Echocardiography is the most commonly used imaging technique in clinical cardiology. Due to the high demand for this type of examination and the small number of specialists, there is a need to support the examination process through telemedicine. Moreover, specialist training can be supported by appropriate simulation systems. For (i) creating tail...

The paper presents the Embodied Agent-based Robot control system modelling Language (EARL). EARL follows a Model-Driven Software Development approach (MDSD), which facilitates robot control system development. It is based on a mathematical method of robot controller specification, employing the concept of an Embodied Agent, and a graphical modellin...

This paper presents a method of designing variable structure control systems for robots. As the on-board robot computational resources are limited, but in some cases the demands imposed on the robot by the user are virtually limitless, the solution is to produce a variable structure system. The task dependent part has to be exchanged, however the t...

Advanced robot control algorithms, that are based on sensor data fusion and a lot of processing, require high computational power. Hence, most of the modern robots have their own highly efficient computers. It makes the service and assistant robots costly and still unavailable for the most of the home users. In this paper the navigation system of t...

In the article the whole process of a manipulator controller development is presented. The controller is designed for the execution of various benchmark tasks in the field of service robotics. Initially, a set of system behaviors is presented as the base of the universal controller structure. For that purpose the embodied agent theory and the Syste...

In the article, a reactive torque–based hierarchical task–space control for a robot with multiple redundant DOFs is presented that is suitable to plan, validate and execute a humanoid upper-body motion in human oriented environment. The strategy consists of: (i) joint limit avoidance, (ii) self–collision avoidance using repulsive force fields with...

In this article the design procedure of a control system of a mobile robot with various modes of locomotion has been considered. The procedure is based on an embodied agent theory and focuses on the agent behaviours and transitions between them. The procedure was introduced to speed up and organize the whole controller development process. The effe...

In the article we propose a fast and cheap strategy of service robot kinematic parameters calibration. Our method is based on sensors (cameras in particular) that are already mounted on the robot and inexpensive markers, that are easy to fix on the robot arms. We developed the method to compute the impact of manipulator velocity on markers localiza...

The previous research on reactive torque control of redundant arms led to conclusion, that initial arm kinematic configuration is vital for task executed with the use of Cartesian impedance control. To provide that, in the article the control system is proposed with the two following modes of impedance control of redundant manipulators: Joint space...

In the article the robotic system behavior is investigated for the complex door opening task. The system consists of the 7-DOF KUKA LWR4+ manipulator, which is controlled in an impedance way and the BarrettHand gripper, which is controlled in a position way. The system utilizes multi-sensory feedback. The visual feedback is used to roughly localize...

Modern robotic systems are able to localize doors and its handle or knob, grasp the handle and open the door. Service robots need to open doors and drawers to autonomously operate in human environment. The mechanical properties of doors lead to incorporation of force and velocity constraints into the control law, to avoid the environment damage. In...

The paper presents an outline of the specification of a robot controller used in manipulation tasks requiring object grasping by a multi-fingered gripper and interaction with the environment. The specification assumes that the robot is represented as an embodied agent composed of real and virtual effectors and receptors and the control subsystem. T...

Opening a door with a robotic manipulator equipped with a gripper, is a vital problem in service robotics research. This paper presents an approach to opening a cabinet door with an impedance controlled 7-DOF redundant manipulator. A control system is developed that considers redundancy in order to maximise the manipulation capabilities of the mani...

Motor controllers are vital parts of robotic manipulators as well as their grippers. Typical, commercial motor controllers available on the market are developed to work with high level robot industrial controllers, hence their adaptation to work as a part of a scientific, experimental robotic system is problematic. The general concept of research o...
