From existing excavation machinery in the industry, the manipulator arm of a backhoe was chosen to do the modeling. In this study, a modeling of an excavation mechanism has been represented, where the purpose is to automatically excavate a parallelepiped-shaped foundation. Automation of excavation operations can be realized by an automatically controlled excavator system that is able to perform autonomously a planned digging work. Foundation excavation and general earthworks are activities that involve the machine operator in a series of repetitive and tedious operations, suggesting opportunities for automation through by the introduction of robotic technologies with subsequent improvements in the design and machine use, especially, in dangerous environments working.
