PhoneBot: Humanoid Robot Using Old Smartphones

Researchers at the University of California, Los Angeles (UCLA) have developed an innovative humanoid robot called PhoneBot, which integrates low-cost Android smartphones for vision and control tasks. This project marks a significant advancement in robotics, allowing enthusiasts and creators to access a robotic system for approximately $400, excluding the cost of the phone.

PhoneBot stands 483 mm tall and weighs 1.8 kg, utilizing 13 servo motors to control its movement. The fascinating aspect of this design is that it eliminates the need for dedicated cameras and sensors, as the smartphones handle vision, processing, and robot control. This not only reduces costs but also simplifies the building process.

## Why it matters The creation of PhoneBot highlights the growing trend of reusing technological devices in robotics, promoting sustainability and innovation. Additionally, its economic accessibility may encourage more individuals to engage in robotics, democratizing access to this advanced technology.

## What we know Researchers have stated that PhoneBot is an open-source platform, meaning that other developers can contribute and enhance its design. This collaborative approach could lead to new applications and improvements in the field of robotics.

## What remains unclear It has yet to be detailed how PhoneBot performs in complex situations or real-world environments. Moreover, it is unknown if there will be future updates or enhancements to the hardware that expand its capabilities.
