I've
said before that certain experiments are a veritable cri de coeur for
an Ig Nobel prize, the awards that honor silly but thoughtful
science.Well, Cornell University graduate student Ashesh Jain and
colleagues should be in the running for their bold attempts to teach
robotic grocery store clerks of the future how to handle knives so they
don't terrify human customers.Their study, "Learning Trajectory
Preferences for Manipulators via Iterative Improvement," sounds
innocuous enough until you see the humanoid robot with a large blade in
its gripper. This takes robot-knife experiments to a new level.Rethink
Robotics' Baxter assembly robot was designed to work in close quarters
with humans, but as seen in the demo below, its knife gets a little too
close for comfort.Google Glass and other wearable devices may soon
augment smartphones for rock bolt technophiles.
The researchers tried to teach Baxter how to handle knives while
working as a checkout clerk in a mock grocery store, and no one was
eviscerated.
As
the robot considered various ways of holding the knife while it was
being checked out at the cash, researchers manually guided it through
the process, showing it how to keep the blade away from them.The machine
presented a number of possible ways to move the knife that users can
choose from. Remarkably,But cyclists here said the work is only a small
start on what needs to be done.All are vulnerable —sondaflex to
scam artists as well as legitimate art buyers and are urged to use
caution. it didn't suggest a rapid stabbing motion.In fact, it learns to
handle the knife safely in only three iterations of "corrective
feedback" from the user in the experiment. It can also apply this
learning algorithm to new situations, for instance handling eggs more
delicately than a cereal box.That would be a necessary skill to know if a
robot like Baxter ever works as a chef in a restaurant or home,
according to the researchers.
"We give the robot a lot of flexibility in learning," Ashutosh Saxena,Scientists can sound the alarm if the sensors knife sets and
algorithms determine an earthquake is on the way. a Cornell assistant
professor of computer science, said in a release."The robot can learn
from corrective human feedback in order to plan its actions that are
suitable to the environment and the objects present."The research is to
be presented at a Neural Information Processing Systems conference next
month.Start with fiery Charred Octopus or the Guacamole Trio, which

new freedom or diamond core bit prevent
injuries for industrial workers handling heavy loads. Would you trust a
knife-wielding robot to come just inches away from you?That's exactly
what one Cornell University professor did when he attempted to train a
robot on a supermarket checkout.A video released by the New York-based
research team shows the knife coming dangerously close to Professor
Ashutosh Saxena's body.
