REx II is Back in Cambridge

Today, we got the REx II vehicle back from Hawaii.

Due to restrictions on shipping, we didn't bother to send the lithium ion battery by mail. Instead, we just built a new one.


Unlike the battery for Odyssey IV, this battery is designed to fit into the bottom half of a pressure tube. The individual supercells are not wrapped in plastic, but instead squished together to form the full battery.


The electronics fit on top.

Highlights of Rex2 Footage

Dylan is working with the Reef Explorer 2 (Rex2) in Hawaii. He just posted this video of some of the best recorded footage.

There were quite a few sea turtles curious enough to swim up to the vehicle.
