A drive unit comprising a two part-electric motor and a gear box coupled thereto is known. Gear box that is needed to reduce the output speed and thereby increase the torque. A disadvantage of the known drive unit is that it results in substantial costs, such as the gear box and its coupling to the motor exceeds two and more times the value of the motor itself. Furthermore, the presence of additional knots and details leads to the appearance of gaps, unevenness and noise at work, with an increase in details reducing the security of the product itself.
This is avoided by the proposed cyclo motor. In cyclo motor we have a unique combination of functions of the motor ...
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 ...
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 consists of the following main parts.
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 ...
MariTime: An Autonomous Amphibious Rover that uses Robotics to Efficiently Collect Waste in Coastal Ecosystems
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 ...
