Design and implementation of encoder unit
Kirchner, Tomáš ; Sova, Václav (referee) ; Spáčil, Tomáš (advisor)
The aim of the thesis is to implement an absolute magnetic encoder unit as a sensor measuring the angle of rotation of a DC engine on a ballbot, which is part of the BB-8 project at the mechatronic laboratory. It describes the principals and limitations of a magnetic encoder technology, also the design of printed circuit board for the sensor and the engine housing. Testing functionality of the encoder at Raspberry Pi was part of the work as well as creating SPI communication with a master microcontroller PIC. Furthermore an accuracy of the angle of rotation sensing was measured for different inaccuracy of a magnet position to the sensor.
