Subsea valve actuator ‘reduces energy consumption by up to 75 per cent’, says Rexroth

by

Launched less than a year ago, Bosch Rexroth’s innovative Subsea Valve Actuator (SVA) – an entirely new concept for underwater actuators which offers SIL3 safety levels and up to 75 per cent lower energy consumption – has been granted a Mechanical Engineering Design Award.

The SVA was developed to help address some of the challenges and shortcomings associated with either purely electromechanical or electrohydraulic actuator technology used on the sea floor for oil and gas exploration and production systems.

Until now, underwater actuators required large, central hydraulic power units above water. Designed to supply the actuators with fluid, the fluid-lines themselves can be miles long. [Read more…] about Subsea valve actuator ‘reduces energy consumption by up to 75 per cent’, says Rexroth

Genesis Robotics accelerates development of prototypes based on its ‘revolutionary’ LiveDrive actuator

Well-funded startup Genesis Robotics has accelerated the development of a range of products based on its “ground-breaking” technology, which the company claims will transform the entire industry. 

All of the new products Genesis has developed are based on something it calls LiveDrive, an actuator system which uses a gear with no teeth, invented by the company itself.

Making a gear work without teeth sounds impossible – how does it move connected parts without teeth? Imagine a gear on a bicycle without teeth and you’ll get the picture.  [Read more…] about Genesis Robotics accelerates development of prototypes based on its ‘revolutionary’ LiveDrive actuator

Spinea launches new servo actuator for precision motion

Spinea has launched its new DS 095 DriveSpin servo actuator motor for precision control.

Recently announced by Spinea and available in the UK from Heason Technology, the DriveSpin DS 095 series integrates the industry leading TwinSpin high-load capacity trochoidal gear unit and a powerful AC servomotor with servo feedback for a cutting-edge rotary actuator solution for precision motion applications.

The inline (non-hollowshaft) design of the DS 095 fulfils the gap between the DS 70 and DS 100 models to provide a rated torque of up to 85 Nm and maximum lost motion and hysteresis values of less than one arc-min.  [Read more…] about Spinea launches new servo actuator for precision motion

Genesis Robotics launches revolutionary new actuator for robots that eliminates the need for gears

Company claims its LiveDrive actuator system offers “unparalleled performance”, and will replace traditional gears – and change the global robotics market forever

A well-funded startup called Genesis Robotics claims it has developed “breakthrough” technology which is set to change the global robotics market. 

The vast majority of robots today use gears in their actuators and other parts. Gears – as an invention – are thousands of years old and have served industry and humanity well and will continue to do so, but Genesis claims it has developed a better solution, which it calls LiveDrive.

Genesis says traditional gears are slow, expensive and the way their teeth work creates something called “backlash” – like a rebound or bounceback as the teeth from different gears interact or collide, as well as friction. This inevitably leads to waste of energy.

Genesis’ LiveDrive system does not use teeth, so doesn’t have bounceback and reduces that type of friction. The company says its actuator is also less expensive to begin with and could lead to longer-term savings because it’s more energy-efficient – so its total cost of ownership is much lower.  [Read more…] about Genesis Robotics launches revolutionary new actuator for robots that eliminates the need for gears

The wheel robot: intelligent modular actuator concept

Wheel robots

The wheel robots are for the larger part derived from the Mars rovers, which have actuators integrated into the wheels to help with the movement on the rugged grounds in space. This is made possible with the help of 12 volt linear actuators.

There is some elemental aspects of robotics that are involved in the setup. For there to be synchronous movement on a ground that is not evenly leveled, there is need for each of the units to have its own local control unit.

The local control units are then connected to the central control unit to make sure that they all are moving in the same direction, despite the fact that the wheels they control are experiencing variance in travel and elevation.  [Read more…] about The wheel robot: intelligent modular actuator concept
