Custom Designed and Built ROVs and ROV Mounted Tools

  • Downdeepdrones focuses on designing and building ROVs or Underwater Drones with custom tools mounted on them almost exclusively for solving marine environmental problems. 
  • Known for innovative first of a kind designs, we have a history of fifteen years of tackling some of the biggest marine environmental problems such Marine Debris Collection, Crown of Thorns Starfish Eradication, Invasive Sea Urchin Culling and an Underwater Drone mounted Speargun allowing for selective targeting of a fish with no bycatch and a very low carbon footprint.
  • If you have a project that benefits the planets environments, let us know what you have in mind and we can see how we can help you. 
  • Any revenue derived from the services provided goes directly back into research and development of better and better designs and products. 
  • All designs of custom ROVs apart from the QYSEA underwater drones that show custom tools mounted on them is the sole work of myself.
