The Key to Safer Autonomous Cars: A Humanoid Robot Behind the Wheel?
In a groundbreaking study published by researchers at the University of Tokyo, a compelling argument is made for incorporating a humanoid robot as the driver of autonomous cars. This innovative approach aims to address the ongoing challenges of pedestrian safety and avoiding collisions with obstacles such as telephone poles.
The researchers have developed and trained a “musculoskeletal humanoid” named Musashi to drive a small electric car on a test track. Musashi is equipped with two cameras that serve as its eyes, allowing it to “see” the road ahead and the views reflected in the car’s side mirrors. With its mechanical hands, Musashi can perform various driving tasks such as rotating the car’s key, pulling the handbrake, and switching on the turn signal. Additionally, its anti-slip “feet” enable it to control the accelerator and brake pedal.
By feeding Musashi raw sensor data and teaching it how to use the car’s steering wheel, the researchers successfully guided the robot in turning a corner at an intersection while respecting traffic light signals. However, there are some limitations and areas for improvement.
During the test, Musashi cautiously lifted its “foot” off the brake pedal to make the turn instead of tapping the accelerator. This cautious approach, attributed to technical limitations, resulted in the turn taking approximately two minutes. Furthermore, in a separate experiment where Musashi did use the accelerator, it struggled to maintain a consistent speed depending on the road’s incline.
Despite these limitations, the researchers remain optimistic and committed to overcoming these challenges. Their plans include developing a next-generation robot and software, with the ultimate goal of eventually having Musashi operate as a driver for Tokyo taxis.
While this research presents an exciting possibility for the future of autonomous vehicles, it is crucial to acknowledge that there is still much work to be done. The integration of humanoid robots into autonomous driving systems requires further refinement to ensure optimal safety, efficiency, and reliability. Nonetheless, the efforts of the University of Tokyo researchers provide a promising glimpse into the potential of this innovative approach.
As the development of autonomous vehicles continues to progress, it is essential to explore various solutions that prioritize safety and enhance the overall driving experience. Incorporating humanoid robots behind the wheel offers a unique perspective and may contribute significantly to the advancement of autonomous driving technology. With continued research and advancements, the day when Musashi or similar robots become a common sight on the roads may not be too far off.
