Opis:
This paper presents a method based on Multiple Adaptive Neuro-Fuzzy Inference System (MANFIS) to regulate the handling force of a common object. The foundation of this method is the prediction of the inverse dynamics of a cooperative robotic system made up of two 3-DOF robotic manipulators. Considering the lack of slippage in the contact between the tool and the object, the object is moved. To create and feed the MANFIS database, the inverse kinematics and dynamic equations of motion for the closed chain of motion for both arms are established in Matlab. Results from a SimMechanic simulation are given to demonstrate how well the suggested MANFIS controller works. Several manipulated object movements covering the shared work¬space of the two manipulator arms are used to test the proposed control strategy. The simulation results indicate that the proposed control strategy is effective in regulating the handling force of a common object with varying desired forces, and does not require the use of force sensors on the object-tool contact.

Opis:
Mobile robots can be used to support humans in many applications ranging from simple process automation to complex autonomous inspection tasks. While walking robots are perfectly suited to cross rough terrain, they are not able to detect everything in their environment as certain areas might be occluded or too far away. This paper presents a method of enhancing the sensor capabili- ties of the walking robot LAURON IVc with the use of the lightweight aerial robot ARDrone. A simple method for localization of the ready to use UAV is presented using only color tags and the motor encoders of LAURON. The combination of these two robot types enhances the sensor range of LAURON greatly, while the ARDrone gains localiza tion information from LAURON that acts as a base station.

Opis:
Multi-robot systems have substantially increased capabilities over single-robot systems and can handle very large or peculiar objects. This paper presents a differential (incremental) motion planning algorithm for an m-robot system (m >or=2) to cooperatively transfer an object from an initial to a desired final position / orientation by rigidly holding it at given respective points Q[sub 1], Q[sub 2],..., Q[sub m]. One of the robots plays the role of a "master" while other robots operate in the "slave" mode maintaining invariant their relative positions and orientations during the system motion. The method employs the differential displacements of the end-effector of each robot arm. Then, the differential displacements of the joints of the m robots are computed for the application of incremental motion control. The algorithm was tested on many examples. A representative of them is shown here, concerning the case of three STAUBLI RX-90L robots similar to 6-dof PUMA robots. The results obtained show the practicality and effectiveness of the method, which, however, needs particular care for completely eliminating the cumulative errors that may occur.

Opis:
This paper proposes a new adaptive sliding mode control scheme for achieving coordinated motion control of a group of autonomous underwater vehicles with variable added mass. The control law considers the communication constraints in the acoustic medium. A common reference frame for velocity is assigned to a virtual leader dynamically. The performances of the proposed adaptive SMC were compared with that of a passivity based controller. To save the time and traveling distance for reaching the FRP by the follower AUVs, a sliding mode controller is proposed in this paper that drives the state trajectory of the AUV into a switching surface in the state space. It is observed from the obtained results that the proposed SMC provides improved performance in terms of accurately tracking the desired trajectory within less time compared to the passivity based controller. A communication consensus is designed ensuring the transfer of information among the AUVs so that they move collectively as a group. The stability of the overall closed-loop systems are analysed using Lyapunov theory and simulation results confirmed the robustness and efficiency of proposed controller.

Opis:
The paper describes the cooperative board game entitled THREE. The game is inspired by the Three Laws of Robotics. We show how this game may be used as an environment for exploring the ethical problems arising from human-robot interaction. We present the idea behind the game, discuss its cooperativeness and analyze the dilemmas encountered by players during the gameplay. We also present and discuss the results of the game evaluation.

Opis:
In this work we present an application of the concept of non-cooperative game equilibria to the design of a collision free movement of a team of mobile robots in a dynamic environment. We propose the solution to the problem of feasible control synthesis, based on a partially centralized sensory system. The control strategy based on the concept of non-cooperative game equilibria is well known in the literature. It is highly efficient through phases where the solution is unique. However, even in simple navigation problems, it happens that multiple equilibria occur, which incurs a problem for control synthesis and may lead to erroneous results. In this paper we present a solution to this problem based on the partial centralization idea. The coordinator module is incorporated into the system and becomes active when multiple equilibria are detected. The coordination method includes a ``fair arbiter'' for the selection of an appropriate equilibrium solution. Simulation studies of the proposed methodology were carried out for 2, 3 and 5 robots, and their results are presented.
