OLGA(Optimized Lower-limb Gait Analysis) Explained

This article can be downloaded from Vicon hompage. It introduces the basic concepts of OLGA, the method which estimates the joint locations and relative marker locations. In also contains little descriptions on kinematic fitting of vicon software. See more details in attatched file. Introduction: OLGA (Optimized Lower-limb Gait Analysis) was introduced in 2003 as a plug-in which works with the…

Underactuated Humanoid Robot Hands

I found this article from IEEE Spectrum. This hand named as Azzurra uses special kind of underactuated mechanism(only 5 motors can actuate total 11 Dof) and which is known as Hirose’s mechanism. By using that kind of mechanism, the key feature of Azzurra is a self-contained structure. That is, all functional components including motors, sensors and controller are integrated in…

Disney Robots

Do you know robots from Disney? Beyond the animation technologies, entertainment robots are continually developed by Disney for the show and amusements in theme parks in the tradition of animatronics. For one example, Lucky the Dinosaur walks around the theme park with its usher carefully, and makes apposite gestures that it seems to be surprise, sad, angry, curious, and laugh.…

How to calculate joint kinematics using motion capture data?

The presentation shows the way to calculate joint kinematics using motion capture data. There are two methods to get the joint kinematics using different software; Vicon Nexus with Plug-in-Gait Model and OpenSim. The slides explain the detail calculation for Plug-in-Gait Model and OpenSim processing. This presentation is made by Sumin Park.

Driving Sideways

There was a really interesting article on autonomous vehicle. The article was presented in opinion page of The New york Times. The driverless car, like other utopian pursuits, seems always to be just out of reach. It’s captured the imagination of many for at least a century: in 1918, the Oakland Tribune reported (in a section I wish all newspapers…

HyQ quadruped robot makes its first public appearance in London, steps up with new feature (video)

This article makes a really interesting point, unless you work in a robotics lab, the chances are you have not seen a robot in person.  I think the idea of showcasing robots for the public is a great idea, and should be done more.  I think there are many misunderstandings about robots, and seeing it in real life is very…

Style Translation for Human Motion

Style translation is the process of transforming an input motion into a new style while preserving its original content. This problem is motivated by the needs of interactive applications, which require rapid processing of captured performances. Our solution learns to translate by analyzing differences between performances of the same content in input and output styles. It relies on a novel…
