Rise Of The Unionized Robots

For the first time, a robot has been unionized. This shouldn’t be too surprising as a European Union resolution has already recommended creating a legal status for robots for purposes of liability and a robot has already been made a citizen of one country. Naturally, these have been done either to stimulate discussion before reality catches up or as publicity stunts.

Dum-E spraying Tony StarkWhat would reality have to look like before a robot should be given legal status similar to that of a human? For that, we can look to fiction.

Tony Stark, the fictional lead character in the Iron Man movies, has a robot called Dum-E which is little more than an industrial robot arm. However, Stark interacts with it using natural language and it clearly has feelings which it demonstrates from its posture and sounds of sadness when Stark scolds it after needlessly sprays Stark using a fire extinguisher. In one movie Dum-E saves Stark’s life while making sounds of compassion. And when Stark makes Dum-E wear a dunce cap for some unexplained transgression, Dum-E appears to get even by shooting something at Stark. So while Dum-E is a robot assistant capable of responding to natural language, something we’re sure Hackaday readers would love to have in our workshops, it also has emotions and acts on its own volition.

Here’s an exercise to try to find the boundary between a tool and a robot deserving of personhood.

Pepper Mill Locks Your Door

Pepper! If you’ve ever tried to grind it, you’ve probably noticed it takes a bit of elbow grease. It’s actually possible to source electric pepper mills to grind it for you, in fact. It just so happens that [MarioM66] had one to hand, and a door lock that needed automating.

Seeing as grinding pepper requires at least as much torque as turning an average key in an average lock, the electric pepper mill makes perfect sense to use as a lock actuator. This build actually uses the electric pepper mill to directly turn the key in the lock, courtesy of an adapter to couple the square output shaft to the key. The adapter was crafted out of a moldable plastic called MultiMorph. The pepper mill is being used for its high-torque motor & gearbox, which makes it absolutely perfect for this application.

The rest of the project leans heavily on the hacker’s go-to, an Arduino and some off-the-shelf gesture recognition modules. Now, it’s possible to lock and unlock the door at the press of a button or the wave of a hand! Video after the break.

It’s great to see run-of-the-mill objects hacked into useful parts for new projects. In the same vein, check out this car that lets you fistbump to unlock.

Chili-Gation With The MSP430

[Dave] used to grow chili peppers, but after moving to Texas he noticed his plants were drying up and dying off. This is understandable; Texas is freaking hot compared to his old home in the UK. These chilis needed a watering system, and with a pump, relay module, and an MSP430 launchpad, it was pretty easy to put together.

The core of the build is an MSP430 launchpad, a Sharp Memory LCD BoosterPack for the user interface, and a few bits and bobs for pumping water from a large soda bottle to the plant.

Before beginning his build, [Dave] took a look at commercial watering systems, but could only find huge irrigation systems for greenhouses or gardens. This was obviously overkill, but with a few parts – a six volt pump and a relay control board – [Dave] was able to make a simple system that keeps chilis watered for seven days between refilling the reservoir.
