This paper presents a stereoscopic vision system for the mini-robot Khepera. The vision system performs objects detection by using the stereo disparity and stereo correspondence. The stereoscopic vision system enhances robot’s visual perception ability by grabbing stereo images and analysis 3D objects, while the robot doesn’t need to move. The simple principle of our stereo vision is the less d...

The goal of this work is to compare fuzzy, neural network and neuro-fuzzy approaches to the control of mobile robots. The rst part of this paper is devoted to the formal framework of fuzzy controllers. Results of an example of their use for a mobile robot are discussed. As an experimental platform, the Khepera mobile robot is used. The same example is studied using artiicial neural networks. Fo...

This work presents the application of a new hybrid neuro-fuzzy model, called RL-HNFP (Reinforcement Learning – Neuro Fuzzy Hierarchical Politree), in automatic learning of autonomous robots. This model provides an agent with intelligence, making it capable, by interacting with its environment, to acquire and retain knowledge for reasoning (infer an action). Promising results have already been o...

conclusions the combination of intravenous paracetamol 1 gr and ketamine 0.5 mg/kg resulted in an overall reduction in pain scores, decreased postoperative analgesic requirements, and lower agitation score compared with intravenous paracetamol 1 gr and tramadol 0.7 mg/kg for patients undergoing renal surgery. results postoperative pain scores were significantly lower in the pk group than in the...

In this paper we present a biologically inspired neural architecture for visual perception based on anticipation. The main goal of this work is to demonstrate, that anticipation is a central key to improve the perception performance of technical systems. The presented approach is able to increase the robustness of the perception process against noise or sensory dropouts. We demonstrate these pe...

A distributed mobile robot software application infrastructure is developed, improving integration and leverage between projects in a research environment. The resulting design includes a three layer CORBA based, service broker application architecture. A reference implementation and tests on B21r, LEGO Mindstorm and Khepera robots demonstrate the feasibility of the design.

This paper describes the technical implementation of the interface between the Matlab RealTime WorkShop c © and the Khepera c © robot operating system. Moreover, it shows how this tool is effective to quickly design, simulate and test controllers for autonomous robot. Finally, we discuss the feasibility of a object detection method based on acquired patterns of infrared sensors data.

pain in icu patients should be managed effectively and safely. fentanyl and paracetamol are used frequently in icu. however experience using iv paracetamol in the setting of critically ill patients is limited. we evaluated the analgesic effect and adverse reactions of intravenous paracetamol compared to fentanyl in icu patients with mild to moderate pain. forty patients in a general icu were ra...
