Robot masseuse gets hands-on in Singapore trial

Known as EMMA (Expert Manipulative Massage Automation), the technology was developed by AiTreat, a start-up company spun out of Nanyang Technological University Singapore (NTU Singapore). It uses a fully articulated robotic limb that operates through six degrees of freedom, with two silicon massage tips mounted at the end. Sensors measure the stiffness of tendons and muscles, while a cloud-based artificial intelligence (AI) computes the exact pressure required for each patient. The AI can also analyse the progress of the patient, generating a performance report that tracks recovery.

This is the third incarnation of the robot and the first to go into public service. According to AiTreat, EMMA could help reduce healthcare costs, fill gaps where there are staff shortages, and deliver care to ageing populations around the world. The current trial will see EMMA placed between two treatment beds, performing repetitive massage on one side while the therapist attends a second patient on the other. This set up was configured to maximise EMMA’s productivity while allowing the therapist to deliver more focused care.
