Jetson Nano ready for tank testing
By Aaron Marburg
The student testing in March was the maiden voyage for our Jetson Nano-based ROV odometery package. The Nano barely fits in a 4" Blue Robotics tube – we’re using the older non-locking housings which let us cut the acrylic tube to a custom length.
The uplink connection is BlueRobotics ethernet+power cable through a Wetlink bulkhead.
When we install it on the BlueROV, this cable will go into the main housing, where we’ll install a BotBlox switch.
I wanted to be able to test the system without a BlueROV, so I’ve added a small 2" housing which acts as a jumper to a longer stretch of wet cabling. The 2" housing also contains a BotBlox switch. To move the system to the ROV, we disconnect the ethernet from the switch and disconnect a power connector, then unscrew the bulkhead from the 2" housing and install it into the BlueROV. The two connectors inside the 2" housing (Molex Picoblade for the ethernet and Microfit for power) both fit through the 10mm hole in the endcap, so we can swap without modifying the cables.
