3. Bio-Mechanical Arm • In the movie • Will Smith’s character has • Includes ribs • Strong enough to crush a robot • Light enough to be used by a human

4. Bio-Mechanical Arm • Properties • Strong • Light • High electrical resistivity • Low coefficient of thermal expansion • Low thermal conductivity • Melting Point

5. Bio-Mechanical Arm • Current Tech • Potential Materials • Titanium • Tungsten • Aluminum

6. Bio-Mechanical Arm-Titanium • Average melting point (1941 K) • High strength per density(4.506g/cm3vs bone density:1.6-1.9 g/cm3) • Relatively high electrical resistivity (0.420 µΩ·m vs copper: 16.78 nΩ·m) • Relatively low coefficient of thermal expansion (8.6 µm·m−1·K−1vs copper: 16.5 µm·m−1·K−1) • Relatively low thermal conductivity (21.9 W·m−1·K−1 vscopper:401 W·m−1·K−1) • Paramagnetic Cons Pros

7. Bio-Mechanical Arm-Tungsten • Very Strong • Relatively high electrical resistivity (52.8 n Ω·m vs copper: 16.78 nΩ·m) • Extremely low coefficient of thermal expansion (4.5  µm·m−1·K−1 vs copper 16.5 µm·m−1·K−1) • High melting point (3695 K) • Dense(19.25  g·cm−3) Pros Cons

8.

11. Spray Skin Current Tech • Polyisoprene (rubber) • Soluble in THF (Tetrahydrofuran) • Polyisobutylene • Soluble in THF (Tetrahydrofuran) • Aerosol

12. Movie Clip

13. Sonny • In the Movie • Super dense material • Not brittle • Opaque white • Mass production • Reproducible color

14. Sonny • Current Tech • Ceramics? • Metals? • Tungsten carbide (carbide) • Tungsten(VI) fluoride

15. Sonny Ceramics • Pros: • Electric conductivity • Thermal conductivity • Density • Cons: • Brittle

16. Sonny • Pros: • Density: 15.8 g·cm−3 • Melting Point: 2870 °C • Cons: • Color Tungsten carbide (carbide)

17. Sonny • Pros: • Density: 13.1 g/L • Stability • Cons: • Gas • Corrosive Tungsten(VI) fluoride

19. Plasma Shield • In the movie • Guards the nanobots • Destroys all that enters • Can be countered with a dense material

20. Plasma Shield • Plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist. • Plasma makes up 99% of visible universe. • Often considered the 4th state of matter. Current Tech

21. Plasma Shield • Many interesting properties: • Gas usually has a low conductivity but plasma has a very high conductivity. • Velocity of particles is not consistent. • All around us: • Lightning approaches 28,000K and electron densities may exceed 1024/m³. • Waste treatment. • Welding. • High intensity discharge lamps.

22. Plasma Shield • Two kinds high and low temperature. • Used to produce highest man made temperature. • Z Machine at Sandia National Laboratory • Plasma produced reached a temperature of 2 billion K or 3.6 billion F, peaked at 3.7 billion K or 6.6 billion °F. • Many uses including nuclear weapons research and possible energy sources.

23. Movie Clip

24. Nanobots • In the Movie • Described in movie as “microscopic robots designed to wipe out artificial synapses...a safeguard should a positronic brain malfunction”. • Inserted as injection • Viewed as a liquid – flowed into “brain” • Immediately tampered with system

25. Nanobots • Current Tech • Nanotechnology – building and influencing materials at atomic size • Nanobots - small machines that can be programmed to do any task • Nanomachines are starting to make headway, but true idea of “nanobots” still just science fiction • Still, developments are on-going • Example article

26. Dr. Painter on Nanobots • Hard to have function in something so small • Possible if was like virus, carrying info to override computer’s brain • Smallest known virus – 80 nm • If could get nanobot to function at size, could carry info like computer code • Similar to virus in computer, “hacking” into computer’s HD • Mimic the pathways of cells (for VIKI brain – electronic)

27. Plausibility • Sonny’s arm • Yes • Plasma Shield • No • Nanobots • Yes • Bio-Mechanical Arm • Yes • Spray skin • No
