An unsolved ancient problem in position control of robot manipulators is to find a stability analysis that proves global asymptotic stability of the classical PID control in closed loop with robot manipulators. The practical evidence suggests that in fact the classical PID in industrial robots is a global regulator. The main goal of the present paper is theoreticall...

In this article, the method for increasing dynamic stability of quadruped robot is proposed. Previous researches on dynamic walking of quadruped robots have used only walking pattern called central pattern generator (CPG). In this research, different from walking generation with only CPG, a instinctive stability measure called landing accordance ratio, is proposed and used for increasing dynami...

Robotic football with humanoid robots is a multidisciplinary field connecting several scientific fields. A challenging task in the design of robot for AndroSot and HuroCup competitions realization movement on field. This study aims to determine walking pattern an impact its dynamic stability behavior. The proposed technical concept depends management mechanism, speed such factors as chosen appr...

Nowadays, there is still no robust solution to stabilize a humanoid robot while it is walking; all proposed solutions work only approximately for certain assumptions. This can be easily understood knowing that there is still no sufficient criterion that implies the stability of a walking robot. This project consists of finding a solution to keep a robot stable while it is walking implying the a...

The work presented here is a nonlinear approach for the control and stability analysis of manipulative systems in compliant maneuvers. Stability of the environment and the manipulator taken as a whole has been investigated using unstructured models for the dynamic behavior of the robot manipulator and the environment, and a bound for stable manipulation has been derived. We show that for stabil...

The paper presents the navigation of mobile walking robot systems for movement in non-stationary and non-structured environments. In the first approach are presented main elements for the successful completion of intelligent navigation. The wireless sensor networks (WSN), dynamical stability control, strategies for dynamical control and a Bayesian approach of simultaneous localisation and mappi...

In this paper we present the first part, part 1 of two, of a complete exploration and navigation methodology that enables a robot to safely navigate in an unknown environment. Reactive sensor-based navigation tasks and control laws are derived from the interaction between the robot and its workspace. The perception is performed by a two-dimensional laser range-finder mounted on the robot. React...

This article presents an adaptive control scheme based on position-force architecture to achieve the stability and transparency for teleoperation in unknown or varying environments. Without any knowledge about the parameters of the slave robot and environment dynamics, the proposed scheme guarantees the robustness to the parameter uncertainties of the master robot as well as the stability of th...
