L3–37 Droid from Solo Recreated as an Amazon Alexa

Whether you’ve seen the newest Star Wars iteration or not, you’ve certainly noticed a fun-looking droid with green accents on its head that apparently is there to give Lando coordinated salutes. Yes, this new droid is named L3–37, and as seen here, “PatchBOTS” decided to duplicate its — or her, judging by voice inflection — head with Amazon Voice Service abilities.

So while this droid might not be able to do normal “droidish” things like roll around and hack into Imperial computers, it can at least answer voice queries. Originally, the plan was to use an Actual Amazon Echo Dot, but since he wanted to use “L3” as a wake word, he instead installed an Amazon Voice Service SDK on a Raspberry Pi. In addition to wake word customization, this also allowed him to set it up for a female British accent to more closely match the movie’s L3. It also meant that he can take advantage of the Pi’s GPIO functionality, and an Arduino Nano is also added to help control everything.

Now when L3 is triggered by saying “L3,” it springs to life, raising its head via a servo motor, and shining onboard lights. You can see it in action along with more of the build process in the video below, while the code and 3D files are available on GitHub if you’d like to create your own. One cool “feature” is that because L3 has a jumble of wires hanging out, you don’t even have to worry about keeping this tidy!
