBIC based optimal controller for omni-directional threewheel robots model identified by LOLIMOT

In this paper, an intelligent controller is applied to control omni-directional robots motion. First, the dynamics of the three wheel robots, as a nonlinear plant with considerable uncertainties, is identified using an efficient algorithm of training, named LoLiMoT. Then, an intelligent controller based on brain emotional learning algorithm is applied to the identified model. This emotional l...

Direct Optimal Motion Planning for Omni-directional Mobile Robots under Limitation on Velocity and Acceleration

This paper describes a low computational direct approach for optimal motion planning and obstacle avoidance of Omni-directional mobile robots within velocity and acceleration constraints on the robot motion. The main purpose of this problem is the minimization of a quadratic cost function while limitation on velocity and acceleration of robot is considered and collision with any obstacle in the...

Development of a Step-climbing Omni-directional Mobile Robot

In this paper, we purpose a new holonomic omni-directional mobile robot that can move on not only flat floors but also uneven environment. A prototype robot can move in omni-direction, run on the uneven floors and slopes, and pass over large steps. The robot has seven universal wheels that have twelve cylindrical free rollers. We adopt a passive suspension system that enable the robot to change...
