2013:Shooter Storage Subteam

Shooter/Storage Design

Motor Choice: Selected motor for the storage machine is the am-2235 - Snow Blower Motor - Has adequate rpm, is low profile and has more than enough torque. Motor Characteristics- Frisbee is 1/3 pound = 5oz. 4 frisbees so 4 * 5oz. = 20 oz. Required torque =20oz. * 5.5 in.(point of contact to each frisbee) = 110 oz./in. Indexer speed estimate= 1/4 sec per 1/4 revolution = 60rpm Rule of thumb for rpm is 2 * 60rpm = 120 rpm.

Selected motor for shooter is the Mini-CIM  becuase higher rpm, smaller size and lower complexity than the M7-RS775-18 BaneBots motor.
