For the past decade, two television display technologies—liquid crystal and plasma—have fought for supremacy, and although the LCD won the battle, it is about to lose the war. A third contender’s star is rising: the organic light-emitting diode, or OLED.

For Better or Worse, Tesla Bot Is Exactly What We Expected

Tesla fails to show anything uniquely impressive with its new humanoid robot prototype

Elon Musk unveiled the Optimus humanoid robot at Tesla's AI Day 2022.

At the end of Tesla’s 2021 AI Day last August, Elon Musk introduced a concept for “Tesla Bot,” an electromechanically-actuated, autonomous bipedal “general purpose” humanoid robot. Musk suggested that a prototype of Tesla Bot (also called “Optimus”) would be complete within the next year. After a lot of hype, a prototype of Tesla Bot was indeed unveiled last night at Tesla’s 2022 AI Day. And as it turns out, the hype was just that—hype.

While there’s absolutely nothing wrong with the humanoid robot that Musk very briefly demonstrated on stage, there’s nothing uniquely right, either. We were hoping for (if not necessarily expecting) more from Tesla. And while the robot isn’t exactly a disappointment, there’s very little to suggest that it disrupts robotics the way that SpaceX did for rockets or Tesla did for electric cars.

You can watch the entire 3+ hour livestream archived on YouTube here (which also includes car stuff and whatnot), but we’re just going to focus on the most interesting bits about Tesla Bot/Optimus.

"Nothing About Us Without Us"

Assistive technologies are often designed without involving the people these technologies are supposed to help. That needs to change.

Before we redesigned our website a couple of years ago, we took pains to have some users show us how they navigate our content or complete specific tasks like leaving a comment or listening to a podcast. We queried them about what they liked or didn’t like about how our content is presented. And we took onboard their experiences and designed a site and a magazine based on that feedback.

So when I read this month’s cover story by Britt Young about using a variety of high- and low-tech prosthetic hands, I was surprised to learn that much bionic-hand development is conducted without taking the lived experience of people who use artificial hands into account.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
