The utilization of satellites equipped with robotic arms is one of the existing strategies for Active Debris Removal (ADR). Considering that the time intended for on-orbit capturing manoeuvres is strictly limited, any given space robot should possess a certain level of autonomy. This paper is about the control of on-orbit space robots and the testing of such objects in laboratory conditions. The Space...
In the paper, an idea of a method of signal arrival direction estimation is presented. The influence of time error measurements on the usage of the method is described. An approach to the problem of an increase in the robustness of the method is proposed. The results of experiments are presented and discussed.
This article presents a robot for remote noninvasive medical examination. In particular, this robot allows a doctor to carry out an interview, an observation, an auscultation and an ultrasound examination, including echocardiography. The robot has been developed within the ReMeDi (Remote Medical Diagnostician) project funded by the European Union’s Research and Innovation 7th Framework Programme....
This paper considers the practical application of the RGBD Simultaneous Localization and Mapping (SLAM) techniques for localization of mobile robots. We attempt to answer the question: how the quality of the estimated sensor trajectory depends on the approach to RGB-D data processing in the SLAM system when RGB-D frames acquired on a real mobile robot are used. Experiments are performed on data obtained...
Reaction and driving forces may be non-unique in many robotic systems. This may pose a problem during robot design or its control synthesis. Hence, it is useful to detect which reaction or actuation forces are non-unique. Previously developed methods are designed for reactions uniqueness analysis only. These methods studied the constraint Jacobian matrix. The kinetostatics-based approach, presented...
This paper presents modeling and simulation of a tracked mobile robot for pipe inspection with usage of MATLAB and V-REP software. Mechanical structure of the robot is described with focus on pedipulators, used to change pose of track drive modules to adapt to different pipe sizes and shapes. Modeling of the pedipulators is shown with application of MATLAB environment. The models are verified using...
To apply a spinning hemisphere as a mobile robot drive is an unconventional idea. Equipping a mobile robot with two such hemispheres brings to life a device with absolutely novel properties. In this paper we derive kinematics models of a mobile robot with two driving hemispheres, analyse shortly their properties, and adopt a control algorithm designed to follow a path. There are two kinematics models...
The paper presents a set of soŌware tools dedicated to support mobile robot navigaƟon. The tools are used to process an image from a depth sensor. They are implemented in ROS framework and they are compaƟble with standard ROS navigaƟon packages. The soŌware is released with an open source licence. First of the tools converts a 3D depth image to a 2D scan in polar coordinates. It provides projecƟon...
This paper presents a navigation system structure for mobile service robots in the agent-based distributed architecture. The proposed navigation system is a part of the RAPP framework. The RAPP framework is an open-source software platform to support the creation and delivery of robotic applications, which are expected to increase the versatility and utility of robots. All key navigation tasks are...
The paper presents the method of determining the global orientation of links of the measuring arm by gauging the angles of the links relative to the vector of the gravitational and magnetic field using inertial sensors. A method of using Kalman filter to average the results is presented as a test on two-links measuring arm equipped with accelerometers and magnetometers placed on each of the links...
