Automation-Direct has added the new SQ series table lifting systems from Ergoswiss. These lifting systems use electrically driven columns that allow the operator to reposition the height of a worktable, conveyor, etc. to meet specific requirements. In doing so, the operator can perform their tasks in a more comfortable working posture, helping to reduce work-related injuries. These systems are all electric (no hydraulic mess or manual hand cranks), and each lifting column features a housed motor and screw drive to perform the needed height adjustments.

The GVCM-032-025-02M Linear Voice Coil Servo Motor is the first of a new series of non-commutated, brushless linear servo motors from Moticont. This clean and quiet unit has a 12.7-mm stroke with built-in shaft and bearing, a continuous high-force-to-size ratio of 9.3 N (2.1 lb), and 29.3 N (6.6 lb) of peak force at a 10% duty cycle. Features include: high reliability, high speed, zero cogging, high acceleration/deceleration, and, when used in a servo loop, very high accuracy and repeatability. An ideal choice for: haptic feedback, medical devices, laser machining and drilling, work holding and clamping, scanners, optical focusing, testing, sorting, and assembly.

With the help of a motion controller and a stepper driver, all stepper motor linear actuators can be programmed to position a load to a precise location. However, standard configurations do not provide a feedback mechanism that tells the operator whether the move is completed or not. Adding an encoder can be an effective and simple solution to get real-time motion feedback about your application.

QinetiQ North America's Dragon Runner 10 (DR10) has been selected by the Joint Improvised Explosive Device Defeat Organization (JIEDDO) in response to a Joint Urgent Operations Needs Statement (JUONS) for lightweight, throwable robots. This order for more than 100 DR10 robots represents the first significant U.S. military procurement of this new class of robot from QinetiQ.
With multiple cameras and payload options, DR10 is ideal for reconnaissance and surveillance missions to support small military units, patrols, and first-responder teams. At just over 10 lb, DR10 is small enough to carry in an assault pack and rugged enough to throw into buildings and hostile environments. DR10 can climb stairs, carry significant payloads, and maintain effective wireless communication over long distances.
To protect warfighter lives, DR10 is thrown or driven into potentially hostile environments to assess situations remotely, before committing personnel. DR10 provides rapid situational awareness with visual reports back to its operator using day and night sensors. With optional accessories, this modular robot can also carry out other critical missions such as delivering counter-IED charges and remote sensors.
The JIEDDO order includes DR10 robots and spare parts at a contract value of $5.3 million. Initial deliveries were made within four weeks of contract award in late December, and follow-on deliveries will continue into early spring 2012.
Multiple payloads are available, including a variety of sensors, radios, cameras, and robotic arms. DR10 can be equipped with either tracked or wheeled mobility options to negotiate various types of terrain. When thrown, DR10 has the ability to automatically flip video images, antennae, and controls upon landing. DR10 is 15 in. long, 13.5 in. wide, and 5.8 in. tall.
