The Rubik's cube is one of the most popular puzzles in the world. It is estimated that one in seven people have already played with the cube. There are several ways to solve the cube problem and some people solve without a technique help, however, this is a laborious and tiring practice. The existing methods range from the simplest to the most complex, and it influences the time that will be spent in the solution. A robotic solution can implement one or more of these methods to solve the Rubik's cube in an automatic way. Considering this, this work proposes a low-cost micro controlled system to solve Rubik's cube. This prototype is intended to be used in classrooms for the teachinglearning process improvement, and consequently also improve the students' performance in disciplines of logic and algorithms.

to bring assistance to rural areas of the United States. Although relevant, social and technological factors have limited the advancement of this type of service. However, the worsening of the health crisis caused by the coronavirus highlighted the importance of this type of tool and the need to improve them for the new social, economic and regulatory context. This work presents a new interchangeable face-to-face-telehealth treatment model mediated by an integrated system with cloud operation that combines traditional care with synchronous and asynchronous interactions regulated in Brazil. The system was validated in two medical clinics with the help of several health professionals. After two years of operation, 7,542 appointments were made and 3,677 consultations were recorded in electronic medical records, 1,434 asynchronous consultations were also performed, most of which were returns. Preliminary results indicate that the model is potentially viable for the various branches of health, even if the volume of synchronous consultations is still low.
