Increased stability in demanding conditions
The LBC's unique vortex suction device enables it to adhere strongly to the surface being inspected in currents up to 5 knots. Even in such difficult conditions the LBC provides a stable sensor platform for high quality data acquisition. Don't be fooled by imitations!


Simplistic operation for all operators

Attachment to a ship hull is incredibly simple and mastered by many in a few minutes. The dual vertical thruster configuration allows for the operator to roll the LBC and attach to the ship hull. The LBC then provides video/sensor feedback in a normal attitude further simplifying operation.


Ultimate in versatility

The LBC is comprised of the Crawler Skid Attachment (CSA) and the LBV300-5 system. Operators have a fully functional MiniROV system found in the LBV300-5 and the ability to add the CSA when required in only minutes. No other system offers the versatility and capability.


Four wheel drive
Once the LBC is attached to a ship hull it uses a four wheel drive system rather than thrusters. This method increases the operating capability with incredibly amounts of torque. Four wheel drive ensures traction and straight line tracking during inspections.


Patented vortex suction device
Part of the LBC is the unique and highly patented Vortex suction device. Use of the Vortex creates an amazing amount of attraction (23 kgf) in a low profile device. The Vortex is more efficient and effective than thrusters, plus it works on any hard material unlike magnetic systems.


Unmatched sensor data acquisition
With it's ability to stay in one position indefinitely the LBC can acquire data unlike a free swimming ROV. Sonar, NDT and video are very precise as the LBC maintains its fixed or steady position.

The LBV300-5 with crawler skid represents the ultimate in versatility with the ability to conduct traditional ROV inspections as well as crawler inspections. In following SeaBotix standards the LBV300-5 with crawler skid is intuitive to operate in all modes.

LBC AnimationROV Mode
When in ROV mode (default) the LBC operates much the same as the traditional LBV. The intuitive hand controller provides all controls in one simple to use, ergonomically designed controller. Operators are able to conduct diverse types of free swimming ROV inspections such as harbors, wharfs, ship hull components, etc. Utilizing the core components from the LBV provide added features such as powerful thrusters, auto functions, 270º field of view, information overlay and more greatly easing inspection tasks.

Attach Mode
When inspections warrant the attachment to a hard surface the LBC easily transitions to facilitate attachment to the surface (such as a ship hull). To attach to a hard surface the operator pilots the LBC close to the ship hull positioning either the port or starboard wheel set close to the hull. Using the lateral function on the joystick the operator initiates the LBC into a roll. Once the angle of the LBC matches the angle of the ship hull the operator turns on the attractor which in turn sucks the LBC to the ship hull. Once attached the operator can release controls with the LBC staying firmly in position.

Crawler Mode
With the LBC attached to the ship hull or other hard surface it can be driven rather than flown. The operator simply switches controls from ROV mode to Crawler mode which disables the horizontal thrusters and enables the powerful drive mechanism. With four wheel drive and lots of torque the LBC can tackle various obstacles and has a maximum speed of 30 m/min (100 ft/min).

Vortex VRAM
The Vortex VRAM makes the LBC possible. With the patented design the VRAM produces a vortex effect creating a strong 23 kg f (50.7 pd f) of attraction. The incredibly small form factor has many benefits over larger less efficient ducted props and especially magnetic attractors. Magnetic attractors suffer from requiring the surface to be ferrous metal and relatively smooth due to the close proximity of the magnetic attractor. The VRAM can be spaced away from the surface allowing greater ground clearance while still maintaining a solid attachment
