Usability for All

Technology can provide huge benefits when we take care to use it wisely. Considering usability is extremely important and we need to keep focusing on improving usability. This video shows an interesting application by Abhishek Singh’s to increase the usability of “smart speakers.” His app runs on a tablet allow a user to use American Sign Language to interact with Alexa (it displays Alexa’s responses in text on the table).

Growing Citrus in the Snow

The system uses the constant ground temperature 2.5 meters (8 feet) below ground to heat a greenhouse. The underground-temperature on his farm is 11 degrees (52 degrees Fahrenheit). Other nearby areas range from 9 to 17 degrees (17 is near a hot spring).

Just circulating air through 64 meters (210 feet) of tubing buried 2.5 meters underground is enough to allow citrus and other plants to thrive. Selling at local farmer’s markets brings in a very high profit for farmers that can grow and sell locally.

Using the power of the sun to grow and the constant ground temperature to keep the air warm enough creates an opportunity to grow all year round. The same principles can be used to cool down indoor temperatures in very hot locations near the equator.

Due to the controlled environment growing organically is easy so that further increases the payoff for this type of farming.

The cost of the system can be as low as $25,000 if you have access to a backhoe to dig the trenches for the air pipes and can do much of the labor yourself. That is the cost of just the heating systems for a conventional greenhouse.

I really like this type of intersection of engineering and business (as well as environment and health benefits – providing healthy local food) that creates value to society by using our knowledge effectively.

Animations of Motor Proteins Moving Material Inside Cells

Very cool. This next video gives a bit more information on how these amazing parts of our cells move material around inside or cells.

This stuff is so interesting. I wish this type of interesting material and informative animations was what my biology education was like in k-12 instead of the boring stuff my classes were instead. I hope students today have better science classes than I did.

It is amazing how such mechanisms evolved to “walk” along transportation microtubules inside our cells.

Toyota’s Newest Humanoid Partner Robot

T-HR3 reflects Toyota’s broad-based exploration of how advanced technologies can help to meet people’s unique mobility needs. T-HR3 represents an evolution from previous generation instrument-playing humanoid robots, which were created to test the precise positioning of joints and pre-programmed movements, to a platform with capabilities that can safely assist humans in a variety of settings, such as the home, medical facilities, construction sites, disaster-stricken areas and even outer space.

“The Partner Robot team members are committed to using the technology in T-HR3 to develop friendly and helpful robots that coexist with humans and assist them in their daily lives. Looking ahead, the core technologies developed for this platform will help inform and advance future development of robots to provide ever-better mobility for all,” said Akifumi Tamaoki, General Manager, Partner Robot Division.

T-HR3 is controlled from a Master Maneuvering System that allows the entire body of the robot to be operated instinctively with wearable controls that map hand, arm and foot movements to the robot, and a head-mounted display that allows the user to see from the robot’s perspective. The system’s master arms give the operator full range of motion of the robot’s corresponding joints and the master foot allows the operator to walk in place in the chair to move the robot forward or laterally. The Self-interference Prevention Technology embedded in T-HR3 operates automatically to ensure the robot and user do not disrupt each other’s movements.

Onboard T-HR3 and the Master Maneuvering System, motors, reduction gears and torque sensors (collectively called Torque Servo Modules) are connected to each joint. These modules communicate the operator’s movements directly to T-HR3’s 29 body parts and the Master Maneuvering System’s 16 master control systems for a smooth, synchronized user experience.

Wiring a Thermometer to Your Van to Turn on AC as Needed as You Sleep

You may well not be familiar with the growing vanlife community, but I learned of it and see it as an intriguing lifestyle possibility. It allows you to travel and stay in National Forest and BLM land for free (in the USA) and relatively cheaply at campgrounds etc.. People also live in them in cities while traveling stay at welcoming businesses like Walmart. Anyway you can read more about the vanlife in posts on my Freelance Lifestyle, Finance and Entrepreneurship Blog.

This video shows a cool way to wire a thermometer to your car/van so that the van starts when the AC (or heat) is needed. This is some cool home engineering.

Most pursuing the vanlife now use solar energy, which is great in many ways. It is difficult (expensive) to create a solar based system that can run an AC. The option in the video is intriguing. And it is a cool illustration of home engineering. I hope you enjoy it.

Elephants Learn to Cooperate to Reach Their Objective

This clip shows elephants learning to work together to achieve what they can’t achieve alone (from BBC’s Super Smart Animals). It is interesting to see what animals are capable of. See the related post links for more amazing animal behavior.

14 Year Old Signs $700,000 MOU for a Drone to Detect and Defuse Land Mines

Harshwardhan Zala, from Gujarat, India has signed an agreement worth Rs. 5 crore (US$733,940) to explore the possibility of commercial production of a drone created by him which can help in detecting and defusing landmines.

Harshwardhan started work on the prototype of the landmine-detecting drone last year after reading in newspapers about high army casualties due to landmines. Aerobotics7 is the company founded by the 14 years old.

Harshwardhan Zala, 14-year-old trends for Rs 5 crore deal at Vibrant Gujarat Global Summit 2017!

Explaining more about the drone, the zealous 14-year-old said, “The drone is designed to send out waves that cover eight sq. mt area while flying two feet above the surface; the waves detect land mines and communicate their location with a base station. The drone also carries a bomb weighing 50 gram that can be used to destroy the landmine.” Harshwardhan Zala’s proud father Pradhyumansinh is an accountant with a plastic company in Naroda, and his mother Nishaba is a homemaker.

[missing video – removed 🙁 ]

The video has Harshwardhan speaking a bit of English but mainly some other language that I don’t understand. If I understand right, his drone is 98% accurate at identifying mines (where the current solutions are 92% accurate – and much more dangerous for those having to walk around testing). His solution is 17 times faster and 22 times cheaper than the current solutions. Once the mine is detected by the drone through an infrared sensor, a 50 gram detonator will complete the task of defusing it (blowing it up).

This video shows a bit of the drone itself (non-English audio)

A Cougar’s Thousand-Mile Quest to Find a Mate

In the late summer of 2009, a young male cougar set off from the Black Hills of South Dakota to look for a mate. And kept going—east across the Great Plains to the Upper Peninsula of Michigan and on to New England, through backyards and parking lots, across highways and railroad tracks, driven by the most powerful force on earth.

Over time he showed up in the Twin Cities of Minnesota and in Wisconsin. He disappeared for a couple months, then shows up almost two years later, 30 miles from Manhattan, in Greenwich, Connecticut. In all he probably traveled 2,000 to 5,000 miles, enough to cross the country twice. He forded all the major rivers of the East, navigated highways and an international boundary. It was one of the most spectacular journeys by an animal ever recorded.

Google Cardboard 3d Viewer Helped Surgeons Save Baby’s Life

$20 cardboard toy saves baby’s life

Doctors at Nicklaus Children’s Hospital in Miami used the device to map out an operation they say they couldn’t have envisioned otherwise.

“It was mind-blowing,” says Cassidy Lexcen, the baby’s mother. “To see this little cardboard box and a phone, and to think this is what saved our daughter’s life.”

Google Cardboard is a virtual reality and augmented reality platform developed by Google for use with a head mount for smart phone. Just get a simple cardboard holder you wear like goggles and an app for Android or iOS and you can view cool 3d virtual realities.
