Realizing a Practical Teleportation System

  1. 1. Realizing a Practical Teleportation System Using the Intelligent PartsTakashi Yamanoue+, Member, IEEE, Yasuhiro Tsutsui*, Takao Tsutsui*+ Kyushu Institute of Technology* University of Occupational Environment andHealth, Japan

  3. 3. I. IntroductionTeleportaion = a kind of transportation. – Sends an object to a remote place. – In a short time. – Without using physical transportation system.Examples:– FAX– TV
  4. 4. Teleportation isOne 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 placeWe want to send functional machines, suchas toys, robots, vehicles, …
  5. 5. II. Outline of Our Teleportation systemA teleportation1. 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.
  6. 6. 1. Extracting the informationPrevious methods:– 3D digitizers (stereo camera, laser digitizer, …) • Only surface– CT, MRI … can get the inside information but • Difficult to get the functional information
  7. 7. 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.
  8. 8. 2. Sending the Information We already have High speed computer networks3. Constructing the Identical Object We already have industrial robots now.

  10. 10. III. Intelligent Parts used for the teleportation systemTwo kinds of prototypes of the intelligent partsI. cubical type     II. square-pie type
  11. 11. Inter-connection and communicationmechanism of the parts I (cubical) Photo sensor Lighting device Magnet S Magnet N
  12. 12. Inter-connection and communicationmechanism of the parts II (square pie) Magnet Magnet S N Photo sensor Lighting device
  13. 13. Self-recognition mechanism of theobjectUse a Syntactic AnalysisThe probe is the start symbol S. S →G(l,m).A (connectable) face is a non-terminal symbol. F(l,m)or 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 productionrule F(l,m)→G(j,k).Terminal symbol ε   means, a face is not connected toanother face (F(l,m)→ε) or a production rule wasalready used in the parsing. (G(l,m)→ε)An attribute grammar. S →G(l,m). S.s=G(l,m).s

  17. 17. V. Application to a 3D Modeling and a SelfReproductionA 3D modeling, a strain analyzerof 3D structure (if each part hasstrain gauges), 3D input devices,…A self reproduction– If the transmitter and the receiver are connected, and they are also made of the intelligent parts?

  20. 20. 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!
