Humans physically interact with each other every day – from grabbing someone’s hand when they are about to spill their drink, to giving your friend a nudge to steer them in the right direction, physical interaction is an intuitive way to convey information about personal preferences and how to perform a task correctly.

Because of their high precision and speed, Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, welding and food packaging. Starting with the first version developed by Reymond Clavel for a chocolate factory to quickly place chocolate pralines in their packages, Delta robots use three individually controlled and lightweight arms that guide a platform to move fast and accurately in three directions. The platform is either used as a stage, similar to the ones being used in flight simulators, or coupled to a manipulating device that can, for example, grasp, move, and release objects in prescribed patterns. Over time, roboticists have designed smaller and smaller Delta robots for tasks in limited workspaces, yet shrinking them further to the millimeter scale with conventional manufacturing techniques and components has proven fruitless.

The first full-length mainstream music album co-written with the help of artificial intelligence (AI) was released on 12 January and experts believe that the science behind it could lead to a whole new style of music composition.

2017 was the year where indoor drone shows came into their own. Verity Studios’ Lucie drones alone completed more than 20,000 autonomous flights. A Synthetic Swarm of 99 Lucie micro drones started touring with Metallica (the tour is ongoing and was just announced the 5th highest grossing tour worldwide for 2017). Micro drones are now performing at Madison Square Garden as part of each New York Knicks home game — the first resident drone show in a full-scale arena setting. Since early 2017, a drone swarm has been performing weekly on a first cruise ship. And micro drones performed thousands of flights at Changi Airport Singapore as part of its 2017 Christmas show.

Deep neural networks (DNNs) have enabled great progress in a variety of application areas, including image processing, text analysis, and speech recognition. DNNs are also being incorporated as an important component in many cyber-physical systems. For instance, the vision system of a self-driving car can take advantage of DNNs to better recognize pedestrians, vehicles, and road signs. However, recent research has shown that DNNs are vulnerable to adversarial examples: Adding carefully crafted adversarial perturbations to the inputs can mislead the target DNN into mislabeling them during run time. Such adversarial examples raise security and safety concerns when applying DNNs in the real world. For example, adversarially perturbed inputs could mislead the perceptual systems of an autonomous vehicle into misclassifying road signs, with potentially catastrophic consequences.

Reinforcement Learning (RL) is a powerful technique capable of solving complex tasks such as locomotion, Atari games, racing games, and robotic manipulation tasks, all through training an agent to optimize behaviors over a reward function. There are many tasks, however, for which it is hard to design a reward function that is both easy to train and that yields the desired behavior once optimized.

In early December, 8000 machine learning researchers gathered in Long Beach for 2017’s Neural Information Processing Systems conference. In the margins of the conference, the Royal Society and Foreign and Commonwealth Office Science and Innovation Network brought together some of the leading figures in this community to explore how the advances in machine learning and AI that were being showcased at the conference could be harnessed in a way that supports broad societal benefits. This highlighted some emerging themes, at both the meeting and the wider conference, on the use of AI for social good.

DNA has often been compared to an instruction book that contains the information needed for a living organism to function, its genes made up of distinct sequences of the nucleotides A, G, C, and T echoing the way that words are composed of different arrangements of the letters of the alphabet. DNA, however, has several advantages over books as an information-carrying medium, one of which is especially profound: based on its nucleotide sequence alone, single-stranded DNA can self-assemble, or bind to complementary nucleotides to form a complete double-stranded helix, without human intervention. That would be like printing the instructions for making a book onto loose pieces of paper, putting them into a box with glue and cardboard, and watching them spontaneously come together to create a book with all the pages in the right order.

Well, this year’s videos are getting creative!

When you think of a treadmill, what comes to your mind?

Perhaps the images of a person burning calories, or maybe the treadmill fail videos online. But almost certainly not a miniature treadmill for insects, and particularly not as a tool for understanding fundamental biology and its applications to technology.

Millions of fans all over the world eagerly anticipated this week’s release of Star Wars: The Last Jedi, the eighth in the series. At last we will get some answers to questions that have been vexing us since 2015’s The Force Awakens.

Throughout the franchise, the core characters have been accompanied by a number of much-loved robots, including C-3PO, R2-D2 and more recently, BB-8 and K2-SO. While often fulfilling the role of wise-cracking sidekicks, these and other robots also play an integral role in events.

Democratization of Robots in Factories

In modern factories, human workers and robots are two major workforces. For safety concerns, the two are normally separated with robots confined in metal cages, which limits the productivity as well as the flexibility of production lines. In recent years, attention has been directed to remove the cages so that human workers and robots may collaborate to create a human-robot co-existing factory.

The Robot Launch global startup competition is over for 2017. We’ve seen startups from all over the world and all sorts of application areas – and we’d like to congratulate the overall winner Semio, and runners up Apellix and Mothership Aeronautics. All three startups met the judges criteria; to be an early stage platform technology in robotics or AI with great impact, large market potential and near term customer pipeline.

Three very different robotics startups have been battling it out over the last week to win the “Robohub Choice” award in our annual startup competition. One was social, one was medical and one was agricultural! Also, one was from the UK, one was from the Ukraine and one was from Canada. Although nine startups entered the voting, it was clear from the start that it was a three horse race – thanks to our Robohub readers and the social media efforts of the startups.
