AC-ROV. (Possibly the best small Rov in the market).

The smallest inspection class ROV in the market place (190mm fly through). The AC-ROV is more powerful, more robust and a more cost effective solution than all other ROVs in its class.
These facts however are secondary to the real capability of the AC-ROV. All underwater ROVs have a flight pattern that reflects the movement of an aeroplane (3 degrees of movement) - this means that when inspecting or observing a target the ROV must constantly move in and then away to take up a fresh viewing position. The AC-ROV however has the underwater flight pattern of a helicopter - this allows the ROV to hover, circle, rotate on its axis and move in any direction the target requires. This breakthrough is achieved by six internally housed thrusters that produce five degrees of movement.
With an operating depth of 75-100m, a total system carry case weight of under 15kg, and a service life of 200-300 hours at 100% duty (continuous full depth & full speed), the AC-ROV has been designed for inspection in hazardous and confined areas.

The AC-ROV has a two- function manipulator (option). The manipulator combines grip and full continuous wrist rotate via a ground breaking drive-train, resulting in the smallest two-function manipulator in the ROV market. Consisting of titanium, aluminium, stainless steel and plastic components, the AC-ROV micro-manipulator system comes completely integrated into its own bottom buoyancy block. There are no underwater cable connections thus limiting snagging potential, while the integrated nature of manipulator and block gives the system inherent strength and robustness - a feature demonstrated by all AC-ROV components. Simply remove the standard bottom block from your AC-ROV and fit the manipulator block, the manipulator is 100% interchangeable between individual AC-ROV units, giving maximum functionality and cost savings. Topside control is a thumb activated one handed joystick controller that simply connects directly to the control box without need for modification, with all manipulator operations viewed via the state of the art camera system. Two and three jaw options are available and customers can specify special gripper heads for specific jobs. Three screws secure the jaw assembly to the arm and change-out could not be easier.

Notes:
1. Flight assist controls include; Flight Freeze & Un-freeze / Progressive +/- Vertical Trim / Progressive +/- Pitch / 3 stage Power Increment. All these functions are programmed on the hand controller. Light dimmers are incorporated on the control box.
2. The AC-ROV thruster does not have a centre and the inward pointing blades do not meet. The full-bore unrestricted flow path maximises thrust and is relatively self-clearing in weed type environments.
3. The tether cable and connectors are field serviceable, given that the operator has basic electrician skills. Any damaged cable can be cut out and any remaining serviceable cable re-terminated and used again without the need for specialist cable moulding services.
4. Connect a PC or Laptop computer with video grabber, or a video recorder for video recording and data logging.

A computer is not required for normal operation nor included in the supply.
