AMPHIBIOUS ROBOTIC CRAWLER

An amphibious robotic crawler for traversing a body of water having two frame units coupled end-to-end or in tandem by an actuated linkage arm. Each frame unit includes a housing with a drivable continuous track rotatably supported thereon. The frame units are operable with a power supply, a drive mechanism and a control module. Each frame unit further includes a buoyancy control element for suspending the frame unit in the water, and for controlling the depth of the robotic crawler within the water. The control module coordinates the rotation of the continuous tracks, the position of the linkage arm and the buoyancy of the buoyancy control elements to control movement, direction and pose of the robotic crawler through the body of water.
