The Evolution of Autonomous Vehicles

What Are Autonomous Vehicles?

Autonomous vehicles are automobiles capable of navigating and operating without human intervention, using a combination of sensors, cameras, AI, and connectivity. They range from partially automated systems, requiring some human oversight, to fully autonomous vehicles that operate independently. The Society of Automotive Engineers (SAE) defines six levels of autonomy, from Level 0 (no automation) to Level 5 (full automation).

The History of Autonomous Vehicles

The concept of self-driving vehicles dates back to the 1920s with radio-controlled cars, but serious development began in the 1980s. Carnegie Mellon University’s Navlab (1984) pioneered early autonomous driving research. The 2000s saw DARPA’s Grand Challenges, which spurred innovation in AV technology. Companies like Tesla, Waymo, and Cruise advanced the field in the 2010s, with Waymo launching a commercial robotaxi service in 2018.
