Earth Core Robot Design Specifications

This document is not professional at all unlike the other one... ignore. I took more time on that one and this is just a rough draft
  • Materials
    • Would need to withstand 5,500° C
      • How would this work? Potentially tungsten or tantalum carbide?
        • It will use Tantalum Hafnium Carbide Alloy. The melting point of it at 1 atmosphere is 3990℃, while the melting point of iron (what the core is made up of) is 1538°C. The immense pressure would raise the melting point of each material when under 3 million atmospheres. The iron at the center of the Earth is suspected to have a melting point of 6230 ± 500 Kelvin.
    • Would need to withhold 3 Million atmospheres of pressure
      • Diamond-anvil-cell-like design??
        • Yes
    • Radiation shielding
      • The core most likely has radiation. Potential shielding with lead, tungsten or combination of materials?
        • It will use Lead.
  • Propulsion
    • Laser?
      • Traditional drilling methods wouldn’t work, potentially using high-powered lasers or microwaves to melt rock??
        • It will use an extremely high powered laser, powered by the nuclear reactor
  • Power source
    • Nuclear Fission
      • A powerful nuclear reactor would provide sustainable energy that is required
  • Additional features:
    • Self-repair mechanisms
      • High temperature metallic microwelding
        • It could have a special 3d printer which uses metal filaments infused with high-temperature nanoparticles, which would be triggered by sensors.
      • Modular design
        • Basically like the Framework Laptop - if something goes wrong, there are spare parts. If a component fails, the robot could detach it, retrieve a spare, and swap them.
