Abstract
The point of building this robot was to have it
successfully complete and tie a knot. The original
idea was to have the robot tie knots creating a
bracelet. Unfortunately, the process of tying a knot
alone was too much work to try and move on to an entire
bracelet. I had neither the time nor the insight to
build a flexible and usable 'arm.' I tested and
modified a design from the Lego Mindstorms book, but
found that I could neither open nor close the hand. I
continued to further modify the design to be able to
grab and let go of string but the result was extremely
bulky. Also I could not find a plausible and spaceconstrained
way to attach the gears to each of the
'fingers.' The conclusion that I drew was not that the
project was impossible but that it needed more time and
research.
Background
The idea for a robot that could neatly and
efficiently create a knotted bracelet became a reality
after my own experiences of personal pain and triumphs
over its creational process. Although the design is
merely knotting in a line some people have neither the
patience or ability to complete such a simple
masterpiece. This is when the idea for a bracelet
making robot was first manifested. It is being brought
to life for all those who can't or don't want to make
one themselves, hence, a robot to do it for them!
Unfortunately, two weeks is not enough to make a
full blown bracelet making robot. Instead my attempt
will be to make a robot that can successfully tie a
knot around a string. Which with more time would
eventually lead to an entire knotted bracelet. The
textile industry has prospered greatly since the age of
industry and invention. Cotton, silk, and various other
materials are processed and transformed into beautiful
fabrics and cloths which soon become clothes and
accessories. The flying shuttle was brought to
factories in 1733 by the inventor John Kay, improving
looms to enable weavers to get their work done even
faster. Soon after there came the spinning jenny, and
the water frame which became the first powered machine.
To be or Knot to be? 3
The inventions kept spewing forth until at last the
modern textile machine was born. Most of these are run
by computer with nowhere near the machinery. This
minimizes injury and ups the efficiency of production.
While my robot won't be the next big factory
design, it will make a simple but overly complicated
knot for a robot. In future years at COSMOS in the
robotics cluster, perhaps someone will see my design
and continue it, until it completely finishes an entire
The main point of this informative speech was how Medical Robots are changing modern medicine. The first point the speaker showed the audience is how the Medicial Robots help Maurine get a new kidney. The next point he tells the audience is how orderly robots are suppose to transport medicine, food and lab supply. The next robot he tells us about is the remote present robot. Remote present robot helps the doctor be with the patient even if they are not in the same hospital. The last robot he tells us about in his speech is the surgical robots. These robots are used in operating rooms around the world. The speaker did a great job of not speaking to fast or too slow, and he also made eye contact with his whole audience instead of looking down
This essay will talk about the Rube Goldberg project that I, Chandler Works have completed. The materials that I have used in this project is a car, dominos, a marble, blocks, and a bell. I used paper towel roles as the ramp so that everything can travel in its path. We also used little pieces of cardboard as a stopper, so the car or marble doesn't keep rolling after it hits the dominoes. At the end of the project, the dominoes are supposed to knock over and hit the bell to make it ring.
My artifact can be made in numerous ways and with lots of different material. For example a way to thread the knots is the Turkish Spread Knot. Carpenters do this by taking yarn and then wrapping it twice around two parallel threads and then the ends are drawn out between these the two threads. Another way is the Sinneh Knot or also called the Persian knot, what you do to make a Sinneh knot is you take the wool thread then you form a single wrap around the warp thread. One end will come out over one of the threads and the other will go over the next thread.
Because of technology which is defined as the organization of ideas for practical use, people are able to invent and produce machines that have made work less tedious. Twenty years ago, people use their hands to make coffee. But now, coffee machines are everywhere. Similarly, communication through mobile devices has replaced letter writing. In the fast-paced world, humankind continues to find ways in which they can perform simple tasks in just a snap. By the next fifty years, it will not be impossible to invent machines that would have a mind of their own. In fact, robots that can perform various tasks are already existing at the present.
One of the first and most prominent of these changes was in the textile industry. The textile industry was the staple of the industrial revolution. Before the industrial revolution, the textile, or more specifically cotton, industry was performed at home. It happened in a few steps. First, cotton was farmed and harvested. Then, the in home process began. Workers called “spinners” would take the cotton and form it into strands. These strands were the ...
