The 12788 robot needed an intake system, but we had prioritized other design tasks for the first part of the year. In the week before winter break, I created this design as a potential solution. While we ultimately chose a different design, I am still very proud of the spatial efficiency of this design. It had to fully fold into a 9" x 3.5" space while also being capable of folding out to accommodate 4" x 8" blocks. It took many scrapped redesigns to package the motors and other mechanical components in a secure and functional way while preserving functionality, but the end result was a model that would have worked if constructed.
