My first ROV: ROVTNIK V1

[MarcoMota]

Here are some pics of my first ROV that I named ROVTNIK. The ROV is based from one of the ROVs showed in the book: Build Your Own Underwater Robot and other wet projects by Harry Bohm and Vickie Jensen.

To make it I used brushed motors sealed with wax. The control box/wiring was also sealed with wax. The wire was two RCA connectors; one wire was the ground, the other 3 were used for powering the 3 motors unidirectionally. The power was given from the surface with 7.2V NI-MH battery. Poliester was used to make it float. Iron pieces where used to make it bottom heavy. PVC pipes where used for the structure. The hollowed base was a plastic vegetable box that I cutted for my needs.

It was positively buoyant.

It had no camera.
