Crawler Skid - How it Works

The LBV150SE-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 LBV150SE-5 with crawler skid is intuitive to operate in all modes.

ROV Mode
When in ROV mode (default) the LBV150SE-5 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 LBV150SE-5 easily transitions to facilitate attachment to the surface (such as a ship hull). To attach to a hard surface the operator pilots the LBV150SE-5 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 LBV150SE-5 into a roll. Once the angle of the LBV150SE-5 matches the angle of the ship hull the operator turns on the attractor which in turn sucks the LBV150SE-5 to the ship hull. Once attached the operator can release controls with the LBV150SE-5 staying firmly in position.

Crawler Mode
With the LBV150SE-5 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 LBV150SE-5 can tackle various obstacles and has a maximum speed of 30 m/min (100 ft/min).

Vortex VRAM
The Vortex VRAM makes the LBV150SE-5 possible. With the patented design the VRAM produces a vortex effect creating a strong 28 kgf (62 ft/lbs) 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.
