Collaborative Robot as Scrub Nurse

Scrub Nurse Robot for Laparoscopic Surgery

During laparoscopic surgeries, changing forceps is a relatively simple procedure that requires a nurse or another surgeon; however, most hospitals lack a scrub nurse in the operating room. Therefore, we have developed an assisting robot for laparoscopic surgery that is able to pass or receive forceps under the voice control of the surgeon. This robot system consists of a magazine that holds all...

Robot Facilitation as Dynamic Support for Collaborative Learning

Automated as well as remotely controlled robots have high potential to expand our research and practice in collaborative learning environments. The area of computer supported collaborative learning (CSCL) is one in which advanced technologies have been used effectively to automatically monitor and dynamically structure group discussions for learning. Traditional desktop environments for collabo...

Robot as Partner: Vehicle Teleoperation with Collaborative Control

We have developed a new teleoperation system model called collaborative control. With this model, the robot asks the human questions, to obtain assistance with cognition and perception during task execution. This enables the human to support the robot and to compensate for inadequacies in autonomy. In the following, we review the system models conventionally used in teleoperation, describe coll...

Collaborative Multi-Robot Exploration

In this paper we consider the problem of exploring an unknown environment by a team of robots. As in single-robot exploration the goal is to minimize the overall exploration time. The key problem to be solved therefore is to choose appropriate target points for the individual robots so that they simultaneously explore different regions of their environment. We present a probabilistic approach f...