Typical stairs consist of two basic components a tread, horizontal, and a riser, vertical. However, over time stairs begin to degrade causing slight warping in the trend. This shrinkage of the wood as well as weaken of the fastener between the riser and trend causes the two components to rub together, this creates an unpleasant squeaking sound.
The jigsaw teaching method is an important and influential style of teaching that was created to avoid any discriminations in the classroom setting. It was developed in the early 1970s by a man named Eliot Aronson, with the help of his students from the University of Texas, as well as the University of California. The jigsaw classroom is a cooperative learning technique originally created to reduce racial conflict among school children, but it has evolved to eliminate any form of competition in the classroom. It has been shown to promote better learning, improve student motivation, and increase enjoyment in the learning experience as a whole. Based off of past attempts of the jigsaw classroom, these teachers believe that there was a reduction in racial conflict, and an increase in positive educational outcomes such as an improvement in test scores. In addition to that, it has
I believe school students should be taught how to write in cursive as a required part of the curriculum. According to the article, "Cursive Is a Powerful Brain Tool", it is stated that, "Medical brain scans show that writting in cursive helps with fine motor-skill development and stimulates both the right and left part of your brain." Learning how to write in cursive doesn't only help your brain become more developed, it also helps students with dyslexia or those who have a reading disorder.
For my final project I decided to build a robot garbage truck that can drive by itself on a ?road? and pick up garbage. This garbage truck would also be able to distinguish from trashcans and anything else that might be in its place. This robot is a one-of-its-kind creation that has to my knowledge never been tried before. So I could replicate a real garbage truck as much as possible, I researched how garbage trucks work and how they have changed in the past 85 years of existence. I decided to create an arm unlike any garbage truck so far only because regular garbage truck arms need to be placed in a very small area to be able to lift up the trashcans. In seven days of work I was unable to finish creating my robot. I was only able to completely build the robot and partially program it. I believe that I made tremendous progress in building this robot in the time that I worked on it. This project has taught me so much on how to build a vehicle that replicates something useful for mankind.
The roots of the machine go back to at least the fifth century B.C. in China. In its most primitive form, it consisted of a pivoted beam with a sling at one end and ropes at the other. A stone would be placed in the sling and a team of men would haul the ropes, swinging the beam up into the air”1.
Robots are used in factories and even in people’s homes. So what if the Terminator film series got it right? Human workers, who work in factories, machineries, mills, everyday human controlled jobs like cash registers operators, are being replaced by robotic automation. This is a major problem for the everyday employee. Jobs that were once held by human workers, are now being replaced every day by robot “workers”.
Through sewing, you may express yourself, show your creativity and implement your ideas and fantasies. Moreover, this skill may lead to independence and self-sufficiency in the future.
Due to James Kay’s invention of the flying shuttle, there was a great imbalance in the 1730’s between weavers and spinners. Kay made it possible for weavers to quickly produce the amount of fabric that was demanded, but the spinners were still unable to make thread t...
Making a career out of sewing is a simple task, since the majority of people have an attachment to the idea of items being customized to their personal preference. Sewing is making, repairing, or attaching cloth by stitching the seams together with a needle and thread by hand or by a sewing machine. Although a seamstress is the one who makes and repairs clothing, they also conduct individual clothes fittings, alterations, and repairs. The primitive, ancient form of sewing was practiced by early man more than 20,000 years ago and has evolved from hand sewing into mechanical sewing. The idea of sewing all began when someone decided to use needles, which came from iron, to stitch together animal skin for clothing and blankets (Eve 1).
Even a small sewing thread failure leads to losses on investments in material, equipment, garment engineering, and labour. Sewing performance and seam quality could be influenced by sewing thread parameters, selection of proper thread and utilization of thread. Sewing threads is a unique type of yarn, engineered and constructed to pass through a sewing machine swiftly. The fundamental function of a sewing thread is to produce aesthetic and performance in stitches and seams (Coats 2003; Shaeffer 2000).
