Mounting the Propellers
Mounting the Propellers
What should we consider when mounting the propeller?• How will propeller placement effect
speed/maneuverability?
• Where on the ROV?
• Close together? Far apart?
• In frame? Out of frame?
Mounting the Propellers
• 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?
