Automated Loading and Imaging of Microtiter plates
*Rendered Image of the Designed Machine*
Background
This project involves designing an automated system to transfer microtiter plates from multiple racks into an imaging device, which will then capture images of the wells on each plate.

The racks that are powered by a DC brush motor start moving towards the arm
The first rack stops when a laser beam sensor with reflectors align with the beginning and end of the rack
The same process repeats until 50 plates on 10 racks are complete
