Improving a robot controller: Replacing tanh(x) with sin(arctan(x))
Steve Taranovich 5/6/2019 2 comments
Most of us probably have never used the hyperbolic tangent function tanh(x) or the sin(arctan(x)) reference function since our university days. But these functions enable a kinematic controller. Kinematics determines the position and orientation movement of an end-effector on a robotic arm as a function of the joint coordinates.
Surgical revolution: Robotics
Steve Taranovich 4/24/2019 Post a comment
Surgical Robotic Systems are no longer a science fiction idea. These kind of systems, although still in their infancy, are able to enhance a human surgeon’s talent with more accurate and less invasive techniques.

NYU Wireless, Professor Rappaport, speaks out about the advent of 6G
Steve Taranovich 3/28/2019 1 comment
The Federal Communications Commission has begun considering opening up a new spectrum of radio waves that researchers believe could become integral to the sixth generation of wireless communications (6G) as part of the never-ending quest to send more data more quickly over the air.
Nikola Tesla: EDN and Planet Analog's best articles
Steve Taranovich 2/19/2019 2 comments
Nikola Tesla was an extraordinary, but very eccentric inventor. His rivalries with Thomas Edison are famous. He died more than 75 years ago, but his discoveries and ideas have helped shape modern electricity, including Wireless Power
Metastability in Space
Steve Taranovich 1/28/2019 2 comments
Metastability can cause a spacecraft electronic failure. It may render a very expensive spacecraft/satellite unusable and if the spacecraft is manned, there could be lives in danger
LiDAR damage to camera at CES?
Steve Taranovich 1/16/2019 11 comments
Recently, AEye, was demonstrating their LiDAR system at CES in Las Vegas. A man using his new $1,198 Sony camera found that his photographs were damaged after he took pictures of AEye’s LiDAR LASER scanning system
What's a Gerber Variable Scale?
Steve Taranovich 1/7/2019 Post a comment
Back in the early 60s, there were really no computers or electronic calculators generally available to engineers. The Gerber Variable Scale was a time-saver for designers.
Up close and personal with the Shuttle Independence
Steve Taranovich 12/20/2018 Post a comment
While in Houston recently, I visited the Space Center Houston and toured the 80-ton shuttle replica Independence, mounted atop the historic and original NASA 905 159-ton shuttle carrier aircraft (SCA), which was the first of the SCAs.
MEMS, MITRE, and DARPA

On Thursday, October 11, the Soyuz MS-10 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan. Soon after the launch, there was a problem with the booster and the launch ascent was aborted
ElectroMagnetic Pulse (EMP)---What's your Plan B?
Steve Taranovich 9/30/2018 12 comments
An EMP is a high intensity electromagnetic pulse having broad frequency spectrum covering from low frequencies to the VHF and UHF bands. EMP is still a serious threat to the electronic systems and communication systems.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
