Mechanical Targets Size

Fits in a 72x36x36 in Box Currently about 35x15x15

Weight Must be under 120 pounds

Aiming for 40 pounds Actions

Drop a Marker Shoot a projectile 5 feet Grasp object from below 3 planes of Thrust Knock a pipe off pegboard

Positioning Cameras down and forward

In-line with torpedoes and droppers Separate battery pod Compass away from magnetic

interference

Features Easy access to electronics Watertight enclosure Even and minimal drag Dynamically and statically

stable Very configurable Slightly positive buoyancy Convenient carrying by two

people Crane hooks Heat mitigation Condensation and leak

mitigation External switches

What We Need To Know NowMini Computer

Are we going to use one or not?Hydrophone

What are your ideas for Circuit Boards?Size and appearance of the hydrophone

droppers?Is there a location that you would want to see

us place them?

Questions For YouIs there a certain location that you see

specific circuits needing to be placed?On the circuit rack for your ease of use

Out of our Mechanical Targets:Are there any more that you see us needing to

account for?Do you have an accurate file for the Marker
