speed/maneuverability?

• Where on the ROV?

• Close together? Far apart?

• In frame? Out of frame?

• Attach propeller to ROV

• Two propellers will be up and down• Two propellers will be

forwards/backwards/right/left

• Where on the frame?• Which direction will it

face?• Is there anything

obstructing its view?• How do we attach it?
