Design of user-friendly gripper to grasp both symmetrical and non-symmetrical complex geometrical objects. The proposed design is modeled, analyzed and simulated using Solidworks and Ansys software. The fabrication of the gripper should be using 3D printing technology with PLA. The operation and control will be carried out by using PLC, Pi boards and pneumatic technologies which enables gesture control, programming control and wireless control. The fabricated gripper will be tested with different objects for different applications. Performance results are properly validated by conducting different experiment ...

A modular system fluidity-based controlled expansion system that uses a gas to inflate an inner container quickly which then causes a fluid filled container to displace fluid causing expansion and deformation of the second container. A cable over the second container fixed at one end simulates tendon action. Each module is a system to itself requiring five volt logic and 16 volt 0.250A pulsed for energy input. The length of the power pulse determines the strength of movement. Single action units and double action units are available system can be scaled. Login input is a serial interface to tell the unit when to execute the command, allowing synchronization of ...

BACKGROUND:

Every year thousands of people lose body parts in accidents caused by different ways. Usually most of the other parts which are used to interact with computer are lost, but the eyes are still working, so why don't we use them? It doesn't mean if he or she doesn't have hands or he or she can't speak, and just because of this issue, he/she will go to bed and sleep the rest of their life. Why don't we find a way to allow their work to be carried out in the same way they used to do? For this purpose we figured that eyes are one of the biggest blessing we take for granted. We are trying to ...

Design Statement:

Design consists of the following main parts.
1. Panels
2. Steer Wire Rope / Steel Bars or Tubes
3. Lap Lock Joint
4. Earth Foundation Pillars
5. Free Foundation Pillars

Fabrication and Construction:
Install the main pillar, that will support its own panel’s (panel 1) four corners and two corners of other panels (panel 2 and panel 2’) that are lying on its both sides. Other two corners of each panel (panel 2 and panel 2’) will be supported by free foundation pillar of panel 3 and panel 3’. All the panels are attached to each other by lap lock joint that has been described in the image. These installation steps will be so on ...

Abstract: The proposed project concerns about a failure analysis of an electric aluminum alloy conductors damaged and broken for fretting fatigue phenomena induced by aeolian vibrations. Life of electric conductors is often reduced by various degradation mechanisms such as repeated bending, fluctuating tension, distortion, fatigue, wear and corrosion phenomena. However the main limiting factor of the electrical conductors is related to aeolian vibrations in the high frequency range (between 5 to 50 Hz). Conductor oscillations may lead to fretting fatigue problems caused by wind excitation, mainly in the suspension clamp regions, spacers or other fittings. The induced aluminium wire fracture imply a drastic reduction in the transmission line service. Vibration dampers are considered the most effective method to extend ...

Innovative concepts in lightweight engineering for automotive and aerospace applications increasingly trust in Multi-Material-Design. Additionally metal-plastic-combinations are often used in white or brown goods as well as within the furniture industry or in novel architecture concepts. A special challenge for multi material designs is the joining process. Existing technologies to join metals to polymers, like adhesive bonding or mechanical fastening, are ineffective regarding process time (adhesive bonding) or don’t applicate the forces optimally into the material (riveting, bolting). Moreover those technologies use supplemental materials like glue or rivets, which add weight and costs to the construction. The newly developed HPCI® (HeatPressCool-Integrative) tool appears like a spot resistance welding gun, which is widely used in car body engineering for metal ...

Background and Motivation
The conceptual manufacturing process of Hybrid Single Shot (HSS) has been developed by Clemson Composite Center to enable production of customized hybrid structures in one single operation. The metal-polymer sandwich structures provide superior properties such as high bending inertia, sound and heat insulation, and high energy absorption, which make them attractive for aerospace and recently automotive applications. Conventionally, 3D sandwich structures are produced either through a multi-stage manufacturing process or by forming a prelaminated blank. The former approach is not efficient enough for mass productions and the later one limited the forming geometry due to excessive shear tension and interlayer delamination. Hence, in this work, a new process is introduced in which a 3D sandwich structure ...

We live in a coastal town in India called Pondicherry famously known for its serene beaches and coastal activities. Over the years, as the city has developed, it has attracted more tourism, which has resulted in an increase of littering on the once clean and beautiful beaches. This problem is not unique only to Pondicherry but to hundreds of other coastal communities as well.

A recent study by National Geographic estimates that 9 million metric tons of plastic waste enters the world’s ocean from coastal regions. Not only are people affected by this, but this is causing havoc to marine life.

Our innovation, Maritime, is an amphibious rover that is scalable and low-cost which focuses on tackling this worldwide ...

Traceability in plastic production is difficult, so we wanted to develop a general solution which did not cause any extra headaches.

We aim to place barcodes on injection molded plastic products of any size, color and geometry, without adding processes or requiring materials or contamination of the part. The barcodes should be scannable by in-line vision or scanners, to be generally useful.

We create the master structures for our barcodes through MEMS lithography, creating detailled diffraction gratings intermixed with smooth reflective areas. This way, our barcodes achieve both diffusion and diffraction properties, creating very high optical contrast between microstructured and reflective areas.

The master structures are imprinted in a sol-gel material directly on steel parts, which is then sintered ...

Over the past few years, we have witnessed some of the most destructive forest fires on record. With the increasing threat of climate change, forest fires will start to become more frequent and more deadly. The Poseidon Sprinkler Defense System (PSDS) is the first and only defense needed to stop these destructive fires. Placed in strategic locations throughout the Western United States, in states like California, Arizona, Washington and Colorado, PSDS can be activated remotely upon detection of an incoming forest fires. The construction is primarily of aluminum, cast iron, copper, plastic, stainless steel, and steel alloys. A gearbox will be seated near the head of the unit will control the stream and water PSI.

Each unit would be ...
