Telesurgery is an interdisciplinary field of teleoperated robotics and robot-assisted minimally invasive surgery, and has good promising future. In this work, the structure and work flow of the tele-neurosurgery are addressed at first. Then the key technologies involved, including our newly developed surgical robot, untouched methodology in localizing marks(More)
Image distortion correction and geometric calibration are critical operations for using C-arm DSA (Digital Subtraction Angiography) images to digitally navigate vascular interventional surgery. In traditional ways, C-arm images are corrected with global or local correction methods where a supposed virtual ideal image is needed, and then the corrected images(More)
In this paper, we present the design of a social robot, Nancy, which is developed as a platform for engaging social interaction. Targeting for a social, safe, interactive and user-friendly robot mate, the design philosophy of Nancy is presented with mechanical, electrical, artificial skin and software specifications. In particular, there are 32 degrees of(More)
Drivable area detection is an important issue for mobile robot to work in indoor and outdoor environments with safety and security with respect to itself and environment. In this paper, we propose an approach to detect the ground area for indoor mobile robots with binocular cameras. At first, the ground induced homography between onboard binocular cameras(More)
BACKGROUND Robot-assisted vascular interventional surgery (VIS) enables the surgeon to teleoperate a catheter in a safe cabinet, such that exposure to X-ray radiation is reduced. For safe and accurate teleoperation, system structure and image guidance is important. METHODS The system structure of the developed remote-controlled vascular interventional(More)
A shortest path-based algorithm is proposed in this paper to find splitting lines for touching cell nuclei. First, an initial splitting line is obtained through the distance transform of a marker image and the watershed algorithm. The initial splitting line is then separated into different line segments as necessary, and the endpoint positions of these line(More)
This paper presents a novel design for the soft continuum manipulator based on beehive structure. Our design inspiration derives from the beehive hexagon structure, which has some characteristics of compact layout, low material consumption, thinner thickness of wall, and higher structure strength. The manipulator includes several same modules which composed(More)
