Current Design
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
