 Brian,I can help anyone build this, but I rarely draw things like this.  I take an idea and a bunch of parts and go for it.Hank

 Hank,what are the advantages of the linear actuators over a hydraulic manipulator.Is it just smoothness of control? No large valves?  If you have to have hoses to the actuator for compensation, which you would have for hydraulics anyway, thenis there much more of an advantage. You would need to find a linear actuator witha stainless piston rod.I am wanting to build a manipulator but still vacillating over the various options!Cheers Alan

 Alan,It was a shallow dive to get the sub balanced and ready for a job I have coming up.  I had to make proper electric penetrators to keep the oil in.  I also had to add an expansion bladder.Hank

 Hi Hank,
See on Facebook you have been diving!
Wondering what modifications you had to do on your electric arm.
How deep did you go etc.
Alan
