II. Rosie Patrol



10 steps to convert our Rosie into Rosie Patrol - the greatest superhero of them all.  With a logo.

We continue to use the Raspberry Pi and Raspbian OS, and write even more code using the Python programming language.  We'll introduce lots more interaction with the outside world, and hacking of real-life objects, using servo motors, relays, dot LED matrix displays and GPS receivers.  And to help us do all of this, we'll play around with serial transmission of data (SPI), pulse width modulation (PWM) of signals, and venture into the world of application programming interfaces (APIs) so that Rosie Patrol can rely on the help of other computers that are much more knowledgable than her.

And... oh yes... we'll finally get to play with a 3D printer.  What could possibly go wrong?

1Lights in shining armour Use a relay to cycle through the lights on a head torch
2I'm just angling around Play around with servo motors to make stuff move
3Eye would like to have some I'sMake eyes using dot LED matrix displays, and control them using SPI
4Eh, P.I?Create and work with APIs to remotely make stuff happen
5Lights, camera, satisfactionTake photos using the Pi and a camera
6Beam me up, Rosie!Use a GPS receiver to track you exact location on Earth
7a, b, see, d Pick out letters from photos using Google Cloud Vision API
8Code: readUse Google Text-to-Speech to read books out aloud
9Farcical fartificial intelligenceForm random opinions about surrounding objects using Google Cloud Vision API
10Facial deconstructionUse a 3D printer to produce robot parts

You'll get to tackle:

  • Raspberry Pi
  • Raspbian operating system (basically Linux)
  • More hardware (relays, dot LED matrix displays, camera, GPS receiver...)
  • Python programming language, including use of APIs
  • Optical character recognition, for reading letters from pictures
  • Different types of electronic signals, like Serial Peripheral Interface (SPI), and Pulse Width Modulation (PWM)...
  • And finally get to play around with 3D printers

Show me the proof!

Break an egg! You've got to be in it to win it.

What the 'egg? It turns out: parenting is actually quite hard.

Not least because you suddenly find yourself responsible for one, two, or - in our household - three little miniature versions of us that need to be kept well away from the soldering iron. Or the 3D printer. Or that marauding hexapod that you forgot to power off before you left for work in a hurry.  But to compound matters further, you find yourself well and truly ambushed - financially.  You are at all times being pressurised by dark forces beyond your control to make an investment, however dubious the return.

That's right.  Clearly, you will be considered an abject failure as a responsible adult if you don't purchase the latest, trendy parenting gizmo. That feeding bottle sterilising kit clinically proven to kill all known bacteria through the science of nuclear fission. Or that titanium alloy buggy guaranteed not to crumple in the event of a sudden collision with falling Soviet-era space debris.  Evidently,…

Tea minus 30

We're fast approaching Christmas time.  And if robots were to make one simple observation about the human species during the Christmas festivities, it's that they watch a lot of TV.  A LOT.  Often, accompanied by an inappropriate amount of greenhouse gas-producing food.  Stuff you don't normally eat during the remainder of the year - for good reason.

And most so-called shows on TV are boring to robots like Rosie.  After all, why watch a minor subspecies of the human race - celebrities - stumble awkwardly around the dance floor, dressed like a faulty, sparking circuit board?  Such branch of entertainment doesn't require robots to engage any of their proud circuitry.  Their processors remain idle.  Memory under-utilised.

But if robots are to be part of people's homes (and blend in), they need to look at least a little interested in some of this irrational nonsense.  Nobody likes a party pooper.  A killjoy.  And this is where a certain subgenre of TV entertainment co…

Raspberry bye, hello

Let us make this very clear from the onset of this exotic excursion.

This is not a case of Raspberry Bye. Our relationship with our favourite single-board computer hasn't at all soured. In fact, we've become wholly inseparable. There's been many months of undeniable fun that's been had with the venerable computer strangely named after an edible fruit. To the extent that our relationship requires a healthy break. And quite frankly, our Pis require a well earned summer holiday to do whatever it is that robots and computers do during their time off. Crash. Burn. Refuel (with questionable toxins). Not at all unlike their human counterparts. And ultimately, it would be nice if they could return to a brand new, adorable pet waiting for them at home, a likeable little companion that they can just get along with.

Well, we visited a pet shop, but couldn't find anything as small and smart as this adorable pup we stumbled up on while searching the Internet for a new, miniat…
