Sorting bricks by color is a demeaning task that even a robot could do, so we built one!
Our machine reduces exposure to the germ-harboring bricks, thus keeping the employees healthier.
With our machine, each LEGOLand could save over a thousand dollars a month!

After hours of sorting bricks at LEGOLand Discovery Center, I can finally design and build the robot to steal my job!
For this project, Raquel used her networking magic to talk to two different Master Model Builders! Her learning goals were to stay on brand and create a polished final product.
Katie is originally from Michigan and spends most of her time making potentially autonomous boats, playing board games, and listening to musicals. Katie is the proud owner a LEGO table and over 30 pounds of LEGO bricks.
As part of LEGpOe, she mainly worked on mechanical design, CAD, and documenting Eric’s quotes. Her learning goals for this project were: designing for integration and creating a modular system.
Eric’s first LEGOs were a box of mismatched bricks that came from a yard sale when he was five. His other interests, in no particular order, include bees, history, his dog, sci-fi and fantasy, tea, maps, Vermont, and music.
As part of LEGpOe, he’s been doing a lot of mechanical design and has been improving his CAD skills through 3D printing all the plastic parts of the LEGO Sorter machine.
Serna is originally from South Texas and is now permanently cold. Growing up she loved to build Star Wars Lego sets with her older brother.
For the project, she worked on making CAD models and laser cutting. She was also very excited to include finger joints in her designs!
Anna loves the outdoors and never turns down an opportunity to go hiking or biking. She cares about sustainability and ironically remembers her gas station LEGO set most distinctly.
Anna has been leading the software side of this project. She worked with OpenCV and Arduino and has learned a lot about integration.
