Project Constraints

Tetrahedral Array Constraints

• Array must have tetrahedral geometry

• Must be able to adapt to NASA RDS

• Tetrahedral array cannot interfere with any existing sensors other than the omni-directional camera

• All microphones must be orientated upward and lie in the horizontal plane

• When collapsed, the array must not protrude outside the overall footprint of the RDS

• Overall height of the tetrahedral array must add no more than 25% to the existing robot height

• Microphones must be spaced 20 inches apart

• Must be remotely collapsible

• Must dampen mechanical vibrations

• Low Cost

• Lightweight

• Components must be off-the-shelf

T-Base Array Constraints

• Must be able to adapt to VEX robot

• All microphones must face upward and lie in the horizontal plane

• Must be able to dampen mechanical vibrations

• Microphones must be spaced 10 inches apart

• Lightweight

• Low-Cost

• Use as many off-the-shelf components as possible
