Researchers develop robot fingertips for grasping and releasing objects in dry and wet conditions

A team of researchers at Kanazawa University has developed a robot control system – or fingertips – for grasping and releasing objects in dry and wet conditions.

The researchers say that the study was able to verify that “object grasping by soft surface fluid fingertips with high friction was controllable by applying a suitable lubricant”.

However, they added that it was necessary to do more experiments under various conditions in order to apply the current controlling technology to manufacturing environments. [Read more…] about Researchers develop robot fingertips for grasping and releasing objects in dry and wet conditions

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

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

Six innovative companies nominated for grand prize at microtechnology trade show

Six innovative companies have been nominated for the grand prize at the microtechnology trade show EPHJ, the leading showcase for watchmaking, jewellery, and micro- and medical technologies sectors.

The jury of experts of the 2019 EPHJ-EPMT-SMT Trade Fair has selected six highly innovative projects for the Exhibitors’ Grand Prix to be voted on by the exhibitors to select and announce the winner at the show, which will take place in Geneva, Switzerland from 18-21 June.

Levitation of machines, the green properties of supercritical CO2, machine learning algorithms, new hope for the 16 million people suffering from retinal vein occlusion, a machine that is mightier than a spark and a new fine-layer treatment process are just a few of the spectacular innovations proposed by the six nominees for the 2019 Exhibitors’ Grand Prix selected by the Jury for the EPHJ-EPMT-SMT Trade Show.

Water-based reconfigurable robot could offer new solutions to underground pipe network inspection

Researchers at the University of Sheffield have created an aquatic robot which could be used to inspect otherwise inaccessible pipe networks to deal with blockages.

The researchers revealed their findings later this week at the International Conference on Robotics and Automation (ICRA 2016) – the world’s largest gathering in robotics, held this year in Stockholm, Sweden.

The study looks at a set of robotic modules that, similar to Lego, can be assembled into robots of arbitrary shape. This allows robots to be customised to meet the changing demands of their task.
