RavenII Dev Blog

The Applied Dexterity booth at ICRA 2013 Karlsruhe was a tremendous success! The highlight of the show was a spontaneous collaboration with Force Dimension connecting the Sigma.7 haptic interface to the Raven II surgical system.

It was decided on Tuesday that we should try the Sigma.7 as a master,. Tuesday night we wrote the necessary code while sitting outside at the AlteBank Biergarten, and debugged with a little help from the Force Dimension engineers. Wednesday was a complete success and a great demonstration of both devices capabilities, and the power of open-source software!

This video demonstrates the use of Virtual Fixtures in Robotic Laser Surgery. Virtual Fixtures are used to keep the laser fiber from touching the kidney. In addition, these fixtures assist the surgeon in tracing a tumor by creating a margin around it.

This video shows the Raven II moving to a series of points. Movement is automatic, and to a pre-determined point. Each movement is triggered by a human operator pressing a keyboard key.

This is the fastest we’ve seen the Raven II move (on purpose!).
