I. Ｉｎｔｒｏｄｕｃｔｉｏｎ

Teleportaion = a kind of transportation.– Sends an object to a remote place.– In a short time.– Without using physical transportation

system. Examples:

– FAX– TV

Teleportation is

One of our dream. It may– Save Time, Save Money

– Send an object to Space Stations, a Deep Sea, or an Isolated place easily.

• more development of scientific and technical advance at the remote place

We want to send functional machines, such as toys, robots, vehicles, …

A teleportation

1. Extracts all Information from an object,

2. Sends the Information to a remote place,

3. Constructs the Identical Object at the remote place, • using the information and materials at that

place.

II. Outline of Our Teleportation system

1. Extracting the information

Previous methods:– 3D digitizers

(stereo camera, laser digitizer, …)• Only surface

– CT, MRI … can get the inside information but

• Difficult to get the functional information

Our approach:– The object is made of the intelligent parts.

(restriction)

– Self recognition of the whole object by intelligent parts

– Entire information of the object (its outside structure, its inside structure, its function, its state,…) can be extracted.

2. Sending the Information

We already have High speed computer networks

3. Constructing the Identical Object

We already have industrial robots now.

III. Intelligent Parts used for the teleportation system

Two kinds of prototypes of the intelligent parts

I. cubical type 　 　 II. square-pie type

Inter-connection and communication mechanism of the parts I (cubical)

Self-recognition mechanism of the object

Use a Syntactic Analysis The probe is the start symbol S. S →G(l,m). A (connectable) face is a non-terminal symbol. F(l,m) o

r G(l,m) A part is a production rule G(l,m0)→F(l,m1),…,F(l,mk)

– can be applied only one time in the parsing.

– In order to avoid the loop.

A connection of two faces (parts) is also a production rule F(l,m)→G(j,k).

Terminal symbol ε 　 means, a face is not connected to another face (F(l,m)→ε) or a production rule was already used in the parsing. (G(l,m)→ε)

An attribute grammar. S →G(l,m). S.s=G(l,m).s

A Synthesized attribute of S which represents the object’s information

S.s=G(0,1).s G(0,1).s=(“part information” 0 nil F(0,2).s nil nil nil

(information-of-this-part-except-this-list))– Part 0’s = F(0,2).s + its information.

F(0,2).s=(“connection information” 0 2 1 4 0 G(1,4).s)– Part 0-face 2 is connected with part 1-face 4, 0, …

G(1,4).s=(“part information” 1 nil nil nil F(1,3).s nil (information-of-this-part-except-this-list))

F(1,3).s=(“connection information” 1 3 2 1 0 G(2,1).s) …

IV. Computer Simulation

V. Application to a 3D Modeling and a Self Reproduction

A 3D modeling, a strain analyzer of 3D structure (if each part has strain gauges), 3D input devices, …

A self reproduction – If the transmitter and the receiver

are connected, and they are also made of the intelligent parts?

VII. Concluding Remarks A method for realizing a practical

teleportation sending a practical object to a remote place The object can be an automatic machine

such like a robot 3D modeling and self reproduction Weak points

– The object must be made of the intelligent parts.

– The parts must be prepared at the remote place.

We are realizing it now!
