Mechanical Overview

BumbleBee’s mechanical structure is mainly made up of 2 piece aluminium, the frame and the hull. The hull houses our electronics and forward camera while the frame serves as the intermediary structure to hold the thrusters, compressed air tank, hydrophones, DVL, downward camera, manipulators.  All nuts and bolts on the hull and frame are made out of stainless steel.

Aluminium Hull

Hull1

  • Strong
  • Light
  • Resist corrosion
  • Good thermal conductivity

C-Channel Frame

Frame 

  • Welded together to maintain rigidity
  • Perforated with rectangular holes
  • allow flexibility in component mounting positions

 

Polycarbonate Front        Visual check on electronics w/o breaking seal
Supporting Flanges
  • Ribbed to give additional strength
  • Punch pattern for weight optimization

 

Dovetail O-Ring Flange Seal Design
  • Secure placement of o-ring
  • Allow convenient removal of end cap
  • Increased sealing pressure with depth
