Abstract
This article presents the design, fabrication and testing of a novel vacuum based soft robotic gripper. This work included the fabrication of a cylindrical gripper via a 3D-printed mould, into which a combination of liquid silicone elastomer and curing agent was injected. The deformation behavior of the soft gripper was analyzed for different pressures using ANSYS software. The ANSYS results revealed that the pressure, material and size of the cavity inside the gripper are the important factor that affects the deformation of the soft gripper. Finally the grasping power and holding time of the fabricated gripper has been tested by grasping different objects including fruits, mobile phone, plastic bottles and stainless steel utensils. The validation findings demonstrate the gripping and holding capabilities of the proposed vacuum gripper, suggesting its suitability for various automation and industrial applications.
This publication proposes a definition and a classification of agile software development approaches and analyses ten software development methods that can be characterized as being "agile" against the defined criterion.

The study shows that agile practices improve both informal and formal communication, but indicates that, in larger development situations involving multiple external stakeholders, a mismatch of adequate communication mechanisms can sometimes even hinder the communication.

“X-Hinges” helps design and 3D print items like lamps and gloves with an interactive twist: automatically embedded sensors that perceive and adaptively respond to human contact.
StudentSim is a research system for evaluating and improving AI tutoring tools before they are tested with learners. It models how individuals may engage with tutors, giving feedback to improve tutor performance across subjects like chess, writing, and mathematics.
