Watch NASA's OSIRIS-REx Spacecraft Attempt to Capture a Sample of Asteroid Bennu
Let's do this, OSIRIS-REx! Time to journey #ToBennuAndBack. Tune in to our live broadcast as our spacecraft descends to the surface of asteroid Bennu, touches down for a few seconds & attempts to capture regolith (rocks and dust) using a “Touch-And-Go,” or TAG, maneuver. The spacecraft must target Bennu’s rocky surface with great accuracy, touching down within a rocky area just 52 ft (16 m) in diameter. During the maneuver, the spacecraft and the asteroid will be approximately 207 million miles (334 million km) from Earth.
Live coverage from Lockheed Martin's facility in Denver, Colorado, with mission managers from the University of Arizona, Lockheed Martin, and NASA's Goddard Space Flight Center begins at 5 p.m. EDT.
The spacecraft is scheduled to depart Bennu in 2021, and to deliver the collected sample to Earth on Sep. 24, 2023. It will be the first U.S. mission to carry samples from an asteroid back to Earth, and the largest sample returned from space since the Apollo era.
10 Amazing Robotic Animals
If you're new, Subscribe! → goo.gl/djmfuX
Technology has really come a long way! And a great way to see that is through the creation of robots. We all played with remote controlled cars at some point and a lot of us today have drones — these pretty much represent the basic concept of robotics: they are machines that perform tasks as they follow our instructions. But what we see in stores doesn’t compare to what is happening inside the labs around the world. Everyday, groups of engineers come together trying to find ways to further develop robotic projects, which a lot of them are inspired by things in nature. Today I’ll be showing you 10 Amazing Robotic Animals — some of them can be easily mistaken for a real animal! Stay tuned all the way to number one and see how far technology has come!
Smartbird
The Smartbird is an ornithopter, which is pretty much an aircraft with flapping wings. It was designed by Festo’s Bionic Learning Network. The Smartbird can take off, fly and land by itself, which makes it a very autonomous robot. It’s one of the robots that best imitates the flight of real birds. Its wings in fact, not only flap but can even twist. An electrical motor in its body, allows its wings to move in a vertical way. When you look at it, the Smartbird can fly almost as perfectly as as an actual bird. From far, you might even think it’s a real one! The Smartbird is a robot that can help researchers understand the birds' flight better, and even improve the way in which airplanes are designed. It can also help in the further development of drone technology and other flying robots in the future.
The Bionic Ant
The Smartbird is not the only robot that Festo has created. They’re actually one of the leading companies in the development of robotic animals. Next on this list, I have another one of Festo’s creations: a swarm of bionic ants. These ants, that are 13 centimeters long, have been designed like real ants, not only on the outside, but also in their behavioral patterns. These ants can communicate with each other to carry on tasks as a community. They come with a small camera within the eyes region and some monitors which allow them to move and perform. They have two batteries that allow them to function wirelessly for up to 40 minutes. If the battery runs out, they can step to the dock and recharge through their antennas.
The Bionicopter
And once again...another creation by Festo! I really want to introduce you to other companies, but the team at Festo is really good at making robotic animals! The bionicopter is one of the most efficient flying robots due to the fact that it is more maneuverable than the others. It’s also known as “The Dragonfly Robot” — although with a body of 19 inches long, it’s quite larger than the real insect! However, this robot moves its wings just like the creature that inspired it. This robot can fly to the front, to the back and make an abrupt stop in mid air. The bionicopter is a great example of what wireless communication can become. This robot can follow commands in real time thanks to its sensors that allow it to assess its surroundings at the same time it receives instructions. This robot is not only smart and efficient, but it’s also very good looking — Its body is covered in blue polyester, which makes it a very beautiful and elegant robot.
The Bionic Kangaroo
When you think of kangaroos, the first thing that might come to your mind is...Australia! But also the way they jump from place to place. With the bionic kangaroo, the creators have implemented a mechanism of repercussion that allows the robot to recover, store and use energy with every jump — just like a real one! The bionic kangaroo is smaller than the real one, and is controlled through an armband that tracks the arm gestures of its bearer so the kangaroo knows where and when to hop. This robot, however, is not meant for you to have it at home, so don’t expect to see it in stores yet! Festo designed it with the hopes of finding ways to use energy more efficiently in the creation of new tools. Since having a pet kangaroo is not really a thing, I do hope they sell this robot to us one day!

