Trusters for my first ROV project
Posted: Feb 6th, 2016, 4:34 am
Hello everyone here!
After severall years of silence since i wrote something at the new baby's column, i'm finally starting a ROV build for myself. After a long period of thinking i have dicided to go for bigger build then i had in mind first.
It's going to be about 3 foot long and 2 foot wide and high and will be based on the oceanering type of rov's, such as used for wreck exploratin, just a little smaller.
I have found and bought ten second hand 24 volt brushed, 100 watt, DC motors, which should run about 1400 rpm at max.. I've also found a very useable type propellor from plastic about 6,5 inch diameter from minn kota, type MKP 1. It's a propellor normally used for small super silent elektric fishermen boats.
Also quitte affordable.... just 28 euro's..
After a quick test i soon found out the the propellor runs perfectly under water at just 6 Volts! With no more power consumption as 300 milli app's. Even at 6 volts i have quitte a nice among of trust, so i'm
Actually very pleased with it.. Now the motor and propellor have past the test, i'm going to make a aluminium closed and bio oil filled housing for the first motor. After that i will run some tests again.
For the propulsion of my Rov i'm thinking of using 5 or 6 motors. Two in front, two in the rear, all in a certain angle, for fast and accurate turning, and one or two for vertical trust.
In front i hope to install some sort of gripper (s) for picking up objects....
Because of the bigger motors i need bigger batteries as well, so i think i'm gonna use onboard sealed lead gel batteries.. Don't know yet how to, but i will find a solution for possible risk of gasses and explosion during batterie charging. Not sure of using relais or some sort of electronic motor controlling yet, but first i'm going to focus at the propulsion.
I will post the progress here, greets Robin
Comments are very welcome offcourse
