Concept of Passive Dynamic Walking Robot

Passive dynamics refers to the dynamical behavior of actuators, robots, or organisms when not drawing energy from a supply (e.g., batteries, fuel, ATP). Depending on the application, considering or altering the passive dynamics of a powered system can have drastic effects on performance, particularly energy economy, stability, and task bandwidth. Devices using no power source are considered “passive,” and their…

SandFlea – Leaps Small Buildings in a Single Bound

Sand Flea is an 11 pound robot that drives like an RC car on flat terrain, but can jump 30 ft into the air to overcome obstacles.  That is high enough to jump over a compound wall, onto the roof of a house, up a set of stairs or into a second story window.  The robot uses gyro stabilization to…

Efficient Generation of Motion Transitions using Spacetime Constraints

This paper describes the application of space time constraints to creating transitions between segments of human body motion. The motion transition generation uses a combination of spacetime constraints and inverse kinematic constraints to generate seamless and dynamically plausible transitions between motion segments. We use a fast recursive dynamics formulation which makes it possible to use spacetime constraints on systems with many degrees of…

ATLAS: Performance Professional Comes to Socks

I found this great startup project that has created a new sock.  While the DYROS lab has been doing work on walking and shoe recognition, some people have thought about how this research can influence shoe design itself.  I am not too sure about the research methods used in this product, but it at least sounds convincing.  When talking to…

Robot legs accurately mimic human movement

Researchers from the University of Arizona has built a pair of robotic legs that mimics our own. While bipedal movement is nothing new in robotics — Honda has had a free-walking robot for some time now — the research team describes its creation as “biologically accurate.” It developed a simplified software equivalent of a central pattern generator (CPG), the neural…

Robot Scout Finds Fires With 3D Thermal Imaging

  Source: IEEE Spectrum We hear about lots of robots that could potentially be used for “search and rescue” or “disaster relief,” because that’s kind of what you say when you’ve made a robot that doesn’t have a commercial or military application but you still need to come up with some task that it might be useful for. It’s much…

Linkbot: That Modular Robot You’ve Always Wanted Is Now on Kickstarter

  Source: IEEE Spectrum This Linkbot looks like LEGO. We can make many kinds of robots as we want.The application of Linkbot  runs on Windows, Mac, and Linux which provides a graphical interface for controlling your Linkbots(and open source). It is easy to develop with robot everyone. (NAO have to do additional work to run on Windows with C++.)   By Evan…

Swiss scientists create catbot: a robot that runs like a cat (video)

Source: Engadget Someone call MIT’s researchers and tell them their terrifying cheetah robot has a long-lost teensy sibling in Switzerland. Developed in the laboratories of the École Polytechnique Fédérale de Lausanne, the “cheetah-cub robot” is a four-legged metallic critter modeled after a house cat. The scientists focused on designing legs that can move like our feline friends’, paying particular attention to their stability…
