Created by Wissam Tedros, RoDog is a reliable and hobby-level quadruped robot constructed out of accessible parts. The project implements a dozen RC servos actuators, measurement units such as a gyroscope, accelerometer, magnetometer, and unity for inertial measurement, an ESP32-CAM for streaming and WiFi connectivity, an OLED display, and more, all within a 3D-printed casing.

Entirely open source, Tedros’ post includes the BOM and all necessary files, as well as notes on mechanical design and assembly and data obtained from a MATLAB Simulink trial of the inverse kinematic control used with the embedded system. RoDog features a custom STM32F4 board for its brain, with the design available in full detail. The bot is quite compact at 20×10×5 cm, and the 12 motor controller board incorporates position and current feedback.

It is still in development 0, having gone through many iterations and tweaks, most of which are logged in the project files. However, its current form should perform well as a hobbyist’s robotic pet with room for add-ons.

Wireless implantable devices and IoT could manipulate the brains of animals from anywhere around the world due to their minimalistic hardware, low setup cost, ease of use, and customizable versatility.

A new study shows that researchers can remotely control the brain circuits of numerous animals simultaneously and independently through the internet. The scientists believe this newly developed technology can speed up brain research and various neuroscience studies to uncover basic brain functions as well as the underpinnings of various neuropsychiatric and neurological disorders.

A multidisciplinary team of researchers at KAIST, Washington University in St. Louis, and the University of Colorado, Boulder, created a wireless ecosystem with its own wireless implantable devices and Internet of Things (IoT) infrastructure to enable high-throughput neuroscience experiments over the internet. This innovative technology could enable scientists to manipulate the brains of animals from anywhere around the world. The study was published in the journal Nature Biomedical Engineering on November 25.

SpaceX’s newest drone ship is on its way out into the Atlantic Ocean for a Starlink mission that will break the company’s record for annual launch cadence.

Somewhat confusing known as Starlink Shell 4 Launch 3 or Starlink 4–3, the batch of 53 laser-linked V1.5 satellites is scheduled to fly before Starlink 4–2 for unknown reasons and at the same time as Starlink 2–3 is scheduled to fly before Starlink 2–2 on the West Coast. Regardless of the seemingly unstable launch order, perhaps related to the recent introduction of Starlink’s new V1.5 satellite design, drone ship A Shortfall of Gravitas’ (ASOG) November 27th Port Canaveral confirms that SpaceX is more or less on track to launch Starlink 4–3 no earlier than (NET) 6:20 pm EST (23:20 UTC) on Wednesday, December 1st.

In a bit of a return to stride after launching 20 times in the first six months but only three times in the entire third quarter of 2021, Starlink 4–3 is currently the first of four or even five SpaceX launches scheduled in the last month of the year. Nevertheless, if Starlink 4–3 is successful, it will also set SpaceX up to cross a milestone unprecedented in the history of satellite launches.

On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks.

The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.

One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.

What does it mean when someone calls you smart or intelligent? According to developmental psychologist Howard Gardner, it could mean one of eight things. In this video interview, Dr. Gardner addresses his eight classifications for intelligence: writing, mathematics, music, spatial, kinesthetic, interpersonal, and intrapersonal.

A team of researchers from TU Delft managed to design one of the world’s most precise microchip sensors. The device can function at room temperature—a ‘holy grail’ for quantum technologies and sensing. Combining nanotechnology and machine learning inspired by nature’s spiderwebs, they were able to make a nanomechanical sensor vibrate in extreme isolation from everyday noise. This breakthrough, published in the Advanced Materials Rising Stars Issue, has implications for the study of gravity and dark matter as well as the fields of quantum internet, navigation and sensing.

One of the biggest challenges for studying vibrating objects at the smallest scale, like those used in sensors or quantum hardware, is how to keep ambient thermal noise from interacting with their fragile states. Quantum hardware for example is usually kept at near absolute zero (−273.15°C) temperatures, and refrigerators cost half a million euros apiece. Researchers from TU Delft created a web-shaped microchip sensor that resonates extremely well in isolation from room temperature noise. Among other applications, their discovery will make building quantum devices much more affordable.

To address the growing threat of cyberattacks on industrial control systems, a KAUST team including Fouzi Harrou, Wu Wang and led by Ying Sun has developed an improved method for detecting malicious intrusions.

Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. In the past, these systems relied on expensive dedicated networks; however, moving them online has made them cheaper and easier to access. But it has also made them more vulnerable to attack, a danger that is growing alongside the increasing adoption of internet of things (IoT) technology.

Conventional security solutions such as firewalls and antivirus software are not appropriate for protecting industrial control systems because of their distinct specifications. Their sheer complexity also makes it hard for even the best algorithms to pick out abnormal occurrences that might spell invasion.

It’s a cool concept; the blades cant get caught, or stuck, or broken. but, it’s pretty loud, there’s no audio in the demo videos. Still, i think a flying drone would be superior for exploring underground structurers and caves, til it hit a door or something anyways. Anyhow, i think the flight system should focus on some kind of a total silence ion drive.

It was three years ago that we first heard about the Cleo, a robust, donut-shaped prototype drone made by Cleo Robotics. Well, its successor is now commercially available, under the new (and apt) name of the Dronut X1.
