Hi all
as many of you are probably aware, Crown of Thorns Starfish are a serious problem on the Great Barrier Reef.The current main method of control is to have divers inject them to kill them which is a role that could well be better fulfilled by an ROV. I have made a prototype injector to attach onto a BR2. it is based on a Newton gripper as an actuator pushing the plunger on a livestock drench gun so the cost is relatively low.
If anybody is interested in navigating through a very opaque beauracratic process to try to get funding to deploy units with these injectors on them, they are welcome to the CAD files I made for 3d printed parts and alloy brackets for rigidity. Contact me for a video of it and files.