In this video I show you how to make a remote controlled spider robot.
Clarification… The introduction of the video is stop motion animation, it was only done to visually enrich the content and to exemplify how the idea was born without using a real spider. I do not intend that you believe that the final result of the product is the same.
Also keep in mind that remote control does not always mean that it is Radio Control, since you can control something remotely even when using a physical connection.
Keep in mind:
The content shown in this video is experimental, everything was done during the recording, if you plan to recreate what is shown here, be careful when using the tools and keep in mind that you must have basic knowledge of electronics and basic tools.
Read the following recommendations if you plan to recreate it.
-Don't make the same size shown here, in spite of having included other 2 motors, a 9-volt battery was used at the end to move and the motors were burned after a while of operation, the problem is solved if it does smaller maybe half or less.
— Get a battery holder for 4 units, it's better and cheaper than doing it manually.
-The engines have to be all similar.

Building a 3.5kWh DIY Solar Generator for $650 — Start to Finish
After having a friend ask several questions regarding a solar generator project he was working on, I decided this would be a good opportunity to build my own solar generator and fully document the process. The total build came out to around $641. This video provides an in-depth look at the process involved in collecting and assembling the battery pack along with the choice of components and some testing.

Breakthrough Solid State Battery — 900 Wh/L Samsung [2020]
Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency.
To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide (NMC for short) mixed with a Sulfide Solid Electrolytes (SSE, show formula on screen), on top of nanocomposite-layer of Silver-Carbon.
All of this is located in between a foil of Aluminum and Stainless steel as the current collectors.
The idea behind this was to remove lithium foil from the mix and have all lithium atoms part of the NMC and SSE. This approach diminishes the costs of the overall battery manufacturing since handling lithium usually needs an oxygen free environment due to its high reactivity.
This is important for a few reasons, in conventional lithium batteries, the anode comprised of lithium moves freely towards the positive electrode during discharge.
Dendrites are formed during the charging process when lithium moves back to its initial location thanks to the free movement enabled by liquid or gel electrolyte.
This is the main limiting factor of how much energy can be store in these batteries since to control this, the amount of lithium available in the system has to be caped, limiting the energy density.

The Future of Energy Storage — Professor Yet-Ming Chiang, MIT
What have been the key battery technology breakthroughs to get us to where we are now? What are some new opportunities for large-scale energy storage & what's MIT doing? What are some key lessons for startups to be successful in the battery industry?
Energy storage will play an increasingly important role in a decarbonized world. From electric vehicles to grid resiliency, batteries will impact the ultimate success of numerous industries that are critical to a low carbon society. Professor Yet-Ming Chiang, one of the world’s most prominent researchers in energy storage, will give a personal perspective on some of the challenges and opportunities for better and cheaper energy storage.
From a historical perspective, battery performance has improved steadily, but now the divergent needs for batteries in high energy density applications such as EVs (and, coming soon, electric aviation), and those for grid storage, which emphasizes ultra-low cost and earth-abundant materials, are becoming clear. He will give examples of emerging innovations that may address these different needs, including solid-state and other batteries that use alkali metal electrodes, and approaches that make use of the most widely available electroactive elements. The expectation is that the audience will come away with a realistic but exciting roadmap of possible areas of innovation for energy storage.
Finally, he will conclude with his personal experiences in building battery enterprises. Battery technologies are notoriously difficult to scale given high technology risk and high development costs. Yet-Ming will share some of the unique lessons learned at startups he has co-founded, including A123, 24M, and most recently Form Energy.
Prof. Chiang's research focuses on the design, synthesis, and characterization of advanced inorganic materials and related devices. Current topics include new cathode and anode materials for lithium ion batteries, phase transformations in electroactive materials, electrochemical device design, electrochemical-to-mechanical energy conversion, self-assembling colloids, and the stability and defect chemical properties of interfaces in inorganic materials.
