Mechanism for Efficient Stiffness Modulation of Springs

Summary Vanderbilt researchers have developed a novel variable stiffness spring mechanism that affords low energy cost stiffness adaptation. Essentially, the energy cost of changing the stiffness of the spring is rendered independent of the energy stored in the spring. Addressed Need Compared to constant stiffness springs, variable stiffness springs...

Inexpensive Disposable Hydro-Jet Capsule Robot for Gastric Cancer Screening in Low-Income Countries

Summary Gastric cancer is the second leading cause of cancer death worldwide. While screening programs have had a tremendous impact on reducing mortality, the majority of cases occur in low and middle-income countries (LMIC). Typically, screening for gastric and esophageal cancer is performed using a flexible endoscope; however, endoscopy resources...

Endonasal Surgical Robot for Sinus and Neurosurgery

Summary Vanderbilt engineers have developed a robotic system for performing sinus and neurosurgery through the nose. This provides a less invasive way to access surgical sites in the sinuses and near the middle of the patient's head, leading to faster recovery times. The robot is modular and sterilizable with detachable cartridge-based instruments....
