Just days after Sarah Palin’s selection last August as the Republican vice presidential candidate, a photo of a bikini-clad, gun-toting Palin blitzed across the Internet. Almost as quickly, it was revealed as a hoax—a crude bit of Photoshop manipulation created by splicing an image of the Alaska governor’s head onto someone else’s body. From start to finish, the doctoring probably took no more than 15 minutes.

IHMC’s Nadia is a Versatile Humanoid Teammate

This robust research platform is still humble enough to teleoperate

The Florida Institute for Human & Machine Cognition (IHMC) is well known in bipedal robotics circles for teaching very complex humanoid robots to walk. Since 2015, IHMC has been home to a Boston Dynamics Atlas (the DRC version) as well as a NASA Valkyrie, and significant progress has been made on advancing these platforms toward reliable mobility and manipulation. But fundamentally, we’re talking about some very old hardware here. And there just aren’t a lot of good replacement options (available to researchers, anyway) when it comes to humanoids with human-comparable strength, speed, and flexibility.

Several years ago, IHMC decided that it was high time to build their own robot from scratch, and in 2019, we saw some very cool plastic concepts of Nadia—a humanoid designed from the ground up to perform useful tasks at human speed in human environments. After 16 (!) experimental plastic versions, Nadia is now a real robot, and it already looks pretty impressive.

These IEEE members connected with each other at this year's IEEE International Conference on Robotics and Automation, held in London.

The word home evokes a sense of belonging and welcoming. IEEE aims to create a similar feeling by offering services for members at every stage of their career and by building a community among them.

IEEE President and CEO K.J. Ray Liu is committed to making IEEE the professional home for members. As he announced in his March column in The Institute, he’s doing that by “examining ways in which the organization could evolve to best meet the needs of all technical professionals in the years ahead.”

WIPL-D

Handling various complex simulation scenarios with a single simulation method is a rather challenging task for any software suite. We will show you how our software, based on Method-of-Moments, can analyze several scenarios including complicated and electrically large models (for instance, antenna placement and RCS) using desktop workstations.
