AISRA: Anthropomorphic Robotic Hand for Small-Scale Industrial Applications

Abstract

We describe the design of the multi-finger anthropomorphic robotic hand for small-scale industrial applications, called AISRA (Anthropomorphic Interface for Stimulus Robust Applications), which can feel and sense the object that it is holding. The robotic hand was printed using the 3D printer and includes the servo bed for finger movement. The data for object recognition was collected using Leap Motion controller, and Naïve Bayes classifier was used for training and classification. We have trained the robotic hand on several monotonous objects used in daily life using supervised machine learning techniques and the gesture data obtained from the Leap Motion controller. The mean accuracy of object recognition achieved is 92.1%. The Naïve Bayes algorithm is suitable for using with the robotic hand to predict the shape objects in its hands based on the angular position of its figures. Leap Motion controller provides accurate results and helps to create a dataset of object examples in various forms for the AISRA robotic hand, and can be used to help developing and training 3D-printed anthropomorphic robotic hands. The experiments in object grasping experiments demonstrated that the AISRA robotic hand can grasp objects with different size and shape, and verified the feasibility of robot hand design using low-cost 3D printing technology. The implementation can be used for small-scale industrial applications.

Virtual Training System for the Teaching-Learning Process in the Area of Industrial Robotics

“…(ii) Delta robot: they are mostly used for tasks of handling, sorting and classification of light materials where the development of this type of robots with high velocity and precision and light weight means that the links are made of flexible materials which cause vibrations as mentioned in the following table [8,9]. (iii) Anthropomorphic Robot: it has a very versatile configuration giving way to its movements having a similarity with the human arm, however the large amount of data set causes an erroneous prediction and at the same time there is an excessive consumption of energy of the links [10,11]. (iv) Scara Robot: this type of manipulator is widely used in production processes where repetitive tasks with high velocity and precision are required considering the manipulation of small loads [6]; the most relevant ones are: assembly, welding in the automotive area, adhesive placement, screwing, material distribution, part inspection and object transfer, which are present in sectors such as: pharmaceutical, aerospace, food, etc., i.e., in all automated systems [12,13].…”
