Could controlling a robotic arm be as simple as using your smartphone? Researchers at Georgia Tech believe the answer is yes.
Georgia Institute of Technology researchers have developed COBALT, a new platform that allows users to operate robotic arms remotely through a smartphone and an internet connection. The system removes many of the technical barriers that typically make robotics difficult for beginners.
Designed with accessibility in mind, COBALT enables people with little or no robotics experience to interact with and control robotic systems from virtually anywhere. This could open the door to wider adoption of robotics in education, research, and everyday applications.
By combining user-friendly mobile controls with cloud-based connectivity, COBALT demonstrates how advanced robotics can become more accessible to the general public. The innovation represents a significant step toward making robotic technology easier, more practical, and available to everyone.
Turning Smartphones Into Robot Remotes
Developed at Georgia Tech’s PAIR Lab, COBALT transforms a smartphone into a real-time motion controller for robotic arms. By simply moving their phones, users can make the robot mimic their actions instantly, while basic tasks like grabbing, moving, and releasing objects are handled through easy on-screen controls.
Built for simplicity, COBALT requires no robotics expertise. In testing, participants from India, Indonesia, and Pakistan successfully operated robotic arms at Georgia Tech using only their smartphones and an internet connection, despite having no prior experience with robotics.
Turning Users Into AI Trainers
COBALT isn’t just making robots easier to control—it’s also helping solve one of robotics’ biggest challenges: collecting high-quality training data for AI.
Modern robots need massive amounts of real-world data to learn tasks effectively, but gathering that data is often slow, expensive, and limited to specialized labs.
Researchers believe a global network of smartphone users could change that. By remotely operating robots through COBALT, everyday users can generate valuable training data that helps AI-powered robots learn faster and perform better.
Robotics From Anywhere
COBALT could make robotics education far more accessible by allowing students to control real robot arms remotely using nothing more than a smartphone.
Georgia Tech recently demonstrated the system to high school students, giving them hands-on robotics experience without requiring expensive or specialized equipment. This approach could help bring robotics training to schools with limited resources.
Looking ahead, the technology could enable people to assist robots from anywhere. Whether in factories, warehouses, or homes, robots could handle routine tasks independently and call on human operators whenever they encounter situations they can’t solve on their own.
Precision Meets Familiarity
The team found that users preferred smartphones over VR headsets, keyboards, and traditional controllers. Phones felt more intuitive and familiar while still delivering precise, high-quality control data.
This approach combines ease of use with strong performance, making robot operation more accessible without sacrificing accuracy.
The system leverages WebRTC—the technology behind many video-calling platforms—to minimize latency and enable fast, responsive robot movements.
By combining familiar smartphone interfaces with precise control, remote robotics becomes more accessible, intuitive, and reliable.
As a result, robotic arms can be operated from virtually anywhere with a natural and seamless user experience.
