"Researchers from the James Watt School of Engineering in Glasgow are claiming to have constructed a new development in affordable, open-source mobile networks that enables near-real-time control of robotic arms. The technology could help doctors work on patients in remote locations in the years to come. The first demonstration of the medical innovation has seen the research team use the system to perform mock dental exams on a pair of dentures, highlighting its potential for use in medical procedures."
"The system is based on off-the-shelf hardware that has been used to build a 4G LTE mobile network which connects a haptic controller to a robot arm, with the network allowing users to direct the arm's movements with very low latency, enabling a high level of control. The research team built their framework using the Open Radio Access Network (O-RAN) framework, which uses open-source software to control mobile network hardware. They repurposed a USB network dongle, more commonly used for consumer mobile internet, to create stable connections between the haptic input device, the robotic arm and a computer configured to act as an intelligent base station."

The framework is based on the Open Radio Access Network (O-RAN) and repurposes a consumer USB mobile dongle to provide stable links. Signal quality, data rates and latency were tuned with specialised xApps. Lab tests achieved 10 Mbps bandwidth, under one second latency, minimal signal loss, and power consumption of 4.5 W versus 45 W for SDR approaches.
