Disney's distant management robots transfer identical to individuals
Think about strolling right into a Disney theme park and being greeted by Mike from Monsters Inc. A life-measurement Mike, completely spherically-proportioned on these spindly legs. Becoming a human into a fancy dress like that’s unimaginable. That is why Disney Analysis is constructing a brand new sort of haptic-suggestions distant management system which can permit us to regulate robots as simply as we transfer ourselves.
The “Hybrid Hydrostatic Transmission” system makes use of each fluid- and air-crammed strains to regulate the actions of a telepresence robotic. By combining the stiffness of fluid strains with the springiness and responsiveness of air-crammed strains, the robotic is ready to transfer in a lifelike method whereas offering fixed, excessive-high quality haptic suggestions. That method, the operator does not go karate-chopping via each floor he touches.
“We now have developed new rotary actuators utilizing rolling-diaphragm cylinders which give excessive torque density,” the Disney Analysis staff wrote, “and permit the creation of a brand new excessive-efficiency 10-DOF humanoid robotic.” Whereas these new actuators are a bit greater and heavier than typical valve-based mostly hydraulic techniques, they do supply very low impedance. Because of this the even greater and heavier motor does not must be mounted on the limb it is powering, which in flip reduces the quantity of energy wanted to maneuver it.
As you’ll be able to see within the video above, the prototype has a pair of arms, every with 4 levels of freedom, and a pair of digital, Kinect eyes that present a reside video feed to a VR headset worn by the distant operator. The robotic itself is designed particularly as a testbed for the haptic suggestions system so do not anticipate to see armies of distant-managed Ewoks rolling via Disneyland within the quick future. However quickly, quickly.
