Position Control of a Mobile Robot through PID Controller

In this paper, the implementation and tuning steps of the PID controllers were proposed for the position control of a mobile robot with differential steering. The purpose of this robot was the participation in a European amateur robotics contest, the mobile robot being developed in the Engineering Faculty of Sibiu, Department of Industrial Machines and Equipment. After a brief introduction of the mobile entertainment robot, followed by description of the robot’s different components and traction principles, several principles of tuning the PID controller for the mobile robot are presented. The paper ends with some general conclusions based upon the results obtained from studying the research and considering all the ideas that were introduced.

Tema 2: The NAO robot as a Persuasive Educational and Entertainment Robot (PEER) – a case study on children’s articulation, categorization and interaction with a social robot for learning

The application of social robots as motivational tools and companions in education is increasingly being explored from a theoretical and practical point of view. In this paper, we examine the social robot NAO as a Persuasive Educational and Entertainment Robot (PEER) and present findings from a case study on the use of NAO to support learning environments in Danish primary schools.In the case study we focus on the children’s practice of articulation and embodied interaction with NAO and investigate the role of NAO as a ‘tool’, ‘social actor’ or ‘simulating medium’ in the learning designs. We examine whether this categorization is static or dynamic, i. e. develops and changes over the course of the interaction and explore how this relates to and affects the student’s motivation to engage in the NAO-supported learning activities.

Robotic Fish

<div class=""abs_img""><img src=""[disp_template_path]/JRM/abst-image/00260003/13.jpg"" width=""300"" />Structure of BREAM </span></div> Based on our robotic fish studies since 2003, this paper introduces a FPGA offline control underwater searcher (FOCUS) and a bream robot equipped with advanced mechanism (BREAM). The performance of the first FOCUS prototype, built in 2011, is now being improved. FOCUS has 2 cameras and fieldprogrammable gate arrays (FPGAs) with high arithmetic processing capabilities. The appearance of the FOCUS is so cute. The two FOCUS types now available are an autonomous underwater vehicle (AUV) and a remotely operated vehicle (ROV). BREAM, in contrast, is an entertainment robot prototype designed for Asutamuland Tokushima exhibition. BREAM has four joints based on analytical computational fluid dynamics (CFD) results showing that robotic fish with multiple joints achieve better propulsion performance than that with single joint. Two of the four joints are used for propulsion and two are used for turning the prototype. RC-FOCUS is also exhibited at Asutamuland Tokushima, together with BREAM. </span>
