ONLINE COVER Hands-Free. The promise of going "hands-free" and allowing a robot to do all the work has eluded soft-tissue surgeries, such as in cardiovascular or gastrointestinal procedures, because the tissue is deformable. In this issue, Shademan and colleagues describe the design and operation of a robot that only requires surgeon supervision for soft-tissue surgery. The "smart tissue autonomous robot", or STAR, comes equipped with sophisticated imaging and surgical tools that together help the 'bot navigate the tissue and adapt to any movement. STAR was tested against other surgical techniques by expert surgeons for intestinal anastomoses in pigs. [CREDIT: SHEIKH ZAYED INSTITUTE, CHILDREN'S NATIONAL MEDICAL CENTER]
