Payload Subsystem Requirements and
Functional Description
| R2-D2 Head |
We want to mount a head inside the satellite similar to the small one
on R2-D2. It will be able to move up and down as well swivel left and right.
This can accomplished by using the servos in a radio-controlled car. |
| Beeps |
The beeps would mimic the tones that R2-D2 emits. This would involve
supplying power to the audio source. Some ideas for the audio source include
a digital recorder or a small key chain synthesizer. |
| Blinking LEDs |
This payload idea would be a simple set of LEDs that flashes upon user
input or perhaps at random. |
Subsystem Requirements
The payload must meet the following requirements:
- Cool! Neat! Fun! WOW!
- No Fire! Fire! Huh...huh...
- Must fit within the constraints of the spacecraft bus
- Must be powered on by an unplink command signal
- Must be compatible with the power system
- Must weight less than 3 lb
Functional Description
The payload is intended to be the entertainment portion of our program
and should demonstrate the functionality of the other subsystems. The payload(s)
should be designed to fit within the dimensional constraints of the spacecraft
and will proabably be the driving factor in power design and subsystem
layout. To prevent catastrophic failures and to limit danger to the public,
no incindiary devices will be used. A command from the ground station must
initiate payload operation. Finally, to limit mass of the spacecraft, the
mass of the payload must be < 3 lb.
