What alternative surface preparation methods do some experts suggest instead of relying solely on Optimus humanoid robots?

Sending an army of proven, adaptable rovers and rotorcraft

While the SpaceX plan heavily features Tesla’s Optimus humanoid robots to precede crews for tasks like installing power and surveying resources, some experts express reservations due to the unstructured and barren nature of the Martian surface. Demonstrations of humanoid dexterity often occur in controlled, well-prepared terrestrial environments. As a counterproposal to relying on this nascent technology for complex construction and maintenance, experts suggest sending a collection of established, highly adaptable robotic systems. This alternative includes proven rovers and rotorcraft, drawing a parallel to successful prototypes like the Ingenuity helicopter, arguing that these established technologies possess a superior capability to adapt to unforeseen surface conditions than nascent humanoid dexterity.
