There are many ways to control a robot arm, with the simplest being a sequential list of rotation commands for the motors. But that method is very inefficient when the robot needs to do anything complex in the real world. A more streamlined technique lets the user move the arm as necessary, which sets a […]
Pipelines are integral to our modern way of life, as they enable the fast transportation of water and energy between central providers and the eventual consumers of that resource. However, the presence of cracks from mechanical or corrosive stress can lead to leaks, and thus waste of product or even potentially dangerous situations. Although methods […]
Many types of medications (such as anti-depressants like SSRIs) can have a very negative effect if they aren’t taken on a regular basis. Even taking them a few hours late can harm a person’s mood and cause physical discomfort. But remembering to take pills at the proper time can be tricky — even setting an […]
Many people find the subjectivity of art to be frustrating, but that subjectivity is what makes art interesting. Banksy’s self-shredding art piece is a great example of this. The original painting sold at auction for $1.4 million — and then it shredded itself in front of everyone. That increased its value and the now-shredded piece, […]
With an array of onboard sensors, Bluetooth® Low Energy connectivity, and the ability to perform edge AI tasks thanks to its nRF52840 SoC, the Arduino Nano 33 BLE Sense is a great choice for a wide variety of embedded applications. Further demonstrating this point, a group of students from the Introduction to Embedded Deep Learning […]
Inspired by game nights with her family, Lorraine Underwood from element14 Presents wanted to build a project that would be both fun and playable many times over. Based on these parameters, she opted to design and construct her own take on an air hockey table that would be capable of keeping score automatically. The base of the air hockey […]
You would probably recognize a thermal printer as the thing that spits out receipts at a cash register. They offer a two key advantages: they do not require ink cartridges and they are compact. But because they print by applying heat to special paper that darkens when hot, they have low resolution and fidelity. If […]
Many people (especially those with autism spectrum disorder) have difficulty communicating with others around them. That is always a challenge, but becomes particularly noticeable when one cannot convey their emotions through body language. If someone can’t show that they’re not in the mood to talk, that may lead to confusing interactions. To help people express […]
Spectrum analysis is a technique that allows someone to observe the amplitude of various frequency ranges within a signal. The most common use case is in the world of audio engineering, as it is useful for tuning audio output. It can, for example, show you that a particular audio signal has little amplitude in the […]
Senior care homes may get a bad rap in popular culture, but they serve a legitimate and important purpose. As people age, their requirements for care can exceed the capability of their families. When that becomes the case, professional care may be prudent. To help those professionals care for residents, Hayden designed this system that […]
