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.
