Introduction:      FreeBSD is a "UNIX like" opensource operating system. Not like Linux, which provides only the kernel, FreeBSD provides full fledged - fully equipped operating system. The history of the operating system dates back to 1993. And it is the most popular BSD (Berkeley Software Distribution) based operating system available in the open source community.   I would recommend you to read the history of FreeBSD a little. Links are available here: https://en. ...
Rice farmers in Asia have always used ducks to keep their plants pest-free, acting as a healthier, natural solution to pesticides. Ducks work in rice fields by waddling around flooded areas, rooting out weeds and devouring insects. Their manure is an added bonus too, providing fertilizer for farmers. Nowadays, times are changing, and with recent technological advancements, ducks will no longer be a necessity for farmers to rely on. Their prowess could eventually be replaced by robots. Named af ...
Introduction The NVIDIA Jetson Nano is a compact board approximately 70x45mm in size, with a large heatsink : ) It's got a very powerful microchip, the NVIDIA Tegra X1, which contains four ARM applications processor cores, as well as 128 graphics processing units (GPU). GPUs are used for more than graphics purposes, because it turns out that some of the interesting applications for computers today, to do with neural networks, which can be used to recognise patterns with ever increasing accuracy, ...
Scientists have designed and developed a robotic shrimp that's eerily similar to the pistol shrimp. The pistol shrimp is just a few inches in length and has a massive claw that is so strong it can knock out its prey with the shockwave when the claw snaps. Once the claws come together, bubbles develop, collapse and shoot out a bolt of plasma that creates a flash of light with temperatures reaching 8,000 degrees Fahrenheit. Researchers explain how they designed a robotic claw inspired from the pis ...
Hot Wheels has always been great at giving users the virtual experience for the past few years when it comes to toy cars. Their toys like Hot Wheels AI, Mindracers and Augmoto all have been focused on making it a driving experience that is  played like a video game. This year, Hot Wheels has finally created something that will please their fans - the new TechMods set. The vehicle is controlled by an app, and you build the vehicle yourself and which can be controlled with your phone. The pro ...
I'm looking for  a $1 single board computer or controller that can control 60 LEDs, a buzzer, 2 three digit seven segment displays and one buzzer.  This controller must be acurate to a second. is there such a controller?  Is there a controller or a group of components in this cost range? ...
Introduction I recently needed a small form-factor computer and I was lucky enough to get given an Intel NUC (model NUC7i3DNKE) as part of my work. I thought I’d take some photos of it as I explored it.   My primary use-case will be to use it for demos. It is very small so it can be taken with me when I travel. However, there are other uses planned for it too.   In the drive for a silent environment to work in, I hardly ever turn on the desktop PC. The laptop works fine for m ...
NASA to send robotic bees to Mars in an attempt to study the planet further. The space agency has implemented this idea ahead of sending humans to our neighbor planet. The image shows a concept of how Marsbees would work. (Photo via NASA)   What’s the next step after Mars rovers? Swarms of robots!   Dubbed “Marsbee,” a swarm of robotic bees are being planned to boost and support a central rover. The rovers have some limited capacities in their technology, but that ...

Raspberry Pi 3

Posted by colonel_dirty Mar 10, 2018
Salutations I am a student at Northern Arizona University,       I am currently a participating in a robotics competition. I have a degree in Mechanical engineering and I am currently pursuing a second degree in computer science. The robot we are making for the competition is a soccer playing robot this is my first time doing programing like this. I have an understanding in Python and Java. We are using a Raspberry Pi 3 for the brains of the robot. I have installed Ras ...
Introduction The Leap Motion Controller is something that can be used as an input device for a computer (desktop/laptop or a single board computer). It can be placed on the desk, or if desired can be strapped onto a virtual reality (VR) headset if you have one. In brief, when it sees your hand or hands, it can analyse them to figure out where your fingers, palms and so on, are in three dimensional space. It can also figure out certain movements such as swipes. You could use it for controlling st ...

I finally purchased a couple of PocketBeagles, I knew they would be small, but it is still amazing to see it close-up! It is very thin too, it measured 4.60mm (the highest point is the surface of the Octavo module). For connections, I purchased 2x9way total 18-way header pins because these are cheaper than 2x18way. A total of four of these are needed to fully connect to the PocketBeagle, although that might not be necessary for all projects. Note that the header pins are connected to the u ...
The Volocopter saw its first tethered passenger flight during CES 2018. (Image credit: Volocopter)   German drone manufacturer Volocopter recently demonstrated its first manned flight at this year’s CES, of course, it was tethered and indoors but it’s still a milestone never the less. With the onset of autonomous vehicles, it was only a matter of time before autonomous drones transitioned into pilotless taxis set to enter into service sooner than we might think.   The Vol ...
The seventh successful launch of Blue Origin’s New Shepard reusable suborbital spacecraft. (Image credit: Blue Origin)   The Skywalker’s have always been a family of many talents- young Anakin became a notable Sith Lord, his son Luke became a Jedi Knight, his daughter lead a great Rebellion
ot-so-great Resistance, and distant cousin Mannequin made it through a successful test flight aboard a reusable suborbital spacecraft. “Always two there are; no more, no less-” ...
While the city won’t be outright banning these bots, they are now not allowed on crowded city sidewalks. These bots have a lot of rules to follow before they hit the streets (Image via Reuters)   When it was first introduced, the idea of delivery robots sounded absurd. Now, it’s close to becoming a reality, but maybe not in San Francisco. Companies are currently testing out these bots, but are hitting a road block when it comes to San Fran. Recently, the city’s Board of S ...
