 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-- **Autonomous Vehicles & Drones** – Self-driving cars and UAVs (unmanned aerial vehicles) became more advanced.
-- **Medical Robotics** – Robots like **da Vinci Surgical System** revolutionized healthcare.
-- **Personal Robots** – Devices like **Roomba** (vacuum robot) and **Sophia** (AI humanoid) became popular.
-- **Collaborative Robots (Cobots)** – Robots started working alongside humans in industries.
+- **Autonomous Vehicles** – Self-driving cars for robo taxi like `Waymo`_ and autonomous haulage system in mining like `AHS`_ became more advanced and bisiness-ready.
