Monkey thinks robotic arm into action - LiveScience - MSNBC.com Robotic arms used by amputees are typically controlled by moving some other part of the body, like the opposite arm. The robotic arm is about the size of a child’s, with a fully functional shoulder and elbow, as well as a simple gripper that can hold a piece of fruit or vegetable. To control the robotic arm, 96 electrodes — each thinner than a human hair — are attached to the monkey’s motor cortex, a region of the brain responsible for voluntary movement. www.msnbc.msn.com /id/6989239   (750 words)

Armwrestling Match of EAP Robotic Arm Against Human - Wikipedia, the free encyclopedia The Armwrestling Match of EAP Robotic Arm Against Human (AMERAH) is a challenge posed by Yosef Bar-Cohen of the JPL in 1999. The initial challenge is to create a simple human-like robotic arm which, using electroactive polymers (EAP) as artificial muscles, can beat a human opponent (e.g., a high school student) in an arm wrestling match. The ultimate goal, however, is to create an arm using EAP as similar as possible to a human arm, which can beat any human in an arm wrestling competition. en.wikipedia.org /wiki/Armwrestling_Match_of_EAP_Robotic_Arm_Against_Human   (268 words)

Robotic Arm The mount from the base to the arm is located about 1 inch up the arm from the arm motor. The motor for swiveling the arm on the base is also reduction geared and belt driven. When a light colored object is placed on the platform, the robot senses that it is not fl and makes a rude noise to suggest that a fl object should replace the white one. www.fogg.cc /robots/larm1.htm   (684 words)

Build A Robotic Arm   (Site not responding. Last check: 2007-11-01) Robots with cameras are good tools for creating "telepresence" in a harsh environment. Robots that interact with their environments are often equipped with a robotic arm, as is "MARS ONE", a grasping device that lets the robot pick up and manipulate things. The arm will be operated like the "Robot built of Humans" _ the Manipulator is "blind" and must take direction from a "Brain" or Human Operator. cmex.ihmc.us /CMEXCD/NSTA95/TeachCen/RobArm.htm   (435 words)

SPACE.com -- The Robot Touch: How Spirit Keeps Mars Within Reach Spirit's robotic arm, known formally as the Instrument Deployment Device (IDD), is a mechanized mass of scientific instruments that reaches just over three feet (almost one meter) out in front of the rover. But the arm structure is strong, made of hollow titanium, that keeps the scientific package steady and accurate as it shifts from one instrument to another, he added. On the robot arm with the microscopic imager is the rock abrasion tool (RAT), a grinder that shears away the surface layers of a rock sample to buff away accumulated dust or weathering effects. www.space.com /businesstechnology/technology/spiritarm_techwed_040121.html   (1274 words)

Society for Neuroscience | Robotic Limbs   (Site not responding. Last check: 2007-11-01) Armed with this information, researchers began to develop computer programs that could read and decode the language and then set off an intended movement in a robotic limb. For example, in early work, one group trained monkeys that had both arms restrained to use their brain power to make a cursor, a sort of animated arm, reach toward a target in a virtual reality environment. With further advances, they hope that disabled people will be able to incorporate the robotic devices into part of a representation of their body and regain lost movement abilities. web.sfn.org /index.cfm?pagename=brainBriefings_roboticLimbs   (852 words)

Heart attack, heart disease, and cholesterol information from HealthCentersOnline - HeartCenterOnline   (Site not responding. Last check: 2007-11-01) The effectiveness of the Bi-Manu-Track robotic arm trainer (Reha-Stim Company, Berlin), which helps the arm muscles to contract and flex, was compared with electric stimulation, which applies electrical pulses to the affected limb. At the end of the 6-week trial, the average motor function score was 24.6 in the arm trainer group and 10.4 in the electrical stimulation group. The greater improvement achieved with the arm trainer "is probably attributable to the greater number of repetitions and the bilateral approach," Hesse's group concludes. heart.healthcentersonline.com /newsstories/roboticarmcanimprovemotorcontrolafter.cfm   (505 words)

washingtonpost.com: Monkeys Control Robotic Arm With Brain Implants Scientists in North Carolina have built a brain implant that lets monkeys control a robotic arm with their thoughts, marking the first time that mental intentions have been harnessed to move a mechanical object. In the new experiments, monkeys with wires running from their brains to a robotic arm were able to use their thoughts to make the arm perform tasks. The arm was kept in a separate room -- "If you put a 50-kilogram robot in front of them, they get very nervous," Nicolelis said -- but the monkeys could track their progress by watching a schematic representation of the arm and its motions on a video screen. www.washingtonpost.com /ac2/wp-dyn/A17434-2003Oct12?language=printer   (1326 words)

OWI 007 Robotic Arm Trainer The OWI Robotic Arm Trainer is a good introductory kit, requiring only a screwdriver to assemble. Assembly of this robot arm will give you a sense for the mechanical challenges involved in creating robotic manipulators, and the see-through plastic allows you to observe the motion of the gears even after the kit is assembled. This robot arm does not include any sensors or electronics, but because each axis is powered by a separate DC motor, it is possible to add your own electronics to control the arm through a computer or microcontroller. www.pololu.com /products/elenco/0325   (185 words)

CNN.com - Sci-Tech - Spacewalkers extend robotic arm's reach - April 24, 2001 Two astronauts from the space shuttle Endeavour, which is docked with Alpha, ventured out Tuesday on their second spacewalk to finish wiring the billion-dollar Canadian-built robot arm to the station. The arm is 58-foot long, weighs 3,618 pounds and is made of steel, aluminum and graphite epoxy. After the new station arm was successfully attached to Alpha on Monday, Parazynski and Italian astronaut Umberto Guidoni cranked up the shuttle's 50-foot robot arm and latched onto an Italian-built cargo carrier, named Raffaello, in Endeavour's payload bay. archives.cnn.com /2001/TECH/space/04/24/shuttle.spacestation/index.html   (750 words)
