In this paper several interfaces for teleoperation of a mobile robot are described and analyzed. We consider teleoperation of a wheeled mobile robot when control commands are given by human operator through a haptic master device. Described human-robot teleoperation interfaces were tested by performing experiments. Main objective was to verify the role of different types of feedback information...

A stationary robot in an assembly line expects to execute all its hard-coded movements without any collision. Its recognition is limited to its tasks and the corresponding area of operation. In case of a failure an alarm is given and it stops working until a human being corrects the fault. The assembly robot does not react independently, which is the exact opposite to autonomous mobile robots. ...

We consider the problem of coverage and exploration of an unknown dynamic environment using a mobile robot. The environment is assumed to be large enough such that constant motion by the robot is needed to cover the environment. We present an efficient minimalist algorithm which assumes that global information is not available (neither a map, nor GPS). Our algorithm deploys a network of radio b...

The Fifth Annual Mobile Robot Competition and Exhibition was held in Portland Oregon in con junction with AAAI The competition consisted of two events Call a meeting and Clean up the tennis court The rst event stressed navigation and planning The second event stressed vision sensing and manipulation In addition to the competition there was a mobile robot exhibition in which teams demonstrated r...

Localization of mobile robots are important tasks for developing autonomous mobile robots. This paper proposes a method to estimate positions of a mobile robot using a omnidirectional camera on the robot. Landmarks for points of references are set up on a field where the robot works. The omnidirectional camera which can obtain 360 [deg] around images takes photographs of these landmarks. The po...

Localization, which is the ability of a mobile robot to estimate its position within its environment, is a key capability for autonomous operation of any mobile robot. This paper presents a system for indoor global localization of a mobile robot in a known environment based on visual and compass information. The system is based on colour detection and uses homogrphy between the image plane and ...

In this paper, different techniques/methodologies/strategies that are used in the field of mobile robot navigation have been reviewed forunknown environment is an important task for the new generation of several mobile robots. We consider the wheeled mobile robotsfor Path Planning, an autonomous robot and an obstacle and collision avoidance to be used in sensor based robots. We propose that dri...

This paper proposes the step-on interface (SOI) to operate a mobile robot in which a projector projects and displays a direction screen on a floor and a user specifies a button showing the selected movement by stepping or pointing. The HFAMRO-1 mobile robot has been developed to demonstrate the SOI’s potential (HFAMRO: “human-friendly amusing” mobile robot). The SOI of HFAMRO-1 consists of a pr...

An omnidirectional mobile robot is able, kinematically, to move in any direction regardless of current pose. To date, nearly all designs and analyses of omnidirectional mobile robots have considered the case of motion on flat, smooth terrain. In this paper, an investigation of the design and analysis of an omnidirectional mobile robot for use in rough terrain is presented. Kinematic and geometr...

In mobile robot applications navigation systems are of great importance. Automation of mobile robots demands robust navigation systems. This thesis deals with a few solutions on how to help a mobile robot navigate in an environment. Navigation systems using retroreflective beacons and applications relying on laser range finders are two different solutions to aid a mobile robot. The first type o...
