Docomo, Keio University claim 5G robot teleoperation first | Computer Weekly

"RealHaptics is an advanced force feedback system that transmits, records and reproduces the tactile sensation of touch in real time, allowing remote operators to feel the resistance, softness or texture of objects handled by a robotic device."

"To convey precise force feedback when a remote robot interacts with objects controlled by an operator at a distant location, mobile data communication must maintain low latency and minimal jitter. High or fluctuating latency can disrupt synchronisation between the operator and remote robot."

"The demo has seen the combination of Configured Grant, a network slicing scheduling method in which the base station pre-allocates communication resources to specific devices - with Keio's Real Haptics technology, invented by Kohei Onishi, transmitting tactile and contact information bidirectionally and reproducing human force on robots."

Physical artificial intelligence represents a major growth area in industrial automation. NTT Docomo and Keio University's Haptics Research Centre successfully demonstrated remote robot operation over commercial 5G networks using RealHaptics technology. RealHaptics is an advanced force feedback system that transmits, records, and reproduces tactile sensations in real time, allowing remote operators to feel resistance, softness, and texture of objects handled by robotic devices. The demonstration combined Configured Grant, a network slicing scheduling method that pre-allocates communication resources, with RealHaptics technology to transmit tactile and contact information bidirectionally. Precise force feedback requires low latency and minimal jitter in mobile communication to maintain synchronization between operator and robot, ensuring delicate operations remain accurate.
