Soft Exoskeleton for Human Augmentation and Restoration
We are developing both enabling technologies (i.e. high torque density motors and soft fabric sensors) and robotic systems to augment human capability with wearable robots. Soft exoskeleton is a new design methodology that optimizes both comfort and performance of the users. We believe that our lightweight and compliant exoskeleton will be new intervention and rehabilitation solutions for both neurological and musculoskeletal disorders, e.g. osteoarthritis and children with cerebral palsy.
MRI-guided Robot for Neurosurgery and Prostate Biopsy
In collaboration with Harvard Medical School, we have developed three generations of MRI-guided prostate intervention robots in collaboration with Johns Hopkins and Brigham and Women's Hospital. The robotic system, designed to improve prostate cancer biopsies, is being tested as part of a larger clinical trial at BWH. The first generation is a cylidrical needle placement robot, the 2nd generation utilized a concentric tube mechanism to actively steer needles, and the third generation deploys a parallel mechanism for angulated needle placement. Prostate cancer is the last form of cancer still diagnosed with blind needle biopsies, so we are working to change that with image-guided technology.
High Performance Electric Motor
High torque density actuator enables a new robot design paradigm - quasi-direct drive, that significantly improves the bandwidth and transparency of co-robots that interact with human or the enviroment. We developed a novel knee exoskeleton combining the advantages of a high torque density motor and a bi-directional cable transmission system. The exoskeleton is lightweight and highly backdrivable. Performance evalutation demonstrates that the torque control bandwidth is up to 30Hz. These characteristics enables safe interaction between users and the exoskeleton.
Fabry-Perot Interferometer Fiber Optic Force Sensor
Traditional sensors in robotics include force and positioning sensing. However, off-the-shelf sensors are not suiatable for use in MRI due to the potential for image degradation, malfunction, or safety issues. We are evaluating and developing sensors to be used in the MR environment. The current focus is on optical techniques for force and position sensing that do not compromise image quality and will allow for haptic feedback during MRI-guided interventions.
