In the picture:It has the ability to morph (change shape), propel itself and turn quickly in water (i.e. super-manoeuvrability) efficiently and silently, lending itself to future possibilities in surveillance and inspection. Scientists in Singapore have developed a new octopus-inspired robot which can zip through water 10 times its body length within one second, in an ultra-efficient manner. This first-ever ultra-fast propulsion and super-manoeuvrability demonstrated in underwater vehicles is unprecedented; and is the work of researchers and an engineer from the Singapore-MIT Alliance for Research and Technology (SMART). This ground-breaking research validates the physics of shape change (that forms the basis of jet propulsion of cephalopods) to give additional thrust to underwater vehicles. Inspired by the speed at which cephalopods like the octopus, flee from danger by inflating its mantle cavity with water to a bluff-body shape and then quickly expelling it to dart away, the researchers started building an octopus-inspired robot in November 2013. The end result is a polycarbonate 3D printed streamlined skeleton which had no moving parts and no energy storage device other than a thin elastic outer membrane. It works like blowing up a balloon and then releasing it to fly around the room. The 27cm long robot is inflated with water and once released, rapidly deflates by shooting the water out through an aperture at its base to power its propulsion. As the rocket contracts, it can achieve more than 2.6 times the thrust of a rigid rocket doing the same manoeuvre, while creating minimum turbulence – an important feature in underwater research / survey vehicles. The skeleton within the robot keeps the final shape streamlined, while fins at the tail, help in stabilisation. When a fish escapes by swimming fast, it bends its body and zooms through the water, losing some energy to the surrounding […]

For the second consecutive year, Hamilton-based Dairy Automation Limited (DAL) has been named finalist in two categories of the New Zealand Hi-Tech Awards.  The subsidiary of farmer-owned co-operative LIC specialises in manufacturing sensor technology systems for the dairy shed, for real-time on-farm milk analysis.  Its CellSense system is a finalist for the Endace Innovative Hi-Tech Hardware Product award, and YieldSense system is up for the New Zealand Trade and Enterprise Innovative Agritech Product award.  CellSense meters measure somatic cell counts for early detection of mastitis. It is the only fully automated in-shed in-line somatic cell count sensor in the world.  YieldSense is a combined full flow milk meter and milk component measurement device for the individual measurement of cow milk in the dairy shed. The six-in-one sensor analyses yield, fat, protein, lactose, conductivity and plant wash.  Both systems provide real-time results while a cow is being milked, that farmers can utilise to increase production, reduce treatment costs and make more informed herd management decisions. They also integrate with LIC’s Protrack automation systems, so any cows identified by the sensor systems as requiring closer inspection or further treatment will be alerted to the farmer and automatically drafted at the end of milking.  The sensors are highly regarded by farmers in New Zealand and demand from farmers overseas is increasing too. Sensor technology has the potential to revolutionise traditional herd testing practices.    

In the picture:The new ESPRIT 2015 5-Axis Chamfering strategy chamfers edges lying along a 3D curve.           ESPRIT helps increase productivity for a full range of machine tool applications by generating more efficient toolpaths while also saving time by providing substantial improvements in computer numerical control (CNC) programming productivity. Besides increasing productivity, the release also provides many new and improved features specifically in the areas of intelligent machining, strategic machining, CAD-CAM data exchange and Cloud-Enabled CAM.: ESPRIT 2015 5 – Axis Blade Roughing cycle makes it possible to completely machine blades in a single setup. Intelligent Machining Intelligent machining features in ESPRIT 2015 accelerates the machining process by providing new and unique 5-Axis cycles that reduce cycle time. This makes it possible to completely machine blades in a single setup. ESPRIT´s 5-Axis Blade Roughing tool motion is morphed across the blade from any size stock shape to uniformly offset stock allowance so it can be immediately followed by a finishing cycle. ESPRIT 2015 offers unique features in 5-axis to make complex machining more efficient, allowing users to have more tool path options with features like blade roughing and chamfering.» said Cedric Simard, Global Marketing & Communication Director of DP Technology. »ESPRIT 2015 blade roughing enables users to remove material down to uniform stock around the blade and eliminates the need to follow semi-finish cycles. Users in the aerospace, energy, medical and automotive industries will benefit the most from these time-saving operations for precision parts.» The Port Roughing cycle, another intelligent machining improvement in ESPRIT 2015, is a brand new 5-Axis cycle. It creates a 5-axis roughing operation to remove the material inside an area where the tool must enter through a restricted opening. The shape of the toolpath is an offset of the port surfaces, starting […]

Industrial automation specialists Design Energy, has announced the launch of the new UR3 robot from Universal Robots into the New Zealand Market. The UR3, which went through a three-year development phase, is an affordable tabletop robot that has a payload of 3kg and weighs a mere 11kg. It allows for 360-degree rotation on all wrist joints and infinite rotation on the end joint, ideal for tightening fasteners. The size and price point of the UR3 is proving to be a great first step for any company looking towards automation. The user friendly touchscreen teach-pendant removes the steep learning curve associated with programming a typical 6-axis robot. The light-weight compact robot can easily be moved around a number of processes to increase its utilisation and significantly reduce the payback period, which on average is less than 195 days. Mike Shatford the Director of Design Energy can see an exciting opportunity for manufacturers who have not looked to automation previously, due the cost of the hardware. “The new UR3 from Universal has significantly lowered the price of automating a process using a 6-axis robot. Manufacturers can now introduce an industrial robot into production at almost half the cost of technology which is currently available. We’ve been amazed by the variety of industries who have approached us about integrating a UR3 into their production. The robot is extremely capable and easy to use…. When you combine this with the game changing price point, we can see the UR3 making a different for a large number of local manufacturers.” UR3 Key Features: • 6 axis, collaborative table-top robot • Weight: 11kg • Payload: 3kg • Reach: 500mm • 360 degree rotation on all wrist joints, infinite rotation on end joint • Repeatability: ±0.1 mm (±0,004 in) • 15 adjustable, advanced safety settings; force limit: […]
