Except CPU designs from three years ago are no longer considered current, and robots are built around CPUs (that is, if it lacks a CPU, it is not a robot), so three years is long enough to obsolete a vital component.
- exDM69 12y agoAll of these are running on micro controller or similar embedded platforms that are are significantly slower to change than consumer CPUs. Calling them obsolete is not a realistic stance to take. Some of the hardware has changed over the years, but the changes have been mostly to the sensors used and other peripherals, they are still using the same CPUs they did a few years ago and they're definitely not obsolete.
- matheweis 12y ago> they are still using the same CPUs they did a few years ago Not true; at the writing of the article, the Pixhawk board was using the LPC2148, and today it uses the STM32F427... who knows what else has been changed over the years as well?
- exDM69 12y agoYeah, that's possible... I didn't go through all of them, but some had remained essentially the same, e.g. the OpenPilot board had changed some sensors but is still using the same CPU as far as I can tell. But that's really besides the point, the CPUs they were using have not really turned obsolete like GP said. Even the STM32 F4 series you mention was released in 2011, before this article was written. And that's the latest generation of the STM32 series, so it hasn't gone obsolete.
