1961 – Submaray Submersible – Doug Privitt (American)


1961 – Submaray Submersible by Doug Privitt started being built in 1961 and was launched in 1962.


Privitt inside Submaray operating the simple rod manipulator arm. It appears to slide inside a ball-and-socket joint, as can be seen in the video clip. Although a simple setup, this arm is quite efficient and versatile. The claw can be interchanged with other tools and attachments using a quick-attachment feature.
