Preliminary Design
Though my prototype serves the same function as the production version will, the
production version will visually be a totally different robot. While testing my robot, I identified
numerous problems the design of my prototype that could not easily have been fixed. To fix
these problems, completely new materials will be required as well. Since it is likely that my
robot would be used by disabled people(most probably with poor motor control), it is necessary
that the robot is durable, and safe to use. The outer shell will be made out of aluminum, since it
is a relatively light and cheap metal. It is important that the robot weighs as little as possible, so
it does not require large motors, which will increase the cost and overall size of the robot. Since
aluminum often has sharp edges, the robot will be covered in padding to reduce the risk of injury
from operation, and act as a shock absorber if the robot is struck by an object or dropped.
The other, more obvious difference will be that the real version of my robot will
be controlled by a circuit board, instead of an RCX control brick. This will allow the use of
many different sensors and motors, and surprisingly will also be considerably cheaper. The other
important difference is that the real version of my robot will write using a robotic arm instead of
moving as whole. However, the robot will still be able to move for convenience. Just like the
RCX, it will have computer connectivity, except that it will have a wired connection for higher
speed and lower cost.
Materials and Prototype Design
Parts List:
Many standard Lego parts
3 Motors
8, 16, 24, and 40-tooth gears
One Touch Sensor
1 RCX
1 Black Crayola Marker
My robot is divided into 3 basic parts (not including the RCX brick). Below the RCX,
brick, I have the standard wheel structure with the standard gear configuration. There are eighttooth
gears on both motors, connected to the wheels with forty-tooth gears for maximum torque.
I have also used the standard medium-sized, flat tires in the front since they perform well.
However, there are no rear wheels; Instead, the back of my robot is supported by bare forty-tooth
gears, which has caused no problems. The reason why I have this odd wheel setup is because I
originally built legs for my robot, but switched to wheels after finding that the legs had
extremely little traction.
The second, and most complicated part of my robot is the marker-lowering mechanism.
This mechanism is comprised of a motor, a very large set of gears, and a platform that slides on
Gears are considered wheels with teeth, sometimes called a cog. When the gears come together they are able to make things turn. You need to have at least two cogs to do any work with a gear. Gear come in many different sizes which help them do work. The purpose for gears is to be able to motion from one moving object to another. Gears are used for many reasons such as to increase or increase the rotational speed, to move rotational motion to a different axis, or to keep the rotation of two axis moving at the same time. There are many different types of gears used for different things examples of some would be spur gear, helical gear, worm gear, internal gear etc. Spur gears are one of the most commonly used gears since they’ve been around the longest. Spur gears have teeth that run vertical to the face of the gear. Helical gears are actually similar to the spur gear the difference between them is that the teeth are not perpendicular to the face of the gear, and tend to run smoother due to the larger amount of teeth it has. (Gears and stuff, 2006)Worm gears are u...
The materials in prosthetic limbs have always evolved along side technology, usually changing for the better. Prior to the development of electronics and plastics,
Some would say the attempt to make a robot is an attempt to 'play god' and to recreate man. Others would argue that robots might become so intelligent that they would take over and replace humans. There is no better example of this than the movie Terminator, which begins with a world ruled by machines who are trying to kill the remaining human population. The actual field of robotics however, has produced many products which we take for granted. The clock is a household item that was developed in the beginning stages of machine ...

Nowadays, technology is a dominant feature in the lives of people around the world. Most of daily life activities involve the use of technology which is expanding every day through scientific innovations. However, such innovations do not always occur in every part of the world, but mostly in technologically developed countries, such as South Korea, the USA and Japan. Presently, the development of robotics science has become a subject of considerable attention in those countries. According to Weng, Chen and Sun (2009, 267), “Technocrats from many developed countries, especially Japan and South Korea, are preparing for the human–robot co-existence society that they believe will emerge by 2030.” The word “robot” was introduced in the beginning of 1920th by the Czech playwright Karel Capek from the Czech word “robota”, meaning “forced labor” (Robertson 2007, 373). According to Robertson (2007, 373), robot, in practical usage, can be defined as an autonomous or semiautonomous device that is used to perform its tasks either controlled by human, fractionally controlled and with human guidance or regardless of external actions that are performed by people. Regrettably, the majority of robots in the past centuries could not operate without human control and intervention. However, the progress in robotics over the past few decades enabled humanity to achieve soaring results in creation of autonomous humanoid robots.
