Robot Octopus Takes to the Sea

From Evan Ackerman at IEEE Spectrum:

The video below has four parts to it: the first shows the difference between the robotic octopus swimming with just flexible arms, and swimming with just flexible arms in addition to a web. The most obvious difference is the speed: just over 100 millimeters per second with arms only, and up to 180 mm/s (or 0.5 body lengths per second) with the web. This is a significant increase, obviously, but what's more important is the overall cost of transport (CoT), which is a measure of the efficiency of the robot (specifically, the ratio of the energy put in over the resulting speed). The CoT for the arms-only version is 0.85, whereas the web drops that down to 0.62. So yeah, having that web in there is better in almost every way... (cont'd)

ST Robotics - r12 robot arm

ST Robotics have decades of experience in industrial robots having sold hundreds of robots over the years. The company has 3 main models, R12, R17 and R19 all using a unique simple industrial technology that dramatically reduces costs resulting in the lowest priced industrial robots available. The same uncomplicated technology vastly improves reliability. ST backs this up with a 2 year warranty. Typical applications are routine testing, sample handling and also education. The software is a different paradigm from most robots. It is command based; you type a command and see immediate action. Programming is a building block approach, building confidence as you program in small 'mind-sized bytes'. ST offers free unlimited technical support.
