[PSUBS-MAILIST] Manipulator Build

[Alan via Personal_Submersibles]

Have made a start at making a simple light weight electric manipulator.
I need a wide range of movement to be able to use it to cut away any obstruction from the thrusters & also to use it as a periscope & camera gimble. ( oh yeah & pick up things) So am opting to go with electric motors powering gears on the joints instead
of more robust pistons.
2 modified power window openers arrived this morning from Cytron Robotics.
I wanted to see if they were suitable for modifying for use without any sealing
or compensation. Pulled one apart as per picture but it isn't that suitable.
It is pretty simple with the worm gear directly on the motor shaft & a 65-1 ratio
with the large plastic gear.
Looks like the nephews are getting a robot for Christmas.
It is a start & has given me a few clues as to how to clone it out of non corrosive
parts & with the use of the resin sealed motors I picked up from Blue Robotics
nothing will need to be fully enclosed or compensated.
