#430094 Configuration and manipulation of soft ...

Traditional rigid-bodied robots are stiff, with few degrees of freedom, placing limits on many applications. Recently, more engineers are learning from the soft flexibility properties of living beings to advance bionic soft robotics. The main characteristics of soft robots are flexibility, deformability and energy-absorbtion. Continue reading

#430084 Solar Powered Garden Robot

Developed by Franklin Robotics, “Tertill” is a 100% solar-powered robot that lives in home gardens and weeds every day, rain or shine. The first wave of robots will be available this summer after Tertill’s crowdfunding campaign begins June 13. Upcoming Tertill models will be engineered with the ability to detect and repel pests, and relay info back to your smartphone as needed.

Tertill maintains your garden by using its artificial intelligence to determine the best times to sniff out new weeds. The bot regularly whacks newly sprouted weeds with its string trimmer and scrubs out emerging cotyledons with its wheels.

Tertill only trims plants under a certain height threshold, but if you have a short seedling that you don’t want whacked, Franklin Robotics offers protective collars that tell Tertill to steer clear. Other versions of collars double as slug repellents. A 3D-printable-design is available here. [http://www.franklinrobotics.com/slugtaze-download]

Solar-powered, chemical free organic gardening
Tertill’s mission is to eliminate the need for chemical weed treatments in the garden, while also offering a sustainable, 100% renewable solution for managing weeds.
Tertill takes advantage of the energy that it can gather from the sun in the most efficient way possible, and so it works hard to maximize the area that it covers each day. To keep weeds at bay it only needs to return to the same spot in the garden every few days. And since Tertill is fueled by the same solar energy that weeds are, it can patrol less often on cloudy days because the weeds are also less actively growing.

Future developments
Joe Jones, the developer of Tertill, and his team’s experience gardening (and struggling to get a good yield!) has shown them what a truly effective garden robot needs to provide. Beyond just weeding, future Tertill models will also include natural pest-repellent features to scare away rodents. Think of Tertill like a mobile scarecrow, except roughly the size of a frisbee.
These future Tertill models will also be able to collect data and analyze the soil quality, nutrients, and health, and send alerts back to the user with any important garden info.

Campaign Date
Franklin Robotics’ crowdsources fundraiser will be starting June 13. If you’d like to learn more, head to FranklinRobotics.com, and if you sign up for their newsletter, [http://www.franklinrobotics.com/slugtaze-download] you’ll receive a free download of Slugtaze, the 3D-printable slug-repellent collar.

