This blogpost is a round up of the various sets of ethical principles of robotics and AI that have been proposed to date, ordered by date of first publication. The principles are presented here (in full or abridged) with notes and references but without commentary. If there are any (prominent) ones I’ve missed please let me know.
Asimov’s three laws of Robotics (1950)
I have included these to explicitly acknowledge, firstly, that Asimov undoubtedly established the principle that robots (and by extension AIs) should be governed by principles, and secondly that many subsequent principles have been drafted as a direct response. The three laws first appeared in Asimov’s short story Runaround [1]. This wikipedia article provides a very good account of the three laws and their many (fictional) extensions.
Murphy and Wood’s three laws of Responsible Robotics (2009)
These were proposed in Robin Murphy and David Wood’s paper Beyond Asimov: The Three Laws of Responsible Robotics [2].
EPSRC Principles of Robotics (2010)
These principles were drafted in 2010 and published online in 2011, but not formally published until 2017 [3] as part of a two-part special issue of Connection Science on the principles, edited by Tony Prescott & Michael Szollosy [4]. An accessible introduction to the EPSRC principles was published in New Scientist in 2011.
Future of Life Institute Asilomar principles for beneficial AI (Jan 2017)
I will not list all 23 principles but extract just a few to compare and contrast with the others listed here:
6. Safety: AI systems should be safe and secure throughout their operational lifetime, and verifiably so where applicable and feasible.
7. Failure Transparency: If an AI system causes harm, it should be possible to ascertain why.
8. Judicial Transparency: Any involvement by an autonomous system in judicial decision-making should provide a satisfactory explanation auditable by a competent human authority.
9. Responsibility: Designers and builders of advanced AI systems are stakeholders in the moral implications of their use, misuse, and actions, with a responsibility and opportunity to shape those implications.
10. Value Alignment: Highly autonomous AI systems should be designed so that their goals and behaviors can be assured to align with human values throughout their operation.
11. Human Values: AI systems should be designed and operated so as to be compatible with ideals of human dignity, rights, freedoms, and cultural diversity.
12. Personal Privacy: People should have the right to access, manage and control the data they generate, given AI systems’ power to analyze and utilize that data.
13. Liberty and Privacy: The application of AI to personal data must not unreasonably curtail people’s real or perceived liberty.
14. Shared Benefit: AI technologies should benefit and empower as many people as possible.
15. Shared Prosperity: The economic prosperity created by AI should be shared broadly, to benefit all of humanity.

The principles are expressed not as rules but instead as questions, or concerns, together with background and candidate recommendations.
A short article co-authored with IEEE general principles co-chair Mark Halverson Why Principles Matter explains the link between principles and standards, together with further commentary and references.
UNI Global Union Top 10 Principles for Ethical AI (Dec 2017)
Drafted by UNI Global Union‘s Future World of Work these 10 principles for Ethical AI (set out here with full commentary) “provide unions, shop stewards and workers with a set of concrete demands to the transparency, and application of AI”.
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.
Technologically, indoor drone show systems are challenging. They are among the most sophisticated automation systems in existence, with dozens of autonomous robotic aircraft operating in a safety-critical environment. Indoor drone shows require sophisticated, distributed system control and communications architectures to split up and recombine sensing and computation between aircraft and their off-board infrastructure. Core challenges are not unlike those found in modern systems for manned aviation (e.g., combining auto-pilots, GPS, and air traffic control) and in creating tomorrow’s smart cities (e.g., combining semi-autonomous cars with intelligent traffic lights in a city).
These technological challenges are compounded by another: At least for permanent show installations, these systems need to be operated by non-experts. Two years ago, in one of the first major indoor drone shows, a swarm of micro drones flew over the audience at TED 2016. That system was operated by Verity Studios’ expert engineers. Creating a system that is easy enough to use, and reliable enough, to be operated by show staff is a huge technical challenge of its own. All of Verity’s 2017 shows mentioned above were fully client-operated, which speaks to the maturity that Verity’s drone show system has achieved.
