SEABOTIX
LITTLE BENTHIC CRAWLER
ROV
GENERAL DESCRIPTION
SeaBotix has developed a revolutionary new product that combines the proven
technology and performance of the LBV with the ability to strongly adhere to any
hard surface in any orientation. Once attached to the hard surface the LBC utilizes
four-wheel drive and large knobby tires. This ability provides unmatched stability beyond
conventional ROVs.
Overview
The initial LBC was an all in one ROV/Crawler. Extensive testing, demonstrations and
feedback have resulted in a Convertible type system. In its standard form the LBC is a
fully capable MiniROV system offering all the capabilities of the LBV type systems. When
conditions exceed the capability of ROV mode or more precise control is required simply
attach the crawler skid and adhere to the hard surface.
This unique combination of ROV and Crawler capability makes LBC an incredibly well
rounded and capable system. Consider when operating an ROV for ship hull inspections,
unless conditions are ideal, the task can be challenging. Current ow can often make
maintaining a stable position for accurate object identication difcult. Add turbid
or black water conditions and the difculty escalates. Additionally, once an object is
located precisely identifying the object and its position on the ship hull have their own
challenges.
The concept of creating a crawler that attaches to the ship hull helps to reduce and even
eliminate the difculties encountered. There are two primary inspection methods for the
LBC.
ROV MODE (3D) - the LBC operates as a free ying ROV in ROV MODE without
the crawler skid attached. This mode enables the operator to freely inspect various
structures through traditional ROV operation. The LBC with crawler skid attached can
also operate in ROV mode, however, slightly increased weight, drag and centralized
Center of Gravity due alter performance.
CRAWLER MODE (2D) - should conditions hinder the ability to maintain a stable
position and accurately acquire the required video and data the LBC can quickly be tted
with the Crawler skid (less than 5 minutes). By switching to CRAWLER MODE the LBC
can attach to the hard surface eliminating unstable movement allowing the operator to
conduct precise inspections. This attachment is possible by rolling the LBC and turning
on the suction device.
The LBC offers the ultimate in diversied inspection capabilities as a result of the
standard features.
