The following video highlights the 3 most advanced humanoid robots.


3) Include a picture of your robot.



4) Develop a timeline of the historical development of robots (p. 243 to 244). Use an online timeline tool to create your time line.


950
Alan Turing publishes Computing Machinery and Intelligence in which he proposes a test to determine whether or not a machine has gained the power to think for itself (The "Turing Test"). Since then each year a contest is held between various software developers to determine how close they have come to the true Turing Machine.

1952
The first Numerically Controlled (NC) machine is built at MIT by John T. Parsons. It is connected to Whirlwind (See 1946). It was used to make ashtrays for visiting guests.

1954
George Devol and Joe Engleberger design the first programmable robot "arm". This development led to the development of the first industrial robot “UNIMATE” in 1961.

1961
The first industrial robot (UNIMATE) is installed in a General Motors automobile factory in New Jersey. The assembly line robot is controlled step-by-step by commands stored on a magnetic drum; the 4,000-pound arm sequenced and stacked hot pieces of die-cast metal.

1963
The first artificial robotic arm to be controlled by a computer is designed at Rancho Los Amigos Hospital in Downey, California as a tool for the handicapped. The Rancho Arm’s six joints gave it the flexibility of a human arm.

1965
Homogeneous transformations first applied to robot kinematics.

1969
Victor Scheinman, a Mechanical Engineering student working in the Stanford Artificial Intelligence Lab (SAIL) creates the Stanford Arm. It was the first successful electrically powered, computer-controlled robot arm. By 1974, the Stanford Arm could assemble a Ford Model-T water pump, guiding itself with optical and contact sensors.

1970
Shakey created at the Stanford Research Institute (SRI). It is the first mobile robot controlled by artificial intelligence. Equipped with sensing devices driven by a problem-solving program called STRIPS, the robot could find its way around by applying information about its environment to a route. Shakey used a TV camera, laser range finder, and bump sensors to collect data, which it then transmitted to a DEC PDP-10 and PDP-15. The computer radioed back commands to Shakey — who then moved at a speed of 2 meters per hour.

1977
Star Wars is released. George Lucas' movie introduces viewers to R2D2 and C3PO. The movie creates the strongest image of a human future with robots since the 1960's and inspires a generation of researchers.
ASEA, a European robot company, offers two sizes of electric powered industrial robots. Both robots use a microcomputer controller for programming and operation.

1980
Seymour Papert publishes Mindstorms: Children, Computers, and Powerful Ideas where he advocates constructivism, or learning through doing.

1981
Takeo Kanade builds the direct drive arm. It is the first to have motors installed directly into the joints of the arm. This development makes joints faster and much more accurate than previous robotic arms.

5) Who is Isaac Asmiov and what was he famous for?
He made the 3 laws of robotics;

The Three Laws are:
  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
  3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.






See following for more information on Mr Asmiov
i) http://www.biography.com/people/isaac-asimov-9190737
ii) http://en.wikipedia.org/wiki/Isaac_Asimov


If you have time, watch the interview with Isaac Asimov in 1988



6) Add the three laws of robotics to the following table. Then complete the remaining two columns.


3 Robotic Laws

Benefits
Disadvantages
1) A robot may not injure a human being or, through inaction, allow a human being to come to harm.


A robot cannot harm a human
robots cannot be used in war
2)
A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.

Robots cannot be killing machines
disadvantage- robots cannot be used instead of humans

Disadvantage- can sometimes confuse robot
3)A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.


Robots have morals
Robots can make bad decisions


Disadvantage to law No.2 (table did not let me input): Robots cannot be used for defence in homes (against robbers for example)

7) The EPRSE (Engineering and Physical Science Council Research Council) has developed 5 principles for robotic use and development. What are they? 
1) Robots are multi-use tools. Robots should not be designed solely or primarily to kill or harm humans, except in the interests of national security.

2) Humans, not robots, are responsible agents. Robots should be designed; operated as far as is practicable to comply with existing laws & fundamental rights & freedoms, including privacy.

3) Robots are products. They should be designed using processes which assure their safety and security.

4) Robots are manufactured artefacts. They should not be designed in a deceptive way to exploit vulnerable users; instead their machine nature should be transparent.

5) The person with legal responsibility for a robot should be attributed.



Click on the EPSRC logo below for more information.


EPSRC - Engineering and Physical Sciences Research Council

8) Why has EPRSE developed the 5 principles? 

So that humans can co-exist with robots without getting the wrong idea about what they are.




Click the EPSRC logo ago to get more information.



