March 15, 2014 | Partnerships and publications in flexible robotics

201411 09CEA LIST’s flexible robotics programs have been making news of late. First, a partnership has been signed with Géoservices to automate the company’s processes for grinding, testing, and handling rock samples from petroleum extraction. Another partnership has been set up with Warein, a SME based in Brittany. CEA LIST will help Warein develop a robotic arm made from a textile and inflated with compressed air. The arm, which would offer a range of over 10 meters, could be used to carry out inspections inside very small spaces without damaging their interior surfaces.

CEA LIST’s flexible robotics research appeared in two publications: the 400-page Flexible Robotics: Applications to Multiscale Manipulations (French title: Robotique flexible : manipulation multi-échelles) and an article in The international journal of robotics research that explored an anthromorphically-inspired, multi-finger lightweight robotic hand co-developed by CEA LIST under several joint research initiatives.

The institute’s flexible robotics research also covers micromanipulators leveraging active materials and highly functionally integrated effector systems.

March 4, 2014 | 3D imaging guides orthopedic surgery

Researchers from CEA LIST are helping make life easier for surgeons specializing in corrective osteotomy of the radius. The research, which is part of the EU ITEA Mediate project, is looking at how new 3D imaging methods can help surgeons compare a picture of the actual realignment of two sections of the radius with an image of an « ideal » realignment created prior to the surgery.

CEA LIST developed an algorithm to correct imaging errors generated by the metal pins implanted in the patient. The researchers used an image processing technique called inpainting to minimize the errors’ impact on the 3D image of the actual alignment of the sections of the radius. The institute also implemented iterative algorithms that reduced the number of images needed to reconstruct the 3D image, keeping radiation doses lower for both patients and operating room staff.

The method was developed in conjunction with the Academic Medical Center of Amsterdam and was validated on a human specimen at Digiteo Labs in Saclay. CEA LIST researchers are continuing their work with the Dutch team to produce the 3D bone model from just a few projections.
