7. Name Description Battery LifeThe blimp must operate for at least 40 minutes. Obstacle AwarenessThe blimp must be able to avoid obstacles to prevent damage to itself and its environment. SizeCustom PCB must have the same dimensions as the Raspberry Pi board. Wireless CommunicationThe blimp must communicate wirelessly with a computer via WIFI. Signal ResponsePoint-and-click navigation control must respond to user interactions within 500 milliseconds.

8. [2] SustainabilityReplacementBoth the helium and the LiPo Battery are easily replaceable.
