Kinematics Analysis and Simulation of a New Type of Mechanical Excavator with Controllable Mechanism
A new type of excavator is introduced in this paper aiming at solving the problems the hydraulic excavator and traditional mechanical excavator (also called Electric Shovel) have respectively, which are hydraulic leaks and high maintenance cost of the former one and the lack of flexibility of the latter one. The analysis of the proposed novel excavator is carried out including: Degree-of-Freedom (DOF) of the new mechanism by constraint screw theory, inverse kinematics using the method of constraint equations, velocities and acceleration. A simulation study is proposed based on the analysis above. Results show that: the new type of mechanical excavator has the ability to achieve flexible trajectory output within its workspace.
