Ryan--Excellent post. My company recently installed a Cartesian robotic system that uses steppers for positioning a dispensing head providing a bead of RTV. I definitely wish I had your post prior to investigating this project. Being a mechanical engineer, there always seems to be some "magic" relative to electrical engineering and certainly electronics. Topics such as this one really gets to the basics in quick fashion. Again, good post.
Thank you for your positive comments. These solutions not only save time, but save money with a high level of analog integration and just enough digital integration to take the burden off the MCU. Two things we all wish we had more of: time and money!
Excellent post. Thanks for the entertaining explanation for how integrated motion solutions play out with steppers and BLDC motors. It's easier to simplify when motion control can be reduced to the component level and integrated capabilities. Thanks for the update.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
