Planning

To do for Subsystems Checkoff:
- figure out drive train details
- obtain and try out omnidirectional wheels
- build arm prototype & attach, figure out actuator
- sorter (ball handling, ball sensing, ball differentiating)

Need to buy:
spring hinge
2 drive motors
shielded wire
microswitches
roller
actuator?

Notes:
- we can leave the shooter motors on constantly, even after the 2 minutes are up; so says ruddick.
