The Aqua2 vehicle is a lightweight and portable amphibious and marine robot. It can operate fully autonomously and it and walk on land, as well as swim.

It can be transported and deployed easily from two standard sized shipping containers that can be transported by commercial aircraft carriers as regular luggage. Equipped with cameras mounted fore and aft and other inertial and environmental sensors, Aqua2 is specifically designed as a research and sensing platform. The robot can be operated as a fully autonomous vehicle without a tether, with a tether for data logging, or as a remotely operated vehicle (ROV) using an operator control unit (OCU).

Main benefits include extreme maneuverability, ROS compatibility, and the ability to easily deploy the robot without the requirement of support vessels. Robots of the Aqua family have been tested to a depth of over 40 m (120 feet), and have an intended operating range from onshore to 35 m (100 feet) deep with or without a tether. Aqua2 is capable of up to five-and-a-half hours of autonomous operation on a single battery charge, based on walking on land (which is more power hungry); swimming is probably feasible for longer. Normal swimming speed is around 2 knots.

There are several different models of the Aqua2-family of robots. The most recent contain Intel i3 CPU's for the main processor, have up to three USB cameras, and can be controlled or programmed over wired, wireless and optical communications.