9) The EPRSE believe robots have the potential to provide immense positive impact to society. Do you believe this statement is true? Justify your answer.

Yes, this is true, as robots can greatly influence society by making their lives easier.
10) How fare will robotics go? Are we close to making realistic humanoid robots?....  Check out the following two videos..

We are close to making humanoid robots, but they are not smart. 


Following video is where we currently are at with Humanoid Robots



Following German video is where they are predicting we will soon be...


So... what do you think. Do you think it is possible a Robot like Eve 2.0 will be made?

11)  Probably not in the next few decades, as robots like eve would be incredibly hard to make, and the computers necessary for calculations for eve would have to be very powerful.

1) What is a Network??

A network is a communication system that allows two or more computers and their peripheral devices to be conected in order to exchange data or information within a computer system and within networks. Networks can be small or large, permanently connected through wires or cables, or temporarily connected theough phone lines or wireless transmissions. The simplest network is two computers directly connected to each other using a cable.


2) My Bubbl.us brainstorm.



3) What are protocols?
A protocol is a set of rules that controls the movement of data. There are many of these rules on a network for different purposes and situations. The hardware requires one set of rules, the software a second set of rules, and the transfer of data yet another set of rules.

4) Describe handshaking

Handshaking is the exchange of agreed rules at the beginning of any conenction between nodes. Whenever a network transfers data, the rules must first be checked. Both the sender and the receiver must use the same rules so that they can clearly understand the processes they will use to transmit.
5) Describe the following protcols

i) TCP/IP: Short for Transmission ControlProtocol/Internet Protocol, the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP
ii) HTTP: Short for HyperText Transfer Protocol, the underlying protocol used by theWorld Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.
iii) FTP: FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network. You can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, or access online software archives.
iv) SMTP: SMTP stands for Simple Mail Transfer Protocol. It's a set of communication guidelines that allow software to transmit email over the Internet.
v) IPX/SPX: Short for Internetwork Packet Exchange, a networking protocol used by theNovell NetWare operating systems. Like UDP/IP, IPX is a datagram protocol used for connectionless communications. Higher-level protocols, such as SPX and NCP, are used for additional error recovery services.
vi) Netbui: 
NetBEUI (NetBIOS Extended User Interface) is a new, extended version of NetBIOS, the program that lets computers communicate within a local area network.

vii) Appletalk:
AppleTalk is a set of local area network communication protocols originally created for Apple computers. An AppleTalk network can support up to 32 devices and data can be exchanged at a speed of 230.4 kilobits per second (Kbps). 


  6. Provide a description and a picture of the following 
i) Simplex transmission 


Alternatively referred to as simplex communication or simplex transmissionsimplex is a one-way only communication standard. Broadcast information, or data, can only travel in one direction, versus duplex which allows for two-way broadcasting.

ii) Half duplex transmission 

Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time.




iii) Full duplex transmssion



Refers to the transmission of data in two directions simultaneously. For example, a telephone is a full-duplex device because both parties can talk at once.



  7. Define the following rates of transmission (p. 212)
i) Bits per second (bps)
In data communications, bits per second (abbreviated bps or bit/sec) is a common measure of data speed for computer modems and transmission carriers.

ii) Baud rate
symbols per second or pulses per second. It is the unit of symbol rate, also known asbaud rate or modulation rate; the number of distinct symbol changes (signaling events) made to the transmission medium per second in a digitally modulated signal or a line code.

    8. Compare and contrast Parallel and Serial Tranmission types (p. 213)
Parallel is where each bit in a byte is transmitted along individual channels or wires so that multiple bits (in bytes or groups of bytes) are sent at the same time.

    9. Add a picture to represent 
i) Parallel Transmission and 
ii) Serial Transmission

    10. Provide an overview of Bandwidth (p. 214)

    11. Provide an overview of Wired Media. Include 
i) Coaxial, 
ii) Fibre Optic
iii) Twisted Pair cable in your overview (p. 215)

    12. Add a labelled picture of 
i) Coaxial Cable and 
ii) Fibre Optic and 
iii) Twisted Pair Cable

    13. Give an overview of packet switching in networks. (p. 216-217)

    14. Define the following types of networks and provide an example and picture of each. 
i) Local area network (LAN) - definition, example and picture 
ii) Wide area network (WAN) -definition, example and picture 
iii) Client-server network - definition, example and picture 
iv) Peer to Peer networks - definition, example and picture

   15. Explain what a torrent file is. How and why they are used. An example of a torrent program and what type of network (from q. 14) they are.
