Autonomous mobile robots do heavier lifting
ROEQ has launched two new top modules and accompanying accessories designed to boost the payload and lifting capabilities of autonomous mobile robots (AMRs) from industry leader Mobile Industrial Robots (MiR). Capable of handling total payloads of up to 1,500 kg (3,307 lb), the new ROEQ top module TMS-C1500 combined with the new S-Cart1500W shelf cart greatly increases the payload capabilities of MiR's MiR500, MiR600, MiR1000, and MiR1350 AMRs. Eliminating the need for a docking station, the TMS-C1500 can pick up and drop off the shelf cart in free space and with precision. The AMR is never left idling, and it can simply drop off the cart and immediately go and pick up a new one. ROEQ has also launched the top module TML200 with a stroke of 40 mm that can lift and transport crates, pallets, racks, and ROEQ shelf carts.

Inductive vs. optical vs. magnetic encoders: How to choose
It makes sense that when there isn't a need to spend on a high-end optical encoder, the most common thought is to look directly to magnetic encoders. According to HEIDENHAIN, sometimes that's the right move, but when using an inductive encoder is an available option, your search shouldn't be limited to magnetic or optical. Confused? You won't be after reading this informative HEIDENHAIN blog.

How to avoid premature linear screw actuator failure
At their core, electric linear screw actuators deploy mechanical technology such as ball bearings, ball screws, and roller screws that have a finite life. These components do not last forever -- even though that is the expectation of some customers. But how long will an actuator really last? Tolomatic engineers provide a way to calculate, estimate, and size the electric linear screw actuator to achieve the desired life for your application.

Electromechanical linear actuators: High power in small packages
Packing higher motion control capability into a more compact envelope has given rise to a new generation of high power-density actuators. Machine designers for mobile-off-highway, material handling, factory automation, and other power-hungry applications can now get electrical actuators from Thomson that provide up to 2 kN/450 lbf with advanced onboard electronics ̶-- all in a component that requires less space and is more cost efficient than hydraulic or heavier-duty electromechanical actuators that might previously have been deployed for such applications.

New backlash-free threaded nut for external linear actuators
Nanotec now offers radially pre-loaded threaded nuts for its external linear actuators with flange size 42 mm (NEMA 17). These backlash-free nuts automatically readjust themselves during operation and achieve high positioning accuracy and repeatability. Compared to simple, axially pre-loaded nuts, they are characterized by a lower frictional torque and higher efficiency. The nuts are currently offered in combination with the linear actuators of the LSA42 series from Nanotec. These actuators are available in many lengths and thread leads. They come with ACME or trapezoidal thread and facilitate the construction of space-saving linear axes.

Northrop Grumman and Raytheon successfully test fire scramjet hypersonic weapon
Raytheon Missiles & Defense, in partnership with Northrop Grumman, successfully completed the first flight test of a scramjet-powered Hypersonic Air-breathing Weapon Concept, or HAWC, for the Defense Advanced Research Projects Agency (DARPA) and the U.S. Air Force in September.
The companies are on track to deliver a prototype system to the U.S. Department of Defense.
During the test, HAWC was carried under the wing of an aircraft before it was released. Seconds later, a solid rocket motor boosted HAWC to supersonic speeds, where the scramjet engine ignited and accelerated the missile, enabling it to reach hypersonic flight.
Raytheon Missiles & Defense is using its decades of expertise to mature its hypersonic systems rapidly and efficiently. Much of the company's work is centered on modeling simulation and faster prototype testing on systems like the Hypersonic Air-breathing Weapon.
The test validates the ability of HAWC's airframe and propulsion system to reach and cruise at hypersonic speeds.
"This is a history-making moment, and this success paves the way for an affordable, long-range hypersonic system in the near term to strengthen national security," said Colin Whelan, vice president of Advanced Technology at Raytheon Missiles & Defense. "This test proves we can deliver the first operational hypersonic scramjet, providing a significant increase in warfighting capabilities."
Scramjet engines use high vehicle speed to forcibly compress incoming air before combustion to enable sustained flight at hypersonic speeds -- Mach 5 or greater -- which is five times the speed of sound. By traveling at these speeds, hypersonic weapons like HAWC are able to reach their targets more quickly than traditional missiles, allowing them to potentially evade defense systems.
"We have reached a milestone in delivering a game-changing capability to the warfighter," said Dan Olson, vice president and general manager of Weapon Systems Division for Northrop Grumman. "Decades of learning advanced manufacturing techniques and industry partnerships helped us define what is now possible."
Raytheon Technologies and Northrop Grumman signed a teaming agreement last year to develop, produce, and integrate Northrop Grumman's scramjet engines onto Raytheon's air-breathing hypersonic weapons. The agreement enables both companies to combine their capabilities to accelerate development and demonstrate readiness to produce the next generation of tactical missile systems.
