While activities aimed to attract the interest of secondary school students in robotics are common, activities designed to promote the interest of younger children are rather sparse. However, younger children from families with parents not working in technical domain have a little chance to be introduced to robotics entertainingly. To fill this gap, we propose a two-stage approach by organizing both programming and technology workshops for children by a volunteering group called “wITches”, followed by a robotic competition “Robosoutěž” aimed at children who are already familiar with basic concepts. We describe the proposed approach and investigate the effect of both stages on the number of students, their gender composition and their decisions of the field of study. The gathered data indicate that while the second, robotic competition stage is vital in persuading the children to proceed to study technology and robotics, the first, workshop stage is truly crucial to allow them to enter the field at all. In particular, for more than 70% of the participants, the workshops were the first opportunity to be introduced to robotics.

ROBOCONTEST is a final competition intended for the best students' teams (3-member) in the framework of motivation subject B3B35RO Robots (compulsory subject of bachelor study program Cybernetics and Robotics in the first year of study) and especially for the best high school teams that met in preliminary rounds of ROBOCONTEST FOR HIGH SCHOOL TEAMS participated in the last year final competition as well (in this year we prepare again four preliminary rounds). In this year we would like to arrange for higher propagation of the competition to increase the number of high school teams from whole Czech Republic.

ROBOCONTEST is a final competition intended for best 16 students' teams (3-member) in the framework of motivation subject B3B35RO Robots (compulsory subject of bachelor study program Cybernetics and Robotics in the first year of study). 16 best high school teams that met in preliminary rounds of ROBOCONTEST FOR HIGH SCHOOL TEAMS participated in the last year final competition as well (in this year we prepare again four preliminary rounds for maximal 128 teams).

ROBOUSOUTĚŽ is a final competition intended for best students' teams (3-member) in the framework of motivation subject A3B99RO Robots (compulsory subject of bachelor study program Cybernetics and Robotics in the first year of study) in which three departments participate - Department of Control Engineering, Department of Cybernetics and Department of Measurement. Six best high school teams that met in preliminary rounds of ROBOSOUTĚŽ FOR HIGH SCHOOL TEAMS participated in the last year final competition as well (in this year we prepare three preliminary rounds for 72 teams). In the last year 64 high school teams participated in the preliminary rounds (some teams were denied due to limited capacity) and six best teams competed with university students in the final competition for attractive prizes. For the first time in 5-year history high school team won the final competition. In this year we would like to arrange for higher propagation of the competition to increase the number of high school teams from whole Czech Republic.

Beginning study of technical branches is difficult and students are not interested. Challenging the basic subjects (analysis, linear algebra, physics, etc.), while the education necessary for career and very useful, but at the time when the students graduate this often does not know. Sometimes it finds out at the end stage of learning what the introductory courses are actually - and sometimes even regret that it is better to teach. We teachers make mistakes here as well: students are unable to adequately engage and provide them the answers before they come to their questions. To remedy this, we have introduced the subject Robots. It is not a traditional university course, but the subject of motivation. In his name we have deliberately used a "life form" that we have emphasized the creativity and playfulness. As we will see, our robots are really "live".

Začátek studia technických oborů bývá obtížný a studenty moc nebaví. Náročné základní předměty (matematická analýza, lineární algebra, fyzika apod.) jsou sice pro vzdělání ne-zbytné a pro kariéru velmi užitečné, ale v době, kdy je studenti absolvují, tohle často neví. Někdy zjistí až na konci studijní etapy, k čemu úvodní předměty vlastně byly - a občas i litují, že se je lépe neučili. My učitelé tady chybujeme také: nedokážeme studenty dostatečně zaujmout a poskytujeme jim odpovědi dříve, než přijdou jejich otázky. Abychom to napravili, zavedli jsme předmět Roboti. Není to tradiční univerzitní kurz, ale předmět motivační.

In this paper a full-car dynamic model with passengers has been designed. A four conventional quarter-car suspension models are connected to a get full-car model. Then braking, accelerating and steering influences are reflected, i.e. longitudinal and lateral acceleration are considered. Impacts of steering to lateral motion are discussed as well. Finally passenger models have been added. Usage of a vehicle model for simulation in many automotive control applications has great significance in money savings for test-beds, test circuits and other devices.

