Maintenance system ‘spots 99% of potential problems’
Bosch Rexroth has developed a predictive maintenance technology that, it claims, will detect 99% of potential issues, compared to 43% for experts using traditional condition-monitoring techniques. The technology, called ODiN, uses machine learning to generate knowledge about the health of equipment from sensor data, and to produce reliable predictions about likely times to failure.
Micro-compressor is ‘the first innovation for 100 years’
A Scottish company claims to have developed world’s smallest high-pressure, low-vibration clean-air compressor. Edinburgh-based Vert Rotors adds that its tiny device is the first real innovation in micro-compressor technology for a century.
Servomotor with built-in screw drive is ‘unique’
The German miniature servomotor specialist Wittenstein cyber motor has come up with a “unique” servomotor design which has a screw drive built into its housing. The motor, spindle drive, linear guide and encoder system form a ready-to-mount integrated linear actuator system suitable for use as a dynamic positioning axis, especially where space is limited. When combined with servo controls, the motors can form servo axes with multiple fieldbus interfaces.
Linear transfer system carries on-board power
Mitsubishi Electric is the latest automation supplier to announce a linear transfer system for production lines. It has teamed up with the German production technology specialist, APT Automation, to develop a system called Smart Carriage that “uniquely” provides 240V AC and 24VC supplies on board its carriages, which can be used to power sensors, grippers and actuators, and to collect and store data.
NASA's glass gears have cracking potential
US researchers, led by scientists and engineers from NASA’s Jet Propulsion Laboratory in California, are developing gears made out of special materials that that can act both as a metal and as a glass. The materials can operate efficiently without lubricants in extremely cold conditions, such as those found on the surface of planets and moons. They could also slash the cost of strain-wave gears used in applications such as robotics.
Open control platform supports your favourite tools
At the recent SPS IPC Drives show, Phoenix Contact unveiled a “future-proof” open control platform, called PLCnext, that will allow engineers from different disciplines to work together simultaneously on projects, each in their preferred development environments. They can continue to use their chosen programming tools – such as Visual Studio, Eclipse and Matlab Simulink – and to link their program code, saving time and reducing the risk of errors.
‘Basic’ 100Mbit version of CC-Link IE will cut costs
CLPA – the CC-Link Partner Association – has announced an addition to its CC-Link IE protocol that will allow device vendors to add CC-Link IE compatibility to any product with a 100Mbit Ethernet port. The new version, known as CC-Link IE Field Network Basic – or “Basic Mode” – can be implemented on devices or master controllers using software alone, allowing it to be added to existing products without making any hardware modifications. CLPA says that this will reduce the cost of development and time-to-market “significantly”.
Future enclosures will have built-in cooling 'like a fridge'
Ritttal used the recent SPS IPC Drives exhibition to preview its vision of the future where enclosures will have built-in cooling systems, avoiding the need to assemble cooling systems on enclosure roofs or side panels. It showed two prototypes: one with the cooling system at the top; the other at the side.
$18m backing for GE spin-off that ‘re-invents the switch’
A new US company, spun off from GE’s Global Research Center, claims to have re-invented the electronic switch, with a device that can handle kilowatts of power, yet offers the size, speed, cost, and reliability attractions of solid-state devices.
Free app could save manufacturers more than $1m a year
Rockwell Automation has released a free app for mobile devices such as smartphones that will allow engineering teams to collaborate and share knowledge, view live production statistics, interact with machine alarms and troubleshoot machines. Rockwell estimates that each team member using the FactoryTalk TeamOne app could save 1% of their workday, or 33 seconds per shift – equivalent to an annual saving of more than $1.4m for a manufacturer with about 2,000 production staff.
Automation giants back OPC UA TSN to unify comms
More than ten leading automation suppliers have joined forces to back OPC UA over Time Sensitive Networking (TSN) as a unifying communication system for use between industrial controllers and to the cloud. The companies – which include ABB, Bosch Rexroth, B&R, Cisco, General Electric, Kuka, National Instruments (NI), Parker Hannifin, Schneider Electric, SEW-Eurodrive and TTTech – intend to support OPC UA TSN in their future products.
I/O board will allow Raspberry Pi to control motors
The Californian industrial automation manufacturer Opto 22 has developed a digital I/O board for the low-cost Raspberry Pi computer that will allow the Pi to monitor, control, and automate devices that were previously beyond the capabilities of its built-in 3.3V DC GPIO sensing and control connector. The new Digital I/O Carrier Board can be used to sense or switch up to 16 electrical loads up to 3A, 2.5–280V AC/DC, allowing it to monitor and control electrical loads such as motors, pumps, and sensors.
X-Y gantry has an axis that rotates through 20 degrees
The US motion engineer Intellidrives has developed a large-area X-Y gantry in which one of the axes can be rotated through more than 20 degrees. This novel approach to kinematics allows large relative motions of independent (X1 and X2) parallel axes to control orthogonality in the X-Y plane, or to introduce large theta rotation of the Y-axis about the X1 and X2 axes, as well as rotating the Y-axis around a virtual programmable point.
£1.2m project aims to turn waste heat into electricity
A UK consortium has embarked on a three-year research programme to explore the potential for converting low-temperature waste heat into useful electrical power. The project, led by steam engineering specialist Spirax Sarco, has received a £1.24m grant from the UK’s innovation agency, Innovate UK.
3D smart glasses help to cut maintenance workloads
Mitsubishi Electric has developed a technology that allows maintenance technicians wearing 3D augmented reality (AR) glasses to confirm the order of an inspection and then enter the results by voice. It says that the technology will cut workloads and help to avoid entry errors because information can be entered reliably, even in noisy environments.
