Georgia Tech Announces Vibration Powered Ant-sized Micro Robots

A 3D-printed robot of roughly 2 mm in length almost of the size of the smallest ant is the latest entrant in the world of micro-bots.  Interestingly, these bots move in response to vibration from the piezoelectric actuators, ultrasound source or even a small speaker.

According to a research paper released by the School of Electrical and Computer Engineering at the Georgia Institute of Technology, these ant-sized robots is likely to revolutionize the tech space as these could be used to:

 “sense environmental changes, move materials and even repair injuries inside the human body one day”

Depending on the configuration, these “micro-bristle-bots” responds differently to different vibration frequencies. This variable frequency response mechanism allows researchers to control individual ant-sized bots. The mobility response is quite amazing. According to paper, these bots can cover four times their own length in a second.

Azadeh Ansari, an assistant professor at the institute says:

 “We are working to make the technology robust, and we have a lot of potential applications in mind.”

Adding further she said that the team is working at the intersection of mechanics, electronics, biology, and physics. It’s a very rich area and there’s a lot of room for multidisciplinary concepts, she added.

As there is no battery of that minuscule size to fit within bots, this vibration response mechanism and control system could change the dynamism of the micro-bot research. Although there are immense future possibilities, as of now the team is just dealing with some tiny prototypes.

The paper says that the bot consists of a piezoelectric actuator glued onto a polymer body that is 3D-printed using two-photon polymerization lithography (TPP). Actuator induced vibration to move the springy legs up and down, propelling the micro-bot forward.

Ansari said:

“As the micro-bristle-bots move up and down, the vertical motion is translated into a directional movement by optimizing the design of the legs, which look like bristles.”

She added that the legs of the micro-robot are designed with specific angles allowing them to bend and move in one direction in resonant response to the vibration.

Move Over SpaceX. Amazon is planning to launch Thousands of Internet Satellites Too

In April 2019, Amazon made its intention clear that it is going to enter the internet satellite business. Following the footsteps of Starlink and SpaceX satellite system, Amazon plans to launch thousands of internet satellites in the coming future. They have already filed their application with the FCC.

Amazon is calling its system Project Kuiper, and they are all set to do business. Based on the application to the Federal Communications Commission, they want to put 3,236 broadband satellites into orbit. This pales in comparison to SpaceX’s Starlink system, which aims to put almost 12,000 satellites into orbit in the next coming years. This is one of the biggest ventures.

In their FCC filing for Project Kuiper, Amazon states:

“There are almost 4 billion people in the world who don’t have access to reliable broadband internet. They mean to help fill that gap in global service with their ambitious project.”

Right now there are already 5000 satellites in orbit around the earth. These constellations of satellites from Amazon and SpaceX will increase that number upwards to 20000 including all the other satellites being launched monthly by the governments and companies all around the world.

These satellites will be in Low Earth Orbit which is prime real estate in space. LEO extends up to 2000 km, although strictly speaking, altitudes is not the best way to delineate LEO. The bulk of humanity’s satellites are in LEO, including the Hubble Space Telescope and the International Space Station.

Satellites from Project Kuiper are going to be grouped into 98 different orbital planes. Not just that, but they will also be grouped into two orbital shells: 590 km and 630 km.

There is more than physical space to be managed and allotted to Amazon, SpaceX, and other satellite internet providers. They are required to share broadcast spectrum space too.

Project Kuiper’s satellites are known to operate in the Ka-Band radio frequencies. This is the same one as used by satellite phone company Iridium, among others. There are procedures established by companies to share frequencies without interfering with each other.

V3 Supercharger From Tesla Can Charge Up To 1500 Electric Vehicles In A Single Day

V3 Supercharger From Tesla Can Charge Up To 1500 Electric Vehicles In A Single Day

Tesla has recently opened a large next-generation electric vehicle charging station in Las Vegas. It is known to combine the company’s core products into one single sustainable energy ecosystem. This is done to fulfill a vision of Elon Musk, CEO.

The new V3 supercharger is known to support a peak rate of up to 250 kilowatts. It has been designed to reduce the charging time for its electric vehicles. The V3 supercharger was unveiled by Tesla in March at its Fremont, Calif factory. A second V3 supercharger is located in Hawthorne, Calif close to the Tesla Design Studio. Both the sites were initially used as test sites, lack two important Tesla products.

The one located in Las Vegas is considered to be the first V3 supercharger. It is notable not only because of its size but there are 39 chargers at the station. This V3 supercharger also uses Tesla solar panels along with its Powerpack batteries in order to generate and store the power required to operate the chargers. As a result, the entire system generates its own energy and passes it along to thousands of Tesla vehicles.

The new supercharger located off the Las Vegas strip, below the High Roller on the LINQ promenade was constructed on Caesars Entertainment Property. The site is actually a part of Caesars Entertainment’s goal to cut down on greenhouse gas emissions 30% by 2025.

There are caveats to the capabilities of this supercharger station. Only one Tesla vehicle, model 3 long range iteration can charge at the maximum rate of 250 kW. The 250 kW results in up to 180 miles of range added to the battery in 15 minutes.

New models, Model S and Model X are designed to charge up to 200 kW rate.

Improvements to charging times are critical for the company.  wait times at supercharger stations can be lengthy.

In the past, the company has said:

“These improvements will allow the supercharger network to serve more than twice as many vehicles per day at the end of 2019 compared with today.”

Android Auto phone interface went for many on Android Q Beta 5

Android, the king of the mobile operating system with 76%, is consistently in innovative mode. As announced in May, Google has started to the killing of Android Auto phone interface. Some Reddit users reported that in the Android Q Beta 5 update on Pixel, the icon of Android Auto app is disappearing and there is no option to start the app from the phone. The tech giant plans to replace it with the Driving Mode.

However, the same user said that the Android Auto interface is still available on the Google Play Store but an option to launch the app is not there. The Auto is not completely gone. The launchable app might be missing but it one can still connect with car’s infotainment system provided your car supports the Google software.

The Mountain View, California-based giant is gearing up to revolutionize the fast-evolving self-driving car industry. The all-new Assistant Driving Mode is definitely going to be more promising as compared to the Android Auto.

Going by the past experience of delay in the Google Play Music and YouTube Music features parity, experts are a bit apprehensive about the time Google will take to complete the replacement.

Google launched Android Q Beta 5 launches on July 10 taking a step forward towards the final release.  It is time for you to test the compatibility of your apps and make sure they are ready. The tech major plans to lunch one more Beta release before the consumer launch scheduled later this quarter.

The Beta 5 update includes the latest Android Q system images for Pixel and Android jEmulator. This also includes the final Android Q developer APIs (API level 29), the official API 29 SDK, and updated build tools for Android Studio.

In gesture navigation space Google intends to switch users to 3-button navigation when they are using custom button launcher, starting in Beta 6. Google assures that they will address all remaining issues in a post-launch update allowing all users to switch to gestural navigation.

Alphabet Inc (GOOGLE) stock opened at US$1146.73 and closed at US$1153.46, up 0.26% on July 16.
