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

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
