ICT-Study Case

In South Africa occur engine-manufacturing company, has started

manufacturing complete cars. They are looking to sell cars throughout Africa.

The factory is in East London and the main office In Johannesburg, where the

manager, Simpson organizes the day to day running off the business. The main

office employs a lot of workers to produce the company payroll for all the

workers in East London and for those in Johannesburg. There is also a human

resources department in the main office in Johannesburg, which keeps all the

files on each worker. Simpson has asked CP firm and advertising company to

publish the business on a large scale. The publish company employs four

people including the manager, his name is Mazola. They need to have regular

meeting to discuss their progress with various jobs. This is difficult as they are

very rarely in the office together as they all do a lot of their works at home.

Case A:

The company uses robotic arms, to control a number of processes. Give two

reasons why they use these robotic arms? (2 points)

1. Robotic arms are able to work more accurately than human does. This

will help the company to produce high-quality products.

2. They increase productivity within a short cycle time.

Case B:

Describe how robotic arms are used into of these processes! You will need to

make 2 points for each process. (4 points)

In car manufacture company, robotic arms are used to complete many

processes of the manufacturing. Using different end effectors, a list of jobs

can be carried out by the robotic arms. The types of effectors used are:

welding guns, grippers, drills, screwdrivers/spanners, spray guns, polishers

and etc. Computer controls the robotic arms, but if the end of the effectors is

changed then the programming system also has to be changed.

Case C:

Describe how the movements of the robotic arms were originally

programmed into the computer. (5 points)

Like the arm of a human worker, a robotic arm incorporates an articulation

system or skeleton, and a set of muscles, which together function in much

the same way as their biological counterparts. The skeleton is composed of

rigid links that connect varying numbers of joints that are able to slide, twist

or rotate. The robot's muscles come in the form of actuators that convert

hydraulic, electrical or pneumatic energy into power for each joint. Next

there is an electronic nervous system of wires and sensors that carries

commands to the muscles of the robotic arm and then back to an external

computer. So originally, it works the same way as the human body system.

Another case A:

Mazola decides he needs to get in touch with his fellow executive. This has to

be done as soon as possible. Describe at least two methods by which they

could exchange ideas without having to travel into work! (4 points) (Include

in your answer additional they would need to add to their home, computers

and printers)

He could use the teleworking and telecommuting. Tele itself means at a

distance, so teleworking means working at a distance. Teleworking doesn’t

have to be done at home, as long as the person bring along a

computer/laptop with him/her. Fax machines are also needed to share the

papers that are used for their work.

Another Case B:

Mazola has considered a number of ways in which ICT could be used to

advertise the company but has decided on a web page. Discuss the reason

for his choice when compared with the other ICT alternative. (6 points)

The World Wide Web is used all around the world. Nowadays, the Internet

also provides facilities for people to use. The web page are designed to let

the user access the page easily and instantly. There are also web applications

that would ease the user to create some kinds of advertisement or

promotion. This will also help the company to sell/advertise its product

worldwide with the cheaper cost.
