Fibre-Optical Lightweight Inspection Vehicle


The eROV-300 compiles a robust vehicle chassis with high technology equipment and provides an ideal tool for underwater inspections in even difficult environments.
With this ROV emma technologies GmbH introduces a light-weight platform for multiple survey and inspection tasks under water. Due to its modular design, it is a suitable system base for different applications and can be equipped with high resolution acoustic imagery sonar, full HD camera and LED cluster.
The eROV-300 system data and power transmission is based upon fibre-optical methods. This allows high data rate and bandwidth. Especially for observation purposes the robust fibre optic cable enables disturbance-free real time full HD video and data transmission.

Four thrusters of extremely high lifespans and high torque enable a professional operation and controlled handling, which is also supported by the integrated auto heading and auto depth mode. Low number of revolutions and triple shaft sealings guarantee best performance throughout operation.

Combined with the steering and control module in the ruggedized IP65 version eROCC-VC the eROV-300 can be operated from deck independent on rain or bright sunlight.
