Man-Portable Active Protection System (MPAPS)

Design has been reworked to implement more clearance for wires to and from Arduino in the base, a bearing system integrated into the print itself that reduces spacing between the base and turntable, and more clearance for wires running from base to turntable motor and turret laser/launcher.

Additionally, motionDetect.py has been created which utilizes a real-time motion extraction filter paired with contour detection using the OpenCV package.

Built prototype test-bed with components:

• Arduino Uno R3
• 2x Nema 17 stepper motors
• 2x TB6600 stepper motor drivers
• custom built circuit board

Working with MPAPS_movement.ino test code that implements degree based aiming commands while keeping track of origin and orientation w.r.t it.

Ran into issues driving the turntable as the lazy susan bearing requires too much spacing from the base for the NEMA 17 to directly interface with the turntable. This necessitated extending the motor shaft with a shaft collar and 5mm aluminum rod, however this proved to be unstable and would work itself loose over time.

Reworked the initial CAD files to include accurate mounting points for NEMA 17's, Lazy Suzan bearing, Arduino Uno, and 10mm bearing
