Question: Are you able to make a robot swim

Conor McGinn answered on 10 Mar 2016:

Haven’t tried – but I know its pretty straightfoward to do. What isn’t straightforward is underwater communication and sensing. It takes alot more energy to send messages underwater and a huge number of sensors robots use will not work well underwater also. Another big problem is light. For these reasons – the majority of underwater robots are remote controlled.
There are some really cool underwater robots – here are a few:
