Motion Control with Precision Noncontact Displacement Sensors

Noncontact displacement sensors are used in measurement applications where surfaces or processes do not allow contact and demand high precision. Capacitive, confocal, eddy-current, and laser triangulation sensors have proven themselves in applications that incorporate motion systems. Noncontact sensors are available in many different versions. However, sensor range decreases significantly as the required precision increases.

Vacuum System Powers Modular Soft Robot

Researchers at the Ecole Polytechnique Federale de Lausanne (EPFL) have created the first functional robot powered entirely by vacuum. It is made of soft building blocks that move by having air sucked out of them. The robot can be reconfigured to perform different tasks, like climbing vertical walls and grabbing objects.

Pick-and-Place System Delivers Improved Productivity and Safety

Deciding between a gantry and a robot for your application isn’t always as clear-cut as it may seem. To automate a simple, yet time-consuming and potentially dangerous task in its factory, a company that makes particleboards weighed the benefits of using a gantry system against a robot system.

Trends in Hydraulic Filtration

Proper filtration plays an important role in ensuring that hydraulic systems operate trouble-free. High-performance filters maintain the cleanliness of the hydraulic fluid over its entire service life. In addition, designers are faced with ever-changing application requirements — longer filter change intervals, higher operating safety, increased separation efficiencies, and increased compatibility with the new generation of hydraulic oils. Following is an overview of some important technologies and trends in the industry, and their impact on users of hydraulic systems.

Miniature Linear Bearings Help Prolong Curiosity’s Mars Mission

The launch, landing, and overall mission of NASA’s Mars Science Laboratory (MSL) is arguably one of the most daring — and successful — space exploration endeavors ever undertaken. After a successful landing at Gale Crater on August 6, 2012, MSL’s Curiosity rover has already surpassed its 23-month mission target, and it continues to transmit informative images of the Martian surface on a daily basis.

Soft Robotic Gripper Manipulates Objects Without Training

An engineering team at the University of California San Diego has designed and built a gripper that can pick up and manipulate objects without needing to see them and without being trained. The gripper is unique because it brings together three different capabilities; it can twist objects, it can sense objects, and it can build models of the objects it’s manipulating. This allows the gripper to operate in low light and low-visibility conditions, for example.

Multi-Legged Robot Reconfigures in Real Time

Scientists at Disney Research have developed a modular, reconfigurable legged robot named Snapbot that can move forward, interact with its environment, and perform other tasks based on a number of possible configurations. This system identifies its current configuration using only internal sensors, and utilizes a corresponding motion strategy to complete its task. The motion strategy changes as it is physically reconfigured in real time.

New Products: December 2017 Motion Design

Corrosion-Resistant Valve

GF Piping Systems (Irvine, CA) introduced a corrosion-resistant pneumatic diaphragm valve for highly corrosive dosing and open/close applications. The Type 604/605 pneumatically actuated dosing valve is designed and tested to surpass two million lifecycles. The 1/2” (d20) size 604/605 valve is available in PVC, CPVC, PROGEF Standard PP, and SYGEF; in standard PVDF body materials with a wide variety of end connections; and custom assemblies. The valve is pressure-rated at 90 psi unidirectional with operating temperatures ranging from -4 to 284 °F, depending on body material. A threaded bonnet design eliminates both the need for metallic body bolts and re-torqueing after hot line shutdowns. Oversized pneumatic ports decrease cycle time to maintain accurate dosing with minimal overrun.

Paper-Folding Techniques Expand Compacted Spacecraft

Origami has once again inspired engineers at NASA’s Jet Propulsion Laboratory (JPL). Besides aesthetic beauty, the Japanese tradition of paper-folding addresses a persistent problem faced by JPL engineers: how do you pack the greatest amount of spacecraft into the smallest volume possible?

Webb Telescope Actuators Move with Microscopic Accuracy

The James Webb Space Telescope will be the most powerful space telescope ever built. With a 21-foot diameter, the telescope’s primary mirror is six times larger than the one used by the Hubble Space Telescope. In order for such a large mirror to travel into space, it has to be broken up into multiple segments; in this case, 18 of them. But for the 18 to act as one primary mirror, they have to be adjusted while in orbit.
