The use of mechatronics engineering and control systems may not be conspicuous for the everyday inspector. Creating a device to demonstrate the working principle of such a system may be a desirable task, so theoretical knowledge can be strengthened via real life experiences. For this purpose many devices has already been created. One of the most popular and spectacular instrument to demonstrate closed-loop control algorithms is the ball balancing machine.
The ball balancing system in itself presents a challenging design problem. In the context of such an unconventional problem, the relevance of mechatronics design methodology becomes apparent.
In this diploma thesis designing, building and validating such a device will be presented. Different approaches to solve the given task were examined and an affordable yet reliable solution was prepared. According to the plans a prototype of the device was also built, so appropriate operation could be verified.
Presentation purposes of the final device were kept in mind, thus human interaction interfaces were added to improve its capabilities to demonstrate the working principles of a typical mechatronic device.
