20230531 Design Review with Jesus

Weight savings

With the removal of this material from the design we reduce the weight of the enclosure by almost half from 12.078 lbs to 7.8763125 lbs

Saw that we could utilize a penetrator with a larger inner diameter if concerned about the cables not fitting within the penetrator

Current penetrator modeled in is for a 4.5 mm diameter I'D. We can utilize a 8mm I'D penetrator if we are concerned for space 

Cable clearance with the penetrator with a 8mm ID 

Alternate placement of the DVL placement to save on the wire lengths for for connecting up to the dvl

Talked about the combining the battery clamps to fit the clamps in between the thrusters but not need to make the frame wider for the thrusters to integrate well. However the battery tubes will will be below the thrusters.

Check design against the design guide. Holes for mounting of the enclosure plate are 0.109 in diameter and 0.5 inch depth. 

Threaded portion is 0.25 inches which is slightly larger than the guideline of length < 2*1.09 guideline.

Can remove the extra material t o reduce the thickness of the wall

Looking back the above assumptions that that thread

Not ideal configuration with the ports upward as the water from the enclosure and end cap can drip down into the enclosure

Layout of battery tubes in addition to the dvl enclosure at the bottom of the frame. Notice how the vertical thrusters are slightly obscured by the battery tubes

20230523 Test Fitting Design

 

Dovetail designs were implemented into the design to enable manufacturing on the 256 mm x 256 mm by 256 mm build volume of Bambu-X1 Carbons.

Test fitting the electronics within the enclosure. All of the electronics fit the wire bend radius have been verified

20230517 Edit geometry for new 4 inch chevrons

 Chevrons are now 4x4 instead of 6x6 so the gripper claw geometries need to be updated accordingly.
