Selecting Motors/gear ratios
Desired specs: 180 deg/s speed, 180 deg/s^2 acceleration
Argos 3.0 motors: 16kgf-cm (13.89lb-in), 122rpm
Moments of inertia:
Pan:
Tilt: 6.99 ~ 7.00 lb-in^2
Gear ratio: Ia/Tm < Gear ratio < (122rpm*6deg/s) / (180deg/s)
Pan: I*pi/ 13.89 = < Gear ratio < 4.06
Tilt: 7*pi/ 13.89 = 1.58 < Gear ratio < 4.06
Push Rod system
Push Rod system
We decided to use a dual pushrod system, as it allows for much more precise control of the tilt angle
This system will use two motors to control opposite directions
