Frozen Pi

It's no secret that this blog once harboured aspirations to hit the dizzying heights of advanced robotics on a meagre budget.  Rather foolishly - armed with a Raspberry Pi (or two) and an assortment of motors procured from eBay - we believed that we could start our very own Tyrell Corporation, and in essence, create a fleet of replicants experiencing a distinctly human mid-life crisis.

We have seemingly succeeded in stumbling through over 30 little experiments, with a couple of random "projects" to boot.  Yet the holy grail of creating a paranoid android that forces Harrison Ford to become uncharacteristically philosophical about what it means to not(?!) be a robot, or even the goal to fabricate ourselves Dolly the electric sheep, seem even more far-fetched now than the plot of a typical Uwe Boll film.

But it hasn't all been in vain.

Because where we have landed is where most other avid tinkerers of microprocessors and electronics eventually end up... a strange (yet…

This is it, our dedicated Terran readership (yes, all 3 of you).

We've reached the very last instalment in our third, and still incredibly unspectacular DIY robotics series - Rosie 2.0.  What has at times felt like a never-ending, rambling blog has turned into an eclectic curation of often unrelated Raspberry Pi and ESP8266 based activities (assembled under the highly misleading guise of "robotics").  And - quite frankly and not so unusually for us - we lost our bearings somewhat.  OK, badly.

Except, actually, we didn't get completely and utterly lost.

During our very last expedition, we took our GPS-enabled Raspberry Pi around the 10 peaks of the Brecon Beacons.  And perhaps, we inadvertently proved that there are some ingredients required for autonomous navigation that can be obtained on the fly (as opposed to from a fly, because that would be kind of weird) - for cheap.  In other words, you don't have to be an eccentric billionaire with a penchant to name your…
