As seen on Reddit, the Vomit Comic Robot is not only able to spew words out of its thermal printer mouth, but generates actual pictorial comics via a Processing sketch running on a Raspberry Pi. A simple user interface consists of a button on top, which causes the robot to expel, along with several lights and a “halt”— power off — button in the back.
The robot itself is quite well made, first mocked up with foam core and masking tape, then finally laser-cut out of birch plywood, using Ponoko to do the actual manufacturing. In order to create a robotic effect worthy of its vomitous comics, the wood was stained using clothing dye and decorated further with coffee grounds, also with a marker transfer technique using a toner-based print.
As with many projects, fitting the electronics inside presented quite the challenge (no one ever asks for a smaller enclosure), but worked out in the end. If you’d like to build your own, code for the project can be found on GitHub.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
