Key component for Fusion Deposition Modelling (FDM) printers is the nozzle.
Diameter of the nozzle is a compromise between deposition rate and printing resolution. Large nozzle improves deposition rate, while high resolution requires small nozzle size.
Another critical issue is the surplus of material that keeps flowing out of the nozzle at the end of each deposition. Normally, a negative pressure is applied in the chamber to suck back the melted material. This leads to cavitation in the material, possible damages at the nozzle and generations of bubbles that are found in the further deposition.

In order to solve these problems the 3D SmartNozzle has an adjustable output hole. Thanks to this feature, adjusting the nozzle ...

Deep frying is not possible by method steam generator boiler. In the present conventional method for deep frying of commercially food manufacture unit, the utensils (vessel) are heated directly over the burner but in my innovative method, the vessel (jacketed kettle) is heated by the circulation (by ¼ H.P. motor pump) of hot oil. Its nobility is its energy efficiency, safety and quality control.

In this method cooking oil is placed into the jacketed kettle and it heated by hot oil (edible oil of 200°c) circulation through pipe line which is made of ‘Teflon’ or any other insulating medium which is heated by immersion heater into an another tank, and it’s temperature is regulated quite bellow of its smoking point. ...

A robotic inspection platform (“GeoRover”) is proposed for real-time and remote evaluation of highway culverts, drainage pipes, hillslopes, and other structures or features within a highway maintenance setting. The GeoRover is constructed of low-cost and readily available components for customized inspection purposes which are tailored to typical and specific highway maintenance needs; no expensive machining or elaborate construction and assembly is required, although control software must be written as this is not an off-the-shelf product. The GeoRover and selected onboard devices may be controlled using a standard hobby-grade 6-channel radio controlled (R/C) transmitter/receiver system, with the ability to operate in semi-autonomous mode if so programmed.

The intended applications include: visual inspection of culvert and pipe interiors with a ...

Large tonnage water cooled chillers are highly efficient, complicated machines and consume a lot of power. Each chiller is a compromise selection of heat exchangers, compressors with motors, and refrigerants to match the specific requirements of the customer. The complexity and customized aspect of these chillers makes nearly each one unique. Adding to that the geographic location and operating conditions (load and weather) for each installation insures that the owner has ‘one of a kind’ operation.

Therefore the chiller is difficult (if not impossible) to asses for operating efficiency and operational degradation on a timely basis. Periodic diagnostic checks are difficult to interpret and may include complicated sampling and lab tests of the refrigerant to show system degradation.

Today, high-rise buildings with glass, stone, metal, etc., facades during earthquake are considered potential threats to citizens and pedestrians passing by the buildings.

The buildings not only threaten the life security of their residents, but they also jeopardize the life security of passers-by as well if earthquake happens.

In the event of an earthquake, some part of building facade will collapse and passers-by who walk by these buildings will face a shower of rubble and glass.

Now, a security device can lower the threats substantially and it starts to work quickly in the event of an earthquake, so it protects the lives of pedestrians and passers-by.

Many buildings can be identified in crowded and busy ...

For decades work has been carried out to build robots similar to the human body structure but for this purpose a number of complex mechanisms are used. This new concept showcases a simple replication of human structure without a complex mechanism. This can be done with the help of a number of recent technologies like 4D printing, self-assembly, programmable matters and advancement in MEMS.

Recently researchers have made various self-folding sheets, self-assembling robotics block, shape changing materials with external stimulus. This advanced humanoid can be made combining all of this research. The basic principle is to use self-transforming materials at the position of human joints thus leading to similar motion as that of humans.

Climbing robots have been developed and are in use presently. But most of them have been designed and developed for climbing man-made structures such as vertical walls, structural frames and glass windows. Few climbing robots have been designed, for climbing natural structures such as trees, especially coconut trees for harvesting coconuts in specific. This paper proposes the design and development of a robot prototype A.R.C.H-1, with a novel idea of climbing, maneuvering and fastening mechanism, that actually climbs effectively and efficiently a pole, which simulates a coconut tree by its varying diameter and rough uneven surface. This robot operates by the reception of command from operator on the ground and he can view and select the coconuts to be ...

On agricultural farms, the harvesting of fruits like mango is still conventionally done by ‘handpicking’ methods from individual trees. It is obvious that nowadays decreasing labor populations due to a variety of reasons has led to the increase in labor costs, high input energy consumption and other problems. In order to solve this challenging task, a long term and high-tech alternative is required to boost the efficiency and profitability of the farmers. Hence an automated system that is low cost and easy to use is to be provided. For this purpose an Agribot has been made an alternative automated solution.

The Agribot, an automated harvester, illustrates a new emerging solution in the way of harvesting mangoes to the most pressing problem, ...

The Clothing Creator is automated process for apparel manufacturing, a machine to make clothing without direct human intervention. The Clothing Creator system goes from a bolt of cloth to a finish garment in a 45-second cycle that combines 3D fabric molding and ultrasonics to affect the cutting/seaming. Though the technologies have been used throughout the industry and inherent to thermoplastic materials, our innovation addresses the material handling challenge and a way to integrate them into a complete manufacturing system. The process would easily lend itself to functional work clothing, military uniforms, activewear, athletic apparel, medical disposables, haz-mat/cleanroom protective garments and the eventual development for mass-customization of clothing. This volume oriented, flexible mass production system for garment production will have ...

It has been observed that due to central locking of the door or due to the mistake of the concerned person (parent), when they leave their child in the car, that kid is unable to open the door when it is locked.

So if we introduce an oxygen sensor which senses the oxygen level which is connected to a PLC where there is set a minimum level if oxygen to be there for breathing, and when this happens will signal an alarm or will signal the window sliding mechanism to slide down by a given distance and again close or it can do both -- turn on the alarm and perform the function of sliding the window ...
