Robotic Drawing!

This repository is an interactive robotic drawing installation for Kids at Autodesk Day 2017, by @nonoesp and @garciadelcastillo.

A touchscreen allows kids to draw their creations, and a series of scripts convert their designs to robotic instructions.

The project is built with Machina for DynamoBIM and Processing.

Special thanks to Nono for teaming up to put this together, Lilli Smith from the Generative Design Team for the organization of Kids' Day, and the incredible team at the BUILD Space, including Joe, Salem, Tim and the rest of the dream team ;)

Setup

If you want to try this at home (or probably better, your robot-enabled shop), please do the following:

• Install Processing and Dynamo Studio in your Windows machine.

• Inside of Dynamo, you should install two packages from the Package Manager. Go to Packages > Search for a package... and install JsonData and Machina. If at the time of this reading the packages have updated and broken some functionality, you can find copies of the working packages with this project in the folder 01_dynamo_packages.

• Go to 02_processing_sketch and open it with Processing. When you run it, you should see a full screen window where you can draw with your fingers or mouse. It also has some buttons that allow you to start a new drawing, undo some actions or export the current drawing. As you hit Export, two .json and .jpg files will be saved to the data folder in the sketch with the bitmap drawing and the json representation of the strokes.

• Go to 03_dynamo_script and open the Dynamo file with Dynamo Studio. On the far left of the screen, there is a code block with drawing parameters that you can customize based on your screen resolution, paper dimensions, location and orientation of the paper in robot world coordinates, and some speed settings.

• Once the settings are customized, load the .json file exported by Processing into the script with the File Path loader. If everything goes well, you should see planes representing the planes of your drawing in the 3D view. If that is the case, a .prg file will be saved to the dynamo script folder with the offline program that can be loaded in the robot controller and ran to draw the strokes ;)

The installation has been designed and tested for an ABB IRB 120 robot, but ideally, with small changes in the Machina script, it could be used for Kuka, Universal Robots, GCode, etc.

Have fun!
