NEW Journal Article: Improving Rigid 3-D Calibration for Robotic Surgery

Autonomy is the next frontier of research in robotic surgery and its aim is to improve the quality of surgical procedures in the next future.

One fundamental requirement for autonomy is advanced perception capability through vision sensors.

In this article, we propose a novel calibration technique for a surgical scenario with a da Vinci® Research Kit (dVRK) robot. Camera and robotic arms calibration are necessary to precise position and emulate expert surgeons. The novel calibration technique is tailored for RGB-D cameras.

MULTIROBOTS-SURGERY platform conceptual ROS* architecture

The MULTIROBOTS-SURGERY platform is designed as a collection of functional modules, each one devoted to a single task.

We implemented the MULTIROBOTS-SURGERY platform as a collection of ROS* nodes. All the ROS nodes are connected to a central unit acting as ROS core, in charge of providing a common timestamp and driving the communication between nodes, and data recording module.

The figure shows the conceptual architecture of MULTIROBOTS-SURGERY platform in terms of ROS nodes.

*ROS is an open source, distributed, component-based development framework that has become the standard de facto for interfacing heterogeneous hardware and software in robotics applications.

The problem of real-time motion planning

The robot motion planning is generally solved before the robot actually executes the desired motions and in case of motions that must avoid obstacles, this approach may work with static obstacles only. 

If, instead, obstacles are moving, the desired motion must be calculated in real-time, a few milliseconds before its execution.

 The setup used for the experiments. SARAS, Smart Autonomous Robotic Assistant Surgeon.
