Redundancy is not related to doubling #drivesystems sales. It's related to increase the security during critical operations in surgical robotics or aerospace applications. Have a look at this #FAULHABER tutorial on miniature #steppermotors. https://lnkd.in/dQDMTvYY

So many applications for magnets - from wind turbines, EVs, medical implants... sometimes even dual applications as well for defense systems - and in any case their technical performance is crucial for any equipment even though their weight - in grams or in euros - is so little in the balance. US gvt and DOD, thru their MCEIP, are an example of what a constant and persistent strategy to recover sovereignty means really. Their understandings of the global supply chain is clear and the actions taken to remediate to the holes in the industrial base are focused, long term and cover the wide spectrum of mine-to-magnet domestic production. Of course it's big numbers. But it's a race. And this what we need in EU also to keep up the technological development towards a reliable supply chain. After CRM Act foundations, financing strategic projects to build up our manufacturing capacities in EU will be key. #Rareearths #magnet #MagFactory #MagREEsource https://lnkd.in/eRrgujKQ

Out of step, out of time. Soon to be decommissioned. It will be interesting as the fission fuel shortage becomes real as they try to treble the industry and advances in the renewables, hydrogen grid variable generation and batteries as a system solution of energy generation for the whole of the world not just 39 countries out of 189 not just the rich but for all without weaponisation, without pollution of our waterways and without the need to bury waste that is dangerous for 1000 of tears what a waste of time you are here. Fission is an interim unlike fusion and renewables, with the grid-attached variable hydrogen generators and batteries which are deploying faster in 189 countries as opposed to the 39 that fission can Fission fuel. It is going to get tight in 100 or 80 years. Which Nuclear fission or fusion? https://lnkd.in/g36Z4k6P

Opportunity from the US DoD’s Defense Innovation Unit for “Expeditionary Hydrogen On Ship & Shore”.   Full details including the response form are available here: https://lnkd.in/gv-qdeHt   Note the short response deadline of July 25, 2024   The DoD seeks to prototype an integrated electrolysis-based H2 production, storage and distribution system capable of producing and dispensing a minimum of 20kg H2 in a 24 hour period at an efficiency using 100kW or less power.   The solution should:   Be entirely contained within a 20 foot container, to include the electrolyzer, one day’s worth of H2 storage, and any other equipment required for system operation (i.e., cooling capability). Be capable of operating on a ship or on shore, assuming sufficient and consistent availability of power. The solution should also assume sufficient access to potable water. Have onboard monitoring/control systems to provide instrument status and alarm to end users. Have H2 storage capable of delivery to systems or equipment at 350 bar (threshold) / 700 bar (objective), with an option of low-pressure delivery at 1 bar. The fill rates should be 60kg threshold and 100kg objective. Have the ability to produce H2 at a purity greater than or equal to 99.97%, in compliance with ISO 14687:2019 (H2 fuel quality – Product specification). Have an ISO 15869:2009 compliant carbon-fiber certified (U.S. Department of Transportation) pressure vessel or other certified H2 storage method shall be used as the H2 storage component. System should leverage standard and compatible connection interfaces for effective storage and distribution.  

The remarkable progress of autonomous, humanoid robots like Atlas (Boston Dynamics) cannot be understated. This paves the way for these robots, either remotely piloted by a human worker, or driven by computer software such as A.I., to take over the following tasks; - nuclear power operations, material handling, maintainance. - outdoor construction or under heat-stressed envionments (steel plants, mines etc) - military drone soldier (combat unit) - multi-role manufacturing, assembly These are indeed amazing, unprecedented times of humankind development. #technology #innovation #money

A novel inflatable robotic arm offering cost-effective long-range inspections for nuclear decommissioning has been demonstrated at Sellafield Ltd’s Engineering Centre of Excellence. Pioneering French company AirCube-Structures gonflables were awarded funding to further develop their fully articulated snake-like robot submitted in response to the Game Changers Post Operational Clean Out (POCO) challenge. The demo, organised by FIS360 Project Manager Kirstie Ryan, showcased the robust, lightweight and easily transportable inflatable solution manoeuvring through narrow ports, picking up items of various sizes and placing them into containers, replicating tasks essential for inspection and retrieval. Find out more about this challenge and the benefits of the Game Changers programme: https://bit.ly/4cS3huU This project is just one example of how robotic technology supported and funded by the Game Changers innovation programme is helping to advance decommissioning activities at Sellafield and across the NDA estate. Other examples include the HausBots wall-climbing ROV helping to inspect hard-to-reach areas of Sellafield’s built infrastructure (https://bit.ly/3UcJ389), and the slim-form robot designed by Jacobs Clean Energy to house and transport a sensor package prepared by Cerberus Nuclear to map and monitor the exterior of Sellafield’s Magnox Swarf Storage Silos (MSSS) (https://bit.ly/3NyLaz9).

In confined and hazardous environments where human access is severely limited, hyper-redundant manipulators play a crucial role in preserving operator safety and mitigating operational risks. Their numerous degrees of freedom and compact design make them particularly well-suited in the context of nuclear fusion reactors, whose distinct geometry, restricted spaces and heavy loads to be handled, pose unique challenges that conventional manipulators struggle to overcome. This paper proposes a bidirectional control interface for the teleoperation of hyper-redundant robots, with an application to the inspection and maintenance of magnetic fusion reactors. The proposed strategy provides the operator with an intuitive interface and optimises the robot configuration while reducing unnecessary moments of its bulky parts, which may impact the overall system performance and operation safety. It includes two control modes: position and velocity control, which can be selected based on the operator’s preferences. Additionally, the strategy integrates Virtual Fixtures (VFs) in both master and slave control to provide haptic feedback and prevent the slave robot from reaching singular configurations, joint and torque limits, or colliding with the environment. Tests were performed on the DTT Hyper-Redundant Manipulator which was teleoperated through a haptic device by 9 volunteers. The achieved results demonstrated that using VFs allows the robot teleoperation more efficiently and effectively, keeping it within the joint position and torque safety ranges and far from forbidden regions of the environment, while concurrently reducing the movement of the bulky parts. Have a look at "A bidirectional human-machine control interface based on virtual fixture for safe teleoperation of hyper-redundant robots" by Ludovica Capodivento, Tommaso Borzone, Tiberio Grasso and Clemente Lauretti recently published on IEEE Access.

At aHV Solutions we’ve recently developed a high voltage aerospace environment simulator that can dynamically change the test parameters that electrical components will experience during flight. We’re now able to monitor the safe clearance, creepage and partial discharge performance of a component in representative environments by dynamically adjusting air pressure, temperature, and voltage during a simulated flight path. By replicating real-life conditions that aircraft components experience during flight we will help our customers to understanding how these factors interact, pushing the boundaries of safety, performance, and reliability in future high voltage technology. Follow us on LinkedIn for regular updates on this and the many other test capabilities that we’re developing at aHV Solutions. The future of aerospace innovation and testing is here, and we’re thrilled to be a part of it! #Aerospace #Engineering #HighVoltage #Simulator #FlightSimulation #HVTesting #Aviation #Partialdischarge #Creepage #Clearance

Phobos is our high-resolution stereo vision camera, ideal for fast-rate, accurate mapping over wider areas. It uses 5-Megapixel cameras and can operate at 30 fps over a USB 3.0 interface. The cameras have a global shutter and are suitable for imaging moving targets. Phobos' results from a successful project within nuclear decommissioning, where a high-resolution solution capable of being mounted on a robot and deployed remotely, were vital criteria.
