Dynamics and control of mobile manipulators is obviously a more challenging problem compared to fixed-base robots. Including a suspension system for these mobile platforms increases their maneuverability, but considerably adds to their complexity. In this paper, a suspended wheeled mobile platform with two 6-DOF Puma-type manipulators is used to manipulate an object along a given path. To apply...

Recently, robots have been used in many applications including industry and human ordinary life. Robots can make the human life easier by doing the dangerous works such as working in a toxic environment or by doing the hard works such as carrying heavy objects. In addition, robots can add more precision and repeatability in many tasks such as welding and assembly tasks. Human assistant robot (H...

A GA-based fuzzy controller design method is proposed for a two-wheeled mobile robot to independently control two velocities of its left-wheeled motor and right-wheeled motor so that the controlled robot can move fast and efficiently to the desired position. First, the kinematics model of the considered two-wheeled robot is described and a 4-input-and-2-output motion fuzzy control structure wit...

The research on two-wheeled inverted pendulum (TWIP) mobile robots or commonly known as balancing robots have gained momentum over the last decade in a number of robotic laboratories around the world. This paper describes the hardware design of such a robot. The objective of the design is to develop a TWIP mobile robot as well as MATLAB interfacing configuration to be used as flexible platform ...

The dynamic model of redundantly actuated mobile robots with powered caster wheels is derived based on vehicle dynamics. The contact stability problem of wheeled mobile robots is introduced and stable contact condition that characterizes the bounds of contact stability is derived. Sliding mode observer is proposed to estimate the robot velocity using wheel angular velocity and joint torque info...

This article presents a Java based 3D simulator for mobile robots called MoRoS3D. This application is able to simulate realistic motion of different wheeled mobile robots including dynamic behavior and collision detection. Typical sensors are also available in order to develop intelligent navigation applications. As this simulator provides CORBA interfaces for every active objects, applications...

In this paper, path planning of wheeled mobile robots is investigated in presence of environmental obstacles based on potential field method. To do this, nonlinear dynamic equations of the mobile robot are derived with the respect of its nonholonomic constraints. To avoid the obstacles during the robot’s motion, repulsive potential functions are used. By implementation of potential field method...

This paper presents the velocity kinematic modeling of wheeled mobile robots (WMRs) by applying the matrix coordinate transformation to every pairs of WMRs including wheeled pairs which were dealt with ad-hoc manners in the previous methodologies. A wheeled pair is not replaced with a planar pair and its kinematics is formulated together with those of lower pairs, even though there exists 2 DOF...
