So, I have been given an excuse to source some photos of Fiddler Crabs, just because some students were surprised that the claws of Navi Robo were a different colour from the rest of its body. Of course, these crabs are using their claws to send very different messages from the robot, but it is nonetheless of great importance that they attract attention, hence the large size and sometimes very bright colour of their signaling claw.
There, that’s enough wildlife for now, back to robots next time.