For my colleagues and me, it is these technological challenges, together with the visual impact of indoor drone shows, that makes these systems so much fun and hugely rewarding to work with.
Creative potential
Creatively, the capabilities of today’s indoor drone show systems barely scratch the surface of the technology’s potential. For centuries, show designers were restricted to static scenes. Curtains were required to hide scene changes from the audience, lest stage hands rushing to move set pieces destroy the magic created by a live show. The introduction of automation to seamlessly move backdrops and other stage elements, followed by the debut of automated lighting to smoothly pan and tilt traditional, stationary illumination were revolutionary.
Drones hold the potential for pushing automation further. The Lucies shown in the images above give a first inkling of the creative potential of flying lights that can be freely positioned in 3D space, appearing at will. Larger drones allow to extend that concept to nearly any object, including the creation of flying characters.
Safety
The most critical challenge for indoor drone show systems is safety. Indoor drone shows feature dozens of drones flying simultaneously and in tight formations, close to crowds of people, in a repeated fashion, in the high-pressure environment of a live show. For example, as part of the currently running New York Knicks drone show, 32 drones perform above 16 dancers, live in front of up to 20,000 people in New York’s Madison Square Garden arena, 44 times per season.
There are really only three ways to safely fly drones at live events.
The first way to achieve safety is the same that keeps commercial aviation safe: System redundancy. Using this approach, Verity Studios’ larger, Stage Flyer drones performed safely on Broadway, completing 398 shows and more than 7,000 autonomous flights, flying 8 times a week, in front of up to 2,000 people for a year, without safety nets. The Stage Flyer drones are designed around redundancy. At least two of each components are used (e.g., two batteries, two flight computers, and a duplicate of each sensor) or existing redundancies are exploited. For example, the Stage Flyer drones have only four propellers and motors, like any quadcopter. However, advanced algorithms that exploit the physics of flight allow these multi-rotor vehicles to fly with less than 4 propellers. The overall design allows these drones to continue to fly in spite of any individual component failure. For example, in one of the last Broadway shows, a Stage Flyer experienced a battery failure. The drone switched into its safety flight mode and landed, and the show continued with 7 instead of 8 drones. This approach to drone safety remains highly unusual — all drones available for purchase today have single points of failure.
The second approach to safety is physical separation. This is how safety is usually achieved for outdoor drone shows: Drones perform over a body of water or some roads are temporarily closed to create a large-enough area without people. For example, the Intel drone show at the Super Bowl was recorded far away from the NRG stadium. In fact, for the Super Bowl, safety went even a step further, also adding “temporal separation” to the physical separation (the drone show was actually pre-recorded days ahead of time, and viewers in the stadium and on TV were only shown a video recording). For indoor drone lightshows, physical separation can be achieved using safety nets.
The third approach to safely flying drones at live events is to make the drones so small that they have high inherent safety. Verity Studios’ Lucie micro drones weigh less than 1.8 ounces or 50 grams (including their flexible hull).
As the continuing string of safety incidents involving drones at live events attests, not everyone takes drone safety seriously. This is why my colleagues and I have worked with aviation experts and leading creatives to summarize best practices in an overview paper: Drone shows – Creative potential and best practices.
So, what’s in store for 2018? The appetite for indoor drone shows is huge, which is why Verity Studios is growing its team. And given the 2017 track record, there is a lot to look forward to — your favorite venue’s ceiling is the limit!
In this episode, Audrow Nash interviews Elliott Rouse, Assistant Professor at the University of Michigan, about an open-source prosthetic leg—that is a robotic knee and ankle. Rouse’s goal is to provide an inexpensive and capable platform for researchers to use so that they can work on prostheses without developing their own hardware, which is both time-consuming and expensive. Rouse discusses the design of the leg, the software interface, and the project’s timeline.
