A wheeled mobile robot is subject to both holonomic and nonholonomic constraints. Representing the motion and constraint equations in the state space, this paper studies the feedback linearization of the dynamic system of a wheeled mobile robot. The main results of the paper are: (1) It is shown that the system is not input-state linearizable. (2) If the coordinates of a point on the wheel axis...

This paper shows the development of a mobile robot with expressive capacity for its use as tourguide robot in a museum. The system is composed of a wheeled platform and a robotic head which can perform different facial expressions: happy, sad, angry, frightened, astonished, etc. using a caricatured face and speech generation.

One of the major tasks of autonomous robot navigation elimination of robot errors. These errors are caused by imperfections in the design and mechanical implementation of robots. This paper presents experimental and statistical analysis of wheeled robots. The mobile robots consist of three differential drive robots that tested and moved in given trajectories and then the systematic errors of th...

Manipulators with mobile base are gaining momentum in the industry due to improved workspace and flexible adaptability to changes in the product designs. Although there has been research in this field for a considerable time, many issues are still to be resolved viz. obstacle avoidance, redundancy resolution for singularity avoidance, dynamic analysis of combined manipulator and a mobile robot,...

Omni-directional mobile robots have been popularly employed in several application areas. However, the kinematics for these systems have not been clearly identified, specially for redundantly actuated case which is common in omni-directional mobile robot such as Nomadic model. For such mobile robot systems, exploitation of redundant actuation as well as singularity analysis has not been extensi...

The paper considers a specific class of wheeled mobile robots referred to as mobile wheeled pendulums (MWP). Robots pertaining to this class are composed of two wheels rotating about a central body. The main feature of the MWP pertains to the central body, which can rotate about the wheel axes. As such motion is undesirable, the problem of the stabilization of the central body in MWP is crucial...
