Pneumatic Cylinders Used in Robotic “Hand”

Robotics are now and have been an inextricable aspect of American industry, performing tasks as varied as the robots themselves. Robots can, in most cases, accommodate greater production speeds, and can be re-tasked for any future changes or even re-assigned to a different application. As technology advances, and demand and expectations grow, robotic systems are being developed displaying greater abilities in precision control and dexterity. The printing and packaging industries are no different, and when Roskam Automatic Machine (Birmingham, AL) developed a robotic end effector — what amounts to a robotic “hand”— to integrate with other robotic systems (industrial manipulators, or the “arms”), it relied on the pneumatic devices from Parker Hannifin (Cleveland, OH) to help run the robotic “fingers.”

Water Jets and Lasers Cut Through Electronic Industry’s Problems

Semiconductor manufacturers need the flexibility of a wafer-cutting machine that supports various wafer sizes and cuts them without the mechanical and thermal damage often seen with traditional cutting methods, including the mechanical stress that occurs with conventional sawing, or the contamination and/or ablated material caused by laser cutting. Employing a dicing process that makes the wafers less prone to breakage would allow manufacturers to introduce thinner wafers into the production line, thereby increasing the number of functions on a given device. A machine that cuts lasers without a heat-affected zone would also offer efficiency advantages to manufacturers.

Software Used to Control Master-Slave Haptics Experiment

Haptics, also known as “force feedback teleoperation,” attempts to provide environmental interactions through a robotic system. Users mimic these interactions with robotic arms. By varying the amount of force the haptic devices exhibit, a user can achieve the sensation of interacting with the system. As it allows a user to interface with a remote or virtual environment, the goal of haptics is to augment a user’s sensory feedback while performing a given task. In order to construct safer haptic systems, researchers at the Intelligent Machine Dynamics Laboratory (IMDL) at the Georgia Institute of Technology (Atlanta, GA) have built a series of master-slave devices, and utilize National Instruments’ (Austin, TX) LabVIEW 8.0 software and its various toolkits to control all feedback calculations, communication, control, and simulation, with the objective to investigate control difficulties that occur using a passive master with an energetically active slave.

Motor Used to Stabilize Remote-Controlled Camera Crane

It is a staple of the summer box office blockbuster: the car chase. Car chases have not only become a vital component of an action movie, they have also had to evolve, with audiences demanding even more thrills. To put the audience directly into the flow of traffic, studio executives turn to companies like Adventure Equipment, whose Ultimate Arm, a gyrostablized, camera-mounted, remote-controlled crane system attached to an SUV, gets in where the action is. Maxon Motors’ (Fall River MA) RE40 motor is used to maneuver the camera, capturing all the adrenaline-pumping moments.

Plasma Cutter Utilizes Motor for Gantry Control

To cut through metal and other materials, a plasma cutter sends an arc of electricity through a high-speed jet of an inert gas. When electricity and gas meet, plasma is formed, hot enough to melt through sheet metal, and still moving fast enough to blast molten metal away from the cut. When engineers at Dynatorch (Padukah, KY) began to design a line of plasma and oxy-acetylene cutting machines, they utilized the SM2315D SmartMotor from Animatics (Santa Clara, CA) to operate the gantry, where the torch is mounted. To avoid the warping, kinking, or scorching that can occur when metal is improperly heated, the gantry and torch must maintain a fixed distance from whatever is being cut.

Hundreds of Gearmotors Drive Times Square Scrolling Sign

With a zoning ordinance requiring businesses to throw up big, bright, eye-catching signs, Times Square in New York City has an illuminated-sign density rivaling Las Vegas. When Toys “R” Us moved into the neighborhood, it contacted Revolution Display Systems, (Toronto, Canada) to create a motor-controlled, synchronous, contiguous moving image that would constitute the location’s storefront. The resulting 165-module “Building Board” is the first large-format scroller matrix in the world.

Drive Retrofit Update Enables Smoke-Removal System at Atlanta Airport

When the City of Atlanta finalized plans for the capital-improvement project at Hartsfield-Jackson Atlanta International Airport, an integral part of the 10-year, $5.4 billion project included upgrading the ventilation system of the underground Automated People Mover (APM). The APM’s previous ventilation system was adequate when the APM served the A, B, C, and D Concourses. When Concourse E was added and the APM extended — now 3.5 miles long, handling 128,000 passengers an hour — the fans required upgrading to handle additional flow and pressure to meet National Fire Protection Association standards for emergency smoke evacuation. The $3.4-million set up and installation contract for mechanical and electrical equipment was awarded to W.B. Wallis & Co. (Atlanta, GA).
