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 Best Sites To Learn About Robots | Larry Ferlazzo's ... The Best Sites To Learn About Robots | Larry Ferlazzo's ... 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" - Arai Laboratory - OSAKA University 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''.

So the Cellbots team were at Google’s Cloud Robotics shipping container, prepping a demo of an “Antlerbot” – an RC car controlled by a Nexus One connected to a Sparkfun IOIO board – when disaster struck: the Antlerbot ran up under one of the doors of the shipping container, which was just too high for the sensors – but just low enough to hit the upper chassis smack in the window that showed off the IOIO board … shorting out the car beneath. So Chaitanya, Arshan, and Charles worked hard to get the bot running again, transplanting the brain from the shorted bot over to the larger Antlerbot which was going to be running on a tablet. After some surgery, they got the bot rewired, but the output was still bad: the IOIO was fried too. Then they replaced the IOIO board, and still no luck: the new board wasn’t outputting the right signals. It turns out the board was on the wrong firmware version! | Cellbots: Using Cellphones as Robotic Control Platforms | Cellbots: Using Cellphones as Robotic Control Platforms

Hivemind's Robonova Turns Triple Flips (Video) - Robots Dreams Hivemind's Robonova Turns Triple Flips (Video) - Robots Dreams 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.

A team from Portugal have created a catamaran like boat that is used for monitoring rivers. Using ROS as the operating system. The boat also uses 3D mapping, sonar and tilting laser scanner amongst other technologies. Waypoints can be set and the robot will navigate autonomously to the waypoint, while avoiding obstacles above and below the surface of the water. The boat also has a landing pad for a 6 rotor UAV that provides and aerial point of view. See the video below for a more detailed explanation. Robot Living Robot Living
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: How to Make a Robot – Lesson 2: Choosing a Robotic Platform ...

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. Spectrum: Omniwheels Gaining Popularity in Robotics
Vex Robotics Design System 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. The VEX Robotics Design System is centered around the VEX Clawbot Kit which is sold in the Dual Control Starter Kit(sold for USD $499.99).[1] This kit comes with four electric motors, 4 wheels, gears, and structural parts.[2] Additional sensors (ultrasonic,[3] line tracking,[4] optical shaft encoders,[5] bumper switches,[6] limit switches,[7] light sensors[8] integrated motor encoder modules,[9] gyroscopes,[10] accelerometers,[11] and potentiometers [12] ), wheels ( regular,[13] omni-directional,[14] and mecanum[15]), tank treads,[16] motors,[17] servos,[18] gears,[19] chain and sprocket sets,[20] partner joysticks,[21] programming software (easyC, ROBOTC, MPLab),[22] extra metal,[23] pneumatics,[24] and rechargeable battery power packs[25] can all be purchased separately.

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),[3] although it is no longer being sold. Controller[edit] 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.[citation needed] 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.[3] A number of robot interface server / simulators support the iRobot Create.
