INDUSTRIAL ROBOT

From wikipedia, the free encyclopedia

An industrial robot is officially defined by ISO[1] as an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes. The field of industrial robotics may be more practically defined as the study, design and use of robot systems for manufacturing (a top-level definition relying on the prior definition of robot).

Typical applications of industrial robots include welding, painting, ironing, assembly, pick and place, palletizing, product inspection, and testing, all accomplished with high endurance, speed, and precision.

Some examples of factory robots:

* Car production: This is now the primary example of factory automation. Over the last three decades automobile factories have become dominated by robots. A typical factory contains hundreds of industrial robots working on fully automated production lines - one robot for every ten human workers. On an automated production line a vehicle chassis is taken along a conveyor to be welded, glued, painted and finally assembled by a sequence of robot stations.
* Packaging: Industrial robots are also used extensively for palletizing and packaging of manufactured goods, for example taking drink cartons from the end of a conveyor belt and placing them rapidly into boxes, or the loading and unloading of machining centers.
* Electronics: Mass produced printed circuit boards (PCBs) are almost exclusively manufactured by pick and place robots, typically with "SCARA" manipulators, which remove tiny electronic components from strips or trays, and place them on to PCBs with great accuracy.[35] Such robots can place several components per second (tens of thousands per hour), far out-performing a human in terms of speed, accuracy, and reliability.[36]

* Automated Guided Vehicles (AGVs): Mobile robots, following markers or wires in the floor, or using vision[37] or lasers, are used to transport goods around large facilities, such as warehouses, container ports, or hospitals.[38] Early AGV-style robots were limited to tasks that could be accurately defined and must be performed the same every time. Very little feedback or intelligence was required, and the robots may need only the most basic of exteroceptors to sense things in their environment, if any at all. However, newer AGV's, such as the Speci-Minder[39], ADAM [40], Tug [41], and PatrolBot Gofer [42] qualify under the JIRA definition of "Intelligent Robots". They use some form of natural features recognition to navigate. Scanning lasers, stereovision or other means of sensing the environment in two- or three-dimensions is combined with standard dead-reckoning calculations in a probabilistic manner to continuously update the AGV's current location, eliminating cumulative error. This means that the "Self-Guided Vehicle" or SGV can navigate a space autonomously once it has learned it or been provided with a map of it. Such new robots are able to operate in complex environments and perform non-repetitive and non-sequential tasks such as carrying tires to presses in factories, delivering masks in a semi-conductor lab, delivering specimens in hospitals and delivering goods in warehouses.

I made this machine : Dissolution Tester
microcontroller based machine..
In this project, I have got some help from my friends

• ONE VIDEO

i have made pick & place type robot in 3 hour.

My collage project: Pick & Place type robot
My pick & place type robot can pick 200 gms material and it can place within 2ft radius. It was made from aluminum section, 5 gear motor (6-10rpm).

Project: collage event (Rob race)
My collage event rob-race car is made from some aluminum section, some fixing material, relay circuit and 2 gear motor (1200 rpm-12w).

Project: model plane
Here some photo & video of my testing model plane. I used 30,000rpm motor which is consuming 12w power. In first photo, Propeller & plane is made from plastic sheet. The plane speed: 2ft per sec on surface (not in air) because the plane was not made as perfect airfoil shape

Model aircraft are flying or non-flying models of existing or imaginary aircraft, often scaled down versions of full size planes, using materials such as balsa wood, foam and fiberglass. A vast array of designs are possible, from very simple gliders, to highly accurate scale models, some of which can be very large.

Models may be built either as static non-flying models, or as flying models (also known as aeromodelling). Construction techniques for the two are usually very different.

Try it with microcontroller circuit & paper printer & some component which will help to you make structure of Nail printer like acrylic, plastic sheet etc. Some photo of Nail printer & video

My last project: Hydroponics' Tomato

I started my project from 28-11-2005 with the seed of tomato. here some photo of plant. you can grow any plant in controlled environment. you have to need some component like water pump, pipes, pots, ph meter, and hydroponics nutrient. if you can make greenhouse for plant, that will be help to grow plant easily. for more information: Hydroponics.