It is a shared truth that humans often tend to think of robots as nothing more than computer machines made of objects like metal, plastic, silicone and computer chips. However, in truth, a robot’s general purpose is more complex than some know. In order for a robot to function, it must carry out a set of arithmetic or logical operations, and programming the specs is difficult task that could take years to finish depending on the purpose of the robot.
When people think of robots, an image of a mechanical, stiff, talking, moving, human-like machine might come to mind. Robots are, in fact, computerized machines that are ultimately utilized to simplify larger scale tasks. They include control machines, computer controllers, or microprocessor based automated systems just to name a few. The ultimate goal of industrial engineering is to expedite processes; therefore, with such developed and modern technology, the manufacturing process is more efficient, cost effective, and there is almost no human error. With all its benefits the automation and robotics movement has made way for new fetes and greater prospects in economic terms for large-scale firms.
Robots are made to run without flaws and can outperform the average worker. This is because there are fewer employees working that need to get paid. This is not a good thing as it might seem. In China, robots almost completely replace human workers to save money.
...g to a bank to deposit a check, it can be done through a bank app on a smartphone or tablet where you take a picture of a check and it is deposited in your account. This app is unnecessary and we are able to do without it, but it saves time and money. Auto Mee S is a device that is now popular in Japan. It is a smartphone vacuum. This device was created to keep screens smudge-free. It replaces the traditional microfiber cloth. Time magazine released an excerpt talking about newly created robots. Japanese developers introduced a robot that can win at rock, paper, scissors. Brazilian students developed a Rubik’s Cube solver. Cornell and University of Chicago students collaborated and developed a dart thrower. These robots are all useless and there is really no need for them in society, it is just merely a source of entertainment, or just makes life that much easier.
Robots are machines that can do the work of a person and that work automatically or are controlled by a computer (Merriam-Webster, 2014). The Robot Institute of America (circa 1979) defines robots as “a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks” (Branwyn, G.). The Japanese Industrial Robot Association (JIRA) has classified robots based on the following: manually operated manipulators, sequential manipulators, programmable manipulators, numerically controlled robots, sensate robots, adaptive robots, smart robots, and intelligent mechatronic systems (Branwyn, G.). Robots have been improved over time and have proven to be efficient because the computer is controlling them. The history of robots goes as far back as the Ancient Greeks and Romans for the use of toys, tool...
I don’t think there is any reason for these robots to have every ability that a human does. There is no way they are going to have the intelligence a human does. Artificial Intelligence is just going to bring more harm into our communities. We can’t trust the robots doing the “everyday” human activities, they are going to lead to unemployment, and will lead to laziness causing more obesity.
Each of the six basic styles of robot used in industry today were designed with different applications in mind. Some of the robots were designed for assembly, others are more suited for simple pick and place applications, while a select few are capable of carrying heavy loads over a large area.
Robots always had a special place in mankind’s heart. There has always been an aura of mystery and discovery surrounding them. What is a robot? Wikipedia defines it as “an automatically guided machine which is able to do tasks on its own.” That is a good definition of a robot, but there are few exceptions too.
In today's society, robots come in different types and qualities, and robots’ use was mainly in the laboratories and factories; however, that has drastically changed where their uses are changing at a high speed. In addition to that, they have spread throughout the world. The main function of robots is to replace the work that people used to do, or perform tasks that man cannot. A robot is a mechanical or virtual device that uses a computer program, or electronic circuitry, to carry out its functions. In modern science, robotics refers to the study of robots is robotics, which deals with designing, constructing, operating, and using robots and computer systems for controlling and processing information and providing feedbacks. However, as much as robots replace human labor, individuals or organizations can use them in dangerous environments that might be harmful and beneficial to humans. Therefore, to understand the logic behind the creation of robots, one should learn the pros and cons of robotics, in the current society. This is because people are using this technology without having a deep understanding of its effects. However, an objective evaluation of the use of robots, in the modern society, shows that they have a positive influence on human beings, but if the robots were overused, it could lead to a negative side. which shows why human beings should use robots wisely that will result an improvement to their societies and own lives. Robots have become interactive equipment whereby they have become part of human life. In this regard, people use them directly or indirectly to enhance the quality of their lives. However, Sharkey argues that there are ethical issues that arise because of using robots to enhance hu...
Robots are one of the artificial intelligence that made a breakthrough across all fields of life. In consequence, many research studies and projects regarding robots took place in the last decade. In addition, robots in the society could be one of the essential machines, due to their multitask system which could adjusted to any kind of performance. In general society could use these machines to fill manpower gap in short time with less cost. Therefore, robots can have huge positive effects on different fields of life such as emergency situations, daily chores, and manufacturing industry.
