This paper describes a robot manipulator system currently under development which learns assembling technique from observation of skilled worker’s demonstrations. The system is an application of EBL (Explanation-Based Learning) to the robot manufacturing domain. The system improves the operating capability of the robot manipulator through observing, analyzing the skilled worker’s assembling ope...

In industrial manufacturing rigorous testing is used to ensure that the delivered products meet their specifications. Mechanical maladjustment or faults often show their presence through abnormal acoustic signals. This is the same case in robot assembly the application domain addressed in this paper. Manual diagnosis based on sound requires extensive experience, and usually such experience is a...

Cultural evolution occurs through the transmission of cultural traits, and we consider the meme as the unit of cultural transmission. We construct an agent-based model representing the processes by which cultural transmission occurs and to link these to the community-scale phenomena arising from agent interactions. We base our model on small communities of e-Puck robots, and following work on m...

Industrial applications of mobile robots require the same behaviour for diierent types of autonomous robots. If this at a rst glance seems easy, it is in fact a rather complicated task as it means to adapt a system with a diierent mechanical model and thus diierent behaviours to a prescribed reaction to the environment. If in addition this goal should be reached automatically the complexity of ...

Isaac is a rule-based language for mobile robots currently under development at NMSU. A successor to Altaira, it replaces Altaira’s state-based rules and tile-based navigation with a more general geometric reasoning mechanism. The language uses the FuzzyCLIPS expert system shell as a reasoning backend.

due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. this situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. such...

This paper presents a method for detecting oscillations in behavior-based robot control networks. Two aspects are considered. On the one hand the detection of oscillations inside single behavior modules is based on analyzing the signal in the frequency domain using the Fast Fourier Transformation (fft). On the other hand tracing oscillations through the behavior network helps to evaluate its pr...

One emerging convention in video lectures is to show presentation slides with an inset video of the instructor’s head. Substituting a robot or a digital agent for the video of the instructor could radically decrease production time and cost; thus, the influence of a digital agent or robot on the learner should be evaluated. Agent-based alternatives for a talking head were assessed with an exper...

We propose a Case-Based Reasoning approach for action selection in the robot soccer domain presented in the 8th European Conference on Case-Based Reasoning (2006). Based on the current state of a game, the robots retrieve the most similar past situation and then the team reproduces the sequence of actions performed in that occasion. In this domain we have to deal with all the difficulties that ...
