A natural samara is positioned next to the smallest and lightest robotic samara constructed to date. The wing of the vehicle is similar in size to a natural samara wing. Image credit: Ulrich, et al. (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.
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 .
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''.
About a week ago, "Thor" - the Robonova-1 robot modified by "Hivemind" - surprised us all by beautifully executing a full forward flip. Now Hivemind has Thor turning triple flips in a continuous series that's almost without hesitation. From the video below it really appears as if Hivemind has his robot in training for a real Robo-Olympics type gymnastics event. Keep in mind that Thor is not a stock, off-the-shelf, Robonova-1. Hivemind has invested a lot of time, skill and effort in increasing the robots degrees of freedom from the standard 16 to a total of 21.
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:
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 .
A robot that was made using the VEX system to compete in the 2007 FTC competition The VEX Robotics Design System is a robotic kit intended to introduce students as well as adults to the world of robotics.
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.
This is an unmodified iRobot Create with Command Module (the small green attachment). iRobot Create is a hobbyist robot manufactured by iRobot that is based on the Roomba platform and was introduced in 2007. However, iRobot Create is explicitly designed for robotics development, rather than simply hacking the Roomba. [ 1 ] [ 2 ] In place of the vacuum hardware of the Roomba, the Create includes a cargo bay which houses a 25 pin port that can be used for digital and analog input and output. [ 1 ] [ 2 ] The Create also possesses a serial port through which sensor data can be read and motor commands can be issued using the "iRobot Roomba Open Interface protocol". [ 3 ] 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), [ 3 ] although it is no longer being sold.
