This paper describes a method of mobile robot simultaneous localization and mapping (SLAM) based on laser range finder in unstructured environments. Considering drawbacks of the traditional iterative closest point (ICP) algorithm, matching laser range scans gets into local extrema when severe occlusions occur, the iterative dual closest point based on clustering (IDCP BoC) algorithm is proposed. Scan data are filtered and divided into clusters firstly, and then a procedure of reducing of data is conducted. The closest point (CP) rule is modified and dual closest point (DCP) rule is advanced when choosing the closest points. The reduced data is used for iterative computation before the error of two consecutive iterations' residual errors less than a preset threshold to speed up the algorithm, after that the data which is not reduced is used to guarantee the accuracy. Experimental results show that the method improves the accuracy of localization and mapping.

To fulfil the principle of low-cost and easy operation features, a new controll scheme is proposed for the LARM Hand in this paper. The new controller is composed of a high level PC-based control panel and a low level DSP control card and the two parts communicate with each other through RS-232. The PC-based control panel is software with which an operator can input control parameters, and additionally the operator can observe the changes of the force values and velocities of three motors in real time. The DSP controller is mainly used to control the motion of three motors by PWM signals as based on position control and force control. A position control method based on PID controller and a force control method based on PD controller both have been proposed in this paper. Simulations based on a simplified model are also carried out for these two methods.

this paper presents a novel method for mobile robot navigation by visual environments where there are obstacles in the workspace. The method uses a path selection mechanism that creates innovative paths through the workspace and learns to use trajectory that are more assured. This approach is implemented on motion robots which verified the shortest path via Quad-tree Decomposition (QD) and then used Voronoi Diagrams (VD(S)) algorithm we called (Q&V) algorithm. Based on the experimental data, we claim the robot's trajectory planned by Q&V algorithm is the better find andcontrol the roadmap is completely modeled and hasn't the localization errors. We show that even small modeled obstacles can cause large used from the preplanned path. Our complementary approach of path selection decreases the risk of path following and increases the predictability of robot's behavior.
In this paper we propose a behavior-based architecture, which can also be seen as a multi-agent architecture, to control a situated and embodied autonomous mobile robot, under a close sensing action relationship. Pre-...

In the present work, techniques of Model Predictive control (MPC), Multi Agent Systems (MAS) and Reinforcement Learning (RL) are combined to develop a distributed control architecture for Large Scale Systems (LSS). This architecture is multi-agent based. The system to be controlled is divided in several partitions and there is an MPC Agent in charge of each partition. MPC Agents interact over a platform that allows them to be located physically apart. One of the main new concepts of this architecture is the Negotiator Agent. Negotiator Agents interact with MPC Agents which share control variables. These shared variables represent physical connections between partitions that should be preserved in order to respect the system structure. The case of study, in which the proposed architecture is being applied and tested, is a small drinking water network. The application to a real network (the Barcelona case) is currently under development.
