Extreme force electric linear actuator controls lumber drying
The lumber processing industry demands rugged, strong, reliable, and accurate equipment in all its operations. Conditions can be harsh. Hydraulic cylinders have been the go-to, but they have limitations, such as inconsistent control, leaks, temperature sensitivity, maintenance requirements, and lack of feedback. Now there are electric rod actuators powered by roller screws that can meet the requirements of these high-force applications. Read the Tolomatic blog.
Medium-load hexapod 6-axis motion platform
With the usability of 6-axis hexapods increasing in research and industry applications, PI introduces a new medium-load 6-axis precision motion platform, the H-825 hexapod. The H-825 provides a self-locking load capacity up to 30 kg (66 lb). The motion range is up to 55 mm (linear) and up to 38 degrees (rotation). High system precision is guaranteed by absolute encoders and an actuator resolution of 8 nanometers -- with excellent position repeatability of +/-0.1 µm and +/-2 µrad, respectively.

Sci-fi spinner: BAE Systems engineers unveil futuristic UAV concept that uses both fixed- and rotary-wing flight
The BAE Systems Adaptable UAV concept melds fixed- and rotary-wing flight technologies.
Within the next few decades, armed forces could be using unmanned aerial vehicles (UAVs) with adaptable aircraft technologies that alternate between fixed- and rotary-wing flight.
Engineers from BAE Systems, together with students from Cranfield University (Bedfordshire, U.K.), have revealed a new technology concept -- named Adaptable UAVs -- that can alternate between the two different flight modes in the same mission. When in rotary-wing mode, the UAVs can be launched and recovered from battlefields and docked on a special pole.
The Adaptable UAVs are a hybrid between fixed- and rotary-wing aircraft, and would use adaptive flight control and advanced navigation and guidance software, which would allow the aircraft to benefit from the greater speed and range afforded to fixed-wing aircraft, before alternating to rotary-wing mode to hover and achieve vertical takeoff and landing. This novel technology could allow UAVs to better adapt to evolving future battlefield situations and through working together in a swarm, tackle sophisticated air defenses, as well as operate in complex and cluttered urban environments.
In the rotary-wing mode of flight, the Adaptable UAVs can be easily and safely launched and recovered using a range of vehicles in dangerous environments that might be cluttered by personnel, other aircraft, or vehicles. The pole constrains the lateral or sideways movement of the UAV when being launched or recovered, so strong winds cannot dislodge them. This also avoids any damage to personnel nearby. This is particularly important when recovering a UAV to the aft of a ship or a land vehicle. The pole's gyro-stabilized element also ensures that it remains upright independently of the host vehicle's orientation, which may be rolling if on a ship, or in the case of a land vehicle driving up or down a slope at the time of the launch or recovery.
VIDEO: Like something right out of "Star Wars," the BAE Systems' Adaptable UAV concept is great to watch in action.
"The battlefield of the future will require novel solutions to meet emerging threats and to keep human operators safe wherever they may be," said Professor Nick Colosimo, BAE Systems' Futurist and Technologist. "The Adaptable UAVs concept and related technologies are one of a number of concepts being explored through close collaboration between industry and students in academia."
Cranfield University is one of BAE Systems Strategic University Partners. Research staff and students have explored a range of UAV technologies including research into adaptive flight control and advanced navigation and guidance software.
