tion mechanism, the cane will then convey the appropriate travel direction to the user. In addition to increasing mobility for the visually impaired and thus quality of life, methods developed in the creation of this technology could lead to general improvements in the autonomy of small robots and portable robotics that have many applications in military surveillance, law enforcement, and search and rescue efforts.

MRI-Guided Co-Robotic Active Catheter: Atrial fibrillation is an irregular heartbeat that can increase the risk of stroke and heart disease. By purposefully ablating (destroying) specific areas of the heart in a controlled fashion, the propagation of irregular heart activity can be prevented. This is generally achieved by threading a catheter with an electrode at its tip through a vein in the groin until it reaches the patient's heart. However, the constant movement of the heart as well as unpredictable changes in blood flow can make it difficult to maintain consistent contact with the heart during the ablation procedure, occasionally resulting in too large or too small of a lesion. The aim is to develop a co-robotic catheter that uses novel robotic planning strategies to compensate for physiological movements of the heart and blood and that can be used while a patient undergoes MRIan imaging method used to take pictures of soft tissues in the body such as the heart. By combining state-of-the art robotics with high-resolution, real-time imaging, the co-robotic catheter could significantly increase the accuracy and repeatability of atrial fibrillation ablation procedures.
