Fields of activity

Collaboration on the development of a hybrid diving robot (H-ROV)

  • Concept development of the control system
  • Integration of pressure-neutral drive and energy supply components from Enitech:
    Reprogramming of the firmware for the drives and the battery monitoring system
  • Design and implementation of the control software based on the communication middleware Orocos and the Robotic Construction Kit Rock.
  • Porting the software to the Robot Operation System(ROS)
  • Development of a universal, configurable graphical user interface (GUI)

Further development and operation of autonomous underwater vehicles (AUV)

  • Integration of an EM2040 multibeam echosounder into the control software
  • Integration of a Benthos SIS1624 sidescan sonar into the control software
  • Integration of an IXBlue Echoes 3000 subbottom profiler
  • Development of auxiliary programs for data analysis and visualization
  • Operation of the device on numerous expeditions

Hardware development for various projects

  • Control system for sediment traps
  • Autonomous time-controlled data logger for scanning sonars, e.g. for use in moorings
  • Device-side control for the MeBo70 seabed drill rig
  • 16MPixel particle camera using a digital medium format camera back
  • Control system for the wheel-driven vehicle MOVE!
  • Sound transmission for the seabed drill rigs

Software development

  • Participation in the development of the control software for H-ROV, AUV, MOVE! and MeBo70 and MeBo200
  • Firmware for the self-developed hardware
  • Various programs and tools
    - Data visualization
    - Conversion of sonar data
    - Display of sensor data
    - Conversion and forwarding of navigation data
