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!).

Andy Lewis demonstrates the effectiveness of gravity compensation on Shoulder joint (joint 0) on both arms.

Gravity compensation is expected to improve controller performance.

Thanks Andy!

Raven II inverse kinematics implementation is now online! While there are still a few kinks to be worked out, the solution is now operable.

What’s left to be resolved? Glad you asked! The biggest SNAFU so far seems to be the rollover of the “tool roll” axis around 2Pi. These kind of boundary cases must be identified and resolved.

Great stuff happening at UC Berkeley!

It’s interesting to note that they’ve broken more cables (2) than any other partner site so far. This just proves Jacob’s old adage that if you’re not breaking anything you’re probably not doing much work!

Let me Google that for you
