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)

Robotic Tool Changers Increase Productivity and Reduce Cost

The ATI Robotic Tool Changer provides the flexibility to automatically change end-effectors or other peripheral tooling. These tool changers are designed to function reliably for millions of cycles at rated load while maintaining extremely high repeatability. For this reason, the ATI Tool Changer has become the number-one tool changer of choice around the world. ATI Tool Changer models cover a wide range of applications, from very small payloads to heavy payload applications requiring significantly large moment capacity.