Hydroponics is crop production with mineral nutrient solutions instead of soil containing silt and clay. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel or rockwool. A variety of techniques exist.

*************

Gericke originally defined hydroponics as crop growth in mineral nutrient solutions, with no solid medium for the roots. He objected in print to people who applied the term hydroponics to other types of soilless culture such as sand culture and gravel culture. The distinction between hydroponics and soilless culture of plants has often been blurred. Soilless culture is a broader term than hydroponics; it only requires that no soils with clay or silt are used. Note that sand is a type of soil yet sand culture is considered a type of soilless culture. Hydroponics is always soilless culture, but not all soilless culture is hydroponics. Many types of soilless culture do not use the mineral nutrient solutions required for hydroponics.

Billions of container plants are produced annually, including fruit, shade and ornamental trees, shrubs, forest seedlings, vegetable seedlings, bedding plants, herbaceous perennials and vines. Most container plants are produced in soilless media, representing soilless culture. However, most are not hydroponics because the soilless medium often provides some of the mineral nutrients via slow release fertilizers, cation exchange and decomposition of the organic medium itself. Most soilless media for container plants also contain organic materials such as peat or composted bark, which provide some nitrogen to the plant. Greenhouse growth of plants in peat bags is often termed hydroponics, but technically it is not because the medium provides some of the mineral nutrients. Peat has a high cation exchange capacity and must be amended with limestone to raise the pH.

Advantages

• While removing soil-grown crops from the ground effectively kills them, hydroponically grown crops such as lettuce can be packaged and sold while still alive, greatly increasing the length of freshness once purchased.
• Solution culture hydroponics does not require disposal of a solid medium or sterilization and reuse of a solid medium.
• Solution culture hydroponics allows greater control over the rootzone environment than soil culture.
• Over and under-watering is prevented
• Hydroponics is often the best crop production method in remote areas that lack suitable soil, such as Antarctica, space stations, space colonies or atolls, such as Wake Island.
• In solution culture hydroponics, plant roots can be seen.
• Hydroponics is excellent for plant teaching and research.
• No soil is required.
• Soil borne diseases are virtually eliminated.
• Weeds are virtually eliminated.
• Fewer pesticides may be required because of the above two reasons.
• Edible crops are not contaminated with soil.
• Water use can be substantially less than with outdoor irrigation of soil-grown crops.
• Hydroponics cost 20% less than other ways for growing strawberries.
• Hydroponics let the plants receive more sunlight.
• It is easier to replant and pick the strawberries because some hydroponics are towers that can hold 5 square pots which each pot can hold to 4 plants per each pot and the towers rotate.
• Many hydroponic systems give the plants more nutrition while at the same time using less energy and space.
• when using hydroponics the plants are less at risk of getting a root disease than plants that are grown in the ground.
• Hydroponics allow for easier fertilization as it is possible to use an automatic timer to fertilize the plants.
• Maintanence for this system is very low.

Disadvantages

Misconceptions

Hydroponics has been exaggerated as miraculous.^[1] There are many widely held misconceptions regarding hydroponics, and the following facts should be noted:

• Hydroponics will not always produce greater crop yields than with good quality soil.^[2]
• Hydroponic plants cannot always be spaced closer together than soil-grown crops (geoponics) under the same environmental conditions.^[3]
• Hydroponic produce will not necessarily be more nutritious or delicious than geoponics.^[4]
• Most hydroponic crops are grown in greenhouses or controlled environment agriculture.^[5]
• If timers or electric pumps fail or the system clogs or springs a leak, plants can die very quickly in many kinds of hydroponic systems.^[6]
• Hydroponics usually requires a greater technical knowledge than geoponics.^[7]
• For the previous three reasons, hydroponic crops are usually more expensive than soil-grown crops.^[8]
• Solution culture hydroponics requires that the plants be supported because the roots have no anchorage without a solid medium.^[9]
