The thesis includes the plans as well as the realisation of an automated microprocessor-based device
for the production of food used as bait in carp fishing. This type of fishing bait production presents a
demanding and time-consuming task, thus it is sensible to automate it. The thesis covers the entire
process of constructing and manufacturing the mechanical components of the device. To build the
roller drive, an existing electric motor has been used. Initially, I have estimated its actual rated power
and afterwards calculated the maximum power needed to operate the device. The programme for
executing the automation process has been applied to the Raspberry Pi model B printed circuit board.
Using a PID controller I have controlled the rotation speed of the rollers by measuring the rotation
speed of the axis of the electric motor with a magnetic encoder, thereby controlling the rotation speed
of the motor through the constructed power circuit. Using the programming language Python3.x I have
developed a user interface for easier operating of the device. The conclusion presents further
possibilities for improving and upgrading the device.
