Imagining robots part
of human world is a common buzz because some human must design and build,
Program it, to serve its purpose but it’s all mechanical. What happens when the
robots start learning everything by itself – ROBOT DEXTERITY. The irony of
robotics is “What’s hard for humans
is relatively easy for robots, and what’s easy for humans is nearly impossible
for robots.”
Dexterous Manipulation
is an area of robotics in which multiple manipulators, or fingers, cooperate to
grasp and manipulate objects. Dexterous manipulation differs from traditional
robotics because they are mainly the object-centered ones. That is, the problem
is formulated in terms of the object to be manipulated, how it should behave
and what kind of forces should be employ upon it.
In General case a robot
can pick an object as programmed like Location co- ordinates, size, shape,
color etc. if any of the programmed specifications changed the robot fails.
This is where ROBOT DEXTERITY masters the technology. It will help the robot to
manipulate the object with trial and error method. This improves the efficiency
and it rises to the next stage “self-learning Robots”.
“Dactyl”
a new advancement is a system for manipulating objects using a Shadow
Dexterous Hand. For the
Re-orientation/Self learning there are few things first robotics should
expertise at first. Real world experience, High Dimension control, Noisy and
partial Observations, Manipulating more than one object at a time. The problem is Traditional robots can easily provide enough data
to train complex policies, but most manipulation problems can’t be modeled
accurately enough. Training directly on physical robots allows the policy to
learn from real-world physics. Domain randomization
deals with simulation which is designed to provide a variety of experiences.
This gives robots learning in simulation, gather more experience quickly by
scaling - up, and by de-emphasizing realism, tackle problems that simulators
can only model approximately.
The
new Robot “MuJuCo” with Dactyl has been built. This copies the simulation by
seeing the other one. Example if a human turned an object in a particular direction
the robot copies the simulation and places the object in the same direction.
This is happening cause of the robot can manipulate
the object by repeatedly making contact with it. Dactyl was designed to be
able to manipulate arbitrary objects, not just those that have been specially
modified to support tracking. Dactyl uses regular RGB camera images to estimate
the position and orientation of the object.
The important factor is tactile sensing is not necessary to manipulate real-world
objects and Randomization developed for one object generalize to others with
similar properties. The key players in this area are the
Open AI
