Robot Gift Guide 2022

Your yearly selection of awesome robot gifts

IEEE Spectrum (Robots: Companies)

It’s been a couple of years, but the IEEE Spectrum Robot Gift Guide is back for 2022! We’ve got all kinds of new robots, and right now is an excellent time to buy one (or a dozen), since many of them are on sale this week. We’ve tried to focus on consumer robots that are actually available (or that you can at least order), but depending on when you’re reading this guide, the prices we have here may not be up to date, and we’re not taking shipping into account.

And if these robots aren’t enough for you, many of our picks from years past are still available: check out our guides from 2019, 2018, 2017, 2016, 2015, 2014, 2013, and 2012. And as always, if you have suggestions that you’d like to share, post a comment to help the rest of us find the perfect robot gift.

The Women Behind ENIAC

A new book tells the story of how they broke a computer-science glass ceiling

If you looked at the pictures of those working on the first programmable, general-purpose all-electronic computer, you would assume that J. Presper Eckert and John W. Mauchly were the only ones who had a hand in its development. Invented in 1945, the Electronic Numerical Integrator and Computer (ENIAC) was built to improve the accuracy of U.S. artillery during World War II. The two men and their team built the hardware. But hidden behind the scenes were six women—Jean Bartik, Kathleen Antonelli, Marlyn Meltzer, Betty Holberton, Frances Spence, and Ruth Teitelbaum—who programmed the computer to calculate artillery trajectories in seconds.

The U.S. Army recruited the women in 1942 to work as so-called human computersmathematicians who did calculations using a mechanical desktop calculator.

Accelerate Battery Development with Unified Design, Modeling and Simulation

Our world is becoming more dependent on batteries. The value chain from material suppliers to battery makers to automotive and industrial vehicle developers is under pressure to optimize battery performance for a wide range of conditions while ensuring safety.

However, batteries are high in mass and require rare materials, life between charges needs increased, and questions remain about long-term recyclability. Meeting these challenges requires advanced engineering methods: including chemistry, cell engineering, module and pack engineering.
