The Dept of Mechanical Engineering Biomechatronic Seminar Project Report defines the work objective to proper an artificial hand to copy the functions and appearance of the natural hand. The final aim of this report is to achieve entire actions of the natural hand.
The prosthetic devices and multitasking hand designs possess dependability and robustness and touching abilities are improved. It is showed that approaches and knowledge prospered are used to augment final accomplishment. Belgrade/USC Hand is an instance of artificial hand based on robotic approach.
Many articulated hands and robotic grippers are prospered like Utah/MIT hand and Stanford/JPL hand are obtained with wonderful results. These hands obtained better performance in copying human abilities and they are complex tools which need higher controllers.
The artificial hands act dispute problems for prosthetics applications utilized for working substitute in clinical practice. The Otto Bock hand includes one degree of freedom (DOF) and creates grip force to 100 N. Based on state of art analysis, the problems solved are deficiency of sensory information, lack of natural command interface, limited grasping capabilities, and unnatural motions of fingers while grasping.
The biomechatronic hand includes three fingers to offer atripod grasp, two identical fingers, and the thumb. The three fingers are required to entirely hold back the object. The hand includes two grasping functions. They are cylindrical grasp and tripod grasp.
This Dept of Mechanical Engineering Biomechatronic Seminar Project Report concludes that the artificial hand must sense like own hand of the user like the part of the body and extended physiological proprioception (EPP). It must offer the actions of natural hand such as grasping, touchable exploration, and manipulation.
