The miniature forklift was a group project I was part of while taking a CAD class at the Santa Rosa Junior College . My group had about 8 weeks to design and build some type of project that demonstrated our design skills, and we chose to build a miniature electric forklift.
Our goal was to have a finished prototype that could drive forward and backwards, turn, and lift an object weighing at least 5 lbs. We used an arduino, three DC motors, a battery, and three H-bridge motor controllers all controlled by a custom 3D printed controller connected through a cable.
My role in the group was to design and build the steel frame, the lifting mechanism, and the wheel hubs.
Here are drawings I created for the two frame elements: the main forklift body and the lifting mechanism. After completing the design step, I cut, milled, welded, and painted the frame components.
I also made a miniature pallet for testing the forklift:
Here is a video of us testing the completed forklift:
