RangerBot is an advanced version of the 2015 robot, with a newer submersible design, handheld remote-control and computer vision to identify invasive species.

"In 2015, an early prototype of the robot "COTSbot" made international news. Now its successor the RangerBot is significantly more advanced.

The RangerBot is equipped with a vision system that allows it to "see" underwater while being operated using a tablet.

QUT Professor Matt Dunbabin said the robot used real-time vision to navigate and identify starfish."
