Edible art from a Robot Pancake Printer

In case you didn’t know it, pancake art is a thing. People are turning out incredible edible artwork using squeeze bottles and pancake batter. But even if you’re not terribly artistic, you can still amaze your breakfast buddies with this robotic pancake printer.

At its simplest – and in our opinion its most impressive – pancake art involves making patterns with thin batter on a hot griddle. The longer the batter is cooked, the darker it becomes, and art happens. To capitalize on this, [Trent], [Kevin], [Sunny] and [Isaac] built a 2-axis gantry with a working area the size of an electric griddle. A bottle is pressurized with a small air pump and controlled by a solenoid valve to serve as a batter extruder, and an Arduino controls everything. Custom pancake design software lets you plan your next masterpiece before committing it to batter.

Sadly, the video below shows us that the team didn’t include an automatic flipper for the pancake, but no matter – that’ll make a great feature for the next version. Maybe something like this?

Robottermilk Pancakes

With a name like that how could we possibly pass up featuring this one? Truly a hack, this pancake making robot was built in under 24 hours. [Carter Hurd], [Ryan Niemo], and [David Frank] won the 2015 Ohio State University Makethon with the project.

The gantry runs on drawer sliders using belts from a RepRap. The motors themselves are DC with encoders. [Carter] tells us that since most 3D Printers are build on stepper motors this meant they had to scratch-build the control software but luckily were able to reuse PID software for the rest. Get this, the pump driving the pancake batter was pulled from a Keurig and a servo motor is used to kink the tubing, halting the flow. We are amused by the use of a Sriracha bottle as the nozzle.

It wasn’t just the printer being hacked together. The team also built an iPhone app that lets you draw your desired pattern and push it to the machine via WiFi.

Inspired yet? We are! If you’re anywhere near New York City you need to bring this kind of game to our Hackathon on May 2-3. One night, lots of fun, lots of food, and plenty of hardware. What can you accomplish?

Flipping pancakes

[Petar and Sylvain] are teaching this robot to flip pancakes. It starts with some kinesthetic learning; a human operator moves the robot arm to flip a pancake while the robot records the motion. Next, motion tracking is used so that the robot can improve during its learning process. It eventually gets the hang of it, as you can see after the break, but we wonder how this will work with real batter. This is a simulated pancake so the weight and amount at of force necessary to unstick it from the pan is always the same. Still, we loved the robotic pizza maker and if they get this to work it’ll earn a special place in our hearts.
