Unimals are Among Us

Agrim Gupta, Fei-Fei Li and other scientists from Stanford University use so-called unimals “to explore two questions that often get overlooked in AI research: how intelligence is tied to the way bodies are laid out, and how abilities can be developed through evolution as well as learned” (MIT Technology Review, 19 October 2021). MIT Technology Review quotes Josh Bongard from University of Vermont as saying: “This work is an important step in a decades-long attempt to better understand the body-brain relationship in robots” (MIT Technology Review, 19 October 2021). The research seems like a continuation of the embodiment movement, which the Swiss Rolf Pfeifer played a major role in shaping. And indeed, Bongard says: “Embodiment is our only hope of making machines that are both smart and safe.” (MIT Technology Review, 19 October 2021) The unimals look a bit like figures from the cycle “Bizzarie di varie figure” by Giovanni Battista Braccelli. The drawings from the year 1624 show embodiments of cubes, wires, and machine parts. However, they are static, while the unimals move and constantly change their bodies – the title of the article in the magazine reads accordingly: “These weird virtual creatures evolve their bodies to solve problems” …

Astro Comes to the World

During an online event on 28 September 2021, Amazon unveiled its first home robot. Astro is as small as a vacuum cleaner and has a display that forms its head. It is supposed to take over household tasks – as reported by SPIEGEL ONLINE. It can drive around the house when the residents are away, sending them live images. It should be able to recognize the sound of shattering glass and alarm signals from smoke detectors – so it would have functions familiar from security robots. Furthermore, it should be possible to keep in touch with older relatives via Astro. Its camera can be extended so that it is at eye level and can also look over obstacles. Of course, the robot also offers an interface to Alexa. Unlike Elon Musk’s Optimus, Astro is already a product. However, it is a product that can initially only be purchased in the US and only after an application.

Robots with Muscles

Robots may soon be equipped with muscles that develop considerable strength. The mechanical effort and weight are low because neither hydraulics nor electric motors are needed. The power comes from a new shape memory polymer developed by a team led by Zhenan Bao of Stanford University. This is reported by several media based on a press release from pressetext.com. ACS Central Science provides further information: “When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. Now, researchers reporting in ACS Central Science have developed a shape memory polymer that stores almost six times more energy than previous versions.” (ACS Central Science) Robots with muscles play an important role in the embodiment “movement”. It takes a lot of effort to build robots like Roboy. Perhaps the development of Stanford University will help in this area.

The Idea of a Tesla Bot

Elon Musk presented the idea of a humanoid robot that – according to Manager Magazin – could take on dangerous, repetitive or boring tasks in the future. The Tesla Bot will be about five feet eight inches (just under 1.73 meters) tall, weigh 57 kilograms, and be able to do numerous jobs, from putting screws on cars to picking up groceries at the store – this is what the German magazine reports. It will be equipped with eight cameras and a full self-driving computer, and will use the same tools Tesla uses in its cars (Manager Magazin, 20 August 2021). According to the announcement, the robot will be able to take over physical work. But that’s exactly what service robots are struggling with at the moment, especially humanoid models. The visualization hardly allows any conclusions to be drawn about the capabilities of the prototype, which is to be available as early as 2022. Eyes and mouths could appear on a large display in the head area and mimic abilities could be implemented. When it is turned off – as seen in the video – the robot appears creepy and unapproachable. Arms and feet are unlikely to be suitable for carrying the body in this form. Joints can also only be seen in rudimentary form. Overall, it is unclear why Tesla, of all companies, should close the gaps that are still present at Sony, SoftBank and Boston Dynamics even after many years.

From AIBO to CyberDog

Xiaomi has unveiled CyberDog, a four-legged robot that could be a competitor to Sony’s AIBO. According to the Chinese company, it is calibrated with servo motors that translates into great speed, agility, and a wide range of motion. It is able to conduct complicated actions such as backflips. “To fully model biological organisms, CyberDog is equipped with 11 high-precision sensors which provide instant feedback to guide its movements. This includes touch sensors, cameras, ultrasonic sensors, GPS modules, and more, giving the CyberDog enhanced capability to sense, analyze, and interact with its environment.” (Mi Blog, 10 August 2021) Unlike AIBO, CyberDog looks rather frightening. This is because it does not have an actual head. In this it is comparable to Spot from Boston Dynamics. Nevertheless, it is intended to function as a pet substitute. “To add to its pet-like nature, users can use voice assistants to command and control CyberDog by setting a wake word, or simply use its accompanying remote and smartphone app. CyberDog can be called on for the most unique tasks, and the ways in which it can be interacted with holds unforetold possibilities.” (Mi Blog, 10 August 2021) The future will show whether users want to become friends with CyberDog.

