The main purpose of this thesis was to make an embedded system that would, based on user provided inputs from the user interface, autonomously control a circular saw for cutting logs. My work on this thesis includes the creation of software, a circuitry for the microcontroller to be able to control frequency inverters and an android application with which the microcontroller can be controlled using wireless Bluetooth communication.
The thesis firstly presents how the saw is and is yet to be constructed. The saw is, as of the time of writing, not yet completely finished. Then the problem of non-autonomous operation is presented. This was the main reason behind the development of an autonomous control system for the saw. Special care was taken when designing and implementing safety, both for the user and the machine itself. The microcontroller was programed in C++ language and the user panel was programmed in Java. The greater part of this thesis focuses on the problems and solutions in software, electric and mechanical implementation of the microcontroller. At the end of the thesis an industrial standard solution is presented, which was however not chosen due to economic reasons.
