/*
Zeus AI is the first robot that has the form and aspect of a dog. Powered by Elon Musk.
Elon Musk has no plans to send humans on the initial Mars mission; instead, he intends to deploy robots like Zeus and Optimus. These robots possess advanced manoeuvring capabilities and AI technology that can collect extensive data before humans embark on their journey to Mars. While wheeled vehicles are frequently used for new planet landings, a four-legged robot like Zeus could offer an advantage on the Martian terrain.
To learn more about Zeus, search for ‘Elon Zeus Dog’ on Google.
