Warrior Web from DARPA aims to boost muscles, reduce fatigue and injury (video)

Source: Engadget The US military’s dabbled with full-on robotic suits in the past, but it’s now looking at a less convoluted, more energy-efficient approach. A project called Warrior Web from DARPA aims to enhance soldier carrying capacity and minimize injuries by distributing loads better, providing better joint support and “reapply(ing) energy to enhance motion.” Such a suit would be equipped with sensors to…

Vicon Nexus SDK: Streaming Markers to MAYA

While Vicon Blade is known for its ease of integration with software such as Motion Builder and Maya, Nexus is most known for its application in Biomechanics as it has the capacity to record numerous sensors such as EMG as well as marker positions.   I wanted to look into art driven by motion capture markers, but I also wanted to…

Disney Teaches Its Animatronics Not to Be Classless Brutes

  Hyeonjun found interesting post as fellow;)   In an effort to make how robots move and interact with humans feel less awkward and uncomfortable, Disney Research, working with the Karlsruhe Institute of Technology in Germany, are developing a more natural approach to the problem by thoroughly studying how humans interact. In fact, using motion capture suits, the study was taken…

NAO humanoid robot

Nao is an autonomous, programmable humanoid robot developed by Aldebaran Robotics, a French startup company headquartered in Paris.  The robot’s development began with the launch of Project Nao in 2004. On 15 August 2007, Nao replaced Sony’s robot dog Aibo as the robot used in the Robot Soccer World Cup (Robocup) Standard Platform League (SPL), an international robotics competition. The Nao was used in RoboCup 2008 and 2009, and the NaoV3R was…

Introduction to Quadcopter Robot

<Quadcopter research At the University of Pennsylvania, prof.Vijay Kumar>   <quadcopter> A quadcoptor, also called a quadroter, is a multicopter that is lifted and propelled by four or multiple rotors. Quadrotors are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of revolving narrow-chord airfoils. Unlike most helicopters, quadrotors generally use symmetrically pitched…

(Refered Post)Robots will be FIFA champions – if they keep their eyes on the ball

The DARwIn-OP humanoid soccer-playing robot may look like a toy, but is a platform for groundbreaking artificial intelligence research.          David Budden   We already know robots manufacture cars, work in factories, even vacuum our homes – but could they form a world-beating soccer team? The question seems like ripe pickings for a movie mogul, given Hollywood’s long-standing fascination with robots.…

Hand Synergies: Mapping from human hand to robotic hand

Many robotic researcher propose a novel mapping approach to map a human grasp to a robotic grasp based on human grasp motion trajectories rather than grasp poses, because  human grasp motions usually contain complex and nonlinear patterns in a high-dimensional space. In recent advnces in neuroscience research, the control of the human hand during grasping is dominated by movement in…

Hand synergies: how to tame the complexity of grasping

Synergy에 대한 정리 최근 Neuroscience의 발전으로 인해 여러 가지 손 동작들을 손의 자유도들보다 낮은 그룹으로 표현하는 기법들이 등장하였다. 이러한 낮은 자유도의 Configuration space를 space of postural synergies 혹은 eigengrasp space으로 표현한다. 참고로, Neuroscience에서 말하는 원래의 Synergy라는 개념은 로봇 분야가 아닌 의학 분야에서 제시되었다. Muscle synergy라는 개념은 사람이 어떤 동작을 수행할 때 어떠한 근육을 쓰는지에 대해 분류한 것을 말하며, 어떠한 동작을…

Principal Component Analysis (PCA)

Pattern recognition algorithm has many usage in many field especially in robot. And relevantly used algorithm is Principal component analysis(PCA), and I introduce basic concept of PCA. Basic function of PCA is that reduce dimension of big size data which has high dimension. Of course, High dimension data is represent all of data. but it is useless to use them all. Because, they…
