Robots: Androids, Human Presence and the Uncanny Valley

This episode covers android science and human-robot interactions with expert Hiroshi Ishiguro from Osaka. After the interview we feature the last installment of Jack Graham's Selkies story, as well as a poll on the future of Androids.

Hiroshi Ishiguro

Hiroshi Ishiguro is Professor of the Department of Adaptive Machine Systems, and the group leader of the Intelligent Robotics Laboratory at Osaka University.

If you've ever seen an Android robot in the news, it probably came out of the Intelligent Robotics Laboratory. Starting from the robotic replicate of his then 5 year old daughter, Prof. Ishiguro then went on to model a female android after Ayako Fujii, the NHK news announcer. Finally, his latest robot Geminoid, which is a close copy of himself, is able to replace its creator in lectures and interviews.

His robots are highly actuated to give them human like facial expressions and reflexes. However, because the AI needed to interact in a human-like manner is not always advanced enough, Prof. Ishiguro has been looking to partially teleoperate his robots. Another approach investigated is to make his robots autonomous by having them perceive and react to their world thanks to networks of cameras and microphones.

Using these robots as a tool, Prof. Ishiguro has been exploring the field of Android Science, which looks at both the appearance and behavior of humanoid robots and their impact on human robot interactions. In particular, he is looking to verify the existence of the uncanny valley and to explore how to make androids which sufficiently resemble humans to be likable. On the more philosophical side, his androids open the door to understanding what human presence really means.

Survey

What is your take on androids? Will androids ever become indistinguishable from humans, both in looks and behaviour? Will they become unrecognizable like the Cylons from Battlestar Galactica, or remain awkward like Data from Star Trek? Take the poll on the Robots forum!

Selkies

In this last installment of the Jack Graham's Selkies story Mangan sets his Selkies free with a new schooling algorithm in a sea full of sharks. Will this new generation of robotic swimmers escape the jaws of the sharks? Tune in to find out...

Robots: Jumping and Crawling in Millirobots

This episode concentrates on how to scale down robots to the size of our creepy crawly friends, insects. Sarah Bergbreiter tells us about the micromachining techniques required to build jumping robots at this small scale and the applications in sensor networks. Aaron Hoover then talks about his 6-legged crawling robot that is slowly approaching the cockroach in size and locomotion capability.

Sarah Bergbreiter

Sarah Bergbreiter is Assistant Professor of Mechanical Engineering at the University of Maryland where she directs the Micro Robotics Lab.

With her vision of mobile sensor networks composed of large numbers of autonomous robots, Bergbreiter first started designing the CotsBots, built entirely from commercial off-the-shelf components. She then went to micro-sized robots which could be used in a non-invasive manner in their deploying environment. As a first step in her endeavor she contributed to Seth Hollar and Anita Flynn's walking microrobot and then went on to her own tiny jumping robots to achieve better mobility. To enable jumping, she demonstrated the quick release of a mechanical leg based on a silicon micro rubber band (see video here).

Finally, to avoid spending hours in a clean room, Bergbreiter is looking to develop fabrication techniques for the fast prototyping of novel robots, in particular with respect to challenges in scaling down robotic components for energy storage, actuation, power, sensing and control.

Aaron Hoover

Aaron Hoover is a research assistant in Prof. Ron Fearing's lab at the University of California at Berkeley. His expertise lies in the use of novel manufacturing techniques based on smart composites, flexure joints and folding structures. Hoover's efforts to mimic complex biological systems such as beetles that can run over a myriad of surfaces has culminated in the 2.4g RoACH hexapod robot. The RoACH is capable of crawling autonomously at 1 body length per second and can last for almost 10 minutes on a single charge. Check out a video of the RoACH in action!

Selkies

In the third quarter of the science fiction story "Selkies" by author Jack Graham, we meet researcher Sylvia Ochoa from the UN Marine Fisheries and follow Mangan in his endeavor to shark-proof his robot-seals. Don't miss his other SciFi stories straight out of Cambridge MA on lonesomerobot.com, such as "arm" and "posthuman playground".

Robots: Warehouse Robots

In this episode we sit down with Raffaello D'Andrea, professor at the Swiss Federal Institute of Technology in Zurich (ETHZ) and founding member of Kiva Systems, to speak about their Kiva robotic warehouse system. We then continue with the second quarter of Jack Graham's sci-fi story, Selkies.

Raffaello D'Andrea

Prof. Raffaello D'Andrea is an expert in multi-robot systems, leading the Cornell Robot Soccer Team to four world championship wins at the international RoboCup competition. After ten years of assistant and then associate professorship at Cornell University, D'Andrea crossed the lake to take a position as full professor at ETHZ in Zurich.

Not satisfied with research however, D'Andrea has applied his knowledge to industry, and is co-founder and Engineering Fellow at Kiva Systems. He describes for us Kiva's Mobile Fulfillment System, a revolutionary robotic warehouse concept that uses hundreds of mobile robots to fetch items for workers, increasing efficiency and looking really cool in the process!



