Hi ttemple, You are correct in regards to autonomous. The robot can manuever without an ambilical cord of wires. Sensors along with software will guide the robot based on a set of rules allowing it to be used for specific tasks such as tracking oil slicks or other environmental conditions of interest to researchers. Thanks for another great robotics article Ann!
Are flippers more efficient than a propellor? Sea creatures use flippers because they are easier to evolve than a bearing mounted shaft, not because they are the better solution.
A device such as this would be semi-autonomous - it would be able to maintain bouyancy and evade obstacles and non-tech-savvy predators by itself, but it needs to be steered to its' target and told what to do when it gets there (either placing or removing limpet mines, I suppose)
When they say "Autonomous" in reference to robots, to what extent do they mean? I presume that even when they cut the thing loose to swim "autonomously", they still have the ability to take control. Is that the case?
Also, it would seem that autonomous behavior would have to be guided by some set of rules that give the robot some objectives or priorities as to what it is supposed to be doing. Is that the case, or is it just supposed to randomly swim around avoiding obstacles?
Great article. I would be interested to see how efficient each design is at different speeds. In other words, would the turtle design be more power efficient at lower speeds and the tuna design be more power efficient at higher speeds? I would also be curious to see the comparison of each design under different conditions.
Ann, this is great. The number of swimming robots you have described is amazing. This one looks like it could travel large distances, just like real sea turtles. If all these creatures were deployed, we might have to be careful about what we catch when fishing. I am also suprised by the origin of this one and the tuna. Switzerland is a land locked country.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