Elliott Rouse
Elliott Rouse is an Assistant Professor in the Mechanical Engineering Department at the University of Michigan, where he directs the Neurobionics Lab. The vision of his group is to discover the fundamental science that underlies human joint dynamics during locomotion and incorporate these discoveries in a new class of wearable robotic technologies. The Lab uses technical tools from mechanical and biomedical engineering applied to the complex challenges of human augmentation, physical medicine, rehabilitation and neuroscience. Dr. Rouse and his research have been featured at TED, on the Discovery Channel, CNN, National Public Radio, Wired Magazine UK, Business Insider, and Odyssey Magazine.

Here are the biggest Robocar stories of 2017.
By far, the biggest milestone of 2017 was the announcement by Waymo of their Phoenix Pilot which will feature cars with no safety driver behind the wheel, and the hints at making this pilot open to the public.
The huge deal is that Waymo’s lawyers and top executives signed off on the risk of running cars with no safety driver to take over in emergencies. There is still an employee in the back who can do an emergency shutdown but they can’t grab the traditional controls. A common mistake in coverage of robocars is to not understand that it’s “easy” to make a car that can do a demo, but vastly harder to make one that has this level of reliability. That Waymo is declaring this level puts them very, very far ahead of other teams.
The key sensor for the first several years of robocars will almost surely be LIDAR. At some point in the future, vision may get good enough but that date is quite uncertain. Cost is not a big issue for the first few years, safety is. So almost everybody is gearing up to use LIDAR, and many big companies and startups have announced new LIDAR sensors and lower prices.
News includes Quanergy (I am an advisor) going into production on a $250 8-line solid state unit, several other similar units in development from many companies, and several new technologies including 1.5 micron LIDARs from Luminar and Princeton Lightwave, 128 plane LIDARs from Velodyne and radical alternate technologies from Oryx in Israel and others. In addition, several big players have acquired LIDAR companies, indicating they feel it is an important competitive advantage.
At the same time, Waymo (which created its own special long range LIDAR) has been involved in a giant lawsuit against Uber, alleging that the Otto team appropriated Waymo secrets to build their own.
Here is some coverage I had on LIDAR deals.
In more recent news, today Velodyne cut the price of their 16 laser puck to $4,000. 16 planes is on the low side as a solo sensor but this price is quite reasonable for anybody building a taxi.
In 2016 NHTSA published 116 pages of robocar regulations. Under the new administration, they reversed this and published some surprisingly light handed replacements. States have also been promoting local operations, with Arizona coming out as one of the new winners.
There were many big acquisitions with huge numbers, including NuTonomy (by Delphi) but the biggest ever deal was the $16B purchase of MobilEye by Intel.
MobilEye of course has a large business in the ADAS world but Intel wants the self-driving car part and paid a multi billion dollar premium for it.
It’s not a real order quite yet but this intent to buy $1B of cars to put Uber software on shows how serious things are getting, and should remove from people’s minds the idea that Uber doesn’t intend to own a fleet.
They aren’t here yet, but there’s a lot more action on Flying Cars, or in particular, multirotor drone-style vehicles able to carry a person. It looks like these are going to happen, and they are the other big change in the works for personal transportation. It remains uncertain if society will tolerate noisy helicopters filling the skies over our cities, but they certainly will be used for police, ambulance, fire and other such purposes, as well as over water and out in the country.
A little more uncertain is the Hyperloop. While the science seems to work, the real question is one of engineering and cost. Can you actually do evacuated tubes reliably and at a cost that works?
Twenty-one different startups were funded in December cumulatively raising $430 million, down from the $782 million in November. Three didn’t report the amount of their funding. Only three were over $50 million of which one was a Chinese startup. Three acquisitions were reported during the month including two takeovers of Western robotics companies by Chinese ones. Nothing new on the IPO front.
In this episode of Robots in Depth, Per Sjöborg speaks with Daniel Lofaro, Assistant Professor at George Mason University specialising in humanoid robots.
Daniel talks about making humans and robots collaborate through co-robotics, and the need for lower-cost systems and better AI. He also mentions that robotics needs a “killer app”, something that makes it compelling enough for the customer to take the step of welcoming a robot into the business or home. Finally, Daniel discusses creating an ecosystem of robots and apps, and how competitions can help do this.
