After seeing how Google’s Duplex AI was able to book a table at a restaurant by fooling a human maître d’ into thinking it was human, I wondered if it might be possible for us mere hackers to pull off the same feat. What could you or I do without Google’s legions of ace AI programmers and racks of neural network training hardware? Let’s look at the ways we can make a natural language bot of our own. As you’ll see, it’s entirely doable.
Ever find yourself with nineteen nameless robot vacuums lying around? No? Well, [Aaron Christophel] likes to live a different life, filled with zebra print robots (translated). After tearing a couple down, only ten vacuums remain — casualties are to be expected. Through their sacrifice, he found a STM32F101VBT6 processor acting as the brains for the survivors. Coincidentally, there’s a project called STM32duino designed to get those processors working with the Arduino IDE we either love or hate. [Aaron Christophel] quickly added a variant board through the project and buckled down.
Of course, he simply had to get BLINK up and running, using the back-light of the LCD screen on top of the robots. From there, the STM32 processors gave him a whole 80 GPIO pins to play with. With a considerable amount of tinkering, he had every sensor, motor, and light under his control. Considering how each of them came with a remote control, several infra-red sensors, and wheels, [Aaron Christophel] now has a small robotic fleet at his beck and call. His workshop must be immaculate by now. Maybe he’ll add a way for the vacuums to communicate with each other next. One robot gets the job done, but a whole team gets the job done in style, especially with a zebra print cleaner at the forefront.
If you want to see more of his work, he has quite a few videos on his website demonstrating the before and after of the project — just make sure to bring a translator. He even has a handy pinout for those looking to replicate his work. If you want to dive right in to STM32 programming, we have a nice article on how to get it up and debugged. Otherwise, enjoy [Aaron Christophel]’s demonstration of the eight infra-red range sensors and the custom firmware running them.
Just because a system becomes obsolete for most of us doesn’t mean that everyone stops working with them. Take a look at this brand new game for the Amiga 500 called Worthy, which is sure to make most of us regret ever upgrading our home computers, despite the improvements made since 1987.
The group who developed the game is known as Pixelglass and they have done a lot of work on this platform, releasing several games over the past few years. Their latest is Worthy, an action-adventure game that looks similar to the top-down perspective Zelda games from the SNES. It’s an impressive piece of work for a system that few of us own anymore, but if you have one (or even if you have a good emulator) you might want to give it a whirl.
If developing games for retro systems is your style, this isn’t limited to personal computers like the Amiga. We’ve seen development platforms for the Super Nintendo that will let you run your own code, and even other methods for working with the Sega Saturn if you’re feeling really adventurous.
