Abstract:

A submersible device according to an embodiment of the invention includes a container configured to be selectively buoyant in a liquid. The container can have at least one of a variety of different buoyancy systems. For example, the container can include a reservoir where the volume can be adjusted. In another example, the container can include a reservoir in communication with a pump configured to control the intaking and expelling of a liquid. In another embodiment, the container also defines a first partitioned section and a second partitioned section. The first partitioned section is substantially liquid resistant and the second partitioned section defines a hole in communication with an exterior of the container. An actuator is configured to receive an input from a user and is configured to modify an interior volume of the second partitioned section based on the input.
