Fancy KTWD ROV

Our funding was cut this year, preventing us from completing the ROV kit project I've been working on since May 2016. Despite successful tank tests, consider these notes before proceeding: program boards prior to connecting motors, coat motor electrical tabs with nail polish to prevent dendritic growth, or have slots plated; the build cost for 30 vehicles is approximately $35 per unit ($1000 USD); plastic parts can be printed on a 3D printer (as I did due to mold expenses); the video shows the vertical thruster disabled, but the code works and has been tested in water and out. When mounting motor clips, ensure prop shafts point towards the vehicle's centerline to avoid interference. Tygon tubing (1/8 ID) is used between props and motor shafts. The microcontrollers are Atmel ATTiny 441 devices, requiring a programmer. Software development was done using Atmel Visual Studio 6.1. PCB files for manufacturing are in the *.zip files under "electrical," and I use a reflow oven for fine-pitch soldering on boards. To size the float, track volumes and weights in the "BouyancyRegister.xlsx" file, and vapor treat floats for optimal performance at depth.
