Manual. GRASP Laboratory - University Of Pennsylvania. Researchers build flying robotic 'tree helicopter' (w/ Video) (PhysOrg.com) -- Many trees disperse their seeds by releasing "helicopters," those single-winged seeds that are also called "samaras.
" As these seeds fall to the ground, their wing causes them to swirl and spin in a process called autorotation, similar to man-made helicopters. In a new study, researchers have designed and built a mechanical samara whose dynamics are very similar to those of nature’s samaras. After testing the mechanical samara, the researchers then built a variety of remote-controlled robotic samaras with onboard power sources. The researchers, Evan Ulrich, Darryll Pines, and Sean Humbert from the University of Maryland, have published their study on the robotic samaras in a recent issue of Bioinspiration & Biomimetics.
The idea for building a flying robotic device based on samaras originated several years ago, after researchers attempted to scale down full-size helicopters.

I’ve found that students of all ages are interested in robots.
Given that interest, I thought it would be a good idea to bring together a number of resources about them that are accessible to English Language Learners. They make for high interest reading material, and provide good images to write about, too. The videos provide good listening practice. Here are my choices for The Best Sites To Learn About Robots: The Boston Globe’s Big Picture has a nice series of photos of Robots. The Big Picture also has another series of similar images called More Robots. The Tech Museum has a nice group of robot-related activities. LIFE has a slideshow on Japanese Robotics. LIFE also has a slideshow of famous robots from television and the movies. Robots, Robots Everywhere is an online CBS News video on Japanese robots.

Introduction of limb-mechanism robot "ASTERISK" - Arai Laboratory - OSAKA University. Introduction of limb-mechanism robot "ASTERISK" Insects have 6 legs which are generally used to walk with.
In case of need, 2 of them can also be used as arms to pick objects. Therefore we call their legs, which can also be used as arms, ''limbs''. The concept of Limb Mechanism Robot is motivated from the concept of limbs. The mechanism enables the 2 following things. Efficient operation altering limbs properly for manipulation and navigation tasks according to the situations.Miniaturization of the component by integrating the two functions into one mechanism.

Following the first lesson, you now have a basic understanding of what a robot is and what current robots normally do.
Now, it is time to decide on the type if robot you are going to build. A custom robot design often starts with a “vision” of what the robot will look like and what it will do. The types of robots possible are unlimited, though the more popular are: Land wheeled, tracked, and legged robotsAerial planes, helicopters, and blimpAquatic boats, submarines, and swimming robotsMisc. and mixed robotsStationary robot arms, and manipulators This lesson is intended to help you decide what type of robot to build to best suite your mission.
Land Land-based robots, especially the wheeled ones, are the most popular mobile robots among beginners as they usually require the least investment while providing significant exposure to robotics. Wheeled Robots Four and six wheeled robots have the advantage of using multiple drive motors (one connected to each wheel) which reduces slip. Spectrum: Omniwheels Gaining Popularity in Robotics. A recent workshop that involved some rapid development using RoboCup robots, a demonstration of KUKA's omniMove platform, and my previous posts on KUKA's youBot and the ETH Zurich's Rezero ballbot have gotten me interested in omniwheels.
Omniwheels and their variations (also called omnidirectional wheels, Swedish wheels, Mecanum wheels, or Ilon wheels) are an ingenious invention that allows a platform to move in any direction while facing any other direction. Historically, omniwheels date back to a 1919 patent by J. Grabowiecki, and have since been created in many different designs. Since their introduction by the Cornell RoboCup team in 2000 (see Raffaello D'Andrea's research paper), they have been widely used in some RoboCup categories, where they allow the soccer robots to move in a straight line, while rotating along the line in order to arrive with the desired orientation.
Vex Robotics Design System. A robot that was made using the VEX system to compete in the 2007 FTC competition.
Microsoft Robotics Developer Studio. Microsoft Robotics Developer Studio (Microsoft RDS, MRDS) is a Windows-based environment for robot control and simulation.
It is aimed at academic, hobbyist, and commercial developers and handles a wide variety of robot hardware. It requires the Microsoft Windows 7 operating system. iRobot Create. This is an unmodified iRobot Create with Command Module (the small green attachment).
The platform accepts virtually all accessories designed for iRobot's domestic robots and can also be programmed with the addition of iRobot's own Command Module (a microcontroller with a USB connector and four DE-9 expansion ports), although it is no longer being sold. Controller Due to the limitations in storage space and processing power of the iRobot Command Module, many choose to utilize an external computer in controlling the Create robot.  Since the built-in serial port supports the transmission of sensor data and can receive actuation commands, any embedded computer that supports serial communication can be used as the control computer. A number of robot interface server / simulators support the iRobot Create. The Microsoft Robotics Studio and the Webots simulation environment contain IRobot Create models. Community
