Swiss university developing mobile robot that learns on the job

by Leave a Comment

A team from the Autonomous Systems Lab at the public research university ETH Zurich in Switzerland is creating robots and intelligent systems that are able to learn on the job. (See video below.)

The team’s machine – which consists of a robotic arm mounted on a mobile platform – can “autonomously operate in complex and diverse environments”, says an article on Clearpath Robotics’ website.

Using a Clearpath Ridgeback as a base and equipped with a Franka Emika Panda manipulator arm (called RoyalPanda, that is Ridgeback + Panda), the team is experimenting with a series of different scenarios to develop best practices of how a robot could “learn”.

Showing robots how to drive a car… in just a few easy lessons

by Leave a Comment

USC researchers have developed a method that could allow robots to learn new tasks, like setting a table or driving a car, from observing a small number of demonstrations.

Imagine if robots could learn from watching demonstrations: you could show a domestic robot how to do routine chores or set a dinner table. In the workplace, you could train robots like new employees, showing them how to perform many duties. On the road, your self-driving car could learn how to drive safely by watching you drive around your neighborhood.

Making progress on that vision, USC researchers have designed a system that lets robots autonomously learn complicated tasks from a very small number of demonstrations – even imperfect ones. The paper, titled Learning from Demonstrations Using Signal Temporal Logic, was presented at the Conference on Robot Learning (CoRL).

IBM launches new industrial chemistry robot to enable lab automation

by Leave a Comment

IBM has launched a new industrial chemistry lab robot called RoboRXN, describing it as “the first remotely accessible, autonomous chemical laboratory”. (See video below.)

The computing giant says the RXN machine is “revolutionizing industrial chemistry, by transforming it into a high tech business”.

RXN uses a combination of artificial intelligence, automation and cloud computing to relieve the chemist from tedious repetitive tasks, allowing more time and space for design and innovation. [Read more…] about IBM launches new industrial chemistry robot to enable lab automation

CMU researchers train autonomous drones using cross-modal simulated data

by Leave a Comment

To fly autonomously, drones need to understand what they perceive in the environment and make decisions based on that information. (See video below.)

A novel method developed by Carnegie Mellon University researchers allows drones to learn perception and action separately.

The two-stage approach overcomes the “simulation-to-reality gap”, and creates a way to safely deploy drones trained entirely on simulated data into real-world course navigation. [Read more…] about CMU researchers train autonomous drones using cross-modal simulated data

Heraeus and Aachen University develop ‘fastest-ever’ artificial synapses

by Leave a Comment

The boffins say that the secret is ‘foreign atoms in the oxide layer’ which have so far gone unnoticed by experts

Scientists and researchers from the materials science-oriented technology group Heraeus and the Jülich Aachen Research Alliance have developed what they describe as “artificial synapses” similar to the ones found in the human brain.

The collective of brainboxes say that their discovery could be useful in the development of branches of artificial intelligence, such as machine learning and deep learning.

The boffins discovered how the switching properties of artificial synapses can be specifically influenced. [Read more…] about Heraeus and Aachen University develop ‘fastest-ever’ artificial synapses

Scientists develop ‘flexoskeletons’ that cost a dollar to 3D print

by Leave a Comment

Engineers at the University of California San Diego have developed a new method that doesn’t require any special equipment and works in just minutes to create soft, flexible, 3D-printed robots. (See video below.)

The innovation comes from rethinking the way soft robots are built: instead of figuring out how to add soft materials to a rigid robot body, the UC San Diego researchers started with a soft body and added rigid features to key components.

The structures were inspired by insect exoskeletons, which have both soft and rigid parts – the researchers called their creations “flexoskeletons”. [Read more…] about Scientists develop ‘flexoskeletons’ that cost a dollar to 3D print

Columbia engineers develop ‘tactile robot finger with no blind spots’

by Leave a Comment

Researchers at Columbia Engineering say they have developed a new type of robotic finger with a sense of touch. Their finger can localize touch with very high precision – less than 1 mm – over a large, multicurved surface, much like its human counterpart. (See video below.)

Matei Ciocarlie, associate professor in the departments of mechanical engineering and computer science, says: “There has long been a gap between standalone tactile sensors and fully integrated tactile fingers–tactile sensing is still far from ubiquitous in robotic manipulation.”

Ciocarlie led this work in collaboration with Electrical Engineering Professor Ioannis Kymissis. [Read more…] about Columbia engineers develop ‘tactile robot finger with no blind spots’

Iowa scientists create nanoscale sensors to ‘better see how high pressure affects materials’

by Leave a Comment

Scientists at Iowa State University have developed new nanoscale technology to image and measure more of the stresses and strains on materials under high pressures.

As the researchers reported in the journal Science, that matters because, “Pressure alters the physical, chemical and electronic properties of matter.”

Understanding those changes could lead to new materials or new phases of matter for use in all kinds of technologies and applications, said Valery Levitas, a paper co-author and Anson Marston Distinguished Professor in Engineering at Iowa State University, the Vance Coffman Faculty Chair and professor in aerospace engineering.

Automation increases productivity in materials science by 384 times, say researchers

by Leave a Comment

An automated method of conducting materials science research can increase productivity by 384 times when compared to a human, according to researchers. 

The robot-plus-software system also makes it easier for people who are not expert researchers or scientists to create new materials.

A Rutgers-led team of engineers has developed an automated way to produce polymers, making it much easier to create advanced materials aimed at improving human health. [Read more…] about Automation increases productivity in materials science by 384 times, say researchers

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

by

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