Besides creating robots for research or industry, D'Andrea is also a creator of dynamic sculpture. His robotic art has appeared at various international venues, including the National Gallery of Canada and the Venice Biennale. In an attempt to spread his passion and get students thinking about robotics outside the laboratory, D'Andrea is teaching a project course at ETHZ in which students design and build a dynamic sculpture purely for public display.



Selkies

Science Fiction author, Jack Graham from lonesomerobot.com treats us to the second quarter of his story "Selkies". As a flash back, the first episode introduced roboticist Mangan, his sea-lion pet Cato and the team of seal-like robots called selkies which work in the depths of the ocean to clean up waste. In this episode, Jack, further pushes us into the ambiance of his futuristic world where unexpected visits and disappearing selkies create the intrigue.

Robots: Swarming Autonomous Underwater Vehicles

In this show we dive into the world of autonomous underwater vehicles (AUVs) with an emphasis on the challenges when having to localize and communicate in the deep blue. While Navinda Kottege at the Australian National University has been looking at how swarms of small Serafina AUVs can determine their range, bearing and posture with respect to neighboring robots, Marc Sherman from Teledyne RD Instruments tells us how his Doppler Velocity Log systems are used to provide positioning for slightly larger beasts.

For a more futuristic view on underwater swarms, we present the first episode of our Science Fiction Special written by Jack Graham in Cambridge, MA. The "Selkies" will be following us over the next four episodes so don't miss today's debut.

Finally, if you're curious about last week's Uncertain Roomba Competition, check our forum for the winner and the actual solution.

Navinda Kottege

Navinda Kottege is a research assistant at the Australian National University, and has spent the last few years working on an underwater localisation system for swarms of AUVs, in particular the Serafina Robot.

Navigating and communicating with neighbors underwater is a difficult task (unless you're a fish), since there is no GPS, radio communication is very limited, and vision is essentially useless. Kottege explains the challenges they had to overcome to build swarms of Serafina robots, and some of the possible applications of their swarm once they're roaming our oceans.

Also, don't miss a past interview on Talking Robots with Uwe Zimmer who is at the head of the Serafina project.

Marc Sherman

Marc Sherman is the sales manager for navigation products at Teledyne RD Instruments, a big league supplier of Acoustic Doppler Current Profilers (ADCPs), Waves Measurement Products, Doppler Velocity Logs (DVLs), and Flow Measurement Products for offshore vehicles. He presents the DVLs used for underwater localization of anything from divers to ships, with an emphasis on the smaller Explorer system. While not yet small enough to suit Kottege's Sarafina AUVs, there is a clear interest to scale down, for shallow water applications in security and defense.

Selkies

Our special guest, science fiction writer Jack Graham in Cambridge MA, tells us about the "Selkies", seal-like robots which in a world of waste, strive to clean up the oceans. With a unique view on robotics and the world, he's been writing away on lonesomerobot.com with stories such as "arm" and "posthuman playground". The future will tell, how SciFi will continue to nourish engineers and vice-versa.

Robots: An Uncertain Revolution

In this episode we dive into the revolution brought on by the field of probabilistic robotics with Claudio Mattiussi who is Senior Researcher at the Laboratory of Intelligent Systems in Lausanne, Switzerland. We then launch a most "uncertain" competition to see how our listeners are able to cope with uncertainty in estimating the cleaning capabilities of our Roomba robot.

Claudio Mattiussi

As a Senior Researcher at the Laboratory of Intelligent Systems at the EPFL in Lausanne Switzerland, Claudio Mattiussi has been looking into the world of evolutionary computation, neural networks and machine learning applied to tasks such as reverse engineering gene regulatory networks, synthesizing neural networks, and designing electronic circuits. Thanks to his experience with real-world applications and years in industry, Mattiussi has become aware of the need to deal with uncertainty, which is present in most environments and living beings. As a solution, he presents the probabilistic or Bayesian approach to perceiving the world, with a touch of history, philosophy and projection. Rather than being against good old fashion artificial intelligence (GOFAI), or Brooks' Behavior Based approach, he proposes the "uncertain" revolution using the probabilistic paradigm as being a compromise for the future.

Finally, he discusses how the probabilities can be used to make decisions on robot behavior using neural structures and evolutionary techniques.

Uncertain Contest

For a detailed view on some of the subjects presented in this show, win the new book on "Bio-Inspired Artificial Intelligence: Theories, Methods, and Technologies" written by Dario Floreano and Claudio Mattiussi, out on the 30th of September 2008.

To make you apply your own probabilistic approaches to a concrete problem, we'll be asking you to guess (or compute) the percentage of dirt collected by a Roomba robot in its own "uncertain" environment. We're waiting for your vote by Wednesday, September 24th at 9AM GMT.

All the details for the competition can be found on our forum.
