28BYJ-48-5V Scara Bot

thingiverse

As a small endeavor, I attempted to assemble a SCARA bot with the concept of using it for 3D printing. Although the precision of this robot is commendable, there's an excessive amount of backlash. I've included the inventor files, STL files, a photograph of the functioning project, and the Arduino code that powers the entire operation. Required components for this project: Arduino board with 8 digital pins 4x 28BYJ stepper motors 4x ULN2003 driver boards Some nuts and bolts 4x 623ZZ bearings 4x 608ZZ bearings
