Multi-robot systems control over many advantages over a single-robot managing system, including redundancy, coverage and flexibility. One of the important technical considerations in fielding multirobot systems for real-world applications is the coordinating the different units. The cluster based controlling technique using simplified specification and monitoring of the movement of mobile multi...

Service robots operating in domestic indoor environments must be endowed with a safe collision avoidance and navigation method that is reactive enough to avoid contacts with the furniture of the apartment and humans that suddenly appear in front of the robot. Moreover, the method should be local, i.e. should not need a predefined map of the environment. In this paper we describe a navigation an...

This paper applies acoustic principles and a novel scanning method motivated by acoustic flow to recognize retro-reflectors directly from sonar echoes while performing drive-by scanning. Right-angle corners and cylinders form specular retro-reflectors that produce strong echoes whose features can be easily identified. A multi-point sonar produces a point process whose density encodes the echo a...

This paper describes accuracy measurement method for high resolution miniature robot manipulators. The robot itself, measuring method and the results are presented. Parallel kinematic robot structures have by now seen as the most promising, due to their simpler and stiffer structure and easier miniaturisation. A robot using the direct drive method and direct high resolution feedback has been st...

In this paper, a worm-like micro robot designed for inpipe application with intelligent active force control (AFC) capability is modelled and simulated. The motion of the micro robot is based on an impact drive mechanism (IDM) that is actuated using piezoelectric device. The trajectory tracking performance of the modelled micro robot is initially experimented via a conventional proportionalinte...

The paper describes an advanced multisensor demining robot. The robot transport system is based on a simple structure using pneumatic drive elements. The robot has robust design and can carry demining equipment up to 100 kg over rough terrains. Due to the adaptive possibilities of pedipulators to obstacles, the robot can adjust the working position of the demining sensors while searching for mi...

The focus of this work is to design, develop and implement enhanced control and competitive robot arm thick and short cost. Design of four degree of freedom and talent of robot arm is to complete the accurate and simple tasks, such as optical materials processing, will be integrated into the mobile platform, as an assistant for the industrial labor force. Between the robot arm equipped with wea...

We have been developing new abilities of humanoid robot to realize proxy drives of a lift truck. Construction machines such as a lift truck play an important role in many tasks, but sometimes the environments are too hazardous for human operators. If a tele-operated humanoid robot can drive a construction machine, it can work at a dangerous place. This humanoid robot operator has two advantages...

This paper presents both the theory and the experimental results of a method allowing simultaneous robot localization and odometry error estimation (both systematic and non-systematic) during the navigation. The estimation of the systematic components is carried out through an augmented Kalman filter, which estimates a state containing the robot configuration and the parameters characterizing t...
