What is Degree of Freedom (DoF)

The implementation of the European Project Semester at the University Politehnica of Bucharest has outlined the importance of developing soft skills through project-based learning for 21st century engineering learners. This chapter describes the project conducted by a team of four multinational students in 2018. It aimed to develop soft skills (language, written and oral communication, organization and time-management, research and inquiry, self-assessment and reflection, group participation, and leadership) as well as to foster the necessary professional tools for a smooth insertion into the labor market. The development of a 3D-printed robotic arm with IoT capabilities has proved a useful didactic approach in this sense and, at the same time, an efficient way to meet the future economic and technological demands of our changing world. The main goal was to design an affordable robot arm so that people could buy for any application desired.
