Galaxies on Instagram: "Elon Musk shared a video on X on October 4, 2025, showing Tesla’s Optimus humanoid robot performing punches, kicks, and defensive poses in synchronization with a human trainer in a lab setting. The robot operates through end-to-end Al neural networks processing video inputs, maintaining balance without remote control. Tesla aims to deploy Optimus in factories by late 2025 and sell up to one million units annually starting in 2026 at $20,000 to $30,000 each."