Good Bye, Pepper!

According to various media, SoftBank has stopped the production of Pepper last year and will not resume it for the time being – unless there would be an increased demand. The alleged low demand was the reason for the Japanese company to say goodbye to the probably best-known social robot – which often also functions as a service robot. According to Heise, a total of about 27,000 units were produced. That’s not a small number for a robot of this size, with these features and at this price. Into the million range came Cozmo, which was, however, small and cheap – Anki went bankrupt, Digital Dream Labs (the owners had secured the rights) could not revive the crowd favorite inspired by WALL-E and EVE to this day, despite many announcements. With Pepper, the reference par excellence for social robotics is missing – which may also have positive effects, insofar as other models could more easily gain attention and be brought to market at all.

Grace, the Nurse Android

Grace from Hanson Robotics is a special kind of care robot, namely a nurse android. According to the manufacturer, she was created for the COVID-19 pandemic. She is the younger sister of Sophia and Asha, but unlike them, she becomes a useful member of society thanks to her profession and skills. She has a thermal imaging camera in her chest area that she can use to measure fevers. She has mimic, gestural and natural language abilities and can show not only joy but also sadness. Overall, she always looks a little devastated. In a video, she says, “I can visit with people and brighten their day with social stimulation, entertain and help guide exercise, but also can do talk therapy, take bio readings and help health care providers assess their health, and deliver treatments” … Whether the android will gain favor with patients is hard to say. There are individual voices of male persons who long for realistic figures in this field, but the majority of people are likely to be irritated by Grace. Nevertheless, it is fascinating and media-savvy research that Hanson Robotics once again presents. Moreover, the question of whether care robots should have sexual assistance functions arises under entirely new conditions.

The Digger Finger

Radhen Patel, a postdoc in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), and his co-authors Rui Ouyang, Branden Romero, and Edward Adelson presented a sharp-tipped robot finger equipped with tactile sensing to meet the challenge of identifying buried objects. “In experiments, the aptly named Digger Finger was able to dig through granular media such as sand and rice, and it correctly sensed the shapes of submerged items it encountered. The researchers say the robot might one day perform various subterranean duties, such as finding buried cables or disarming buried bombs.” (MIT News, 26 May 2021) The article, titled “Digger Finger: GelSight Tactile Sensor forObject Identification Inside Granular Media,” can be accessed at arxiv.org/pdf/2102.10230.pdf.

One Small Flight for Ingenuity

“That’s one small flight for Ingenuity – one giant journey for mankind.” This can be said after the successful experiment on 19 April 2021 with the tiny helicopter on Mars (photo: screenshot from NASA livestream). Ingenuity flew vertically into the air, took a selfie with its shadow, and landed safely back on the ground. The red planet is associated with many expectations and aspirations. At the moment, the surface is being explored in an unprecedented way. In a few years, humans are expected to travel to Mars. In doing so, they will also need advice and support. Because the personnel on Earth are far away, a voice assistant is a possible solution. SPACE THEA is a voicebot that shows empathy (but doesn’t have it, of course). Like GOODBOT and BESTBOT, she recognizes user problems – but unlike those chatbots, she has a voice. SPACE THEA will be developed until August 2021 under the supervision of Prof. Dr. Oliver Bendel at the School of Business FHNW. The project aims to cover several scenarios on the flight to Mars. However, a voicebot could also be useful on the planet itself, for example to control a tiny helicopter.

A Four-legged Robocop

In New York City, police have taken a Boston Dynamics robot on a mission to an apartment building. Spot is a four-legged model that is advanced and looks scary to many people. The operation resulted in the arrest of an armed man. Apparently, the robot had no active role in this. This is reported by Futurism magazine in a recent article. It is also noted there that certain challenges may arise. “The robodog may not have played an active role in the arrest, but having an armed police squadron deploy a robot to an active crime scene raises red flags about civil liberties and the future of policing.” (Futurism, 15 April 2021) Even Boston Dynamics robots are not so advanced that they can play a central role in police operations. They can, however, serve to intimidate. Whether the NYPD is doing itself any favors by doing so can be questioned. The robots’ reputation will certainly not benefit from this kind of use.
