This paper presents a low-cost platform for controls
education that possesses some unique strengths:
The total cost of the system including the robot
chassis, motors, Raspberry Pi, and Arduino is $215.
The Arduino/Raspberry Pi combination provides
hard real-time control at update frequencies of 100-
150Hz.
The Raspberry Pi allows large amounts of data to be
collected and wirelessly transmitted for each test.
All of the software used is free and open-source.
The user interface for the students can adjust from
very simple to exposing all of the details of the
integrated mechatronic system. Students in a first
course on feedback controls can run tests using only
the simple web interface.tational and