#430020 How Robots Will Win Your Trust

What images come to mind when you think of robots?
The lifelike replicas of Blade Runner? A favorite video game character or perhaps Aldebaran and SoftBank's quirky robot named Pepper?
Although researchers have made astounding advances in robotics, robots have yet to approach their fictionalized counterparts in many areas. The greatest of these is their ability to gain our trust.
Trust is a foundation of our society. Whether implicit or explicit, our trust in one another forms the very basis of how we live our lives. But how will that change with advanced robots and AI?
It's naturally hard to trust something foreign and inhuman with important tasks. So how can we come to trust robots more, and does their perceived humanity play any part in our feelings?
Bonding Through Observation
As all trends point towards robots playing a large part in our future lives, scientists are obviously concerned with breaking down the barriers. The service industry, for instance, already uses customer-facing robots in a few select areas. As their placement becomes more mainstream, we must figure out how to introduce them to society.
A joint study between the Ars Electronica Futurelab, the University of Wurzburg and the University of Koblenz-Landau aimed to determine how to soften our emotions toward robots.
Participants interacted with a robot in one of three ways: in real life, virtual reality, and on a plain screen. During the five-minute test, Roboy the Robot helped to organize appointments, search the web, and find a birthday gift.
Data analysis showed that participants who watched the robot through the screen or through virtual reality perceived it as more real. They also indicated that they saw it as more human. Those who viewed the interactions through a screen indicated a higher humanness rating than those who used virtual reality.
The researchers pointed out that many people will encounter robots in the service industry in the coming years, quite possibly in hotels or hospitals. Most people today only experience robots through TV or science fiction, giving them a skewed perspective and leading them to mistrust a perfectly capable bot. Research is important to minimize skepticism and provide proven design choices for future models.
Extreme Environments and Robotic Dependence
There are certain locations and professions where using robots simply makes sense, such as spaceflight, deep-sea exploration, and hostile military zones. We'll inevitably make robots in these positions smarter and smarter, but will our level of trust rise to the occasion?
Consider remote control vehicles (RCVs) that are used for dangerous tasks, such as bomb disposal. Most of us don't trust RCVs like another human, despite the fact that they save many lives each year.
Reports show that people who work with RCVs on a regular basis form a strong emotional bond with their robotic partners. Some soldiers using explosive ordnance disposal (EOD) bots in Iraq and Afghanistan became extremely attached to their robots and insisted on working with the same units every time. They even became upset at the thought of using a new robot, rather than repairing their old one.
How Human Is Too Human?
The key to warming the public up to robots may be exposure. Humans build trust with robots through real life exposure, but as we build robots to look more like humans, will trust backslide? In the 1970s, Japanese roboticist Masahiro Mori proposed that people would only accept human-like robots to a point. As they begin to approach that point, people would withdraw. However, if the robots surpassed that point, people would trust them again.
This effect, dubbed the “uncanny valley,” refers mainly to the subtle discomfort produced when confronted with something that looks inhuman enough to break the illusion. A non-humanoid robot wouldn’t produce this feeling, as observers would never see it as a human form.
Surpassing the Uncanny Valley
Perhaps the best way to make humans more open to robots is to mirror more than appearance. The robots should have human mannerisms as well. During conversation, a robot should blink and hold eye contact—though not for too long. The average human blinks at a higher rate during conversation, and regularly moves their head and eyes to indicate thought processes and emotions.
When they speak, they should use the right tone of voice for their message. A sad message spoken with a happy tone pushes them into uncanny valley territory. Likewise, their sentences shouldn’t be completely direct. Most people use what’s called hedging—adding extra words like “you know,” “like,” and “um” to their sentences. These additions make a conversation feel much less contrived.
Finally, a robot needs less precise movement to look natural. When moving, they should have a short preparation phase—where they move back a bit—before going forward. Simply lurching in the intended direction is quite unnatural.
If they’re moving a limb, they should start with the bigger joints, and then move toward the smaller ones. Although it may seem easier to have the bot move whatever it uses for fingers, it’s an incredibly unhuman-like shortcut to take.
If your robot doesn’t have a face, make sure to compensate by having it express emotion in movement. Use small and slow movements to show sadness, jerky movements for fear and large movements for happiness. It may take a while to get them right, but the results will be worth the effort.
Humans and robots have a ways to go before complete trust is established. Through gradual exposure, we can increase our reliance on robots. Natural movements and actual day-to-day experience will increase trust. And the quicker we grow comfortable with robots, the better. After all, they’re poised to enter our workforce in unprecedented numbers.

#430007 ‘Harder, better, faster, ...

What if running the 26.2 miles of a marathon only felt like running 24.9 miles, or if you could improve your average running pace from 9:14 minutes/mile to 8:49 minutes/mile without weeks of training? Researchers at the Wyss Institute and John A. Paulson School of Engineering and Applied Sciences (SEAS) at Harvard University have demonstrated that a tethered soft exosuit can reduce the metabolic cost of running on a treadmill by 5.4% compared to not wearing the exosuit, bringing those dreams of high performance closer to reality. "Homo sapiens has evolved to become very good at distance running, but our results show that further improvements to this already extremely efficient system are possible," says corresponding author Philippe Malcolm, Ph.D., former Postdoctoral Research Fellow at the Wyss Institute and SEAS, and now Assistant Professor at the University of Nebraska, Omaha, where he continues to collaborate on this work. The study appears today in Science Robotics. Continue reading