Final round competition, which was part of the introductory course ROBOT of the new bachelor program, Cybernetics and Robotics, held on Friday, 11/12/2009 from 15 hours in the Zenger's lecture hall at CTU in Prague at the Charles Square. In the course ROBOT student teams develop and programmed robots perform the specified tasks (the task follows the line and the task maze). For the final competition was selected task "MAZE". Each team was lent set containing basic set of the LEGO Mindstorms Education 9797, set of the technical parts 9648 (additional passive components), and network adapter 9833, but the way to build and program a robot, you had to find each of the teams themselves. Best eighteen teams from CTU FEE in Prague with two teams of robotic seminars from Gymnasium Voděradská measured the forces in the final contest for attractive prizes. Winning the robot, which one is quickly, passed separately through a maze. Entire finals competition was broadcast on-line via th

Study of technical subjects could be very difficult for new students entering the faculty with different background. Traditional study of theoretical disciplines without any clear relevance to "real" problems decreases motivation of many students, particularly those having difficulties with advanced mathematics. The core objective of our new subject Robots is to explore, in friendly way, students' independent thinking, and creativity and work in team. Although the theory is limited we believe that our students will eventually improve their theoretical knowledge as well. They start with something like child game trying to move robot from one place to another. Then, to succeed in more complicated tasks, they soon recognize that there is something behind the curtain and they start to ask how to solve the problems looking for a solution actively. If they reach this stage they are "trapped" - and become excellent and highly motivated students of control engineering.

Since the school year 2009/2010, new bachelor's program Cybernetics and Robotics offers compulsory subject A3B99RO Robots in the first semester of study. This is a completely new type of subject provided jointly by three Departments at FEE CTU: Control Engineering, Cybernetics, and Measurements. The course with a limited number of lectures to support required theoretical knowledge's is focused mainly on independent laboratory work. In lectures, the departments referred to above alternate with laboratory exercises running in parallel. Faculty assistants are supported in laboratory teaching by promising and experienced students strengthening the concept of "learning by teaching".

Automotive suspension system design is very important part of the passengers comfort and safety. In this article automotive active suspension with electric linear motor as an actuator is designed. Due to many reasons H-infinity control is used. This paper is focused on comparison of different controller designed for quart, half or full-car controller (and always used for ―full? car). Each controller configuration is simulated and then verified on the hydraulic quarter car test bed.

In this paper active suspension with linear electric motor has been designed. The active suspension is often hardly rejected for its big energy consumption. This contribution deals with direct real-time energy control in suspension system. The linear electric motor is used as an actuator. This motor can in specific situation generate the energy for next use. The H-infinity controller has been developed to improve car behavior, in particular passenger comfort and car stability. The second objective of the controller is to control energy distribution. Our submission is mainly focused on vehicle suspension, but it can be generalized to any kind of active suspension.

The main objective of this article is evaluation of two new controls methods of automotive active suspension system. At the beginning the H-infinity controller is developed and then it is, in the first case, modified at the cost of "optimality"deterioration (thus increasing H-infinity norm of closed loop) and, in the second case, there is several controller developed and switched according to the real road situation. Proposed control methods were evaluated during real experiments on test bed.

In the paper, energy recuperation and energy flow management in active automotive suspension systems with linear electric motors controlled using a proposed H-infinity controller to obtain a variable mechanical force for a car damper is presented. The main advantage of the proposed solution using a linear AC motor is the possibility to generate desired forces acting between the unsprung and sprung masses of the car, providing good insulation of the car sprung mass from the road surface disturbances. In addition, under certain circumstances using linear motors as actuators enables to transform mechanical energy of the vertical car vibrations to electrical energy, accumulate it, and use it when needed.

It is often assumed that if practical difficulties are neglected, active systems could in principle produce arbitrary ideal behavior. Using a simple linear two degree-of-freedom car suspension system model it will be shown that even using complete state feedback and in the case of in which the system is controllable in the control theory sense, there still are limitations to suspension performance in the fully active state. In control law design for active suspension system of vehicles it is demanded to prevent magnitudes of the road and load frequency responses from being too large. The paper aims to show that there are some frequency points and frequency ranges where the transfer functions have modulus strictly greater than one i.e. where road and load disturbance amplification occurs. On the base of the Bode integral theorems a proof will be given to show that the transfer functions must be greater in modulus to at least the same extend that it is less than one, when measured in terms of the area on a Bode magnitude plot. In such a case there is a possibility to shift frequency ranges where disturbance amplification occurs to a ”more advantageous place” or to make magnitudes lower spreading the frequency range. This theoretical conclusion will be demonstrated using a typical example.
