A 'Hands Off' Physical Therapy Assistance Robot
Adviser: Prof. Maja J. Matarić
Developed a system to empirically study the effects of different types of interaction between
robotic assistants and cardiac surgery patients. The system assists patients in reaching their
physical therapy goals by providing engaging feedback and encouragement during the completion
of painful but necessary breathing exercises. Patients of cardiothoracic surgery are required to use
special breathing equipment every hour in order to prevent pneumonia and speed recovery. Nurses
are too busy to oversee all the sessions throughout the patient’s stay, and patients quickly lose
their internal motivation to complete the exercises because of physical discomfort or boredom.
The robot employs a ‘Hands-Off’ approach to providing assistance, allowing for lower cost designs
and decreased liability. A proof of concept experiment was conducted at the USC University
Hospital and experiments were conducted to evaluate the relative effectiveness of purely verbal
communication and interaction that incorporated the use of a small PDA type device. The system
provided a popular demonstration for the Interaction Laboratory.
