Recent works on the control of wheeled mobile robots have shifted from the use of the kinematic model to the use of the dynamic model. Since theoretical results typically treat the inputs to the dynamic model as torques, few experimental results have been provided, as torque is typically not the input to most commercially available robots. Few papers have implemented controllers based on the dy...

The models of the robots include the kinematic and dynamic equations of motion. Trajectory tracking control problem of parallel wheeled ...

In this chapter, we present a sensor-based trajectory deformation process for nonholonomic robots. The method is based on infinitesimal perturbations of the input functions of the current trajectory. Input perturbation is computed in such a way that a an objective function decreases and that the trajectory initial and final configurations are kept unchanged. The method is then extended to docki...

This paper deals with the benefits and drawbacks of hexapods in Wheeled Mobile Driving Simulators. Therefore, a large and a small hexapod are considered and investigated in regard to their potential to reduce power, energy, and workspace demand of a Wheeled Mobile Driving Simulator. This is done by employing the hexapod for representing horizontal acceleration cues. Furthermore, the hexapod may...

Abstract: Self-balancing control is the basis for applications of two-wheeled robots. In order to improve the self-balancing of twowheeled robots, we propose a hierarchical reinforcement learning algorithm for controlling the balance of two-wheeled robots. After describing the subgoals of hierarchical reinforcement learning, we extract features for subgoals, define a feature value vector and it...

In this paper we propose a methodology for robust plane recovering from monocular images. The method is mainly based on the tracking interest points taken from a mobile robot’s camera. An efficient methodology for interest point detection, tracking and recovering has been implemented. The method proposed works in real time, and it is robust enough to deal with different undesired camera motions...

The subject of this paper is the motion control problem of wheeled mobile robots (WMRs) in environments without obstacles. With reference to the popular unicycle kinematics, it is shown that dynamic feedback linearization is an efficient design tool leading to a solution simultaneously valid for both trajectory tracking and setpoint regulation problems. The implementation of this approach on th...

Positioning of mobile robots basically calculated using odometry information. Odometry from the wheel’s encoder is mostly used for simple and inexpensive implementation for determining the relative localization of a mobile robot. This paper deals with the estimation of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of par...

A motion control and the corresponded strategy to realize cyclic ball passing motion in robot soccer games are presented in this paper. By this strategy, multiple mobile robots kick the ball in tum with high speed while they adjust or change their formation. The ball-kick controller is to drive the robot to an adequate position with a prescribed velocity in a fixed finite time. After kicking, t...
