This Robot’s Acrobatic Leaps Are the Coolest Thing You’ll See Today

 I found this article from IEEE Spectrum website, this robot was presented at ICRA this year by Aaron M. Johnson fro m the University of Pennsylvania’s Kod Lab. which has a unique legs structure caught my interest.  Legs have an advantage over wheels when it comes to rough terrain, but the articulated legs often found on walking robots require complex, specialized…

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…

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…
