Unconventional Drive System of a 3D Printed Wheeled Mobile Robot

摘要

The scientific literature reveals that recent trends in the construction of mobile robots investigate design and manufacturing directions at lower costs, including the printed 3D ones. This article presents the design of an autonomous four wheeled mobile robot with unconventional drive system. The design of the robot was performed in Inventor CAD system and it was manufactured by employment of the 3D print method from ABS. It is used a special control system based on Arduino 32. The drive of the four wheeled mobile robot is servo without potentiometer. The robot is equipped with two sensors for distance measurement. The control system of the mobile robot is programmed in C++ language. The tests showed correct operation of the control system and drive system at a robot speed around 350 mm/s.
