Pan Axis

• Continuous panning will be achieved via a through hole BLDC motor (https://store.tmotor.com/goods.php?id=1126)

• Pan position will be kept track of by using an absolute encoder (https://www.rls.si/eng/orbis-true-absolute-rotary-encoder?partNumbers=BR20PWA14B22DD00%2CBA200AB03AA00)

• Wiring above the pan axis will pass through a slip ring capable of USB 3.0 transmission (https://www.directindustry.com/prod/ceno-electronics-technology-co-ltd/product-204613-2242299.html)

Pitch Axis

• Pitch axis will be controlled via a standard Hitec servo motor (https://www.robotshop.com/en/hitec-hs-422-servo-motor.html

Camera

• Camera will be a Stereolabs ZED2 camera (https://store.stereolabs.com/products/zed-2)

Design Review Notes (7/1/2021):

• Confirm slip ring stuff

• Look for approximately 7/8 threads of engagement

• Use pem or rivet nuts (pem by Austin, Tony says rivet nuts)

• Add rubber vibration dampers

• Talk with machine metal fabricator to make sure alignment is good

• Flaring of the flange (ask machine shop about that) wider also makes it stiffer

• 5052 Aluminum

• Add loops for wires, and zip ties for camera mount

• Laser cutting aluminum vs steel

• Preload the righthand joint

• Dust issues with the PCB (encoders)

• Check with electrical on encoder config needed
